I got
AMD Phenom II 955 BE (3.2Ghz)
Asus M4A78 Series mothrbord
4 Gb DDR3 Ram (1333 Mhz)
1 GB HD4870 (MSI graphic card)
600 W Cooler Master SMPS

Can any one tell me How much can I overclock My CPU without Melting it :neutral:
And How to Overclock it??

Please..:smile:
Thanks In Advance

Google AM3 overclocking guides. Monitor temps, should not go above 61, which is AMD specified limit. Get a good CPU cooler like the OCZ Vendetta 2 @ 2.6k before you clock it.

i once tried to overclock my pc it gave a blue screen and restarted...
i tried several times but same thing happened..
me too wanna overclock my pc but dunno how to anybody can help...
i always keep my cabinet open... does it help to keep the PC temp. low ?

@puneet config please. If Intel, asigh can help you.

@ rohit CPU cooler first. then clocks.

Could both of you please update your signature with system specs. Also Compaddict is worried about the OPs PSU. Lets hear on that before imparting OC methodology...which we love to do so...! :p:p:p:p:p:p:p:p

ok...thanks krow bro see my config in my sigi
i dont even know the abc of overclocking...
so please teach me considering me a noob :D

1. Which PSU are you using.
2. Are you on Stock cooling for the CPU.
3. Could you download CPU-Z and post screen shots of the CPU/Memory and SPD tabs.
4. Download RealTemp and Prime95 also.

^Intel Burn Test would be my recommendation. It gets done in lesser time. :)

^^ Does it make a temperature log simultaneously which can be easily posted here...with the core temperatures.

Am asking, since it never even launches on my system....! If yes, we can use that for analysis..?

^No, it does not. For a simultaneous log we can use OCCT linpack I think.

Then I suggest for this case, since we need online screen shots, RealTEMP in conjunction with Prime95 will do good. The OP can definately use Intel Burn test to verify system stability for his own sense.

@OP:
Will get back on the OC. Mean while, there is an OC thread in the 'CHIT CHAT' section. It has a flow chart. See if that makes sense.

What about the PSU, and HSF question I asked. 'Help us to help you'

^Same thing can be done with RealTEMP plus Intel Burn Test right? Or CPUID H/W monitor with Intel Burn Test? That's what I did at least. :)

^^ Not really...

Cause when RealTEMP sensor check option is used, it at the same time stresses the CPU as per Prime95 (2x worker threads), and logs the temperatures on the interface. It is calibrated against TjMax, which we need for Intel cores. With Intel Burn test running, it would just show one singular value on the RealTEMP interface, same with CPUID.

I want to see the gradient, and variation when the core is load is being sequentially increased. RealTEMP logs this in stages. And all the stage temperatures are shown..

It does it like this:

See the temperature logs at various intervals. With Prime95 as the stressing engine.

What is Temperature Junction Max?

asingh #21
Nov 10, 2009 at 11:48 AM
It is a specification for Intel CPUs. When the CPU temperature reaches this point, it will start to throttle. It can be adjusted in RealTEMP. If TjMAX is crossed, and the CPU sees it will get killed, it causes a system hang / or BSOD.

Fail safe done by the CPU, to protect itself.

hey asigh bro please help me out i posted what u needed
what else do u want to know please tell me
i really need to lean overclocking
and as for PC temp. i keep my cabinet open...
does that help with the lowering of PC temp.
i really dont have any fan installed in my cabinet
And regarding PSU its Intex smart 450 Watt

checked out ur drawing on OC
but was not able to understand :(

i'll conduct the tests and post the images over here

OK..man...here it goes....

First of all lets down clock your system to the most stable basic level. All ready your vCore seems high to me.

1. Go to the BIOS and disable all power saving options. (You will have to research this, I do not know that much about ASUS). This is very important.
2. Lower the vCore to 1.2V and commit the changes.
3. Get to the desktop, and using CPU-Z see if the new vCore is reflected.
4. Run the stability test using ReatTEMP with Prime95(2x threads).

Keep lowering vCore in decrements of 0.1V till you get instability. Repeat 1--->4.

Once you have a stable system with the lowest possible vCore, run a FULL Furmark Benchmark or OCCT burn test. System should HOLD.

If it is stable, post a screenshot of (4).

This will give us the base level benchmark for your system. And will also get your hands dirty, for initial OCing.

Post this we move to the 'actual OC'.

Best of luck.

but what about these tests bro...
i was conducting them to post results here
should i continue conducting them or should i stop

Via RealTEMP use Prime95...using SENSOR TEST.

You lowered the vCore, and disabled Power saving options from the BIOS..?
puneetgarg
Nov 10, 2009 at 1:11 PM
no first i have to do that...
but in OC thread it was written to show these tests like this
so i was conducting these
read ur post late...sorry for that
so should i try lowering that first and then conduct these test using vPrime or let it continue for 1hr as was said in OC thread and then post its result here

Each time you make a change to the vCore, FSB, multiplier, RAM timings, FSB : RAM ratios you will have to run stability tests.

Run the stability test with Prime95 and RealTEMP. Seeing the gradual load increase with the temperatures, makes it easy to assess the situation.

bro im not getting it
how can i know after changing that my system would be stable
i mean running sensor test on real temp with prime95
how will i come to know that my system is stable
does it show some error or something

Well just found out, on your motherboard, the vCore cannot be changed. :)

Disable the speedstep.
Try to change the Actual FSB (QDR) -- and see if it increases the CPU Speed. It should reflect there only.
