Asus P5B Delux or others(P5K3/P5K)?

orc said:

Hi all,
I have this configuration now:

Intel 915 GAV mobo
2.6 GHz P4 HT
ATI 1950 Pro gfx card
768 Mb RAM
320 GB SATA hdd(2 x 160GB)

I want to upgrade to an Asus mobo since I need overclocking capability. I am thinking about the P5B Delux. Based on your experience do you recommend the P5B Delux or can I go for someother mobo? My max budget is 12k (hoping I can use my present proc (2.6 P4 HT) for sometimes on the Asus till I can afford a C2D).
Also I saw on Asus site that the p5K3/P5K were now availabel in India. What are your views on those?

I would buy Asus P5K Deluxe.P5K3 is useless as of now cos its for DDR3 which is insanely expensive.
I dont think P35 boards have arrived yet

hey darky how r the asus p5k-v and p5k-vm boards based on the g33 chipset???
r they good overclockers???
r they available in india??? wat shd be the prices??

As of now P5K-VM seem to be available but are idiotically priced at around 9k+ :ROFL:

Anyways G33 is supposed to clock 400 FSB + out of the box.I am not too sure how Asus has implemented these boards.I am not sure about the BIOS either.
I would suggest waiting for P35 boards.
Interestingly the vcore on P5K Deluxe is a meagre 1.7V
Its strange especially taking into consideration the fact that Asus P5N32-E has insane VDIMM like 3.4V or so

So how does that affect the overclocking? Does it put some serious limit on oc?

With Asus's legendary Vdroop, trust me 1.7V Vcore will be a limiting factor

For example,
When i cracked 4 GHz on my E6600 it needed 1.69V [Real] Funny part is i had set vcore at 1.735V in BIOS and i got 1.69V REAL.
So you see why i say 1.7V wont cut it ?

I just found this:

"One of the drawbacks we saw in previous generation Asus mainboards on iP965 chipset was the significant drop of processor voltage as a result of increasing CPU utilization and, logically, power consumption. Although such behavior of the processor voltage regulator doesn’t contradict Intel’s specifications, overclockers were pretty upset that the Vcore they set in the BIOS Setup was forced down. The new P5K Deluxe mainboard doesn’t suffer from this drawback anymore thanks to a special CPU Voltage Damper option. If you enable this option, the processor Vcore will not drop down more than by 0.032V (according to our measurements taken with Intel Core 2 Extreme X6800 processor overclocked to 3.2GHz). If the option is set to “Disabled”, the mainboard will act “typically”: the processor Vcore will drop down much more dramatically and may even hit the significant 0.08V."

Seems they have fixed that Vdroop issue. What do you think? Apart from this the P5K Delux seems like a fantastic mobo and I just cant wait for it
Any indications what the price might be when they are introduced in here?

I have played with the Asus P5K3 Deluxe, the DDR3 version and i know about Voltage damper thing,it works but then boards from Abit or Gigabyte have almost 0 droop.
Also played with Asus BlitZ Extrem [ROG series P35 board] but that had horrific droop but then it was Q6700,maybe thats the reason for heavy droop. Set 1.725V in BIOS and got 1.61V as real

While P5B Delux is a stunner of an OCing board P4 is'nt, I am not sure which P4 chip you have, if its Northwood its a running nuclear reactor, you would need a very decent cooling sloution before you even think of OCing a northwood chip..........

You are wrong my friend.Northwoods use to run very very cool and it was Prescotts that were infamous for being extremely hot.
Northwoods overclocked very well too.

@sam9s I think you have got it wrong. It is the Prescott that has the heating problem. You can see the same being discussed here too:
*www.thinkdigit.com/forum/archive/index.php/t-18181.html
And unfortunately I do have the Prescott and it runs hot enough to put my Scythe Ninja to shame it idles about 43 and peaks to more than 55 under load(With my cabby always open and with cooler master TIM and a 120mm cabin fan) The mobo around the socket easily heats up to almost 70 and many a times left me wondering if theres a shorting or some other problem with the board.
I made the mistake of buying the Intel mobo and so havent overclocked the Prescott yet. How is its ocing capability?

Thanks. BTW which is the best online shopping site that uses private shipping and has the cheapest shipping costs as well? Now that the rupee value is high I am thinking of buying some items from the US. Last time I shopped at sidewinders and even though their service is excellent they use usps for shipping. In India its not too reliable. I missed collecting my package at local post office on time and it was about to be returned back. Thanks to our front desk in my office and then the wrong info that I was given at the foreign post office that the package was still detained by the customs.

@ Sam,
Dude even i had Northwood chips and my 2.4C used to easily clock to 3.2G with stock cooling with temps in acceptable range.
