AMDs don’t do / require hyperthreading, you get four real cores in a X4.
Hyperthreading is an intel feature.
If you have good motherboard you should be able to overclock your chip though.
I’m running a FX 8 core and have it comfortably clocked from 3.6 to 4.2ghz.
I used to run my Phenom X4 3.2 at around 3.8ghz.
The main board is an ASUS M4A89GTD Pro ( =O ) and says I can over-clock it, boost it, and hit
the Turbo key, so will see how fast I can get it to go, though I doubt it would come close to Garstor’s new smokin’ screamer.
