When I turned on ACC, Core Temp refused to display any other temp than 0°C with a question mark. Even if Core Temp doesn't work, what should I set ACC to? I heard ACC allows for higher overclocks.
AMD ACC + CoreTemp incompatibility

OK it is disabled. I've heard that ACC also helps squeeze 200 to 400MHz more out of an OC. How it works and what settings you use are pretty mystical, though. Not even users on the AMD forums have an idea what to set it to.

Well I would guess that google would help there, but all I know is that three boards I used on that socket with those CPUs did not have it and, it was put there to unlock cores to entice you into buying those boards.. (one of which was a Asus M3A32 wifi AP and allowed me to get the 940 to 3.9ghz stable on an NH-D14)
Asrock use it on some, Nvidia put it (under their naming of NCC or something, UCC maybe?) on their last mobo ever, and it was put there soley to unlock cores.

I think that was from the AM2+ days. ACC is now implemented in on-die instead of on the motherboard. I know ACC allowed for higher OC's back then. Don't know about now though.

I'm pretty sure Asrock are still using it now tbh. You are probably right, especially if they're putting it on die.
Although maybe that's how they always saw all of the cores? by having it on chips that say, used all four, and not having it on a chip that didn't?
I'm not sure if Intel use the same chips and then lock cores tbh. I know well that AMD do for pretty much all of their CPUs. Sometimes because cores failed, sometimes just to make the numbers on the lower cost chips (which is the ones you are looking for for unlocking).
Dunno. I shall do more research

Kinda sure I know what it does now. I found it at [url="http://www.overclock.net/amd-...179-amd-advanced-clock-calibration-guide.html[/url]. They said higher the percentage (up to +12% = higher overclocking),lower the percentage, lower the percentage (down to -12% = more power efficiency). Can't confirm it though, as AMD has never explained it.

I found out that enabling ACC, regardless of % setting, allows more options in AMD OverDrive, like IGP overclocking.
