I'm not using the latest BIOS just released, but the one prior to that. It's stable at 3.0Ghz with stock voltage (this board overvolts though), and I could POST at higher frequencies like 3.3Ghz, but I had to push voltage beyond 1.4V, which I'm not comfortable with. I'm also using 8 gigs of RAM, so I think that may also factor into my overclock. The board also takes an 8800GT without any issues. I've got an itchy trigger-finger to get a Phenom, but something tells me I'll probably have to pick up a Gigabyte board in order to use one.
