i7-950 @4GHZ And Prime95

post #1 of 21
Thread Starter 
--------------------------------------------------------------------------------

I was running a stress test on my cpu using prime95, it ran for almost 2hours when i noticed that core temp showed the third core at 50 percent, all the rest of the cores were at 100 percent . Anyone have any ideas why core 3 showes 50 percent. thanks average temps during test were 60-65c on each core.

That is odd.
Does it do this after a fresh boot?

unstable overclock, one of threads had an error and stopped. Each core has 2 threads with HT on, so when one errors you are left with 50% load.

If your failing at 20mins, I would bump up vcore 2 notches in bios and try again. Your temps are good.

AliceInChains nailed it - one of your workers stopped. Have a look at the P95 window to confirm.

Up to 1.45000v is safe for a 45nm processor. Just keep an eye on your temperatures.
