I overclocked my processor from 2.66 to 3.1Ghz by raising the Blk from 133 to 155. It was pretty much stable as a rock. Idle temperatures around 37-43. Full load around 70. At first I thought the idle temperatures were not low enough (been reading people get like 25-30c idle temps ) but figured these numbers are good enough. Turning hyperthreading off made no difference in idle temps but did drop the temps under load from 70 to 60.
Anyways, I tried raising the Blk further to 158 but the computer did not boot up successfully. Blank screen. Reduced the Blk to 156 and it booted up fine. Idle temps were pretty much the same. However 3 minutes into prime95 my computer froze. No blue screen or anything just everything froze. I have reduced the blk back down to 155 for now.
What changes do you think I need to make in order to raise my overclock? I have pretty much left every setting in bios other than the blk to auto and was unsure if I need to tweak voltage values.
Any help would be appreciated.
