I think it is a matter of stabilizing my CPU with higher voltage. But since I am not very familiar with C2D CPU yet, I am a bit hesitate.... What is the safe limit that I should never exceed on this E8500? I heard it is about 1.45v for us average people, but it is the value taken in CPU-Z or set in BIOS?
Recommended not to go over 1.40v, 1.42 would be the absolute maximum if you need those extra two for stability but no more than that.

I try to keep mines at 1.39-1.40
