Overclock causing system instability?

With my offset set to .005 my machine was unable to post.

Was that + .005 or -.005?

+ .005

Increase by .005 until it will boot up and you can check your voltage. Next will be +.010.

It booted with +.010, now my voltage is between 1.1-.1.3V idle, 1.33-1.4V load.

It should be pretty consistent under load.....mine is 1.232-1.240 while stress testing. Wait 5 minutes after you boot up to get your idle voltage readings, that way all services are started and the computer usage should be near 0%. Then fire up Prime95, and CPU-Z(if that is what you use to check your voltage) and let it run for a few minutes and see if your voltage is more consistent. It should not vary from 1.33-1.4V.

Do you remember any other settings you DID change during your original OC? Or did you just turn the multiplier up and roll with it?

Ive been runing prime 95 for about an hour now and the load voltage appears to have steadied out to 1.344V, sometimes is goes to 1.333. And the only settings I changed originally were the multiplier and voltage.

Is it safe to let my temperatures run kind of high while I do the 24 hour prime 95 test? For some reason my middle 2 cores (especially core #2) are running a lot hotter than the other two cores.

What are your temps, and what are you using to monitor them?

I'm using realtemp to monitor them, and they usally sit 65-70,75-80,75-80,65-70 but the middle two can go up to 90 during the more rigorous P95 threads
