So what does ACC stand for on the mobo?

[CodeForSociety]

And what exactly does it do? Im about to buy a new gaming computer and I have been doing a lot of research and it looks like I can buy a phenom 2 tri core and i could have a chance of unlocking its fourth core. So could someone just give me some background info on this whole ACC mobo thing?

I believe its Advanced Core Calibration. Never tried core unlocking so can't really comment.
