Problem OC'ing an i7 960

post #1 of 13
Thread Starter 
Hey all,

I'm having problems with my i7 960, even when overclocking slighty (3.6ghz).

Basically I first had a problem with my 4ghz overclock, after about 45 minutes of prime95 my computer would freeze and i would have to reboot. At first I thought this has to be a RAM or PSU problem, but i tested both and they are working fine.

So I figured I would try testing everything at stock again, I ran prime95 at stock clocks for about 3 hours and everything was fine.

After paying closer attention to CPUID i noticed the the cpu was only getting 83.6 watts under a full load. Now at stock i know it sucks back about 144W, im not sure what step i'm missing, but it goes back to 144W under stock clocks and then back down to 83W when under even the slightest overclock.

I never seem to have this trouble in my lan rig which has a i7 920. I'm hoping maybe you guys know what silly step im missing or if its some other problem

Rig specs in my sig, thank you for your time.

Cpuid power draw number means nothing.

Sounds to me like you either need to bump up the qpi/vtt/uncore voltage a bit or you simply need more vcore

As kevingreenbmx said try upping the voltage abit, if its not too high already.
Freezing usually occurs if it doesnt get enough voltage / or if i gets too much.
Atleast in my experience )

Try a lower qpi voltage.

Also, what is your memory dimm voltage currently?

lower your bus speed up your multiplier.
Just a suggestion.
