Quick question. Do you think the CPU PLL voltage being 1.5v (lowest) be holding my OC back? Maybe bump up to 1.6v? Before i updated to the 0809 bios, I was able to get to 3.78ghz. Now anything over 3.6ghz is unstable. Would this be the key? Running my q6600 @ 1.5675v was NOT the answer, lol. It used to run at 3.78ghz at 1.5v 24/7 stable.
