Positive experience with ACC on Phenom II

[mattkosem]

ACC does appear to gain me a little extra stability but in tests so far it has not proved worthwhile. eg.

Up the speed on my 3rd core, from observation this is the weakest, until Prime95 fails. The fail is usually a re-boot at this point. Enable ACC -2. Prime95 still fails but on a rounding error, no reboot. ACC = -4 gives the same result, ACC = -6 and it's back to reboot. Hum, it is doing something, intentional or otherwise.

I'm using +2% on my weak core. -2% seems to make my results worse.

With my Phenom II 940BE and Dfi 790FXB i first need to press reset after enabled acc and then it works to boot in to windows but i lose some stabilty with (acc enabled) becuse i geting blue screen next time i restart windows.

Maybe its the board or the cpu.

Since you didn't mention having one bad core, and didn't mention enabling ACC on it and it alone, it sounds like you're going about trying ACC with the wrong approach. Have you tried OCing core by core, and run into one core that clocks worse than the others?
