My 2.4C is 48c at 12X270 with 1.65vlt under load on my IS7. This is with stock cooling. This is my first Intel build. I'm trying to stay under 50c, and I think this chip will go higher, so I think I need better cooling. Would like to get at least 275 maybe more. Do you think I should stay under 1.7vlt, and if so how much more do you think I may get. My mem is xms 3200 set at 3/2 @ 2.8vlt. Right now I'm just trying to find the FSB ceiling of this chip. THX
