Overclocking this motherboard, on the CPU side of things, was pretty easy. Choose multiplier and voltage and you're done. Memory, on the other hand, was a bit more difficult. Getting 3200 MHz out of this board shortly after the launch wasn't easy, and you needed some magical RAM to get there. The board doesn't even support memory speeds that high, so there's obvious a reason for why the support stops at 2933 MHz; once you try to push further it just doesn't want to. Now that it has been some time and the fabled May BIOS updates have come and gone, not much is different; however, it can get 3200 MHz stable from time to time. It's weird, really, as it does work on one boot and doesn't on the next. Then there are those times where it will seem like it's working only to let go several hours later. Seems ASRock knew what they were doing when they gave this board the "low" memory speed support.
You do of course get the aforementioned POST display, as the singular "overclocking" feature, although these days, I'd almost call it a prerequisite.
