My understanding about ACC, and it's a very limited understanding, is that in addition to providing a means for unlocking cores on x2 and x3 chips, it also provides a means for 'balancing' out the variances in each core, to provide stability at high o/c's. I read posts all over about people setting one core to 0, another to +2, etc... to gain stability in high stress situations with higher than average o/c's.
Mind you, I'm not referring to posts about the 965, but as I said in the previous post above, it seemed it was making the clock to 4.0 a bit easier for me when I enabled it to +2 on all cores for that short time I had it going.
One thing about it, though, is that I lost the ability to track the core temp with it enabled, I was only able to track the cpu temp. But, when I had it enabled at +2, it seemed the temps dropped about 4-6c (maybe a misreading, I don't know).
Any comments would be appreciated. I'm not so sure it isn't helpful with the 9x5's.
Also, any suggestions on what bios version to use right now for this board?
