u OC in bios or use utility?

if OC in bios do dis:

1) RAM timing set to auto.
2) in crease ur fsb bit by bit (5 or 10 each time), only increase ur fsb if it passes the POST, means can boot.
3) once u can't boot anymore, increase ur vcore by bit (+0.2), den try again.
4) repeat till u get the speed u wanted.
5) go in windows & run IntelBurn test for 3 - 5 round (monitor ur temp, stop if go above 90).
6) if test successful, congrat, u got a stable OC.

if OC wit utility, its very ez, just set ur fsb, multiplier & vcore, also increase.
but OC in windows might not b as stable due 2 RAM timing & it also doesn't need 2 pass the POST.
