Raise the fsb in small steps cos all busses in da pc are tied to it I.E. pci,usb,RAM.... easy enuff.... get good quality ram if you can cos the cheap stuff usally dosnt like higher speeds than whats its rated at...... this is also why ocing thru the multiplyer is best (amd's only) cos it allows you to raise you cpu speed and still keep your other busses @ stock speeds....and i havent even talked about cooling...
cheers
