Hi, im new to all this oc and i like to learn some tips, if ppl will give there time and opion be awsome. Right now my system specs are.

x2 3800-2.5ghz
Mb- A8N-SLI deluxe
Ram- 1gig ddr 400 kingston hyper Dc
Video-2-egate 7600gs in sli mode

the main question is what should i have the volt for the cpu set at and how high can the 3800 be clocked at for a stable system. I ran 3dmark 06 and on the cp test i didnt even get 1 fps why is this? do i need to up cpu volts? Any help would be awsome. Thanks in advance to those that help me.

I have the same setup as you.i was able to push mine to 2.8ghz could run memtest and superpi but for some reason it failed on 3dmark so i went back to 2.6 wich is the best speed

fsb 260
multi 10
vcore 1.5
mem volt 2.65
htt x3

hope that helps..

Well, 2.5GHz is not bad as is. Can you go higher, probably yes but if you want a stable system not much over 2.6 or 2.7GHz.
The effectiveness of your CPU/System cooling will factor into how fast you OC and how high you raise the VCC. I personally would stop at or short of 1.5v VCC. As for testing for stability I personally think Prime95 running on both cores (SML FFT and Blended) is the best way to tell. I’ve read an OC test from Anandtech on the X2 +3800 that they had a problem running 3D Mark 05 after a certain point while OCing. Sounds like the same thing. If you can run P95 on both cores for 8hrs, your system is stable.

As far as the 3dMark06 result, I feel your pain. As a matter of fact, the first time I ran it on my 3800 X2 was last night and I was blown away with the 1fps on the CPU test.

The vCore thing. Get your clock speed where you want it and run Prime or something for a long time to stress it hard. If it's stable, drop your vcore. Keep doing this until you find that spot where you get your stable-ness and your lack-of-heat-ness.

btw - my 3800 X2 is at 2.65ghz and 1.3850 vcore
