The guides are good here lotta folks in the know . I have an 240 reger w/ stock cooler stable 24hrs prime 95 at 3.2 ghz FSB setting is 234 mhz all other settings stock .
Make sure you get Core temp here
and watch it max temp for a 240 is 70C under load prime 95 or so normal use on a hot day 40-58C avg 50C summer keep your normal oporating temp below. 60C~ I coulden't get mine stable on stock cooler much above 3.2 YMMV. Old thread nobody's posting there currently but good info there.
with voltage and memory settings changes some here are getting them quite a bit faster. check out the official 240 overclockers club thread here
