I have the sabertooth 990fx so when I activate ACC, I put it on manual mode so i can keep it at dual core. I currently have my processor clocked in at 4.3ghz now and it has bsod once yet. So Im thinking That if you turn ACC on but keep the extra cores off you can ovc a little more.
hmm interesting fluke. Yea. I can activate my cores individually to. just no reason not to run it as a quad
