anyway i was folding with 2 smp clients and when i got up this morning the pc had crashed, but when it crashes it doesnt just restart , it kinda just hangs and my gpu fan revs flat out until i push the restart button,

anyone else getting that when it crashes ?

and why is it crashing after 21 hours of prime small ftt, i also ran memtest86 ver 2.10 to test memory and that was ok
Hey Freshy ..

I think you were onto something with these settings ..

I used exactly these settings & been priming for 90mins + now which is farthest I've ever got at at 4Ghz CPU clock .. lowest temps too ..

But I'm confused about your Vcore .. your later posts here are saying you had to up the Vcore to ~1.39V after BIOS updates ..

But then the link in your sig to 4Ghz settings show Vcore of only 1.328V (CPU-Z) .. back on 12-10-2008 ..

So what were you using for that test ? QPI/Vtt volts etc ?
