I recently put together a new rig, i picked the AMD 4000+ San Diego for my cpu and the abit fata1ty as my mobo... when i went into my bios it said my cpu was running at 2.2ghz which is below stock speed... im guessing this is just some default that mobos use, but i was wondering what i should set my voltage to so that i can run it stock at 2.4ghz?
