hi ive just replaced my e6600 with a q6700 quad core ,i overclocked my e6600 quite comfortably to 3.5ghz but settled off at a round 3.0ghz with 4 gb ram , ive got a bgf 680isli motherboard and ive just installed the the q6700 and loaded the defaults in the bios so everything is running normal speed , now all im asking is for a few pointers from anyone who has had this chip and overclocked it ! whats a decent overclock for this chip without stressing it too much ! what voltage etc ........look forward to hearing from you !
