Mind sharing your OC settings, im on the standard cooler at the moment but to keep temps down i shut off 2 cores (takes 10c of the max temp) I couldnt get it stable at 3.9ghz though (1075t) it crashed on 10of20 IBT runs with a max temp of 48c. at 1.488v vcore load.
Ar my multiplyer only goes to 15x so i need to be at 266 x15 to hit 4ghz I take it you lowered the multiplyer on the RAM to keep it at 1333mhz?
Yeah had turbo off
Do you also turn of AMD cool n quiet? ( i like the idea that when its idle its only like 1ghz 1.2volts)
