Which games are we talking about ? have you enabled Vsync for these games and locked PCI express frequency at 100 or 101 ?

Well after close to a month tweaking this thing I give up... Can't break 4gig for the life of me Just don't know if it is board or the CPU (E8400 E0) that is dud :/ Memory oc like crazy but no use for that

Board desing it is not, as 500FSB daily is really nothing. Either you got a bad or unlucky board or something else is terribly wrong... did you already fill in a template ? and plz list all of ya hardware... 4ghz with a wolfdale should be absolutely no problem
