Thought I'd post this screen of a pretty high speed run on this board. It's a wonderful board to work with--very nice recovery qualities on failed overclocks. I imagine the board has quite a little left to go--I only stopped at 610 because my memory tops out at around 612 at 555-2.2v. Of course, the board is being helped along here by an air conditioner (notice the board temps in Smart Guardian). The weird cpu temp is because this was done under the vapo and Smart Guardian won't display sub-zero properly. The only real problem the board has is an incompatibility with my 3870X2. I've also heard of similar problems with the DFI X38-X48 boards and 4870X2's.
