I toyed with a gigabyte EX58-UD4P and it was much easier to get a 4.2GHz bench stable overclock than the DFI though the bclk topped out at 200MHz. I'm still tweaking the DFI and have yet to break 205 bclk using the 20 multi and 211 using any other.I have benched @ 4.3GHz with though. I'm a little more conservative voltage wise than the people who have though. My one complaint and problem I guess is this board appears to need to have a collation between vdmm and vtt as eva indicated. I'm sure I'll get better clocks once I get that down. This is still a tweakers board and will become easier once more info is available. Eva has been a great help though keep it coming.
