OverClocking Asus P5WD2-E Premium & Intel D 805

Hi,

Like a lot of people, I got all exited after reading the following
article from tom's hardware:

http://www.tomshardware.com/2006/05/10/dual_41_ghz_cores/

I was about to buy a new computer when I read that article. So I
decided to buy about the same computer they used to make this article.

Asus P5WD2-E Premium
Intel Pentium D 805
OCZ DDR PC-4000 500MHz 2x512MB Dual Channel / Platinum Edition
COOLERMASTER REAL POWER 450W ATX 12V
ATI X850 XT Platinum Edition
2 X 250 GB Western Digital 16MB (RAID0)

And for the cooling I bough the nice Zalman RESERATOR 1 Plus.

So after building the computer I started by testing the stability of
the system at the default settings. It running very smooth and without
any problem even after 5 3DMark runs and a full night of torture test
from prime95.

So I started overclocking. I used prime95, PCProbe from asus and 3dmark
the newest version.

So finally, I realized that Reserator 1 plus is not as great as it
look. At 200 MHz 4.00 GHz the CPU temperature was at 95 C during the
3Dmark and the application crashed during the CPU test. With that
temperature, raising the VCORE voltage is not an option to gain
stability.

I tried at 190 MHz 3.80 GHz and the problem was still the same...

I then tried at 180 MHz 3.60 GHz. The temperature was not a problem
anymore at that frequency. But during the 3DMark, it was still crashing


at the CPU test. I decided to raise the VCORE voltage notch by notch.
But that did make any difference. The default VCORE for this CPU is
1.3375. I raised the VCORE up to 1.5 and it was still crashing. I then
tried to raise the Memory voltage. The default voltage for the memory
is 1.8. I tried up to 1.9 and it was still crashing.

So I decided to try at 170 MHz 3.40 GHz. It was still crashing during
the 3DMark test. I tried the same procedure with the Voltage once again

at that frequency. But the results were the same...

The system look very unstable to me...

But all the hardware I got in that box is recommended for high OC.

If anyone has any suggestion, I would strongly appreciate it.

Thanks in advance.
