I recently upgraded to a buddys old EVGA x58 setup that has 6 gigs of corsair 1333 ram and an i7 940. I want to OC this guy, but my extent of OC'ing has been my old Q6600 rig. Can the 940 hit the 4Ghz barrier? Also, what cooler would be good for this setup (Keep in mind I have a Lanboy Air case). And what settings should I change/use to hit this barrier?
