So I have an Asus p9z68-v pro Motherboard with a 2600K.
I set my system up and installed windows, everything fine. Then, i decided to overclock to 4.5GHz.
Everything still, fine. Ran P95 for 6 Hrs, with temps never exceeding 65 degs.
However, sometimes (not all the time) when cold booting, my PC does not post. It then restarts, and always posts fine.
I thought my OC could be unstable, so reduced to stock speed again, but the problem still persists.
Friends have told me it is a voltage problem, with the CPU not having enough voltage to boot from cold, but is this correct and do you guys have any advice?
NB, my PSU is plentiful-850W (to be on the safe side.)
