I have EIST off, turbo boost off, Power Technology off, C1E off and Overspeed Protection off. I ran Prime95 and it stays at 3.3ghz. I am confused. Thanks
Well, that's your problem. When overclocking a 2500K, you modify the turbo multipliers, not the base ones - the base ones are locked, the turbo ones are unlocked. Turn back on Turbo! Oh, and I'd recommend turning back on all the things you turned off, while you're at it.
