I'm currently running my i7 950 with ht enabled at 20x205 with 1.3v and after running prime95 for about 3min my comp crashes. i have the h50 and it goes from about 73c-85c and then crashes. I've tried many different voltage settings but it still crashes? anyone know why its not stable?
its very differcult to get past 4Ghz with a cor i7 9xx CPU, you need to do alot of research and tweaking.
Do you have hperthreading (HT) or Turbo boost on?
I would recommend some voltages to try but to be honest your at your CPU's temp limit really, I wouldn't recommend you overclock/overvolt further.
To regain stability lower your multi or blck value.
