CPU Overclock List & Discussion Thread

I think the name describes it all - You can discuss any and every thing related to cpu over clocking here - when you have reached a nice speed by ocing the cpu and you want to show off this to the others just post in here according to the rules and I'll list it in here ;-)

Before OCing read this :

> I don't take any kind of responsibility on how the information mentioned in this thread or posts will be used.
> If you want to OC the cpu or any related components do it at your own risk.
> Make sure you have proper ventilation and cooling equipment.

Here is great chart by asigh that will help you understand the logical steps behind OC

Digit Technology Discussion Forum - View Single Post - Overclock List & Discussion Thread

Some Useful OC related Tools :

CPU-Z, GPU-Z, AMD Overdrive, CoreTemp, RealTemp, Orthos, Prime95, superpi, wprime, OCCT

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Rules : ( Updated on 17th Jan 2012 )

From now on You have to add a CPU-Z screen shot of CPU, Memory and Mainboard tab along with your forum id / user name and date clearly visible on a notepad / wordpad window and post in the format mentioned below

Here's an example post ;-)

@ amitash - Nice OC you got their on core i7 920 with that x58 board. 4Ghz just with 1.28V is just great

re: Overclock List & Discussion Thread

^actually tats the weird part...its stable 1.28v at 3.99-4Ghz, but even when i want 4.1ghz bootable i need 1.325v...max i booted was 4.3ghz with 1.36v

re: Overclock List & Discussion Thread

Post the multiplier like in your pic it's 17X
Post the Vcore under load - measure it by running prime95 stress test & cpu-z side by side.
What's your set vcore under bios - is it 1.33V ? as I can see your idle vcore under windows is 1.382V

Do edit your post and add in those details

re: Overclock List & Discussion Thread

Sorry to interrupt but whats the point in posting overclocks in this format ? If you want to gather info about clocks by people which are 24x7 capable then it makes sense if you make it mandatory to include a screenshot where in cpu-z, SuperPi32M/Wprime 1024M / Prime 95 for 30 Mins run should be included then only this thread would prove useful.

This is just my personal opinion though.

re: Overclock List & Discussion Thread

^Hey, it counts a lot. Without a stability test, we won't know stable clocks, will we?

re: Overclock List & Discussion Thread

Thanks a lot, topgear, for starting this thread. I am relatively new to OCing and I am sure I shall learn a lot from this thread.

BTW amitash's rig seems pretty close to mine, down to even the mobo! I guess I can learn directly from his experience in OCing. Am I lucky or what!

re: Overclock List & Discussion Thread

@Sjoardar

AMitash is using water cooling , u use core i7 - post ur own way of OCing ???

Totally agreed...stable OC's are what really counts...

BTW somethings weird...with my hd3870x2 + core i7, i could clock 4.2ghz stable, but with the 295, i can barely manage 4

AMitash is using water cooling , u use core i7 - post ur own way of OCing ???

There will be no difference in OCing methods...only the extent to which it can be achieved...and anyway the cooler i have isnt something great...I would say its equal to the new TRUE 1366 edition or the megahalem...But those things cost as much and im afraid they may be too heavy and bulky to offer air flow....and w/c cooling jus looks so much cooler so went for tat.

P.S. damngoodman link to your wallpaper please!

I am not yet ready for OCing my new rig. Not until I get a good aftermarket CPU cooler. I have chosen Noctua NH-U12P SE2 which includes two 120 mm fans. Let's see when it arrives.

Comments:
System is stable. No crashes. The only issue is that I am not able to get my RAM upto the designated 1066Mhz. The max I can get it is around 1016Mhz. I guess will need to tweak the NB voltage a bit. But am happy that I stretched it to 4.00 GHz. (Approx. 43%)

Have not OC'ed my GPUs that much. They seem to be doing the job. But yes they both get stressed during games. The OC definately helps that.

Am really happy with the Coolermaster Hyper 212. It does the job well. Without it my OC would not be possible.

Friends..have updated my OC proof images/data. Now you can see:

OCCT run of 40 mins.
Note the timer, it shows 19min, 7s. It runs on a reverse decrement.

Temperature log for above:

A Crysis Warhead run. (~20 mins)
CoreTemperature Application is logging the temperatures every 30 seconds. Graph created in MS-Excel.
*img231.imageshack.us/img231/1604/crysisrun.jpg

I let the system idle for around 3 minutes, temperature is approximate 38C. The CPU load hits after that, and the temperature soars. Average is the pink line ~54C

re: Overclock List & Discussion Thread

^now that is a detailed post. Great OC man! Seems you are the only guy here with CFX for GPU's!

re: Overclock List & Discussion Thread

^^ LOL MAN
58degreee :O
On load
62-64:O on CM690 :O
Man you gotta Kiddn me..thats Pretty High

Ram : Corsair XMS2 CM2X2048-8500C5 4 GB DDR2-800 DDR2 @ 1016 Mhz.

How these are 800MHz they Should Be running on 1066MHz By default
Somethings not good seems

However When I did OC on My E7400 before @ 3.98GHz
Idle was 31-33degree only and on load after 1.5hrs OCCT it max crossed 58degree which is near to your Idle,....

Man that's My Xigmatek's Thor's Hammer
Beware of that Hyper 212 Man

Theres nothing to be sorry

You have got a suggestion and you posted it

At first I thought that I would made it mandatory to post a orthos, prime95
1 hour test along with a cpu-z screenshot to list some stable oc. But I abandoned that idea coz I have seen instances where people can run prime95 4 hour test without prob but it fails in normal tasks like installing app or the OS due to OC.

I believe all the OC's posted so far in this thread are stable but I'll make it mandatory add a cpu stress test app screenshot along with a cpu-z screenshot & only then I will mark it as stable.

OC is alos a bit off show off thing thing as you know coz you reached 6.1Ghz on Phenom II X2 550 but your posts have only screenshots of running spuerpi 32M @ 5.8Ghz ? One of your comment :

I dont do all this to run Prime man Its purely for benchmarking.
Next time I take it sub zero I will try to run those crysis benchmarks

Many people love to show how far they can reach with their config but when it comes to stability it a different thing altogether so from now on I have decided to mark only those OC's as stable which osts have a cpu stress test app screenshot along with a cpu-z screenshot

BTW, in your AMD Phenom II X2 550 OC thread what speed I should take as stable ? Is it 5875MHz ( super pi 32M test ) ? or wPrime 1024M @ 5223MHz ( wPrime 1024M Test ) ?

Thanks for your appreciation

@ asigh - Nice OC with that Hyper 212

@ to all - - do edit your posts and add some cpu stress test screen shot along with a cpu-z screen shot

@ thunder.02dragon - The OC you posted - is it stable ( I am assuming so )? If it is please post the screen shot defined above or in the 1st post rule 2

re: Overclock List & Discussion Thread

@ Asigh

PLZ Use the PUSH PULL , Get another fan for HYPER 212

Thats cool man , BTW i think u never care about ur Processor or Mobo , thats massive FSB increase . Dont get ur Mobo fried !! :))

I cant wait to get some coolers , soon i ll be moving to bangalore then i do Special OCing

@ thunder.02dragon

There is no big difference between TRUE 120 / hyper 212 / thorhammer !! all comes under up to 5deg difference !

re: Overclock List & Discussion Thread

Nops Buddy my IDle has huge diff than yours I think..so do load as on heavy gaming it reached only 48degree but ont long OCCT it was 58deg... on E7400

@topgear
Sorry Buddy I have changed my proccy of E7400 so cant post the results more
E8400 @ 4.3GHz was long before mate dont get tym now and during format occt results got del ;(
Damn....
However will try again if i get time and as well update the post...dont wrry

Beware of that Hyper 212 Man

Where did you see that the CPU is idling at 58C. That CPUID image is with GPUs under stress..(running OCCT)so of course the CPU will be used too. That is an ideal game condition. So during synthetic tests..I hit around 67C-68C during load, and via gaming..it stays under 60C. My idle is a cool 39-40C. I think the Hyper 212 is great.

I have played games..and ran temperatur loggers..never even touched 65C. So I think I am in the save limit.

No ways do these memories run at 1066Mhz default. JEDEC #1 is 266Mhz = 532 Mhz and JEDEC # 2 is 400Mhz = 800 Mhz. Only the EPP (extended performance profile) is rated at 533 Mhz = 1066 Mhz with 5-5-5-15 timings at 2.1 volts. Memories cannot always run at the specified standards. I have seen people take them beyond 1066 Mhz. I am close to that limit. Need to play with the NB voltages.

PLZ Use the PUSH PULL , Get another fan for HYPER 212

Thats cool man , BTW i think u never care about ur Processor or Mobo , thats massive FSB increase . Dont get ur Mobo fried !!

I cant wait to get some coolers , soon i ll be moving to bangalore then i do Special OCing

@ thunder.02dragon

There is no big difference between TRUE 120 / hyper 212 / thorhammer !! all comes under up to 5deg difference !

MOBO wont fry...seem to be in safe limits..temperatures..seem stable. The screenshots I pasted..I will never reach them during gaming (most stressfull situation), OCCT/FURMARK burn the hell out of hardware....!!!!

re: Overclock List & Discussion Thread

As a safe rule guys:

1. Lets not make fun of others equipment and OC.
2. If we want we can diplomatically make a suggestion/give advice.
3. All OC should be supported by some screenshots/graphs.

I will be updating this thread with a 45min run of OCCT and some temperature logs while running Warhead all maxed out. Not being able to upload images to imageshack.

What I could suggest.

1. For CPU one can run OCCT and post the graphs which auto-generate.
2. For GPU one can run Furmark and monitor temperatures using any GPU temperature monitoring software (ATI CCC, ATI Tray tools, CPUID temperature monitor) and make screen shots. This stresses both GPUs if Xfire/SLI is enabled

Was it stable @ 4.3Ghz when you OCed e8400 @ 4.3Ghz ? If yes why you have put it to 4.1Ghz ?

If you are using a e7400 now why you are still using e8400 @ 4.1Ghz in your suiggy

Your psu query was related with gfx card and cpu. You could ask that in
All Graphics Cards related queries here thread - it's a very active one and desibond is also there too

re: Overclock List & Discussion Thread

@ desiibond - yup, That's enough

@ hellknight- sis sandra cpu benchmark is good but is not best to determine the stability of OCed cpu. You should have used Prime95, orthos, superpi32M, wprime1024M or OCCT. If you jhave the time do test your CPU @ 3.6Ghz with any of the above cpu test app and post the pic. BTW, I've listed your's as stable

For the 24x7 OC... I dont keep this OC every time.... 1-3days even 5-6 hours I OC as the electricity is not good here too much cut off and my 600VA is not good for my rig with TX750 so fear of getting f*****
I mainly use stock speeds...right now its stock...
AS INTEL DOES NOT GIVE WARRANTY OF THE OVERCLOCKED PROCESSORS
Why risking valuable things...
OC is fun and I love to do but cant afford these cost again and again

re: Overclock List & Discussion Thread

^^

You cannot support a TX750 using a 600VA ups. I had an APC 600VA APC it would not support my TX650 during load. Get a 1.1KVA.

Nor do motherboard / RAM / GPU manufactures. Its all on 'ones own risk'.

Topgear....I would suggest to post a disclaimer on the first POST...a small warning about overclocking. I am sure..people are going to come in here...read our post..and start to OC. There are many factors to consider before starting OC.

re: Overclock List & Discussion Thread

@ asigh

wat is maximum increase of FSB in the AMD 790GX chipset its noted as 200 its not going above 220 , i am getting BSOD ??

wat to do

re: Overclock List & Discussion Thread

decrease FSB a bit, increase multiplier, decrease DRAM frequency. That may do.

if you are getting BSOD, that means that it's not a stable OC.

re: Overclock List & Discussion Thread

wat to do

Work on one parameter at a time.

1. Bring you RAM back to default. (JEDEC 1)
2. Put your vCore at 1.4
3. Increase your FSB and multiplier so CPU speed goes up by 200 MHz.
4. Run for stability.
5. Lower vCore

Keep doing 3 and 4 till you reach a stable point, then slowly lower your vCore and again test for stability.

Basically you have to play with FSB + multiplier + vCore till you hit the most stable setting with good temperatures...

THEN

...bring your RAM timings and voltages to EPP.
...start to increase the DRAM frequency slowly..and check for stability.

That is huge...5.3 Ghz, with a lot of volts going into the chips. Is that LN2 container..full or empty...cannot make out.

Anyways..its doing a great cooling job.

Timings look good compared to the standard 7-7-7-24.

By the way..I see a lot of people using Super PI...here. Does it really stress the CPU well...does it also stress the RAM..?

Yes its a custom made full copper LN2 container.
Lol that Ram is rated at 1333MHz 9-9-9-24. While here it is doing 1600 6-6-6-18.
Try doing that on cheapo DDR3 kits and see what happens ;-)

Well, I have mentioned that this is the worst AM3 CPU I have.
Also this is not the best score ;-)

Do not consider these as stable because I have used LN2 which is not a practical cooling solution.

re: Overclock List & Discussion Thread

@top gear my oc is actually approx 51% (50.6%) not 53% as stock speed of i7-920 is 2.66Ghz not 2.60Ghz...And im on water btw

re: Overclock List & Discussion Thread

@ darklord - That's why I have not tagged it as stable. BTW, removed stable tag from all LN2 cooled cpu's as it not a practical cooling solution.

@ amitash- corrected that and tagged your OC as water cooled

re: Overclock List & Discussion Thread

If the stock speed is 3Ghz , if we OC to 3.4 with same Vcore then there will be any temperature increase ??

the huge difference or little ??

There is no relation to CPU speed to vCore to temperatures. It varies chip to chip, system to system. One has to experiment, and get the feel of the system.

For example, till I was pushing in 1.2V my system used to stay below 34-35C, post that it shoots up past 42-43 (idle).

re: Overclock List & Discussion Thread

Wow...great OC.

I must say "we" made a good choice buying the Hyper 212. Personally I have always been satisfied buying Coolermaster Products. They are the masters of cooling...!...Be it TIM, fans, Coolers, cabinets...not used their PSU but am sure they are good. I previously had a Cool Viva Plus on my old 8500GT...OC'ed it like crazy.

By the way..can someone start a 3dmark/Vantage thread. We all can post their. Or should we just post it here...but it will mess it up...???

Wat is temp now on HD4890 OCed to 1Ghz ???

re: Overclock List & Discussion Thread

^^ The OC'ed one is the slave GPU. Since the 2nd GPU which I got was stocked at 1000/900, and my first one was at 975/850. So to make them match I OC'ed the 2nd one to match the first one.

The slave one runs slightly cooler.

Idle:
GPU1: 67C
GPU2: 62C

Load: (Furmark)
GPU1: 87C
GPU2: 86C

Load: (Gaming)
GPU1: 78C

Obviously FURMARK burns the hell out of the GPUs.

^^ Seriously not bad for the Reference coolers , u can use arctic accelero S2- cause i was thinking to go for this one for my GTX260 (cheap GPU cooling)

re: Overclock List & Discussion Thread

OK! I have Athlon X2 4400+. I can overclock upto 2.8Ghz without touching vcore. The thing is whenever I have to overclock I just have to disable AMD's Cool 'n' Quiet as the CPU Frequency Scaling (i.e. the throttling down of frequency) feature does not allow frequency over 2.3 Ghz and and disabling Cool 'n' Quiet disables CPU Frequency scaling as well.
The thing is I want to have such that the CPU Frequency Scaling works with 2.8Ghz and also throttles down when necessary. Any ideas?

Honestly cannot be bothered to remove the cooler of the GPUs. They can easily sustain temperatures past 90C. (That is why we pay so much for them). And I doubt I will need to OC. Am satisfied with the Xfire.

You planning to dismantle yours..????

Just being logical here..never OC'ed an AMD.

1. Which motherboard you have.
2. What is the max FSB (1) supports.
3. Is the multiplier unlocked (I think you can do it on AMD chipsets).
4. Which multipliers you tried.

I think throttling should still work. How you know it is not working...?? If at certain settings you are able to get the CPU speeds up high, and pass the stability tests...then be happy and leave it there...!

re: Overclock List & Discussion Thread

@LFC_fan: AFAIK AMD cool n quiet is quiet inefficient on the older amd models like the 4400+ and hampers OCing unlike intels speedstep...you will just have to disable it...alternately u may try a bios update to see if it helps

@asigh: he has an amd procy so no FSB and ocing is a totally different process and afaik multiplier is locked on non black edition procys

re: Overclock List & Discussion Thread

@ asigh AMD proc's have had an integrated memory controller since a long time, something which Intel has only since core i7. So, AFAIK, just like you OC the core i7 920, which has no FSB and no unlocked multiplier, same way its for the AMD proccy's. I have not oc'ed my proc yet so I can't help you with this much as of now.

It would be better to mate the 5870 (if you get it) to the high-end i7s. There are issues of CPU bottle necks. Though even if you use a Phenom 2 940 or P55 i5/i7 or even a high end Quad you will get phenomenal performance -- but you will not extract all the power from the 5870.

@ asigh AMD proc's have had an integrated memory controller since a long time, something which Intel has only since core i7. So, AFAIK, just like you OC the core i7 920, which has no FSB and no unlocked multiplier, same way its for the AMD proccy's. I have not oc'ed my proc yet so I can't help you with this much as of now.

Ok...did a bit of research. For the X58 chipset unless you have the extreme edition i7s the multiplier and FSB is locked. The QPI has to be changed, and that is done using the Base Clock. BCLK. Once the BCLK is changed it moves the QPI speed respectively. But voltages and RAM timings can still be manually changed -- if the chips need extra power.

Could anyone place the procedure here for AMD chips. Or if they want they can make a similiar chart like have (use Visio). Else I can make a chart for AMD chips - if someone can tell me a detailed method.

It would be better to mate the 5870 (if you get it) to the high-end i7s. There are issues of CPU bottle necks. Though even if you use a Phenom 2 940 or P55 i5/i7 or even a high end Quad you will get phenomenal performance -- but you will not extract all the power from the 5870. And is not that..what we all want. To squeeze every drop from our systems..and then take it a bit beyond.

I got this Phenom 2 940 cause some day i wud sure OC over 5Ghz , cause Phenom 2 940 Hold the record of 5.5ghz using H20 .

All i need is vantage points any ways i should touch 45000 to 50000 in vantage mark . GTX 295 3 ways is to costly for me & GTX 295 i cant OC much ! i need to wait until HD5870X2 should be launched

Till now 44750 vantage mark is the Highest scored with Phenom 2 on 6.8Ghz with HD4870X2 - it wud be worth to get HD5870X2 , so i can manage to save to money for Higher end proccy .

Anil - i dont think Corei7 920 compared to Q9550 & 940 dint do much performance in OCing , Though i7 920 cannot be pushed over 4-4.2 even with higher End cooling !

Its not about the OCing factor. Its how fast the CPU can feed the data to the GPU. Prior to this it used to get bottle necked due to the North Bridge. The QPI has corrected that, so more data can flow via tha x16 channels.

You should not have quoted my image topgear. That is a waste of bandwidth. :))

And I have a 17" CRT box monitor, and I have kept the resolution of the image somewhere around 800 pixels wide. It is not stretching the image at all.

Thumbs need an added click, so I never post them, although mobile users will want to attack me for saying this. :ashamed:

This is strange, as I am on FF and my screen resolution is 1152x864.

Anyway, next time around, I'll try and lessen the resolution. Btw, now I am at 3616MHz, but I can't get it stable even after pushing vcore to 1.392V. I think I'll google up some AM2+ overclocking guides. :s

re: Overclock List & Discussion Thread

^^ You need to pump up more voltage ( around 1.5V ) and you can reach around 3.8 GHz with 1.52 vcore

re: Overclock List & Discussion Thread

^^ Amd recommends only 1.45 max limit for Phenom 2 940 1.50 if its water cooled Or L2n

re: Overclock List & Discussion Thread

Did AMD also specified some speed limit with 1.45V vcore ??

If you have proper cooling you can safely pump u 1.5V - If you want to achive a certain speed then OC does not always stays within manufacturers specified limit.

Take a look at these :

*ixbtlabs.com/articles3/cpu/phenom-2-overclocking-p1.html
*www.techspot.com/review/142-phenom2-overclocking/page2.html

So phenom II X4 940BE requires that much voltage ie around 1.5v to reach 3.6 GHz and beyond and for cooling I think it's safe upto 3.6 GHz with good air cooler

Here what tom's hardware guys are saying :

Overclocking with a Black Edition Phenom II is as easy as it was using previous Phenom chips—an unlocked multiplier remains the most straightforward way to scale up and down 100 MHz at a time on a 200 MHz reference clock. With 19.5x keyed in, we set the processor’s voltage to 1.55 V, which was the maximum AMD recommended for air cooling.

re: Overclock List & Discussion Thread

^ why CPU-Z is showing that your CPU speed is 3079 MHz ( close to 3.1 GHz ) - did you enable some features like auto tune/auto/turbo OC in bios if not what's the actual speed 2.8Ghz or 3.1Ghz ( as cpu-z is showing this ) ?

Try updating bios to the latest version and try a updated version of CPU-Z itself.

Try running OCCT cpu for an hour and it will give you a fair idea about temps and stability of your cpu and post the generated screenshots ( by OCCT ) in here.

BTW, The temp you are getting with 3.1 Ghz ( or 2.8GHz ) and with the stock HSF is perfectly normal.

its normal is 2.8 and yesterday i overclocked it to 3.1.and then ran the prime test and posted those pics.and again at night i ran the prime test and left it for 8-9 hours here is its pic.thank you.can i do some more?what about that vcore?

re: Overclock List & Discussion Thread

With just 1.224V load vcore and stock HSF you are getting marvelous OC.

if you want to push more you will need to up the volt and you will need a better cooler.

re: Overclock List & Discussion Thread

hey i upgraded my bios version from 1.0 to 1.1 and now my vcore has been further decreased automatically,at idle it is 1.000 and at bios the vcore is written as 1.234 at first it was 1.304.so how to increase the vcore and is there any specific value of vcore which i should set?up to what temperature my system can go?
here is a link which tells complete detail about my processor
*www.cpu-world.com/CPUs/Pentium_Dua...1PG0722ML (BX80571E5500 - BXC80571E5500).html

re: Overclock List & Discussion Thread

After Upgrading the bios are you running your cpu at default settings or you have OCed with the new bios version as well.

Before and after updating bios it's always recommended to load the default values -after a successful bios update you will need OC again by changing fsb, ram speed and volt values.

I guess your cpu is running at stock speed of 2.8 GHz after the bios update. If so you need to OC again.

Try to OC your CPU with the previous bios values ( like 3.1 GHz/1.3V etc. ) and see if you can get a stable OC and don't forget monitor the voltage and temps as well.

To change vcore value you have to change it manually and set it to 1.3V.

re: Overclock List & Discussion Thread

where i have to change manually? In my bios HW monitor section is there it shows the vcore,+3,+5,+12 volts and there i can't change those values.

I have overclocked the cpu again to 3.1GHz after loading bios to default and the vcore is 1.234 and now my ram frequency is also increasing with the fsb oc(it is now at 440 before it was 400) and latency changed to 6-6-6-18 and ratio to 1:2.is it ok?

Can i overclock by increasing the multiplier?which one is safer fsb or multiplier?

until what temperature can i overclock?it is now at core1 is 59C and core2 is 54C.

Is there any use of overclocking pci?

re: Overclock List & Discussion Thread

your bios should have this option - don't look for it in HWmonitor section though.
It probably under the section where there are options for changing OCing. Read the mobo manual carefully.

As you have OCed your ram is also being oced as the CPU FSb and Ram Speed are in link mode - try selecting some preset ratio though and see which speed is close to 800 MHz though speed upto 880 MHz is safe for value series ram modules. BTW, what's the brand of your ram.

Your CPU don't has unlocked multiplier so you won't be able to increase it - you will have to OC it using FSB way but you may lower the multiplier and set higher FSB. For eg :

12*260 to get 3120 Mhz but it will incraese your ram speed upto 1040 Mhz if you don't select proper FSB:RAm speed Ratio.

You are safe upto 68C under 100% load - use OCCt and run it for 1 hour at-least - it will give you every kind of results like voltage/temp/speed/workload of test condition.

It would be great if you provide me the manual download link of your mobo.

re: Overclock List & Discussion Thread

in my mobo i didn't tried increasing the multiplier but in cpu oc section when i disable intel speed step technology then mobo will allow me to change the value of multiplier.so is it possible for me to change the multiplier?

i

have seen in bios some nb volt,+1.5 volt,+3 volt......options which i can change but there is no option as vcore.so by changing these volt can i change the vcore?BTW my vcore has now automatically came to 1.304v

.

In the above link which i have provided for info about my processor says that my vcore operating limit is 0..... to 1.304 can i go behind this 1.304 vcore?

Here is the link for the manual of my mobo
ASRock > Products > G31M-VS2 > Manual

thank you.

re: Overclock List & Discussion Thread

Like I said you can lower the cpu multiplier but ou won't be able to set it any higher than 14x.

some low end mobo don't allow to change the cpu vcore. They just provide suitable volt if you incrase FSB or OC - but this provided volts always not perfect and thus creates instability and limits the Oc capability of low end mobos.

If you want to go beyond your CPu vcore limit you have to ensure you have proper cooling for your cpu.

Will check out the manual and comment later.

re: Overclock List & Discussion Thread

is it vcore and vtt voltage are same?

re: Overclock List & Discussion Thread

no. vcore is the volt of the cpu ( needs more vcore if you increase cpu speed say 3.1 Ghz from 2.87 ) and VTt is FSB volt for mild OC such as yours you don't need to cahnge that but if you are going to increase the FSB more than what your mobo can support you have to increase it -

say you want increase your CPU FSB to be 1600 MHz instead of 800 MHz but your mobo supports default only 1333Mhz - so your cpu will be runningat a insane speed of 5.6 Ghz or if you lower the multiplier to 10x then your cpu will run at 4 Ghz - just don't this right now and it's just for an example - for this kind of OC you will need some extreme series mobo and of-course liquid or LN2 cooling.

re: Overclock List & Discussion Thread

I getting a weird error , I never get the kinds error

that's the most weird error I've ever seen related to OC.

You're getting this error while in windows right ? which app is showing you that ? is the OC stable enough ? you've OCed using Bios or you've used overdrive ?

Have you set the DRAM voltage to the EPP settings.? Also if you face NB stability issues, you may need to increase the MCHv, but be careful here.

re: CPU Overclock List & Discussion Thread

^^ wat is EPP setting ??

In DRAM voltage i have to set manually or Auto its gigabyte Board

re: CPU Overclock List & Discussion Thread

Check the SPD tab for the memory it show show the EPP (extended performance profile) settings. Set the RAM voltage 'manually' to that. And remove all 'auto tuning' functions..not sure what they would be for your board, but still like EIST/Spread Spectrum.

Do you have black edition cpu ?

looks like your cpu is not getting enough juice at 3.7 GHz - you need to increase the volt.

Set CPU volt to 1.4625V @ 3.7 Ghz ( cpu FSB 255x15 )

I don't has much experience in core i5 OC.

I won't recommend Ocing core i5 750 more than 3 GHz with stock HSF as the stock HSF is not that great. It looks like it was built for old generation 65W TDP cpus and core i5 750 has TDP of 95W.

But as long as the temp is under 70C you can OC it further.

With a good after market CPU cooler you can OC the cpu upto ~3.8-~4.2 GHz.

HD5770 can be OCed using Riva Tuner. Expect to get ~75-~100 Mhz clock speed and ~600-~800 Mhz mem clock increase.

BTW, do remember to keep the tempo under 85C though.

re: CPU Overclock List & Discussion Thread

Need some suggestion regarding Phenom II 955 overclocking. I am using AMD overdrive to overclcok and reached 3.6 GHz safely by just increasing the Multiplier to 18X. It is stable most of the time but sometimes system getting hanged when playing games for several hours.
I need suggestion regarding stable voltage, memory multiplier and NB voltage values for stable overclocking @ 3.6 GHz to 3.8 GHz.

re: CPU Overclock List & Discussion Thread

^^
Better to do it via BIOS. Desktop utilities are not that reliable.

re: CPU Overclock List & Discussion Thread

Actually I nee some suggestion regarding the stable values for CPU voltage, memory multiplier NB voltage etc for a stable 3.6-3.8 GHz overclock. Once done, I will change the values in BIOS. AMD Overdrive even the feature to update the BIOS directly and I've tested it... working fine.

re: CPU Overclock List & Discussion Thread

Not every mobos and cpus can be OCed with same values even if they are from same series. I'll suggest you to wait till your new mobo arrives.

BTW, If you can ditch Over Drive and OC using bios options. Ocing through Bios is more fruitful always IMO.

AMD OD can handle only multiplier increase , 18X is the maximum increase for 955 , if u raising multiplier the heat will increase if u have good mobo reduce the multiplier then just increase bus speed slowly to reach the potential speed !!

Make sure ur RAM has heat spreader !!

re: CPU Overclock List & Discussion Thread

^^ I think 955BE has unlocked multi so why it's limited only at 18X - is this a limitation of OD or the cpu itself ?

If you run your Rams at specified speed or 10% more I think it's safe even without heat spreader for DDR3 1333 Mhz modules. They though have higher speed than DDR2 their volt rating and power consumption is low so the heat generation will be a little bit less.

Make sure to set ram and FSB multiplier correctly and always try to oc with a third party cpu cooler installed.

re: CPU Overclock List & Discussion Thread

^^^ I just mentioned that if he increase more than 18 the heat will be more ,, 955 is almost same as my 940BE the heat is intense .

re: CPU Overclock List & Discussion Thread

^^ Ok .. I got it - The higher TDP rating ( more power consumption ) is the reason for the heating issue I guess.

re: CPU Overclock List & Discussion Thread

Hey guys I was checking some stuffs in BIOS (Specs in my siggy) and found this under AI Tweaker, there is an option, CPU LEVEL UP- Auto, i7-975-3.33GHz, i7-Crazy-3.7GHz and AI Overclock Tuner- Manual, Auto, D.O.C.P, X.M.P. Now my query is, is this overclocking? As far I knew overclocking could be done only by additional softwares, but is it possible via BIOS?
And if I do overclock which speed should I choose? 3.33 GHz or Crazy 3.7 GHz and I will also like to be informed by the Advantages and Disadvantages if I overclock. Is it really needful and Safe? Will it increase my CPU temperature much?
Thanks in advance.

re: CPU Overclock List & Discussion Thread

First of all what you knew till today was partially true. Oc can be achieved by software and Bios ( HW ) both. Mid to high end mobos comes bundled with or supports some kind of Oc apps with which a limited amount of OC can be gained. But if you want a TRUE OC and want to keep every possible setting under your control while OCing then you should better use Bios Ocing as it's the best way to achieve OC and push you hardwares to the limits. Even if you get a mobo which don't support software OC most of the chances are it has tweaking option in bios to do some OC.

Obviously that's OCing. That's just an option to automatically OC your cpu using bios ( Read Ai option ). That's AI ocing is a good starting point to test a little bit OC but it won't give you precise control over everything while ocing. To do that you need to do the necessary changes in bios ( like cpu volts, qpi link speed, mem speed, mem ratio setting, mem volts ) manually.

For you 3.33 Ghz should be a fine starting point. At 3.7 Ghz your cpu will use more power ( read volts ) and that will increase your cpu temp as well.

Before ocing note the temp of your cpu using real temp, measure volts using cpu-z. After setting a little Oc in bios ( say 3.33 Ghz ) again run those apps and this time run a OCCT or prime cpu stability/load test to know if the oc is stable. If it's stable and the temps are in safe limits you can proceed further.

re: CPU Overclock List & Discussion Thread

Thanks, how will I run OCCT or Prime CPU stability/load test?

Anyway I tried to OC to 3.33 GHz, this is the results before and after Ocing,
Before- CPU-Z Validator 3.1
After- CPU-Z Validator 3.1

And Real Temp shows temp as- 39-35-38-32, so it's a little increase. But the CPU Voltage as you can see is @ 1.2V.

and this is the Sensor Test result after OCing,

UPDATE- OC'ed to 3.7 GHz, Core Voltage is @ 1.34V. Normal Temp is like- 43-44-42-37
Here is the sensor test and CPU ID screens,

You can see @3.7 GHz sensor test the temp reached up to 81°C, Is that normal?

Please mention if anything I did wrong or the results.
Thanks in advance.

re: CPU Overclock List & Discussion Thread

^^
The aim of any OC (not idiotic benching) should be:

1. Highest possible speed.
2. Lowest possible temperature.
3. Stable system after various stress tests.

Would advice you to use the Intel Burn Test (with RealTemp/CoreTemp for temperatures) to truly test the integrity of your OC. Also once you hit the speed you desire, try to keep lowering the vCore till the system is unstable. Remember it has to be lowest vCore+highest speed.

High heat and increase vCore kill the CPU, with the latter coming first....!

Best.

re: CPU Overclock List & Discussion Thread

You should better keep the cpu temp under 70C to be safe. Try lowering your CPU vcore manually and keep it reducing untill you find the most stable vcore @ 3.7 Ghz.

Download OCCT and Run the CPU load test for at-least an hour and this will give you all the infos you need and post the results in here. Keep a close eye on the temps while running OCCT with 3.7 GHz speed using Real Temp.

Thanks, I downloaded OCCT and Ran it for just 10 minutes as I had sort time, will run for an hour laetr. @3.7 GHz the max temp reached 78-77-76-72 (by Real temp) when in OCCT it was set to- Large Data Set and High priority.
So the max temps are not under 70°C, so I think it's not safe, right? Can you tell me the reason, is it my cooler?
and one more thing, I changed the VCore to 1.1V in my BIOS settings before OC'ing, but then when I press the power button the PC is not turning on. I had to re-open the Processor and then re inserted again. So it's kinda weird. Can you tell me what to do to turn my PC on without opening the Processor?

Thanks and Regards.

re: CPU Overclock List & Discussion Thread

The vcore is shown as 1.2V is when your cpu was in idle state with just 0.7% load. So it's clearly not the load vcore which I've asked for.

When you are setting vcore values in bios it's for cpu load voltage not idle.

You set you cpu load voltage way too low and thats why your PC refused to boot but in such case you usually have to just clear the CMOS setting by jumper ( read mobo manual ) or removing and reinserting the big cmos battery on mobo and some mobos has dedicated switch to clear incorrect CMOS setting.

While running OCCT/Prime 95 keep cpu-z/real temp open to know about the load voltage while your cpu is being stressed by those app fully and that's how you will get know about the actual cpu load voltage.

BTW, what was the vcore in bios @ 3.7 Ghz before you changed it ?

Disable all power saving option in bios and reduce the vcore in small stages ( say - 0.001 or - 0.025 ) not by huge margins until you find the minimum stable vcore for your cpu.

You know what is going to happen one day to you. You will weep when you break your system yourself. What the heck are you doing..? Since the day you got your system you have been doing stuff so haphazardly. Sorry to say this -- but try to be patient. Please.

Do the following generic things:

1. Read up about OC. This and this might help you.
2. When your system locks up due to incorrect OC just reset the CMOS. Am sure your motherboard has a button on the back panel which can be used for reset.
3. Disable all power saving features from the BIOS.
4. Change Windows power mode to performance.
5. Try OC changes in small increments. Be careful here.
6. Use RealTEMP+Prime95 for initial stability test later on use OCCT+IBT. The last two are really harsh -- so try these when RealTemp Passes.
7. Post RealTEMP logs of temperatures if in doubt.

re: CPU Overclock List & Discussion Thread

Guys, now 3.6 GHz overclock is stable. Just done it using Overdrive and created profile. Only using them at the time of gaming. It is perfectly stable now as the temperature is low now. Know you guys are not gonna like OCeing
In full CPU load (using performance mode in Win 7, using Handbrake to encode a 15000 Kbps 1080P Mpeg2 to AVC format) max temp was 64 degree centigrade.
In Battle field Bad company 2 getting almost 15 FPS (now 65 to 68 fps) after CPU and small GPU (Core clock 20 MHz increase, Shader clock 20 MHz) Oceangoing with everything set to highest and 16X anisotropic filtering and 16X MSAA.

Now some more help regarding NB and Ram tweaking. I'm using 2 Kingston 2 GB 1333 MHz C9 modules. Could u guys guide me or provide some good link for Memory overclocking.

I re-checked BIOS settings and if I select 3.7 GHz then the CPU Voltage is - 'Auto' and QPI/DRAM Core Voltage is- 1.43750 V (in RED). So will there be any problem if I continue testing while the CPU Voltage is at 'Auto'? When previously I ran the load test @ 3.7 the Core Voltage was- 1.3 to 1.35V as I checked by CPU ID and I also stated the temperatures when I ran the stress test by Prime95+ Real Temp in my previous post.

re: CPU Overclock List & Discussion Thread

guys i got a tool,asrock oc tuner for overclocking from my motherboard website.when i run this application i can overclock my processor,pci-e etc.,it will be overclocked untill the application is running.
so guys can i use this tool for oc whenever i want?
Is there any effect to the mobo and proccy if i oc and downclock it again and again?
and i don't have any option in bios for changing vcore.BTW my idle vcore is 1.024 and on load 1.184.

re: CPU Overclock List & Discussion Thread

^^never heard to that tool but if it gets the job done for you then you should use it though don't OC pci-e.

As long as you keep an eye on temps and don't let the cpu temp cross 68C you are good to go.

The vcore value you posted is just perfect - there's nothing wrong with it.

BTW, how much you have OCed your cpu using that app ?

you need to disable AI OC and manually OC your cpu to change vcore setting. Follow the links provided by asigh to manually oc your cpu.

1.43750V vcore is way too high - to hit 3.7 GHz you need to set vcore around 1.265v-1.3v - ( may be you need to decrease the multiplier a little bit too ) it's just for an example - you have to find the proper volt by using trial and error method - always keep an eye on the temp - keep it under 70c under load and you will be fine.

If you set a vcore say 1.3v in bios and cpu-z is showing you a vcore of 1.285V or some less value under 100% cpu load it's just an proper example of vdrop. Vdrop is when your CPU voltage drops down than the set value in bios and it's normal.

re: CPU Overclock List & Discussion Thread

550BE can be oced using two ways -

1. by increasing the multiplier
2. by increasing the FSB/CPU Bus Speed

When Ocing you should keep the cpu temp in check and don't let it cross over 65C.

With increased cpu speed your cpu my need additional voltage or you may have to manually tune the cpu voltage while ocing.

stock cooler really sucks when you OC - so if you want to hit some decent speed get some decent cooler first like CM Hyper 212+ at-least.

Read all the posts psted in here, read your mobo manuall carefully and get a decent cpu cooler first.

re: CPU Overclock List & Discussion Thread

i am new at ocing so plz help me out on this guys

first my config
amd phenom II x4 955 be
asus m4a87td evo
corsair vs2gb1333d3
corsair vx550w

i want to mild oc my cpu from 3.2 to 3.4 ghz

now my question is how should i go about it

in th bios there is any option CPU level Up which has following options
auto, 965(3.4ghz) and 3.6ghz
will selecting the 965 option automatically oc my 955 to 965 clk speed??

secondly about OC Tuner Utility
should i enable the automatic ocing with it
as it says it will also oc the ram and since i am using a value series corsair maybe its not such a good idea

lastly what are CPU load line and cpu/NB loadline calibration options
they are turned to auto by default
is it something to do with ocing and should i enable/disable them??

re: CPU Overclock List & Discussion Thread

go through the thread pages, read them carefully and keep cpu temps in check.

Disable all auto OC option - manually crack up the CPU FSB or something like that from 200 Mhz to 216 Mhz - keep every other settings at their default values.

Post a cpu-z screen shot of cpu and mem tab.

Well, I re checked BIOS and set CPU Voltage to 1.2625V, then ran Stress Test by Prime95+Real Temp, it completed the test with Max temperatures at- 68-66-65-63. Then ran OCCT for 15 minutes, Max temp reached, 70-70-68-66°C.
So do you think the temperature and the CPU Voltage is OK now? The QPI/DRAM Voltage was 1.43750V while doing all this. May I know what this QPI/DRAM Voltage is? Should I try to decrease it too?

Attaching some screen shots while was doing the tests. Please have a look. I have also did a test @ 1.28V to see the difference.

Thanks in advance and Regards.
Merry X-MAS to you ALL.:C_xmas:

PS- My room temperature was 23°C.

re: CPU Overclock List & Discussion Thread

Those temps are really nice - now try to decrease the cpu vcore even more untill yu find the lowest possible stable voltage. Decrease cpu voltage in by 0.0050 - 0.0025 volt each time - check the stability and decrease it again.

QPI/DRAM Voltage is memory controller voltage but in case of core i7 cpus it's built within cpu - so a higher qpi volt means increased cpu volts - intel recommends to keep it upto 1.35V but many mobos tends to run with higher qpi voltage than this.

QPI voltage usually increases with the speed of ram. Say with 1333Mhz you would get 1.2V and with 1600 Mhz you would get around 1.32 or may be even higher though there's no perfect rule to this - most of the time mobo automatically provide proper qpi voltage and when you OC your cpu mobo tends to automatically adjust qpi voltage by increasing it which most of the time is more than needed.

So to know about proper qpi voltage you should first two things :

1. What's your Ram speed with the Oced cpu ?
2. What's your RAM ( Memory Module ) Voltage Under bios ?

A simple safe limit rule is you should always keep your qpi voltage 0.25-0.5V lower than memory module voltage.

In your case the qpi voltage is 1.43750V ( voltages upto 1.45V considered to be safe by the experienced users ) - though it's not anything alarming by you may try lowering it a bit - say 1.385V or 1.4V until you find the minimum stable voltage.

I will try to decrease the QPI/DRAM Voltage then. My RAM speed is 1600MHz, but I didn't understand what did you mean by Ram speed with Oced cpu? Should the RAM speed change with CPU speed as well?
As I said before, I did the OC'ing from my BIOS, so under 1.2625V the option was 1.256V and when I checked that the system was okay, but the system froze/hang when I ran Prime95 Stress Test.
BTW- I have a query, How will I save a OC profile in BIOS? I clicked 'Start O.C Profile Utility', then the blue screen moves to a save page, but where and how will I save a profile? I don't wanna run my proccy @ 3.7 GHz all time besides gaming.

As always, thank you very much for your valuable reply and in advance.
Regards.

re: CPU Overclock List & Discussion Thread

in some mobos when you oc cpu using auto settings Ram automatically also gets oced - so I asked about that - post a screen shot of cpu-z memory tab and it will make everything clear.

Read the mobo manual carefully to know about how you can save OC profile in Bios - I've no idea about your mobo.

Prime95 hanged during load test coz your cpu was not getting enough juice while steers testing so you can't say it a very stable OC - Set the cpu vcore 1.28V and test again - run OCCT 1 hour cpu test to know if your OC is stable enough or not.

BTW, if you can remount the Hyper 212+ with some good TIM and see if you can get lower temps under load.

Prime95 hanged when VCore was 1.256V, but it didn't when it was 1.2625V. Still I will run the OCCT for an hour to see if it's well stable or not. (it at least ran fine for 15 mins).
When I mounted the Cooler I applied the CM TIM came with it in the box. I was thinking of attaching an extra fan to it and also a top cabby fan. Would that effect the temperature a bit?
Regards.

re: CPU Overclock List & Discussion Thread

^^
Can you list out all the setting you are using for the OC. QPI voltage is the integrated North Bridge voltage. Usually this does not need to be tweaked only if you are facing really unstable OC.

What TG has mentioned is correct, but would suggest you do this.

1. Reset the CMOS.
2. Set you OC only changing the Mx, FSB, BCLK, vCore and RAM timing. Set the RAM voltage to the EPP setting. See if you can get it stable. If not, then do what TG has mentioned.

Ideally just making speed changes and vcore/ram changes you should be able to get it stable to a certain limit.

But you are facing restart issues, so would suggest to run your system at absolute stock -- till we figure out that problem. No point OC'ing on an unstable system -- what ever the reason may be.

My mistake - I've not noticed properly that prime95 hanged with 1.256V - Run a OCCT 1 hour test with with 1.2625V as it's seems to be stable.

Attaching two more fans will help in reduce temps for sure.

i tried to overclock with that tool but when i overclocked it above 3GHz the computer restarted but some days before i successfully oc proceesor to 3.2 Ghz through BIOS and also checked stability with prime95 and the temp was around 62 at full load and i didn't experienced any problem with the system.i don't know whats the problem with that tool.
BTW that tool shows some maximum point for oc and when i oc it above 3GHz it went above that indicator.i think that could be the problem.i have attached the pic of that tool.thank you

re: CPU Overclock List & Discussion Thread

the processor is not getting enough voltage i guess. cause you mentioned this a few days earlier.

and i don't have any option in bios for changing vcore.BTW my idle vcore is 1.024 and on load 1.184.

and in your signature its written 2.8Ghz @ 1.3volt. so either way, something or some info is missing & i guess that causing your PC to crash.

Yep , when he OCed through bios - bios automatically adjusted the proper vcore for cpu ( though it always a bit too much always from what I've seen ! ) - so his rig was stable.

Most of the E5xxx series cpu can be Oced upto 3 Ghz without raising vcore - so when he oced through that tool upto 3Ghz it was stable but when he oced more than 3 Ghz that tool was not able to provide the enough voltage to the cpu and that's why system got restarted and there's a tiny chance of the app's limitation like he said.

re: CPU Overclock List & Discussion Thread

today i again tried to overclock through bios and oc it to 2.94GHz and ran the stability test of prime95.within 4-5 minutes of stress test prime95 showed some fatal error message in core1(some calculations mis match error) and stopped the test and told there is some hardware problem,again after some time i tried the test and this time also system crashed and restarted and windows reported the problem as "blue screen error" after restart.i don't know whats happening?while some days before i successfully oc it to 3.1 and today it failed for 2.9 and the temp is just fine 57C at full load.here is the link for the details about that 3.1GHz oc.
*www.thinkdigit.com/forum/hardware-q/121070-overclock-list-discussion-thread-4.html
BTW i ran the prime95 test at stock speed of 2.8 for three hours and it ran just fine there was no problem.
please help me guys to find what is the problem.

re: CPU Overclock List & Discussion Thread

Uninstall that OC software ( revert all clock speeds to default prior that ) and try ocing again upto 3.1 Ghz manually from bios setting.

Run a OCCT 1 hour cpu test. I've seen prime95 showing me error but OCCt passed 1 hour test and OC seems to be stable enough.

re: CPU Overclock List & Discussion Thread

prime95 may show error but when i ran the prime95 test again after ten minutes the system restarted and windows showed blue screen error after restart.is this thing also caused by prime95 only?

re: CPU Overclock List & Discussion Thread

if your system rebooted while running prime95 then it's must be some stability issue!

like I said try OCing through bios - set the speed at 3.2 GHz like before and see what happens.

re: CPU Overclock List & Discussion Thread

Ditch prime and OCCT, move on. Use intel burn test.

re: CPU Overclock List & Discussion Thread

^^
IBT is wicked.....!

re: CPU Overclock List & Discussion Thread

@ithehappy

Do you really want to burn your CPU? Why 1.43 for QPI ... reduce it two 1.3X something which you find stable.... In my case for 4GHZ , i Use just 1.27xx for stable....

QPI voltage is the voltage for the memory controller that is on the CPU. You want to keep the memory controller voltage and memory voltage with in .5 volts to prevent damage to the CPU/IMC. If you are not OC the RAMS or have not all slots occupied you don't have to use that much Voltage....

The Sorcerer said:

Well prime and OCCT both use same algorithm to find stability but not with IBT. IBT is different and of course i agree it will stress more than Prime..
Sometimes prime fails even IBT passes.. So running both Prime and IBT respectively is recommended for finding stable system..

Although I prefer LinX of all with problem size of 25000 (more than 4GB only).

re: CPU Overclock List & Discussion Thread

^^
Usually for me Prime95(4x) passes and IBT fails.

re: CPU Overclock List & Discussion Thread

guys i tested it with both prime95 and occt and the test failed.
this are the pics of prime 95 @ 2940MHz and occt @ 3080MHz and windows problem report-

re: CPU Overclock List & Discussion Thread

occt core2 and vcore pics-
guys can the bios upgrade cause any error because at first oc when i successfully oc to 3080MHz my bios version was p1.0 (default) then i updated my bios to p1.1 that is when it was down clocked to normal speed.and at that time the vcore in bios was 1.3v and now it is 1.23v and at that time when i oc it to 3080 the load vcore was 1.234v and now it is 1.18 for 3080.
BTW i ran the occt test for 40min @ 2940MHz and it was successful.

re: CPU Overclock List & Discussion Thread

Okay here are the results after changing the QPI/DRAM Voltage to 1.28125V and keeping the CPU Voltage to 1.2625V, ran OCCT for 45 mins, Prime95 Stress Test was fine, (Max Temp reached- 64-63-61-58) and even ran IBT (changed the stress level to 'Maximum', others were untouched) and plaese also have a look at the first picture, which will show if RAM got OC'ed or not,

and I am also attaching some pics from my BIOS for the other settings which I haven't touched, so please have a look at this.

And Thanks to S_V to inform me about the DRAM Voltage and as to Topgear in advance.
Should I try and decrease the QPI/DRAM Voltage more to find where it gets stable or is 1.28125V OKAY?

I will like some comments about the above done tests. Are they fine or should I have to do some more modifications?

Regards.

re: CPU Overclock List & Discussion Thread

ok guys i got solved the problem. it was intel speed step enabled which was preventing the processor from getting enough power supply, i disabled it now and overclocked to 3107MHz while the full load voltage is 1.24v and passed the occt test of 2h 45m and here are its pics-
and can i overclock it more as still the temperature is 59C?

re: CPU Overclock List & Discussion Thread

when i increase the bus speed the RAM frequency should also increase know?when i increased the bus to 210 from 200 RAM increased to 420MHz and latency was 6-6-6-18 but when i increased bus to 222 RAM decreased to 369MHz and latency to 5-5-5-15.so do there will be any loss in RAM performance?
BTW somewhere i read that as latency decreased the performance increases.is it right?

re: CPU Overclock List & Discussion Thread

^^ Intel chipset always maintains a ratio between cpu speed ( FSB ) and ram speed and that's why your ram speed is increasing/decreasing with the cpu speed ( FSB ). High end mobos have a option to manually select a ratio to fine tune ram speed but many low end mobos don't have such option. They automatically adjust the ratio.

Lower Latency does improve performance though not by a huge margin. Ram frequency plays a major role in speed and it mem performance scalng also depends upon cpu and chipset as well.

As in your case - your temps looks fine - as long as you can keep the cpu core temps under 70C you are good to go but keep in mind the upcoming summer season.

@ ithehappy - your voltages are fine. You can try lowering the qpi voltage a little bit though. Try disabling the speed step - it will help in stabilize the OC more.

re: CPU Overclock List & Discussion Thread

guys i again failed at 3220MHz occt ran for about 20min and system crashed and restarted.isn't that vcore of 1.248 will enough to run at that speed?is there anything else i can do to make it stable?
BTW in bios it shows vcore as 1.304 but it only gives 1.248 why is it so?

What is Speed Step? What does it do? Will try to turn it off and lowering the DRAM Voltage more and response back.
BTW- Are the Temperatures okay? In OCCT it didn't cross 70°C at 100% but it reached 71°C in IBT test.
Thanks and Regards.

It could be lack of NB volt. I used that processor ,hell it OC's very well.. IBT uses more RAM than prime95 that's why it fails in IBT... Try to increase NB volts and see...

I think it's fine since you are not OC manually and just using CPU level up.. I think it need that QPI/DRAM Volts. If every settings changed manually with yours RAMS i think it can run with 1.26/27. But hey, not all hardware OC runs same..

Remeber one thing,, CPU volt and QPI/DRAM Voltage both directly effects CPU temps. so keep them under control.

you are using DRAM voltage setting auto..! Exactly what's the corsair spec volt on DIMMS?

re: CPU Overclock List & Discussion Thread

Little while back ,,Guys I achieved 4GHZ at just 1.19v and passed LinX 20 passes with massive problem size 25000... I had to turn off HT for that volt.... Still the Speed was awesome.... This test i did to enter OC club in famous forum..

Remeber LinX(Same code of IBT but very advanced stress) is the father of all Stress Softwares. Won't agree with me? Well then try it once...

E5xxx series requires manual vcore tunning anything over 3GHz - you are lucky to get 3.1 GHz with your mobo and I think that's the limitation of your mobo.

if you somehow managed to alter your vcore settings manually you will be able to push your cpu speed more.

Are you getting 1.248V under full load while stress testing ? It it's so then it's for vdrop - drop of cpu voltage under full load is called vrop and every cpu does hae this - so there's not much to worry about it.

SpeedStep is a trademark for a series of dynamic frequency scaling technologies (codenamed Geyserville[1] and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation

re: CPU Overclock List & Discussion Thread

k mine is 3150MHz,bus is 225 and multiplier 14 i passed the occt test for 1hr.

Are you getting 1.248V under full load while stress testing ? It it's so then it's for vdrop - drop of cpu voltage under full load is called vrop and every cpu does hae this - so there's not much to worry about it.

actually in bios it is written as 1.304v but while stress test it never went above 1.248 it just fluctuate between 1.248 and 1.23 at full load.that is why i asked why it is not going above that when mobo is providing 1.304?

re: CPU Overclock List & Discussion Thread

@topgear

Sure mate.. Once i reach room from Office.. I will post them later...

Thanks for the comments..

@ithehappy
Yes, i use manual settings always.. I never trust softwares or profiles to do OC becoz they use very high abnormal volts for stable and it's not good for PC life....

@sukesh1090

Take it positive... With your SMPS ,it's really not safe to play with volts like that.. you should consider Branded good SMPS then play with OC... It's just friendly suggestion only...

re: CPU Overclock List & Discussion Thread

Guys I did some testing and got stable OC at VCore- 1.225V and QPI/DRAM- 1.2375V. It passed Prime95 test, though it gave a BSOD first time, but then after restarting I ran it twice and it was OK.

Here are some screenies from IBT (Max Stress, 10 times), OCCT and LinX(Real time, 10 times). Frankly I didn't feel LinX as a good stress testing software, because, it froze in an interval of 15 secs, and I didn't like the CPU stressing method as well. IMO, IBT and OCCT is far better.

Please comment about the results.

Thanks and Regards.

Seems like your mobo has a huge vdrop and some mobos only support up to a certain limit of voltage thus limiting their OC potential.

it would be great if you can post your OC settings in the format mentioned above. Listed your OC.

This is Fecking ****!!I was running my system for a week on 4 GHz...So was going to post it here with all the stress tests...But forgot to disable speedstep...Now that I did that the system isn't booting on anything more than 3.8 GHz....it gets stuck at loading windows...
My voltages are
V core 1.275V
QPI/VTT 1.150V
PLL 1.860V
DRAM 1.6V

does disabling speedstep causes the prob...or c1E??

re: CPU Overclock List & Discussion Thread

Well they should have been from day 1 if OC'ing.

But it seems weird for you. Turn them both on, and show what CPU-Z says.

re: CPU Overclock List & Discussion Thread

@ keviv219 - just revert back to the bios settings using which you got 4GHz stable.

Re: i3 530 with 1666 RAM?

Okay, so I need some little guide to OC my RAM. Please have a look at the below sceenies from BIOS,

1- My DRAM settings is by default 'AUTO'.
*img163.imageshack.us/img163/6020/bios1k.th.jpg

2- I pressed 'Enter', the Menu pops up like this,
*img69.imageshack.us/img69/7666/bios2y.th.jpg

3- Now I selected DDR3- 1600 MHz and this came up,
*img834.imageshack.us/img834/3669/bios3n.th.jpg

4- All other CPU/DRAM settings is 'AUTO', Do I need to change anything here?
*img96.imageshack.us/img96/321/bios4f.th.jpg

5- And this is the settings under DRAM Timing Control,
*img834.imageshack.us/img834/6821/bios5.th.jpg

Now all I want is to run my Memory modules at 1600 MHz but keeping my CPU at Stock Speed, (No OC for CPU).

My RAM is DDR3 Corsair 1600 XMS3 @1.65V.

Thanks in advance.

PS- I've also posted the same in Overclocking section.

Re: i3 530 with 1666 RAM?

Try it without upping the voltage and see if the system is stable.Run some 3D application or something like that to test stability.

Re: i3 530 with 1666 RAM?

You mean upping the QPI/DRAM Voltage or DRAM Bus Voltage? and should I keep it 'Auto' or try to lower it for betterment?

T

Re: i3 530 with 1666 RAM?

It's better not to play with QPI voltage.It might overvolt if you set it on AUTO.The lower the better.
Anything above 1.4 is not recommended AFAIK.Make sure that there's not more than .5v difference between your CPU voltage and QPI/DRAM voltage.
I don't recommend upping the voltages because it will shorten the life of the components.
Try to keep both voltages as low as possible.
My recommendation is not to go above 1.2/3v for QPI/DRAM and 1.6/7 for DIMM voltage.

Re: i3 530 with 1666 RAM?

Okay, I got the idea about QPI/DRAM Voltage but do you mean DRAM Bus Voltage by DIMM Voltage?

T

Re: i3 530 with 1666 RAM?

ya you can increase your DRAM Bus Voltage.same
Note:Again don't go above 1.65v.It can harm your cpu.
Wish you all the best!

Re: i3 530 with 1666 RAM?

Ok, I won't go above 1.65V for sure. What's the Voltage currently @ 1066 of my RAM without OC'ing? Will CPU-Z show it?
Anyway thanks for giving your time.

re: CPU Overclock List & Discussion Thread

Do your RAMS support XMP profile? If it is just select XMP from Ai overclock Tuner to XMP, it will select DRAM speed to 1600 as volt to 1.65 along with SPD Timings came with your Ram . Just make sure to reduce QPI/DRAM to 1.24-1.26 since its just two modules you don't have to use high QPI volt.....

Even if it does not support XMP just select 1600 in DRAM frequency and set QPI volt to 1.25 or less and also DRAM to 1.65v. Set SPD settings in DRAM Timing Control as shown on your RAM which could be 999-24 or 888-24 in the first four settings only.... (ignore the Voltage and CPU damage warning).

Also the Voltage warning is common, so ignore and use it. But just make sure you don't use higher than 1.65v for DRAM bus volt..

T

Re: i3 530 with 1666 RAM?

default voltage is 1.5v I think.AFAIK you will only see the SPD voltage in CPU-Z ie.1.5V.

re: CPU Overclock List & Discussion Thread

re: CPU Overclock List & Discussion Thread

@ithehappy

see, Like i told you ,use XMP profile and set the settings and volts as i mentioned.. you are all set to run them in 1600mhz... you should use 9-9-9-24 and set command rate at 2T.....

currently RAMS are at 1066mhz instead of 1600mhz...

re: CPU Overclock List & Discussion Thread

@S_V, Yep I will do that when I get some free time. BTW- How do you guys know that in what speed the RAM is running? Like as you said mine is running at 1066 MHz, how do you know it? What I see is the DRAM Frequency is 534.3 MHz, so how is it even running at 1066?

re: CPU Overclock List & Discussion Thread

^^
Cannot see any screenies..?

re: CPU Overclock List & Discussion Thread

@ithehappy
DRAM Frequency is 534x2 = 1068 mhz.. That's how you have to do ...

DDR stands for Double Data Rate. DDR3,DDR2 rating is double the actual speed. So ram running 800MHz is running DDR3 1600.

i am going to replace my 10 year old machine..check my signature..is there any possibility of overclocking it? One more thing..i am a complete newbie to OC..guide me to any introductory article..

re: CPU Overclock List & Discussion Thread

dont overclock it.

re: CPU Overclock List & Discussion Thread

So I have done it. Below are the CPU-Z screens and some shots from my BIOS, please have a look at them.

I selected 'XMP' profile, and I have set the QPI/DRAM Voltage to 1.24375V (I set it coz last time when I got stable OC of Processor at 3.7G, the value was 1.24375) and reduced the DRAM Bus Voltage to 1.50V.

Should I decrease them more? Is DRAM Bus Voltage 1.50V OK? or is it still High?

This is after I select 'XMP' Profile,

Other settings in BIOS,

*img543.imageshack.us/img543/4539/photo0198s.th.jpg

and here are the DRAM Timing Control settings, are they Okay?

*img687.imageshack.us/img687/526/photo0199o.th.jpg *img233.imageshack.us/img233/462/photo0200b.th.jpg

and here are the CPU-Z shots after OC'ing,

*img141.imageshack.us/img141/6808/cpuz1l.th.jpg *img842.imageshack.us/img842/1109/cpuz2.th.jpg

Please tell me if I did anything wrong or is there anything need to be done.

and one more question, Can I use more than 1600MHz? say 1800MHz?

and oh, off topic, I was having some Winrar benchmark problem, after OC'ing the RAM I tested it again, and now I am getting scores like 3520 or above, though CPU usage isn't affecting more than 40-42%.

Regards,
Saurav.

Guys need to ask one more question, if I select XMP profile then the CPU Level Up option gets disabled, therefore I won't be able to Overclock to 3.3 or 3.7GHz, now if I select AUTO instead of XMP then CPU Level Up option gets active but at the same time Ai Overclock Tuner gets disabled. Now how can I do Overclocking of both RAM and CPU while putting XMP profile ON? Is it possible? If not then do I need to Manually OC the RAM if I want CPU Level Up to ON? and if yes, should I change the BCLK Frequency and CPU Ratio and others too like it was in XMP profile?

re: CPU Overclock List & Discussion Thread

Ideally do not change any voltage apart from vCore unless you face instability. Keep the memory voltage to the designated profile voltage. Be careful.

Can you please explain? Didn't understand.
Is DRAM Bus Voltage 1.5V good? or should I try and decrease it more?

re: CPU Overclock List & Discussion Thread

Not DRAM Bus, the voltage for the chips. What other voltages you have for memory in your BIOS.

Yes, I won't change anything besides the VCore Voltage and QPI/DRAM Voltage. I got it.
But is 1.5V DRAM Bus fine? or should I decrease it more?

@Topgear.. the idle temp. is 20-21 Degrees.. & the load temp. is around 35-40 degrees.. The temperature of the town is pretty cold too.. around 20 Degrees maximum during day and falls to 4-5 Degrees during night..

Will be adding either Cooler Master Hyper Tx3 or Hyper 212 Plus.. any suggestions?

For some reason, the max. voltage was only 1.392 listed in the BIOS. I had used this board before with 720 BE, and it used to be around 1.5 V.. I think that this voltage thingy depends on the processor..

For RAM best to run it at the designated profile voltage.

I don't think so - I can easily select 1.5V for 630 - actually to reach 3.7 Ghz I need that much volt.

re: CPU Overclock List & Discussion Thread

Do post in the format mentioned on the front page and add some cpu-z screenshots.

BTW, have you tested the OC with some cpu load test app like lynx/prime/OCCT ??

re: CPU Overclock List & Discussion Thread

The 3.5 should work like charm.. I think you can OC more..though not that much as TX3..I doubt

re: CPU Overclock List & Discussion Thread

Actually that 3.5 Ghz was not that stable as I thought.It crashed in prime after some time.Then I increased vcore and memory voltage a bit and now its stable.

Vcore : 1.44 V
memory voltage : 1.61 V
max temp : 57

how is 1.44 V for Athlon II X4 and 1.61 V for Adata value rams ? Are they safe ?

In Adata ddr3 manual, the specified voltage is 1.5V + 0.075V but its running in 1.61 V will it damage the ram ?

If I reduce memory overvoltage to 1.51V in bios, PC will crash during prime.I tried 1.55V and it still crashing after sometime but with 1.61V I can run prime for hours.

I have also one doubt.I am not overclocking memory I reduced the memory multiplier to match with OC.So its in 1066 mode but why does it need more voltage to match with the CPU OC ?

re: CPU Overclock List & Discussion Thread

Hi
I have a doubt to ask.I saw your results with Athlon II X4 630 but I can barely reach 3.5 GHz.Actually I can reach 3.4 Ghz with 243 x 14 and all other settings auto.

But when I put 250 x 14 pc failed to boot then I tried to increase voltage. I had to put memory voltage 1.6v and vcore 1.44.I tried prime 95 and pc is stable in this settings but when i reduce memory voltage it crashes.

I tried 1.51,1.55 and finally 1.61.My rams are Adata and hynix generic ones 1333, their rating is 1.5v

If I run in 1.6v will it damage may rams ? Do we need performance rams those can withstand higher volts to reach heavy OC ?

First of All I'm again telling you to post a cpu-z screenshot of your CPU and memory tab

Now coming to the OC part - not every mobo or cpu will OC equally with same settings even if they are from same series. So your settings may vary.

Upto 1.65V you are safe with DDR3 RAM voltage and you are running them at 1.61V - so nothing to worry about those even the spec is 1.5V only !

If a mem module is running at lower speed then in no way it needs more volts to operate - so I think your mem speed is higher than what you have set. post a pic of cpu-z cpu memory and spd tab - it will make everything clear.

re: CPU Overclock List & Discussion Thread

@topgear
Thanks for your help

I played a little more with all these settings.I reduced memory mode to 800 then I could boot with ram overvoltage 1.51 and it is stable in prime the memory runs in 1000 mhz

*i56.tinypic.com/13yfhwh.jpg

But in 1066 mode memory runs in 1333 and that speed with in specs but it needs 1.6V to be stable

*i52.tinypic.com/10q9s9c.jpg

In 3.4 Ghz I can reduce the vcore below 1.4 and the memory voltage 1.51 and it runs near 1300 Mhz

Among the three above conditions, what would be ideal ?

---------- Post added at 03:23 PM ---------- Previous post was at 01:02 PM ----------

I am glad to say that I have found out the problem of memory overvoltage.In 1066 mode my memory runs at 1333 mhz but in CL7 mode.My rams are generic 1333 CL9 thats why they need more voltage to run in CL7.I changed the Dram timings to CL9 based on SPD's.Now its working fine in 1.51V :smile:

Finally I got a 3.5 ghz stable OC.This is my first ever stable OC; in my old p4 i couldnt even get a 200Mhz OC.Also in this processor with out cooler, the temperatures were never stable.I am goin to post the full details.

re: CPU Overclock List & Discussion Thread

^^ congrats ;-)

see a couple of cpu-z a screen shots can do wonder while OCing to understand everything clearly.

try running OCCT cpu load test for one hour and this should perfectly test the stability of your OC and will give you temp and volt charts under load and idle condition.

Are you using the stock HSF - what's the idle and load temp ??

re: CPU Overclock List & Discussion Thread

I have mentioned in the post that I use Cooler Master Hyper TX3.My Idle temperature is 41C and the maximum temperature in stress test is 58C.But in real life applications like gaming and encoding, it never goes beyond 52C.

re: CPU Overclock List & Discussion Thread

@TG, Hey buddy my stock CPU idle temperature is now 46-44-45-40°C, which was 37-34-37-32°C one month back. The ambient temperature has increased from 23° to 31°C though. My OC'ed temperature in 23°C under full stress was 67-65-63-62°C, so comparing this with idle temperature I guess it will go up to something like, 76-75-72-70°C or maybe more. It's not possible for me to keep the AC on always, so I've planned to add the extra fan to my cooler and another fan at the top of my cabby, will those fans decrease the temp? If you have any other opinions please input it.
In winter that OC'ing was great with all the temps well under 70°C, but now it's summer and that OC'ing seems too high as all the temps going beyond 70° ! So what should I do?

Thanks in advance.

re: CPU Overclock List & Discussion Thread

^^ adding another cpu and case fan might reduce the temp by 3-5C.

if you want to main that 3.7Ghz Oced speed in summer with temps like winter you should better think of water cooling ;-)

overlooked that - correction made.

BTW, for a after market cooler the temp is still high enough - what's your ambient temp ?

re: CPU Overclock List & Discussion Thread

Okay guys I now need some help to OC my GPU. I have a Asus GTX 560, Core clock- 830 MHz. Now I wanna overclock it to 900 MHz to match the performance with the TOP card. But I need to know these,

1- What is the limit of OC of my card? I mean how far can I OC it? Say if I wanna push the Core clock to 950 MHz, is that possible?

2- If I do OC it to say 950 MHz then can I keep the Voltage as stock? or do I have to increase it?

3- If I don't change the Voltage and OC it then will the Temperature remain same or it will get increased?

4- and finally which Software should I use for OCing? Msi Afterburner, Evga Precision or else? Easy yet effective one will get the preferance.

Thanks in advance.

re: CPU Overclock List & Discussion Thread

You all ready SLI'ed it..?

re: CPU Overclock List & Discussion Thread

No sir

re: CPU Overclock List & Discussion Thread

Then the OC you do now, will be different when SLI'ed. The GPUs behave different when connected via the connector. Try to get matching pairs of GPUs as far as you can.

1. You have to find it out ourself - start from 850 hz and Oc by 10 Mhz increment and test stability untill you find the max stable speed.

2. 950 Mhz is possible with stock volt

3. It will increase for sure.

4. I would recommend to use EVGA Precision

re: CPU Overclock List & Discussion Thread

@ithehappy

One thing... you are going to Void Warranty if anything bad goes while running OC .... They can easily tell that you have OC'ed ....

I strongly recommend you to run at stock for now.. Do some benchmarks and after a while do the OC.... Stock is enough for your monitor to run games pretty well...

I am posting the screenshots. Please comment.

re: CPU Overclock List & Discussion Thread

set the Vcore to 1.325V and see if you can run OCCT without any errors at 3.5 Ghz and take the OC to 3.6 Ghz.

For temp monitoring use Realtemp - just leave it running at background while running OCCT cpu load test.

re: CPU Overclock List & Discussion Thread

Skud,

See the settings I used for your CPU.

*www.thinkdigit.com/forum/overclock...clock-list-discussion-thread.html#post1163450

Use RealTEMP for your temperature monitoring. I had it on an Hyper 212 at that time

re: CPU Overclock List & Discussion Thread

@ topgear

Thanks buddy. I can run OCCT successfully @ 3.50GHz with Vcore @ 1.325V. Vantage CPU score shots to 6300. Temperatures were also pretty good. Under load remains mostly at 43-44. Will do some more testings before further OCing. It looks like my RAMs are not doing well, anything above 800Mhz and there are problems. One query, although I have set the memory voltage to 1.80V at BIOS, it keep on increasing while testing. Is this normal?

One question, what's the max Vcore that I can use safely?

re: CPU Overclock List & Discussion Thread

Can you post the RAM SPD settings tab from CPU-Z. You can go till ~1.4, but do it in small increments lower the better.

re: CPU Overclock List & Discussion Thread

Will do once I go back to home.

re: CPU Overclock List & Discussion Thread

Here you go. SPD settings.

re: CPU Overclock List & Discussion Thread

^^
Then you need more vCore for stability. Disable Intel Speed step and C1EST.

re: CPU Overclock List & Discussion Thread

Except Thermal Monitor 2 all other power saving features are off. What next?

re: CPU Overclock List & Discussion Thread

Up the vCore.

It's normal and if you need to push ram speed more you can set mem voltage to 1.9V ( will show something like 1.94V under windows ) and even that is normal.

BTW, run a OCCT 1 hour test and that should give you clear idae about the stability of your OC.

re: CPU Overclock List & Discussion Thread

But I have doubts whether my RAM will be able to handle it.

re: CPU Overclock List & Discussion Thread

It should be able to handle. Right now, your vCore is the key.

re: CPU Overclock List & Discussion Thread

@ SKud - enlisted your OC.

BTW, what's the max speed you want to reach ? looking at your temps I think you might be able to hit ~4 Ghz or even more ;-)

Can you tell me your current FSB/NB/SB voltage ?

@ asingh - Buddy I've asked you before ( 08-01-2011 ) and I've listed your OC but still you have not made a post about your nice OC in here so I'm not able to provide any link to it on the list - it would be great if you can make a post about your OC settings of Q9550 in here. ;-)

re: CPU Overclock List & Discussion Thread

Thanks. Want to get there, currently running @ 3.65 with 1.376V Vcore. But OCCT could not complete. Will post the detailed BIOS settings once I get to the PC.

re: CPU Overclock List & Discussion Thread

^^
I ran it 1.424V or something 24x7 @ 4.00 Ghz. You have standard RAM right. That is the issue. It is going to wall you. I remember I never needed such high vCore for your speeds. This CPU has a damn high Mx--atleast for LGA 775 era.

Also to run tests, just use IBT. It catches errors within 5-10 minutes.

re: CPU Overclock List & Discussion Thread

What's IBT?

re: CPU Overclock List & Discussion Thread

Intel Burn Test.

re: CPU Overclock List & Discussion Thread

OK, probably I already have that. Will check after going back to home.

re: CPU Overclock List & Discussion Thread

Yeah, Intel Burn Test is the best. It also puts most load on the CPU AFAIK. My temps were the highest when running IBT.

ok buddy - I'll wait ;-)

@ SKud - You have to play more with volts and mem speed to reach the mgic spot ( read 4 Ghz ).

For make these change - at your own risk :

CPU Vcore….…[1.425V]
CPU Termination….....: [ 1.300V ]
CPU PLL……: [ 1.600V ]
MCH Core……: [ 1.300V ]

Now disable Fine cpu Ratio control - set cpu multiplier to 10x and CPU Host Frequency (Mhz) 400 Mhz

Set System Memory Multiplier and Memory Frequency correctly so that the ram modules can run only at 800Mhz speed ( that will give you a 1:1 ratio under cpu-z )

Run a OCt 1 hour cpu test and keep an eye on the temps and post back feedback.

re: CPU Overclock List & Discussion Thread

@topgear

OK I'lll try.

re: CPU Overclock List & Discussion Thread

^^
No, do not move the vCore suddenly like that. Never ever do that. You have to find your minimum vCore for the highest frequency at the lowest temperature. ON your own. Raise the vCore in increments. Keep checking. The process takes like 3-4 days and 50 BSODs/restarts.

re: CPU Overclock List & Discussion Thread

what will happen if he up the vcore all of a sudden like that ? I know it's seems like a huge jump and wild guess but it's worth trying and still is in safe limits IMO.

I mean he has proper cooler and a good mobo - if he finds the OC stable at that vcore he should then try reducing the vcore to find what's the lowest possible vcore to get highest possible speed.

re: CPU Overclock List & Discussion Thread

^^
I would not recommend such high increments. Each board behaves in a different manner. Plus his overall configuration is quite different to mine apart from the processor.

Never know when an LGA775 will wall. Also 1.432 is almost the limit for E7400. Would love to reach their slowly..!

re: CPU Overclock List & Discussion Thread

My mobo is just resetting itself at 1.38V. RAM timings were a hell to set provided the meagre 266MHz FSB of the CPU. I am not going any further. Some reviews I have seen where CPU clock drive & PCI express clock drive have been set to 700mV while OCing - may be that would have helped but I fear my CPU would gone kaput. topgear, please update the front page, that 3.6GHz is my final. Thanks to you and asingh to guide me thru my 1st OC!

re: CPU Overclock List & Discussion Thread

Leave the vCore at the stable position, I guess 1.36 for you. Increase the NB voltage a bit. Try.

re: CPU Overclock List & Discussion Thread

asingh said:

NB voltage is MCH core voltage I guess.

re: CPU Overclock List & Discussion Thread

^^
Yes, correct.

re: CPU Overclock List & Discussion Thread

It was already 1.26V from base of 1.10V. OK, will try once, just to be sure.

ok buddy - got your point ;-)

@ Skud - your mobo was resetting at 1.38V vcore. What FSB you set at that speed ??

re: CPU Overclock List & Discussion Thread

348 MHz, 5 MHz increment from previous.

re: CPU Overclock List & Discussion Thread

Oced to 4.8GHz, ran small FFTs test. So far good but might not be stable for longer run.

Hitting beyond 4.9GHz require more than 1.43 Vcore, not worth the MHz increase.

re: CPU Overclock List & Discussion Thread

Some really nice readings: CPU @ 0, Fans over 50000rpm. :lol:

Just guessing [TRIAL]= how many rpms?? :))

On a serious note: nice OC.

re: CPU Overclock List & Discussion Thread

@ Faun

Great numbers man! :doublethumb:

Keep up the good work...

BTW u might like to use HWInfo64 its better for reporting and works great with ASUS Z68 boards

Trial version puts random [Trial] tags on startup. And those readings are :razz:

I was using HMonPro for individual cores temps. Close enough as confirmed from ASUS sensor utility.

Ran OCCT but halfway power went off. Come night, will start again.

re: CPU Overclock List & Discussion Thread

^^ nice overclock, the last breed of CPUs where OCing was still fun.

Ever since SB came, it's either piece of cake 'K' series overclocking CPUs, or NOTHING at all.

INTEL killed the fun of overclocking a mid-range CPU to surpass a high end one, period.

@ everybody, please, post THUMBNAILS. Thank you.

re: CPU Overclock List & Discussion Thread

Nice OC, Mithun.

re: CPU Overclock List & Discussion Thread

Thank u guys i still think i can go up to 4.5 on adding one more fan in push pull in my ECO
and by getting a better RAM the ram i am currently using is ADATA value RAM thinking of adding GSKILL Ripjaws 1600 what do u think shoud i go for Gskill or Corsair

re: CPU Overclock List & Discussion Thread

^^ if you can keep the temps under 70c under load then set the bios vcore to 1.35v and push the cpu to 4.5ghz though i've not seen any 530 hitting beyond 4.3ghz under air cooling.

BTW, is that's a water cooler you have for the cpu - care to share some pics ;-)

BSOD: After OC-ing, the RAM's are configured as Dual Channel Memory & How to achieve DRAM Freq - 1600MHz...

Any help will be highly appreciated.

re: CPU Overclock List & Discussion Thread

Try increasing the DRAM volt a little 1.6V and see
BTW what memory u r using u can also underclock ur RAM to 1333/1066 with tighter timings wont make much of a difference in performance see the memory speeds & timings in cpuz for ur guide

BTW u call this outdated still it will give a lot of systems a run for money with 570
i personally feel 1366 platform is still the best and u see new MB released on this even now it has been around for a long time

re: CPU Overclock List & Discussion Thread

The DRAM Voltage is already set to 1.64v. I have XMS3's. I will check out other speeds today...

re: CPU Overclock List & Discussion Thread

The XMS modules are always over volted than normal i had XMS2 modules which were rated at 2.1V Normal check the real specifications of the Modules u have those will help

re: CPU Overclock List & Discussion Thread

I had successfully OCed my Athlon II X4 to 3.5GHz but I dont see a noticable difference any games I play.Even with a 25% OC no much gain in games.The only advantage is the faster encoding times.Is it the lack of L3 affects gaming or the clock speeds has nothing to do over a particular range? Or the architecture matters most?

re: CPU Overclock List & Discussion Thread

Bro Games use the GPU so the effect of OC is nominal but encoding is competely handled by CPU so u get performance benefit there in games it will matter if ur cpu is a bottleneck to a very powerful GPU in ur case it is not please correct me if i am wrong

Overclocked my Phenom 550 from 3.1 to 3.3 Ghz. My motherboard is crap, and does not allow further overclocking.

In Bioshock 2 with the stock cpu speed I got 30 FPS but when I oced the CPU to 3.7 Ghz the FPS jumped to 90 - so unreal engine 3.0 scales well with cpu OC ;-)

re: CPU Overclock List & Discussion Thread

@S_v

The overclock is awesome. The benchmarks are looking great

especially 3d Mark Vantage

a small question=
Is there a way to make 3d mark vantage below the lowest supported resolution of 1280x1024? My monitor max resolution is below that

re: CPU Overclock List & Discussion Thread

@thetechfreak....

Thanks mate....
Regarding your question...
You can change the resolution below that Default if you are not running Free version. Are you?

if you change the resolution you are not running the same benchmark and so your score won't accurately compare against other PC's.

hi there.....
am achieving for benchmark stability now...hence no IBT

although IBT @ 4.5GHZ would be stable....
here are some 2D benchmark wid tem screenies...the first runs cooler than others...
*i.imgur.com/ZlvkC.jpg
PLZ note...this aint prime stable as i am not tryin for it...also PRIME95 is not needed in real world scenario coz no software stresses the chip to 100% all the time.
On stock HSF it hold well upto 3.81...not more than that....

re: CPU Overclock List & Discussion Thread

@Sumon...

you are right, that Prime95 or any other similar does stresses the chip 100% unlike real world scenario.....

But you are forgetting one thing.... using OC'ed system which is not stable will shorten the product life soon than using High Volt stable OC..... There is a reason for BSOD when OC Fails.. It's like undervolt and Overvolt in Electronics which would damage them eventually.

re: CPU Overclock List & Discussion Thread

^^i know.....i dont intend to use 5GHZ as 24/7...and when it comes to benchmarking...all i care about is 3d stability...tats all...
one should not OC if he is worried about damaging electronics...but thats only my opinion...people may differ....

re: CPU Overclock List & Discussion Thread

i have got my phenom 955 upto 3.4ghz stable by raising the mulltiplier through asus tubov evo, but do to that i have have to be on 24x7 OC and disable C&Q

now in my bios i have CPU Level Up option which raises the the cpu and ram freq. to a higher model cpu like the 965/975
this option is perfect for me as it dosent require 24x7 ocing

but the problem is that i am running corsair 1333mhz value ram (with no heat sinks) and with 3.4ghz the bios raises it to 1420mhz
is it safe for a value ram to run at ~90mhz more??

so i pressed the memok butoon 2-3 times and was able to boot with a message that said oc failed or something, then again when i rebooted same problem
so i had to reset the bios

how is it that system ran perfectly with above oced setting one day and now simply refuses to boot with those??

i can run it successfully all day with multiple reboots but when i switch off the system at night and then power on in the morning it fails to boot giving 1 long and 3 short beeps
the only sol. then is bios reset

i guess its a ram problem
the cpu level up increases the ram freq. to 1420mhz with 3.4 ghz
normally my ram runs at 1333mhz

this is happening for past 3 days

@Vishal try setting the memory frequency @1066 with tighter timings & use 1.6V during OC

re: CPU Overclock List & Discussion Thread

thanks, runnin ram @1140
no problems now

regarding timings, my defaults are 9-9-9-24 at 1T, what do you suggest??

re: CPU Overclock List & Discussion Thread

What's the default speed and Voltage?

EDIT: I got it..... I saw you Sig But Still What is the default Volt.?

you can try using lower timings mentioned in your SPD profile.. To see your RAM SPD profile use CPU-Z and check the timings in 1066... and try to use them... Try to use 8-9-8-24 with default volt.. Don't increase Volt unless using above 1333 or Very lower Tight Timings....

re: CPU Overclock List & Discussion Thread

@vishal can u post a CPUZ SS of the SPD

re: CPU Overclock List & Discussion Thread

@S_V

default volt is 1.3

@mithun
here are the screens

re: CPU Overclock List & Discussion Thread

@Vishal

Your default is 1.5 according to SPD not 1.3

Anyway... Try those Timings in SPD profile and do memtest to check their stability. Also Those are Corsair Value Select RAMs and OC is not really good Choice...

re: CPU Overclock List & Discussion Thread

allright...try 8-8-8-24 on those sticks @ 1333mhz
@S_V
those sticks are pretty robust for value rams

re: CPU Overclock List & Discussion Thread

UPDATE-
RUNNING ON 8-8-8-24 @ 1T STABLE

@S_V
i thought you were asking cpu volts

@sumon
i cant run 1333mhz stable, hence running 1140

will try both 8-9-8-24 & 8-8-8-24 settings

Though I dont need but is it possible to OC further on air cooling? Also, I want to run RAM at 1600mhz.
As said, I dont know basics of OCing, can someone at TDF guide me in simplified way?

Where do you live? Those temps look awesome to me. You can push even further safely I think. And although I don't much about OCing AMD CPUs, I think CnQ need to be disabled for stable clocks.

post a couple of cpu-z screenshot of cpu, memory and spd tab

you're fine upto 65C under load - so you can OC even further.

To run your memory modules around 1600 Mhz set the FSB-DRAM Ratio to - 1:3 ;-)

re: CPU Overclock List & Discussion Thread

I wanted to clarify something as i am noob in overclocking.

I got my sig rig and i overclocked it. Not manually just automatically that my mobo utility provided. And i can see when i stress my cpu it went to 4.2 ghz. So i call it stable overclocked or something?

re: CPU Overclock List & Discussion Thread

i think u have enabled TPU feature in the mb which auto oced it 5ghz the turbo boost freq of ur processor is 3.7 so it is showing 4.2 on full load
oc'ing ur processor manually is also easy since it has an unlocked multiplier & u have an aftermarket cooler but do keep an eye on temps during load use core temp give it small increments & proceed

re: CPU Overclock List & Discussion Thread

Run Intel Burn Test , Linx or Prime95 ... While running any of the software make sure you keep an eye on Temps also.. Even OC is stable ,Too high Temps will lead you to BSOD....

But Learn Manual OC from Internet for that processor and the main advantage of Manual OC is that we can maintain LOW volts.. so Temps will be in control...

SandyBride Overclock is very easy compared to Old Generation Processors.....

re: CPU Overclock List & Discussion Thread

yes i used tpu so i can say it's overclocked or stable 4.2ghz is called overclocked? i tried that prime software n i got around 60'C temp!

re: CPU Overclock List & Discussion Thread

^^ looks like the 4.2Ghz OC is stable enough - go on next phase and OC the cpu to 4.5 Ghz - the cooler will handle it really well and if possible attach a second fan on the CM Hyper 212+ ;-)

re: CPU Overclock List & Discussion Thread

@mithun_mrg

That Overclocking is awesome considering that processor...
SO what's the Cooling solution you are using?

Also you need to put little bigger screen shots for better view...

re: CPU Overclock List & Discussion Thread

Thanks s_v i am using coolit eco R120(single fan)
~~will edit the post with bigger pics~~done

re: CPU Overclock List & Discussion Thread

can u run Cinebench11.5?
Let me know the score please.....

re: CPU Overclock List & Discussion Thread

@ mithun_mrg - nice OC and you OC is now listed ;-)

re: CPU Overclock List & Discussion Thread

Thanks Topgear
@s_v here is the cinebench result crashed twice at 1.376V then i cranked it up to 1.416 memory at 1.6 then is ran max temp was registered at 70C will try to hit 4.8 this weekend with that voltage if i can manage another fan in push pull config

re: CPU Overclock List & Discussion Thread

@mithun_mrg: awesome overclocking with 530. (specially considering your processor)

re: CPU Overclock List & Discussion Thread

@ mithun_mrg - 70c is hot enough - if you want to get 300Mhz more speed then the heat generation will be more and it might need additional vcore - so before pushing the cpu speed/vcore any further take care of the cooling part.

Thanks mate... It's the reason why I asked you to run CineBench 11.5 ..It's very demanding and good choice to see your Processor Speed...

yes thats why i will do that after adding another fan to the cpucooler

ur welcome mate it really is

re: CPU Overclock List & Discussion Thread

I have a question...I have Hyper 212 plus..and I did buy 2 CM Silent Green LED fans..but when I am using those in Push pull config, the RPM of both fans are 500 apart...The intake one runs at 1800 while the push one is running at 1200-1300...And I think it's not right..as it sort of creates a lot of air around the heatsinks..so is it normal or am I missing something...

Another thing..earlier my temp at idle was used to be 30 to 35C when I OC'ed it to 3.8-4.0 GHz...and now even at 3.2 it idles at 38C...what could be the issue...

re: CPU Overclock List & Discussion Thread

^^
That much RPM delta should not make a world of difference. The thermal is a direct function of the vCore being pushed in. Did you increase the vCore.

re: CPU Overclock List & Discussion Thread

I tried to..and it didn't boot up..I set it to 1.3V...
I was using OC'ed setup for almost a year now, it was all cool and good...and did a reassembly recently, and the temp increased after that...I think I have to check if the cooler is fitted properly..maybe it's too tight..

So u suggest I put the other fan back??

1 more thing with or without the other fan..the temps are the same..no diff at all..

The vcore is set to auto...and I have lowered the clocks to 3.2 now

re: CPU Overclock List & Discussion Thread

For the fan RPM just disable the Smart/Automatic fan controll in bios options and let the fans run @ 100% speed.

If mounted properly a push+pull setup should reduce temp rather using a single fan.

Most of the chances the Cooler is not properly mounted on the top of the cpu or it could be the TiM which is making the temp difference - let the Tim some time to settle.

or else you can try some good Tim ( clean the the old Tim from cpu and heatsink ) and see if you can get any temp difference.

re: CPU Overclock List & Discussion Thread

^^exactly @Reaper_vivek get rid of the 3pin to 4 pin adapter supplied with the fans & disable smartfan rpm problem will be solved also dissemble the fan & clean the tim & reapply it & see

re: CPU Overclock List & Discussion Thread

I did the TiM part carefully..I use an aftermarket one from Cooler master..it cost me 500 bucks..forgot the name :s

Anyways, I'll disable smart fan now and see if there is a diff..
Is the fan speed issue because one is connected to the CPU fan adapter while the other to normal one?
As for the heat prob...I think it's the Cooler setup..maybe I used too much pressure in tightening the screws..as I kept pushing them..maybe I need to loosen them up a bit..

I am planning to go beyond my previous clock of 4.1GHz but am vary of the heat issue...maybe after my exams, I'll spend some time tinkering..

re: CPU Overclock List & Discussion Thread

Try not to use auto vCore. It 'may' push in too much. Keep lowering it, till you hit instability.

re: CPU Overclock List & Discussion Thread

I found this pic of my 4GHz OC on my cooler...it was taken way back in feb...and it was my first OC(yay

)...and that too at 1.28V Vcore..pretty sweet..

re: CPU Overclock List & Discussion Thread

^^ just one word "awesome"

re: CPU Overclock List & Discussion Thread

@ S_V, try pushing for higher memory(6144) in LinX, use the latest linpack binaries, else you can't get a proper Gflops comparison, my system at stock(3.5GHz)*

*i.imgur.com/Ld2Of.png

*i.imgur.com/PSh2h.png

* I'm considering Gflops rating depend on available memory amount, if not then your Gflop rating is too low.

re: CPU Overclock List & Discussion Thread

@tkin...

I know my Glops is less ... I am not running LinX with AVX instruction sets. So that's one of the reason I am getting low Glops... It's not exactly the amount of RAM you have...

EDIT : Please check the following tests i have done, with your Processor also and let me know the scores... I saw immense performance in all applications as well as games in my PC..

@tkin...

here it is... with LINX with AVX sets... I ran with Stock for now....

*img.photobucket.com/albums/v358/sunil_9/Benchmarks/Benchmarks/LinX_AVX.jpg

re: CPU Overclock List & Discussion Thread

Its ok, and you're not running on stock, cause on stock with all 4 cores engaged sandy is supposed to oc to 3.5Ghz NOT 3.8GHz. Here's Sandy Turbo:

Turbo can provide a 400Mhz speed boost in single-threaded workloads, 300Mhz in dual-threaded workloads, 200Mhz in triple-threaded workloads, and 100Mhz in applications that utilize four threads or more.

PS: H100 is nice cooler btw.

re: CPU Overclock List & Discussion Thread

yeah tkin... I meant stock in the sense default settings in the Bios and yes turbo is up when load... that's expected all the time....

able to POST at 4.2G with i5 750 on consider urself "LUCKY"!

re: CPU Overclock List & Discussion Thread

Errr..it is me who is doing it..I hit 65 at 4GHz..at 4.2 it isn't stable..I could listen to few songs...but as soon as I tried Prime 95 or OCCT for more than 2 mins I get a BSOD...
I can reach 4.4 on mine...but I need to do it from scratch..I never carefully played with the voltages..I just increased and decreased it as my liking and intuition..

I will try to get the PC stable at 4.2..and then push for 4.4 or 4.5..anything above that is a too far-fetched for my cooler..

re install the os with 1gb ram xp is recommended

re: CPU Overclock List & Discussion Thread

^^No, i can't install xp in this laptop.It cannot recognizes XP os cd.About the problem i just changed the Dynamic CPU frequency mode from dynamic to always low.Now the vcore is 0.950 v and temperature is didn't crosses above 65 degree Celsius.Now its stable to do daily works.
But to lowered the temperature more i think i have to clean the heatsink of the cpu.

re: CPU Overclock List & Discussion Thread

**N00b**

On my prev Intel DG31 mobo I had a core speed of 2600 MHz with Multiplier X 13 and Bus Speed 200 MHz [FIXED] and Rated FSB of 800 MHz .

I got a new Gigabyte G41MT-S2 mobo and values are 200X16 = 2600 at full load and with less load they switch to 200X6 = 1200. Is it due to some option in BIOS set to auto/default ?

In BIOS there's an option M.I.T which lets you tweak values - I haven't changed anything yet as I want to be sure of different terms used in Gigabyte boards.

What should be my next step ?

PS: This's my first OC and am trying to familiarize with the process any help is highly appreciated.

though the auto vcore is a bit too high the load vcore is good enough.

the difference between the auto vcore and load vcore indicates some huge vdrop - are you using the latest bios version ? Try manually setting the vcore if possible but as long as the test and real world cpu hungry apps are stable no need to worry too much.

TP nice!!

megamind thats excellent oc! when are you going to submit that super pi to hwbot? :))

I get Bsod on 4.5ghz @ vcore 1.32 not while prime testing but while surfing web or watching so i increased it to 1.34v. So you guyz think it's ok voltage for that?

@kapil, every 2500k chip is diff. so u can't compare your OC & volt. with another 2500k...

So inc. the volt in 0.005 steps.. Until u get it stable..

will this qualify?

didn't knew about the new rule...

^^ congrats for being the first BullDozer OCer of this the forum and that 5 Ghz OC using Air cooling is really awesome ;-)

why do overclocking fails if i relax or tighten timings during oc?
i can only adjust ram speed. if i change timings it fails.

^^change the command rate to 2T from 1T

It depends.... Sometimes for Running Tight Timings needs little extra volts for DRAM volts and for running Loose or Tight timings in Higher FSB needs Voltage too....

mithun_mrg said:

You can try this option too...

mithun_mrg said:

tried, even this gives a oc fail error.

S_V said:

You can try this option too...

even in loose timing, like i now have 7-7-7-19 at 1289mhz at 3.5ghz at 1.5v vcore.
if i do 9-9-9-24, fail. however if i change memory speed, it is fine! timings tighten as memory speed decreases, but i cant manually change them during oc.
tried higher memory voltage for tighter timings but didnt work.

i am keeping FSB round about same.

shall i try with different BIOS? (currently latest)

You are using 6GB right? 3x 2GB?
If it is try to remove one 2GB and try with 4GB... What's your default Timings and Speed of your RAM and Stock VOlts.. How much did u increased your memory Voltage?

I really like to see your BIOS images in OC section. Becoz there could be another option to maintain balance other than Memory and CPU Voltage.... Also what's the FSB and DRAM Ratio currently it is?

i use 2GB+4GB stick.
tried removing and changing timings but didnt work.

1st module - G.Skill F3-10600CL9S-2GBNT
2nd module - G.Skill F3-12800CL9S-4GBXL

both of them are rated 1.5v but mobo sets 1.6v. i tried 1.65v too but didnt work.

here you go -

hah looks like you are having the same problem like me.even i failed to tighten the timings of my vangeance 4GB ram by increasing the dram volt to 1.65 but pc boots but there won't be any display.then i have to open my cabby and clear the CMOS then it will work?why is it so guys?btw my mobo has dual BIOS.

@Sukesh1090...

Its really Bad that you can't able to OC Vengeance Ram.. Actually Vengeance are quite Extra-Ordinary to OC... Example....with just 1.62v and loose Timings I can able to Achieve Stable 2133MHZ OC....

@Singh

Try to Increase North Bridge Volt as you know it is related between Memory and Processor.. Also You have two different RAMs and unlikely to support OC . It's really Luck...

Try to Disable Bank Interleaving and see How it goes...(Only If you are using Both 2 and 4GB Rams).

^^
any suggestions with overclocking it.i am using 4GB single stick.btw did you see any performance improvement with increase in ram speed?

^^ It depends on the platform and apps you will use ;-)

^^
I use BIOS bro.jas has already posted its screenshot.mine is also same.

^^ I think there's some sort of misunderstanding from my end ;-)

I thought you were asking whether performance improves with lower latency or higher memory speed.

BTW, AMD platform such as Phenom II responds better to higher mem speed more so try OCing using the FSB not only raising the multi - Increase in FSb will increase mem speed and latency too but use some benchmark apps and you will see improvement in performance as well ;-)

^^
k will try today evening when i get back from college.now i got practical exam in morning thats why i woke up early :mrgreen:

or else i wake up at 6:30.

I really can't suggest blindly without looking into complete BIOS of the Mobo. I am really concerned about your Hardware, If anything wrongly done with Volts. It might Burn your Hardware especially If we don't know what we are doing.

Regarding Performance , I saw difference compared to stock during Benchmarks and RAM dependent apps. But in overall you won't find much difference except in applications starting and closing. After all, it's 2133 mhz and compared to stock 1600mhz it's quite an BUMP in performance. You won't find much difference between 1333-1866mhz except in RAM applications.

I can suggest you one Thing is you can stop worrying about OC'ing your RAM unlike Processor it's not Much performance gain. IMHO. :wink:

Indeed... When Overclocking CPU needs extra Power and PSU could able to Produce that Power Consistently. Power Factor and Ripple does effect while Overclocking. If PSU couldn't cope up with Power Demand from Components while OVerclocking the system Restarts or ends up with Damaged Components.

Referring to your PSU.. yours is Super Fine to OC and Don't need to have second Thoughts.

In OC concept, OC depends on your Proccy Chip, Mobo and RAM and ofcourse your choice of settings.

So PSU does matter in Overclocking too. Remember Gold,Sliver etc Certifications are for just for Quality and Efficiency but not for OC.

9400m MacBook EXTREME Overclocking Guide. [C/GPU]

Guys today I tried to unlock my AMD Phenom X4 960T to get its 2 hidden cores working, but I failed to do so. What I did was -

>Core Unlocker to Enabled
>CPU Core Control to Manual
>Rebooted into BIOS
>Enabled the two hidden cores from BIOS
>Rebooted
>Windows Logo appears but it doesn't boot.
>Booted again in BIOS
>Disabled last Core#5
>Rebooted again, but still didn't boot.

Does this mean the cores are not stable? When I disable the core unlock feature, it boots fine.

^^ The unlocked cores must be unstable/faulty or try bumping up the cpu vcore and cpu-nb volt.

BTW, did you enabled unleashing mode / EC firmware to Hybrid state ?

^^ ok .. thanks ;-)

I have a cool (and old) game, Virtua Fighter 2 (Virtua Fighter 2 - GameSpot.com). After I overclocked my system (bootcamp) it runs very fast, like too fast to be played. This did not happen instantly, i.e., a few weeks after the overclock. So is the only way to run it again at normal frame rate is to de-overclock my system?? Or is there any other solution?

if the game is really running fast due to OCing then why is the 1 week delay to gain the performance boost - Oced performance boost ( specially cpu ) in any apps and games can be noticed immediately - I think the performance boost you got due to driver update ( specially gpu ) and make sure the vsync option in turned on in games gfx option r some game has the option for limit the FPS at 30/60 soo that you don't feel like the game is running too fast ;-)

No, there were no driver updates (not to my knowledge anyways). And not just the gameplay, even the menu and everything too runs super-fast. And there is no FPS capping option in the game....

then check and enable the vsync option.

Well, Today overclocked for first time. Not much coz i don't have aftermarket cooler right now. But planning for it.

C2D E7500 2.93 GHZ to 3.20 GHZ.

Did 30 min stress test with prime95 , played Gta iv and witcher 2, everything seems to be stable.

Didn't know much about overclocking , started learning today morning by google. What i did is to disable EIST and then Increased BUS SPEED to 286.

Overclocked to 4Ghz. Running 24X7 totally stable. Gonna max out at 4.2GHz later..
Will be OCing RAM soon.

Overclocking for the first time..

Some guide for memory OCing please?

^^ your mem modules has XMP profile - use that first.

@ Alok - post your pc config - ie PSU, mobo and ram modules type and speed - most important.

Sad to hear that it can not be overclocked from BIOS. Will it be worth to try overclocking using OS based application ?

Mmm guys, know any good OC guide for beginners?

I went through *www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/1 for an introduction to Overclocking. Are there any other sites for step by step guide for i5 2500K.

I want to read up on OC-ing before deciding whether to go for a build around i5 2400 or i5 2500K (which will be more expensive).

I have Corsair TX650W and a Sapphire HD 6850 1GB - will this psu suffice?

The PSU is enough.

@ sharang.d - temps are OK - aim for 4.5 Ghz - keep an eye on temps - don't let it cross over 85c under prime95 test but if it's a 24*7 then 80c should be the limit temp for prime95 test.

@ Alok - first try to reach 3.6 Ghz with the mobo you have - for cooler look for Cm Hyper TX3 at ~1.35k.

@ Rishi - there's no siftware available to oc the cpu using the mobo you have.

@topgear ok, now what i saw that when i set bus speed above 285 , system won't start(not even post).I googled and got idea to set my ram to 667 , now i can go further :-D

but tell me , is this going to slow ram?

Currently at 3.41 GHZ :clap2:

One more question, before overclocking my fsb:ram was 2:3 but now its at 4:5. Is it ok ?

It seems now i can push cpu frequency "very far" after reducing ram clock. But i won't go above 3.4 ghz coz i don't have aftermarket cooler.

topgear said:

i tried at 3.69 GHz(333 bus speed) and system started as it should. Idle temp were 37-40 'c. But i reverted back coz i don't want trouble. :-|

and i "didn't" touched vcore voltage yet and don't want since i heard it generates more heat.

I'm fine with 4.2 for now

Would do more but it's not required

I wana do some RAM overclocking but no one tells me how :-x

not much - the incresed CPu speed and FSB will compensate it ;-)

if you go above 3.4 Ghz now you need to do lot more stability testing using prime95 small FFT test at-least for an hour but before doing any such thing nte that you need a after market cooler and your mobo has no VRM region heatsink - so it's kinda risky. The best possible way to remain within safe zone is to find the max possible stable clock with default cpu vcore ;-)

prime95 temps looks a little higher but this may be due to stock cooler or some issue with Realtemp - use hwinfo for load cpu temp.

gaming temps are good but as I said use hwinfo and play BFBC2 - this will stress test your cpu and the OC too.

yes i'll do everything to stay on default vcore.
I'm planning for Coolermaster tx3 as you suggested, its only 1.4k

.
what vrm ? Its for gpu cooling? Please explain.

topgear said:

yes it seems due to stock cooler. Ok will test with hwinfo.

So what i understood so far that increasing bus speed won't generate that much heat but increasing vcore a little will significantly affect it. Ok ! I will try to get most stable clock without increasing vcore.

And i disabled C1E and EIST, fine? (i think these are just for power saving)

Thanks again for your help Topgear. I'm learning very fast. :-D

^ Staying at default Vcore is good but I dont think you're going to have any problems if you go a little bit over it.... I could get to a stable 3.1GHz(from 2.7GHz) on a 65nm AMD Dual Core using Asus 780G and VRM's were not compromised. Anyways on stock heatsink u shud be able to do anything between 3.5 & 3.8Ghz using that proc... depending on how much are you pushing and the cpu ofcourse...

Only reason to stick to default Vcore is that you have an MSI motherboard.

VRM - They provide power to CPU.... GPU have their own VRMs...

yeah , since i don't have aftermarket cooler ; only reason for not increasing vcore . Coz it leads to more heat.

Btw my cpu is 45nm.

^^7500 is a great cpu and with proper mobo and good cooling they are known to go over 4 Ghz easily ;-)

AMD and Intel cpus have differnt volt tolerance level - AMD cpus can work with 1.55V with air cooling but for the Intel C2D cpus you should not go over 1.4v though more is possible using air cooling ( but do these at your own risk )

Here's a pic of cpu VRMs ( the little black boxes - 6 on pics )

*www.ixbt.com/mainboard/msi/dka790gx/vrm.jpg

here 's with passive cooling ie heatsink :

*techreport.com/r.x/p67-mobos/asus-socket.jpg

how far a cpu can be Oced depends on the cpu and the mobo's VRM quality, quantity and if the VRMs have proper cooling or not and not to mention a good PSU and cpu cooler.

System specs are in signature.
4.2 GHz OC with -.050 offset and LLC to auto. Din't touch any other voltages. Just changed the phase control and duty cycle settings to extreme. Vcore under full load with prime95 stays at 1.230v. At idle it drops down to around .9v . Do I need to keep an eye on individual cores VID voltage also or just the Vcore? I am using HWiNFO to monitor.

Just done IBT high stress 20 cycles test. No issues till now. Prime95 Blend test running at the moment. If I am stable for lets say 3-4 hours then I will aim for 4.3. I just want to reach as high as possible without manually messing up with voltages.

^You don't need to change voltage for such a low OC anyway.

^^ I had to change it coz on everything to auto vcore was going around 1.290-1.3v which i thought was way too high for this kind of OC so played around with offset settings..

I have the same 4.2 OC and I get 1.3 VCore as well on everything auto. I don't think auto settings would let it go to the higher side. Let's wait for someone else's input though

^^

I don't think auto settings would let it go to the higher side

if you are talking about the cpu speed well you can go higher even with auto setting - the vcore will be increased with cpu speed increment ( upto a limit depends on mobo model and bios though ) so it's better to play manually with cpu vcore setting to find the optimum cpu vcore for a specific cpu speed.

This is what was happening with me. 1.3v for 4.2 was way too high IMO. So I played with offset settings. Now when my CPU is under 100 percent load LLC kicks in and vcore stays around 1.224 and when on idle its around .912. Although I think because of this Idle vcore my system is showing symptoms of instability. There is no problem in 100% load condition but when you are doing menial tasks then this can trigger a crash. no BSODs yet but I think its gonna happen soon. I am gonna try 1.23 manual vcore and LLC to auto and see what happens.

I've been running 4.2ghz for a month now with auto vcore. No BSODs.
I trust my asus

try 1.26V with llc extreme/high...

sharang.d said:

I trust my asus

at 4.2 with everything on auto BSOD was never a problem. The problem was high vcore when it wasnt required for such low OC. Thats why i changed vcore manually. When I tried -.050 offset with everything else on auto stress testing went fine bt menial tasks like browsing etc were showing symptoms of a crash(mouse starts to lag etc etc. No BSOD yet). So i have manually changed vcore to 1.23 and LLC to auto. Its stable till now. Blend test has been running for 2 hrs and no errors yet. IBT high stress test also went fine. Lets see what happens. If this goes fine then i may try for higher clocks(4.4-4.5)

^By BSOD i meant including all other kinds of problems. I mean even when CPU is on full load @ 4.2 + auto vcore I don't get any of the symptoms you mentioned.. so I didn't manually change vcore.
Maybe it has got something to do with the rest of our hardware?

^^ possibly yes plus different chips behave differently. Whats your vcore under full load? But i have to agree with you on one point that asus really has optimised all the auto settings brilliantly.

^1.334V max when running prime95

^^ thats pretty high I think for 4.2 OC. You can goto 4.4-4.5 with that much vcore(maybe even more if you have a good chip). Same was happening with me. My vcore on everything on auto was going around 1.3v thats why I set it manually and its stable. helped me to get my temps down as well. Now with prime95 running vcore stays at 1.2 max.

^What max CPU temp are you gettin with ur setup during prime95 Blend test?

^^ Hottest core=58-59
coolest core=52(core 0 or 1st core)
core package= 57-58
cpu tcase temp= 46
Ambient temperature here is 28-30
These temps are after 1.5 hrs of prime95 blend test.
Add 5-8 degrees more for IBT testing.

^Those are really good temps for 4.2
What's your ambient temp?

^^ As mentioned above 28-30 degrees. Whats your core temps at max load? Also mention the ambient temperature please.

30C ambient
65C Max temp on prime95
I should try lowering Vcore like you did to get lower temp but the thing is that CPU is never on full load so im not really worried about the temp @ 4.2GHz
What's your idle temp?

^If 65C is the core temp and not the cpu tcase temp then I think you don't need to do anything but yes lowering vcore will surely help with temps.

Well idle temps are whole other story. 2 cores stay at 42 while the other two stay around 33-35. At first i thought i have made some mistake in either installing HSF or applying TIM. So I redid all of that 3 times and still the same result. But since load temps were perfectly fine so I don't care about idle temps much. Cpu Tcase idle temp is around 32 if ambient is 26-28 and 34-35 if ambient is around 28-30.

I just wanted to know performance of your Cooler so asked about your CPU idle temp

Also where to view CPU tcase temp? The one we see in ASUS Suite?

My idle never goes beyond 40

Hovers around 35 most of the time..

yes thats the one or the one you see in HWiNFO under nuvoton section. Will try 4.5 tomorrow then it will be a real test for this cooler as vcore will surely go beyond 1.3

Okay thanks.
Ran prime95 Blend test for 36mins.
Max values recorded:
Cpu tcase -> 51C
Max core -> 71C
Vcore -> 1.344

Are these values okay?

Everything is ok as long as its below 75c, period. And 80 would be danger line, 85 is max limit for insane ocs.

For that vcore and hyper 212 evo I think you are fine there

I don't know why but Intel recommends to monitor tcase temp and to keep it below 72.6 degrees max for i5 2500k. But if the core is getting hot beyond its limit then what good is tcase even if its below the max limit? I don't understand the logic behind their this particular recommendation.

^^ even I don't and Intel has no interest in publicly reveal it's cpu's core temp and same goes for AMD as well - why not cpu manufacturers are interested in specify tjmax ( cpu core ) temp is a great mystery to me and it's really a PITA to find the accurate tjmax temp of a cpu.

How's this?

*i.imgur.com/4WdHJ.jpg

^^ Just about perfect :wink:

. You can still lower your vcore but your temps are great for your cooler and that vcore

The thing is that I have decided I will never touch any kind of voltage option before buying the PC and I'm definitely gonna follow it

So yeah this is my final OC. Won't OC the CPU any more. Working on RAM OC now *devil*

Also you are right the kind of cooling my Hyper 212 EVO gives is really good. Didn't even buy an extra fan. Just with the single stock fan

Maybe its the overall effect of the ventilation inside the cabinet.
I have the members here to thank for that of course. Corsair 400R and especially the Silverstone air penetrator 120mm are doing their job wonderfully

^ yes I think your cabinet is definetly helping alot. In my cabinet everything is looking too cramped. As if everything has been just squeezed. Will think about going for a better cabinet in a month or two maybe. My front intake fan only cools down HDDs. I don't think even a bit of air from it comes to the actual area of all vital components. Ordered this fan from flipkart Cooler Master 90 CFM LED Cooler | Cooler | Flipkart.com . Got it yesterday but the screws provided withit just don't fit into the holes provided on the fan. I guess i will have to get it replaced or look for screws that do fit into it.

Guys I have some free time over the next few days and I wanna OC my CPU manually this time. I have already OC'ed (haven't applied the settings however) from my BIOS up to 3.7 GHz rock stable, with the lowest voltage and other modified settings. But I wanna OC it further, maybe 4.0 GHz if it's possible with my basic Hyper 212+. So firstly what software should I use? And as far as I remember I used Prime95 tests to check temp and stability, shall I keep using that or a better app is preferred? I will at first apply the settings of my 3.7 GHz OC and then tweak from there as needed.

Thanks in adv.

Re: CPU Overclock List &amp; Discussion Thread

Hyper 212+ is a good enough cooler for 4Ghz.
Prime95 is generally considered "the" software for testing the overclock. You could even turn to Intel Burn test later

You have a good cabinet as well. Maybe start with cleaning/dusting all the fans/vents and the components

1 day for cleaning and the remaining for overclocking

Even I ran into problems with fitting fans

The thing is that there's no threading in the cabinet at first. Threading happens as and when you put in the screws for the first time.
Check if your cabinet came with extra fan screws

Yea, sure. I will clean my cabby and components today. Excluding today I will have another 3 full days free, that'd do I guess. Still I need to know the software with which I can start working with.

I am not sure whether it would be possible to achieve 4.0 ghz on i7 950 with hyper 212+. Sandy bridge would have easily gone to 4.2-4.3 on your cooler not so sure about i7 950 though. Let others give their inputs maybe they can help you out with much more specific answer.

@Sharang.d The screws provided are fit for my cabinet, the problem is with the holes on the frame of fan. Either the holes are too small or the screws are too big. Its plastic body, so I don't wanna wrestle with it. I will check if there were any extra screws provided with the cabinet. I already have one same fan fitted as rear exhaust and there were no issues with fitting that one. But these srews with this same new fan look different and they definetly don't fit. If nothing works then I will have to use flipkarts 30 days replacement(which I swear is one of the best thing about flipkart).

^^ it's possible to reach ~4 Ghz but with Hyper 212+ high load temps would be an issue but if ithehappy has a D0 stepping cpu then he can reach 4 ghz with much less voltage and that should keep the cpu cool but still that may not be enough for core i7 950 @ 4 Ghz and Hyper 212+ - Op may get temps as high as 80-90c with stress test apps.

ithehappy said:

use Prime95 small FFT test or IBT and for temp monitoring use Hwinfo.

@TG- Thanks pal. But what's D0 stepping CPU?
And I asked for a software with the help of which I'll be able to 'overclock' and change other settings, like voltage and all. I know about Prime and HWInfo

4GHz in 950 with hyper 212+ isn't possible. You shouldn't even try it. 3.5 is the max limit upto which you may push your 950. I would ay 3.4 is the safe limit.

P.S. I can see everywhere in this forum that people are tallking about overclocking frequency without mentioning the architecture they are talking about. For example, that post which promopted you in posting this was most prolly referring to sandybridge overclocking. Stop this practice for maintaining good quality of discussion.

Yes i agree with you. I searched through google and many other forums before replying to him. All i could find was that trying to reach 4.0 ghz on i7 950 with hyper 212+ was not a good idea but since I wasn't sure hence the text you have quoted. I would have advised to stay around 3.5 but he said he already had a 3.7 ghz stable overclock, so I didn't comment on it.

P.S. yes the post above mine suggested that 4.0ghz was easily achievable but when I looked at the signature of OP i saw a totally different processor than sandy bridge thats why i replied like that. OP also didn't mention his processor in his post so I assumed that the processor in his signature is the one he is asking about.

If you've read my post I had clearly stated that I successfully overclocked to 3.7 using my bios, temp was within limitation too. So I thought if I could push further.

Tried -0.50 offset like you and my temp under load went down by 5 whole degrees!

what's the load temp you are getting at 3.7 Ghz ( and vcore ?? ) - 4 Ghz - well many have not reached that much without overheating issues ( core i7 950+ Hyper 212+ combo ) but if your's is a very good cpu chip ( High binned chips ) and has no heating issues you might be the one who would take the core i7 950 to 4 Ghz using Hyper 212+ - ready to set a new record ? ;-)

and this thread is for any ( OCable ) cpu .

Nice! yes the temps will go down for sure as your under load Vcore has dropped down by almost .1v . But if you see signs of crashes while doing menial tasks like browsing etc. try setting 1.26v manually and then reduce vcore gradually to find the lowest stable vcore. Main problem for me while using offset was that when it was under full load it ran smoothly but when I was doing lite tasks like browsing or watching videos etc I could see sign of crashes. I guess it has something to do with the drop in vcore while its idle.

No. I meant to say that when anyone is talking about overclocking, he should mention the architecture of the processor while posting about overclocking limit. Cause different architecture have different overclocking procedure and different amount of heat emission. Thus different type of cooling is needed for different architecture. So just pointing out the architecture while posting about OC'ing will help everyone to understand the topic and discussion properly.

As long as everything is stable, enjoy! but in case you see any signs of crash while doing normal tasks like browsing etc. try what I have told you in my last post. What is your idle vcore? Is speedstep enabled?

Re: CPU Overclock List & Discussion Thread

^Idle Vcore is 0.926V
Yes EIST is enabled.
No crashes even when idle.

@All why isn't there any option to set VCCIO in my BIOS? I can see only VCCSA.
Need to increase VCCIO to OC my ram. Help will be appreciated.
Could not find VCCIO setting in both 1204 as well as 1506 BIOS version. Mobo: ASUS P8Z77-V PRO

Also it's 4.3Ghz and not 4.2GHz

Gonna OC to 4.4/4.5 Ghz next week

What's the appropriate VCore for it?

^^ start with 1.3v and try to find the most stable voltage ( usually 1.35v / 1.365v ) but don't go over 1.4v

I'm running at 4.2GHz(with max temp of 70 with stress tests) as of now so I don't think 4.3/4.3 will be much of a problem. EIST manages everything well

Also cool season going on as of now ;P

4.4 GHz OC achieved quite easily. Temps are at around 60 degrees with prime95 blend tests. Will post with whole screenshots and everything after achieving 4.6 or 4.7. Will try that tomorrow. For now all i can say is that i absolutely love this processor. I mean overclocking with this one is a real breeze.

Because running a single cpu-Z version is too mainstream...

IDk but my bulldozer goes upto 5.0 on my HyperX 212

5 GHz is pretty easy on SNB, even a 2k cooler like Hyper 212 or N260 is enough provided you have the other factors right.

Re: CPU Overclock List &amp; Discussion Thread

That's fine enough then. i5 3570k can go to 4.8 GHz on those 2k coolers (factors right clause here as well

) .
Sumon da did 4.8 GHz with D14... I'll try to put my 3570K to 4.8 GHz over the weekend on Hyper 212 Evo. I don't think it would be big trouble as I'm running it on 4.6 GHz comfortably right now.

When you are just overclocking there's a huge difference between 4.8 GHz & 5 GHz.

my ES is pretty bad

in SB i could go 5.2Ghz

Can somebody lend me his D14 please

Skud said:

Agreed... and SB@5GHz will be as good as IB@4.8GHz.

Don't buy. You are not going to get 2x cooling or 2x overclocking by spending 2x over your present setup.

IB cpus ain't great OCers on Air - it's a known fact but you need less voltage to get ~4.8Ghz compared to SB cpus.

Now talking about OC where even a single Mhz counts to set record things like this really matters greatly.

I was playing Battlefield 3 yesterday, everything maxed(Ultra). Game was running smooth most of the time. But sometime in middle it stucked for like some milliseconds. And when I checked my processor temp it was 84C. My H80 went for RAM so have reference cooler now. But 84C is too much. I didn't overclocked my CPU, but voltage was set to 1.47V by BIOS. So, I changed the voltage to 1.3V.

Can anyone tell me, is i7 2600k runs this hot with reference cooler at stock speed.
And what should be core voltage.

Room temp ? Check ventilation inside cabinet. Might want to redo the thermal paste.
My 2600k, with stock cooler, does a max of 60-61.

Myth said:

I thought so. I didn't cleaned the previously applied thermal paste. I didn't had tools to clean it
at whats core voltage you are running proc.

I havent OCed the proc.
vcore is around 1.24 max.

1.47v for 2600K? that's too high dude....

I think with that much voltage Op can easily hit 4.9-5 Ghz ;-)

but seriously why would OP need so much voltage to run the cpu at stock speed ? I think for stock speed 1.2v is enough.

Re: CPU Overclock List & Discussion Thread

sumonpathak said:

Day before that I made a bios update. That might have caused that.
I never went above 1.35V for 4.8Ghz overclock.

Tried my hand in OC'ing yesterday after a long time as a part of testing out asrock board.
Processor: 2500K ~~@4.9Ghz vcore: 1.34V~~ crushed at last. @4.7GHz vcore: 1.32V (previously stable)
Cooler: hyper 212 evo push pull.

max temp: 71C
ambient: 20C
p95 stable after running for 9 hours.

Yet to test out that 2500k with h100 & d14.
Looks like I got a good chip.

You forget to post the screenshot.

Re: CPU Overclock List & Discussion Thread

This is the max teh so called Hyper 212 evo (no push pull, single fan) + extreme6 can do:

Bad performance.

Nice OC. Can't say the same about the temps though. That CPU seems capable of more.

Re: CPU Overclock List & Discussion Thread

I mean pathetic LLC.

That's why extreme 4,6 should be avoided and shouldn't be suggested.

If you can get it stable @4.7GHz with 1.33v, your chip can do some serious OCing.. And the temps are fine BTW(for a hyper 212 @34C amb.)..

Its actually 1.32V. I can see the voltage flactuation in cpu-z, which must be due to bad motherboard, and it doesn't happen with any asus board I have.

you are going to test the 2500k using H100 and D14 - on this 'crappy' Asrock mobo or you will use some good Asus mobo ??

cool, you reached highest stable and highest clock speed both using very low amount of volt and you used the NH-D14 to keep things cool ?

yups...this runs cool.

I guess you guys have understood about the Park Control - CPU Parking application Sumon was using. Core Parking is a feature in Windows which maintain different Power states in different CPU cores to make it stable or optimized. Since Windows 7 has poor scheduling for all the Bulldozer and PileDriver Processors, it negatively affects the performance. So switching off the feature increases performance for BD Processors, sometimes by a big margin, in expense of higher power consumption. The software Sumon has used can Turn On/Off Core Parking on the fly without touching the BIOS and without the need of Reboot. Currently I am doing couple of tweaking to improve BD performance by using different Windows and AMD software. Will post a guide once finished.

What is this cinebench benchmark software, as compared to 3dmark, prime95 ? Is it something like siSoftware Sandra ?
I assume the Park Control (provided by amd ) application is separately installed.

Now I understand.
Looking forward to your guide.

perk control is not made by AMD.
Also Cinecbench is more realistic than Prime 95 as it does not heats up the processor unnecessarily..

Here goes couple of results after my tweaking:

Power Mode: High Performance; CPU Speed: FX 8150 @ 4.30 GHz (21.5X Multiplier using AMD Overdrive), Turbo Off; Memory: 16 GB RipjawX (4GB X 4) 1873 MHz 10-11-10-37 2T

@Cilius: When do you plan to compare the 8150 and the 8350 ? Or does that depend on Sumon returning the 8350

Making a list of benchmarking softwares.

Sumon has returned it to me. I am currently going through the FX-8150 tweaking. Once done, will use the FX-8350. Actually due to my poor health condition, not in very fast Mode. BTW, did u check that in couple of Benchmarks, FX-8150 is head to head with i7-3960X and in fact ahead at CPU Hash Benchmark.

Yes, the 8150 does take a very decent lead in the cpu hash benchmark. Ocing seems to suit the 8150.
I think the 8350 might fare much better here.
In core temp, the max temp was 38C ?!?!

Get well soon.

Temp is too high bro..use an aftermarket cooler

^^^Ohh thanks bro. Do u know what is the safe range of temperature for this CPU? And plz suggest me a good aftermarket cooler at lowest budget as possible (<1000).

look for deepcool gammax or hyper TX3 Evo

as for temps..somewhere in the 50's for load temp is ideal..

guys what do you think,is it safe to go above 1.5v vcore as i still have temp headroom(its 58C at load and don't worry about winter its as hot as summer here and also i am using single fan for cooler so another fan will reduce temp and also my 400R can some more case fans. :wink:

)
btw it booted at 4.4GHz @ 1.5v without any problem.may be it will boot even at 4.6GHz without any problem.

^^ you have got an excellent chip but don't go over 1.55v - thye 4.3Ghz should be stable at 1.5v though.

@ max_snyper - 4.2Ghz and the Corsair H100 ? you can take your cpu for a wonder ride - set it at least 4.8 Ghz and see how the cooler holds up.

@sukesh1090

Nice Bench.... With 4.3 Ghz the Cinebench Score is 5.05? I thought it will be much more than that.

@max_snyper

To know your Overclock stable or not... Just run Cinebench 11.5 once. If it is done successfully then it's almost 95% stable..... :-D

Just kidding...Burn Tests are must but Cinebench will crash your systems if overclock is not stable.

You may push it further (say 100-200MHz) by disabling HT.

Nah, a bit worried with the volts, just wanted to see if I can push it further than last year.

The 1.472 vcore seems a bit high. How far can the 2600k go on default vcore ?

Need a slight voltage bump for that, don't want it. 4.3 GHz is the max I can get with stock volts (not Auto) and turning PLL overvoltage off etc. while keeping everything stable.

^^ Ok, buddy.

@ somebodysme - try with 1866 Mhz for vengeance 1600 - make use of the Memory Frequency, mem volt ( only if needed ) and Dram timing option.

Everything is stock, no not going into details, just mentioning the settings which I have chagned for the OC.

I didnt touch vCore / RAM / multiple or anything. All I did is increased the FSB of the processor from default 1066 MHz to 1333 Mhz. Which took the 2.4 GHz stock speed to 3.0 GHz

Thats the saddest part..

I used to have a Nvidia 650i based board, there with Corsair DDR-II running @ 1000 MHz, this processor was able to clock 3.8 GHz stable for long term use.

In winter I used to touch 4 Ghz mark also, but in summer, 3.8 GHz was the edge of limit for it.

However ever since my Nvidia 650i based died

I didnt have any other option apart from G41. This G41 linked with RAM is not allowing me to go beyond 1333 MHz as taking RAMs (at present DDR-III) over that is resulting in no BOOT

.

Oh .. anyway, the 3 Ghz speed you got is fair enough and still plenty for all of the latest games - this ages old quad core cpu still holds some strong performance.

Never felt the need of replacement recently when in Windows 8 and Server 2012, it refused to run native virtualization with error for SLAT not being supported by the processor :punch:

Microsoft didn't play fair here, not supporting native virtualization platform for these C2Q series.

Sumon, i request you to provide me a possible Over-clock profile and step by step methodology to ramp up i7-4700MQ mobile CPU.

highlight on below points would be greatly appreciated.

1. Points supporting the overclock as to why i should or should not.
2. Performance gain if overclocked and its advantage in gaming performance.
3. How to overclock CPU, haven't done ever, so step by step process with tools and s/w details to track, tune and upgrade.
4. All overclock profiles, i would prefer a moderate oc, not extreme, keeping in mind the heating. all configuration settings for the same.
5. Any cooling solutions i should implement or have before/after overclocking and how to get it/from where.

You can PM me with the details or post on top of this...thanks in advance

very nice job done on that 220W monster and if it's bench stable just wondering what's the load temp cpu bench/stability test apps.

Sumon, i request you to provide me a possible Over-clock profile and step by step methodology to ramp up i7-4700MQ mobile CPU.

highlight on below points would be greatly appreciated.

1. Points supporting the overclock as to why i should or should not.
2. Performance gain if overclocked and its advantage in gaming performance.
3. How to overclock CPU, haven't done ever, so step by step process with tools and s/w details to track, tune and upgrade.
4. All overclock profiles, i would prefer a moderate oc, not extreme, keeping in mind the heating. all configuration settings for the same.
5. Any cooling solutions i should implement or have before/after overclocking and how to get it/from where.

You can PM me with the details or post on top of this...thanks in advance

Is it even possible to OC 4700QM and what about the heat ? If you want to gain additional performance better stick with gpu oc if you can manage the heat.

I got 4.9 ghz cinebench and bf3 stabilty....this was a pure suicide run....for single thread benchmarks...

Sam , you shouldn't try Overclocking Mobile CPUs from Intel.
IvoryBridge onwards the mobile CPUs were damn too hot to be overclocked beyond the turbo boost limit.
In fact my IVBm reaches 95-98C on 2-3 Cores just like that , when at Turbo. And It has a Tjmax of 105c , so it's dangerously close to the upper limit.

BTW, you can look into overclocking your laptop's GPU ( I think you have a Xenom laptop with some kepler 2nd Gen GPU. )
That should suffice and will give considerable boost in performance. But for the CPU part it would be too risky to even try for the additional performance expected which would be very marginal.

TG ,This time they changed the name to MQ instead of QM . :wink:

makes us 3rd gen owners confuse ourselves. haha
And yeah I highly doubt that's its possible to Overclock that chip because it's not a K-Series Chip.Even if it's remotely possible to overclock it , I highly doubt someone would be able to find the solution so early.
Plus , I looked into the TjMax of the Chip and it seems that it's even lower than IVBm chips. It's reduced to 100C from 105C of IVB. That makes it even harder.

^^ OCing is getting a tough business on Intel platform

and with so many products [ read cpu ] released in a short time frame sometime it can get really confusing

@ sumonpathak - so what's the load temps under BF3/Cinebench @ 4.9 Ghz - I just want to know how much heat this big green monster can generate

Thanks Sumon for helping me ocing the proccy to a good 3.61GHZ, 730 score in XTU bench, good enough for me and a locked i7 mobile, gained around 3% in crysis3 somehow, temps 87-89 at GPU, 80-84 at processor cores.

:shocked: ,
Pic or it didn't happen. ( 84C on all four cores at 3.61Ghz ??!!!!!)

its only 3.4 to 3.61, how much u expecting 98 deg? the laptop has dual cooler with a 4 fan deepcool multicore X8 installed in its butt, i get 33 deg in idle at GPU, now am pissed with the 38-39, i was planning to oc the GPU as u suggested, but ditching the idea, also will downclock the cpu today to normal, too lame OC

did not make any significant diff in any games except crysis3, bad luck for me with this proccy.

This was in summers at room temperature for a couple of mins of gaming.
And the CPU was not even at full blow of 3.1GHz on all four Cores.

sorry my office laptop lacks the perks of showing a pic properly sometimes in a forum , anyway i seat in a 16 deg ambient AC room when i play games for more than 4 hours stretch.

care to share the OC procedure ?

If it's possible and safe then it's better to Overclock two cores rather than all four cores .Most games(<2012) don't use all the four cores.

nothing much, Sumon was online in FB, i installed the intel XTU, he suggested to increase the multi to +1 uptil max. so all cores were finally 36 35 34 34, ran benchmark and the score was 728, then i found some other profiles with better score in XTU bench, downloaded and applied, the difference was in graphics section where the value was 28.5x instead of default. The proccy was alredy running at 3.6 Ghz by then, i ran benchmark and checked online again after applying the change , the score was 730. thats it.

Yeah well I have four 80mm fans blowing air right on it's butt , spinning at more than 3000RPM. Keeps it under 90C for CPU and 80C for GPU(20%Overclock Profile) when they are running.
But still The 3610QM generates hell lots of heat when at full blow.

BTW , isn't you processor non-k series ? Which means it shouldn't allow Overclocking unless any hack or mod is applied ?
I have used the same application (XTU) , but all I get to overclock is the boost of iGPU , but not the processor.

i thought that too, and i also checked the bios which told me "u cant oc this proccy" but i got the doubt running coz i had this XTU utility factory installed, so i tried some tweaks in it ( was really nail-biting while doing it), also sumon confirmed that i can not oc this CPU. but XTU was worth a shot, clearly i am missing lots of settings as compared to a unlocked proccy, that was the furhets i could go with 3.61 ghz, which is a shame in the world of OCing ...shame

Thanks for the info.

can i reach the 900/2700 GPU/mem from 771/2500 with my GTX780m, i read that the power consumption will be higher than 191W in such oc'ed level where as my Power Supply is limited to 180W, is there any tool to check how much power my GPU is actually drawing from the wall despite the 10% loss in AC/DC conversion?

there's no tool which can show how much power your gpu is drawing from wall .. however there are tools with which you can measure the laptop's overall power consumption or the power consumption of the gpu via pci-e slot for. eg. Keithley Integra 2700

Does it work for all laptops ??
Thanks.

may not all as it can measure power consumption via PCI-Express power connector(s) and PCI-Express bus slot anyway, I've never seen someone measuring laptop gpus power consumption except from the manufacturers but they must have some expensive and sophisticated hardware for that.

Don't you think it would be better to segregate the list now on basis of architecture and brands?

hmm, nice idea and I've thought of something similar before but it may be either laziness or lack of time which made me refrain from doing it

but I'll do it for sure.
BTW, currently trying to figure out the puzzle of AMD FX vs Intel in gaming

to all senior members in TDF...

Where is the TDF bench! Its been long since i came across any benchmarking done, extensive product reviews on newer GPU, CPU, architecture and their advantages, comparison bench, test bench, and more specially the over-clock bench. I'm not talking what other tech forums are doing and what TDF should do, but a very contributing part of a tech forum dictates that there should be a comprehensive section of where real bench-markings are done and discussed over. There are plethora of products to bench with, OC with, even OC guides on new GPUs, new CPUs...where are they?

The only thing i see over threads is copied versions of benchmarks from other forums like toms, anand, guru3d and so on and so forth, but TDF IMO should have their own bench team who does that, doesn't it? with a superior reader base and so many knowledgeable personnel here in this forum, why is there very few of real-time reviews?

The hardware you need is called Kill-a-watt. It is connected between adapter and main power supply just like an extension cord. Google it.
If your motherboard's wattage requirement exceeds the supply then your screen will switch off, this has happened to many times when I was using stock 120w adapter.. Also all overclock will be lost but the kernel won't crash which happens when you OC too much.

I got a C2Q q6600 revision G0 on a gigabyte g41m combo M/B. currently i'm running it @3.0 GHz with multiplier at 9 and bus speed at 333 with FSB at 1333. the Vcore has been raised to 1.275v
If i decrease the multiplier to say 8 and increase bus speed to say 375 to again run it @ 3.0 GHz, will it make any difference in performance and temperature? or say run it @3.2 GHz (400 bus and multiplier 8)

Undervolted the Athlon II X4 635(2.9GHZ) from 1.4v to 1.175V

@Topgear,
we should have a Undervolt at Stock Clocks,

it'd be interesting to see the demographic.

This is the CPU overclock thread....

A first time overclocker here. Overclocked my signature CPU from 3.2 GHz to 3.6 GHz just now. It was apparently easy as it's a Black Edition CPU. Just increased the multiplier to x18 to achieve the overclock without fiddling with anything else. Posting a couple of screens of the BIOS below. Please let me know if anything looks abnormal or suspicious.

Everything looks fine but you should not perform OC on a motherboard without VRM heatsink specially if the cpu is of 125W TDP. Anyway, I think this mild oc should be just fine though.

Re: CPU Overclock List & Discussion Thread

I got a Gigabyte G41m-Combo motherboard with a Q6600 OC @3.0 GHz (333 x 9). Was thinking to OC it a bit further.
I was looking around in the BIOS settings and came across DRAM settings options:
1. Performance Enhance - Standard (default)
2. MCH Frequency Latch - Auto (default)
3. System Memory Multiplier (SPD) - Auto (default)
This way Memory frequency is at 1333 MHz (thats the maximum supported by the board). Then fiddled around a bit and changed the above three to the following:
1. Turbo
2. 333 MHz
3. 3.2 B
This way the Memory frequency became 1066 MHz.
Does this mean that now i can change the FSB to get a higher clock (Above 3 GHz)? LINK to a previous thread of mine for a different OC querry for same setup (pics).

- - - Updated - - -

Another thing....the last time i ran prime95 for 2-3 hours, the system was stable and temps never crossed 70
Yesterday when i ran prime95 w/o the above settings, one worker stopped after a couple of minutes. pumped the Vcore a bit and then second time, another worker stopped after 15 or so minutes. Is it common to be stable at one time and fail some other time?

topgear said:

Should I just downclock it then? Will it have any negative effect on my components in the long run? Is a VRM heatsink required even when I've not modified any voltages? I've not noticed any rise in temperatures after overclocking (Monitored through hwinfo & hwmonitor). Sorry if I'm asking noob questions. :noob:

Prime95 could be buggy but 2 - 3 hours of prime95 run is not enough for stability check. You can go higher but that would depend on vrm cooling, vcore needs to push the cpu more and strength of NB / MCH. As for a personal opinion I think you've reached the limit with such a budget board.

as long as you don't need additional vcore I think you're good.

has anyone of you come across any article which explains or experiments on Under-clocking a Mobile Intel Core I series processor , like I3/I5/I7 SB/IVB . ?
Summer is back , and the scorching heat in Delhi makes the Quad IVB CPU really hot while playing games , and being a laptop CPU , you just can't help it much , ( IVBM are notorious for it ).

See you can't undervolt/underclock the cpu without BIOS support. You have to flash a custom bios to obtain bios support. This WILL void the warranty. I was able to undervolt AND overvolt my CPU(3632QM) using this technique.
I think Overclocking and Underclocking are not possible with normal IVBM, you need a XM proccy for that.
A much better alternative is Arctic Silver V. BTW what temps are you getting?

Peak 90's.
I already have a modified BIOS , but that serves a different purpose. I don't think I will be able to find a modified BIOS which allows modification of CPU settings.

Newbie overclocker here. I will post final screens after I finish my final Oc.

So I bought the 8320 and was running it on 3.8Ghz. Went to 4 last night and tested with 2 hours of prime95. Seems stable enough.
*i57.tinypic.com/dws3tu.png

"The socket temp was 70 degrees. It jumped to 71 when I clicked the screenshot unfortunately. But I kept prime95 on for 10 more minutes and it stayed at 70. And I am pretty sure a small fan at the back of the motherboard and another as a side intake will bring it down to 65.

*i57.tinypic.com/k2gv21.jpg

Now I have a few questions regarding the HT Link speed, the CPU-NB speed and the cpu voltage.
The default values for both were CPU-NB and HT Link were 2200 Mhz.
Can someone please explain what both of these do? And should I keep HT link at 2400? Or should I set it to the default 2200?

Also, The cpu voltage, I left it at auto. And usually it is 0.98(c1e etc power saving enabled) to 1.35. But once I saw a max value of 1.42.
Is this safe? Or should I manually set it to 1.3 /1.35?

I miss overclocking ever since I shifted to Intel Camp. K series too Expensive and AMD not even close in performance / power ratios.

what once was a nice hobby+necessity now turns into only hobby by serious overclockers. Even I miss the good old days of OC when you can cpus frpm both campaign. Anyway, anyone tried OCing android devices ?

i overclocked my xperia L just after few days of buying, and then always kept it at ~1.75GHz cpu and gpu at 450Mhz ( maybe it was 1.725Ghz but it was above 1.7Ghz) (stock was 1GHz cpu and 400mhz gpu)

though during hot environment it used tosettle at 1.4-1.5Ghz at full load ( thermal throttling, though always remained below 60'C )

kernal was downloaded from xda developer , i don't know how to modify kernal else i would have definately tried for 2GHz

and some small heatspreader onto the soc

and now i mis those days
my current asus zenfone 4 have no developer support, not even custom recovery ( even my old karbonn a5 used to have custom roms and recoveries ) , some root is available but if something goes wrong then only way to make it work is to lie to service center guys so can't even root , this is why i feel like i am missing out on something

y u no developer support asus :'(

did not know that Asus zenphone is this bad .. I was thinking to get one but now I changed my mind. Thanks. BTW, OCing is getting more and more limited each day beit on pc or other platform but if anyone don't mind the performace part AMD still kept the legacy of OC live.

Quite unlikely.

Hi I dont know anything about Overclocking just want ask
Is bios update necessary?
Motherboard:- ASUS m5a97 R2.0
I'm not overclocking

If you are not facing any sort of stability / other issue issue then don't unnecessarily update bios.

Guys I upgraded my system and naturally have dumb queries. You see I bought RAMs of 3000 MHz, but my board supports up to 2100 MHz only, so I need to OC the RAMs. Now I know I need to use the XMP profile, but while selecting XMP from BIOS this message pops up, and I am not sure which one to choose. I am told to click on the Yes option but won't it somehow OC the CPU too? I only want to OC the RAMs for now, nothing else.

*i.imgur.com/3CuIGPw.jpg

Basically what will be the differences between choosing Yes and No?

^Thanks for sharing. The guy in 1st video is running 3.85Ghz at 1.38V which is high IMO. Mine reached 3.85Ghz with less voltage IIRC, though I ran the stress tests for not more than 30mins. I try to stay below 1.35V and in our ambient temperatures, staying under low temps is also difficult. I'm happy with 3.7Ghz as of now with max temps of ~65c under load.

Buy a good cooler for OC, stock cooler is not recommended for OC.
Your CPU will die down earlier with Stock cooler OC.

How to overclock an AMD Ryzen CPU

A step-by-step guide to pushing your AMD Ryzen processor beyond its limits.
*i.imgur.com/tuozxYs.png

AMD's Ryzen CPUs are its fastest, most competitive parts in ages, but the universal truth still applies—you can make them even faster by overclocking. AMD encourages users to tweak their platform, and you can level the playing field between the first- and second-gen Ryzen CPUs by using AMD's own tools and advice to overclock your processor. Make the years disappear and your processor will feel like new again.

We'll walk you through everything you need to know to overclock a modern AMD CPU. There's still plenty of life left in AMD's first generation of Ryzen CPUs, but if you have a newer Ryzen processor you can still get in on the fun, and here is our guide to the best CPUs for gaming. Our testbed was a Ryzen 1700X on motherboard along with 8 gigs of 3600MHz TridentZ G.SKILL DRAM, but all these techniques work just as well with newer processors and motherboards. While there isn't much risk to overclocking these days, there's always a chance for damage when you run hardware beyond spec, so keep that in mind as you proceed!

Clean before you overclock
Believe it or not, one of the most important steps in overclocking a PC is making sure the case, fans, and heatsinks are clean and clear of obstructions. Even the best watercooled system won't operate with blocked vents, clogged fans or dust-encrusted radiators, and every PC eventually develops these problems. Open your system and give it a top to bottom clean-up. This is especially important if you haven't cracked open the case in more than year. It may be scary in there.

Rerouting cables behind the motherboard is a great way to improve ventilation. Not only does this improve the efficiency of your cooling system, it also looks much better through the side window, showcasing components and LED lighting effects.

Speaking of cooling, if you want the most out of an overclocked system, you'll need to go with at least a budget upgraded air cooler such as Cooler Master's Hyper 212 EVO. Check out our guide to the best CPU coolers at a variety of budgets.

While the case is open, check your power supply to make sure it has enough juice to handle the extra load an overclocked processor will draw. If you're already pushing your power limit with a low wattage model, it may be time for an upgrade to a certified 80 Plus Gold or better PSU that has a few extra hundred watts to spare. Not only does that eliminate the hard-to-pinpoint problems caused by uneven power delivery, it also prepares your rig for any future upgrades urges, such as a hungry new graphics card.

The software you'll need before you overclock

You'll need several software tools to successfully overclock a system, but they are all easy to find, free, or cheap, so this part is easy. First, pick a few games with good built-in benchmarks so you can test your system before and after with real software. While the type of game depends on your tastes, good CPU gaming benchmarks include the Total War games, GTA5, and Hitman. Chose a lower resolution, such as 1080p, and moderate visual settings so you don't wind up stressing the GPU more than the CPU.

Next up are static benchmarks and stress tests, to see how much performance you've gained in a more controlled software setting and to make sure the new CPU speeds are stable even when the processor is pushed to the limit. 3DMark's Firestrike and TimeSpy have CPU tests that are good benchmarks, but AIDA64's stress test and static benchmarks are favorites due to their speed, depth and ability to tease out errors quickly. Traditionalists will prefer Prime95 and Memtest, although the former may work your processor harder and hotter than required.

To prep your PC for its overclock primping, visit your motherboard manufacturer's website to check for new motherboard and chipset drivers, especially any BIOS updates. Ryzen has come a long way since launch, and you want every advantage a new, stable BIOS brings to the table. Consider upgrading graphics card drivers also, to start with a clean, up-to-date slate.

How to overclock an AMD Ryzen CPU

Overclocking is traditionally done on your motherboard's BIOS screen. To enter the BIOS, you'll have to press a key during boot up—usually a Function key, DEL, or ESC. The key you need to press should briefly be displayed on-screen during the boot process.

Once in the BIOS, it's time to dive into settings and start speeding things up. The clockspeed of a CPU determines how quickly it performs operations, but raising it is not as simple as dialing in a new number. Processors use two values, the base clock (BCLK) and the multiplier (also called Core Ratio), to determine the final clock speed.

A system's base clock, usually 100 MHz, determines CPU speed as well as the speed of a host of other subsystems on the motherboard. While slight bumps on this value raise CPU performance, it's far more likely to cause instability since every other component that uses it is also overclocked, and most of those subsystems aren't as tolerant to overclocking as the CPU. For beginners, this is best left alone, although experienced overclockers will often tweak this value slightly to squeeze the last few MHz from an overclocked CPU or to get the most from high speed DRAM.

Changing the multiplier only affects the CPU speed and is much more forgiving to overclocking shenanigans. This is where most of the speed increase takes place. As the name suggests, the top CPU clockspeed is determined by multiplying this value with the base clock, so a multiplier of 40 and a base clock of 100 yields 4GHz. For most Ryzen CPUs 3.9 to 4.2 GHz—via multiplier—is the ceiling people hit when attempting an overclock. The second generation Ryzen parts (specifically the 2600, 2600X, 2700, and 2700X) will typically do 200-300MHz more than the first-gen parts.

Keeping the cores fed with power at higher speeds so they remain stable often requires an increase in CPU voltage as well, and your top speeds will be a balancing act between voltage, multipliers and heat. Ryzen responds best to CPU voltages (or VCore) of around 1.35-1.37V. Higher voltages up to 1.45V are possible but require exotic cooling solutions and may shorten the life of your processor, and we don't recommend them for anyone reading this guide. Keep temperature below 80-85C. Ryzen processors don't like going beyond that temperature.

We recommend starting with a manual (not automatic or offset) voltage of 1.35V. Then set your core multiplier to 39 (aka 3.9GHz). Save the BIOS settings and boot into Windows.

Test with a couple of benchmarks and a stress test, and if no problems pop up, raise the multiplier by one and repeat the process until instability occurs. If you got lucky and have an overclocking-friendly CPU, you can generally push past the instability by raising voltage slightly and testing again, but every chip is a bit different. Keep an eye on temperatures, as increasing voltage can have a large effect on heat and may prove counterproductive depending on your cooler.

Eventually you'll reach a wall where raising the speed even a little bit will require a big voltage bump, or the processor becomes unstable to matter what you do. We'll give you a few pro tricks in the section below, but if you want a nice simple overclock, this is the end of the road. Ease back from the edge by 1 on the multiplier for a safety margin and run benchmarks, stress tests and some demanding real-world software.

Hitman or The Witcher 3 are good for this—both tend to crash on unstable overclocks. If everything checks out, you're good to go.

Going beyond the overclocking basics

There are a few more tricks to raise speeds just a little bit further. Early on, Ryzen had problems with faster memory sticks and while these issues were addressed quickly, many users still have DRAM set to the most compatible and stable speed settings. A lot has changed from those early days, and if you have an enthusiast motherboard it's likely to handle whatever memory speed you can toss at it, so it's worthwhile to check and see if you're running those DRAM sticks at their rated potential. Ryzen systems leverage fast memory more than Intel-based hardware, especially AMD APUs, and you'll feel the difference if you're still running at the chipset's default 2400 or 2666 MHz.

Like the CPU, DRAM voltage can also be raised for stability. A value of 1.35V is best for this if the default value isn't enough. Keep in mind that memory tests can take a while, faulty settings are a pain to troubleshoot, and DRAM tinkering can cause OS corruption. Stick to the various listed speeds provided by the memory manufacturer, rather than rolling your own timings, unless you have tons of tinkering time to kill.

Your success in overclocking Ryzen processors often will depend on what CPU you're using. The latest Ryzen 5 2600X and Ryzen 7 2700X have base clocks of up to 4.2/4.3GHz, and features like Precision Boost often do a good job of using all the available headroom. Because overclocking Ryzen CPUs disables turbo speeds, you may not end up with a meaningful improvement.

The non-X processors like the Ryzen 5 2600 and Ryzen 7 2700 CPUs on the other hand come with more conservative clockspeeds at stock, and often overclock nearly as high as the X variants. This is true of both first and second generation Ryzen processors. If you're looking for the best value for Ryzen overclocking, we recommend the less expensive non-X models.
