Well, so far my experience with the ASUS M3A78-T has been pretty much pants. ACC offers me no improvement over no ACC. I'm still not stable above 2800MHz no matter where I adjust ACC to. I do like how this board's bios doesn't have to be cleared before each boot though. That's an improvement over my K9A2, but of course I still don't have all the fancy add-in cards on this board yet.

What ACC has shown me so far is that it doesn't seem to do jack for helping OC. It just seems to prevent crashes due to "clock interrupt not received" bull without actually decreasing the frequency of computational errors. At 2.9GHz I don't instacrash but it's only like 5 seconds Prime stable until I jack the voltage above 1.425V. Then, it's only stable for a few minutes. It doesn't just crash like on my old board, but rounding errors spoil the usefulness.

Anyway, my review so far would be as described below.

Pick one of the following:
- Well, I guess my CPU is just a bona fide lemon.
- ACC reduces total system failure but doesn't really help computationally stable overclocks.
- ASUS's current BIOS is still just immature.
- ASUS's M3A78-T has an absolute pants implementation of ACC.
