A friend of mine is running a Core2Extreme on Stock, but the speeds done seem to be right. Looking at CPU-Z, it's clocking at under 1Ghz.

Specs:
asrock p45de
CPU FAN Zalman CNPS9500A-LED Aero Flower Socket 1156/775/AM2+/AM3/754/939/940 Cooler
PSU:Corsair TX750
He's overclocked it to 3.2gh'z but I think there is more there:
Temps:
Any idea as to why this is not running at the speeds it should be, is the BIOS setup incorrectly. I've not seen the actual setup, we've just chatted about it over FarCry 3.
