Easiest way don't exist...oc is long process...every time put a 1Mhz up in bios and start up again the system...if the system don't crash it's ok...but then look in everest or some other program if the processor is stabile...if it's not stabile put up the voltage in bios (if you have that option)...standard voltage for processor is 1.65V, you put it on 1.7V...restart...get in windows, look if stabile, run some aplication or get in the game for 10 minutes and look the temp. of processor...restart computer and start the process again until system crashes down (if you want go that far)...when system crash you now it's enough...then restart system and put the fsb few Mhz down...if not remove the bios battery and everything do again...don't go too far with OC (it's my advice)...
Sorry about the grammar.
