I've wanted to, but I just don't know how. I heard there was some downloadable software that can tweak things a little for you. Anyone know? I've got an AMD X2 4000+ which is 2.1ghz. I heard these are bad for overcloking because the multiplier is locked or something like that. I just want to get it to like 2.4ghz and I'd be pretty satisfied. Any help or am I SOL?
