Just wrapped up a review on this board, I like it a lot. 229bclk through SPi 1M, 227bclk through SPi 32M and IntelBurnTest looped 5 times. I was using the F4 BIOS on my w3570 with 1.35vcore, 1.30vtt, 1.65vdimm, and 111MHz PCIe. I think I really only needed around 108MHz PCIe but I've been using 111MHz PCIe since the Classified launch

Going to play with the board subzero a bit later this week but I'm really saving it for Gulftown. I figure the board should handle gulftown rather nicely, it sure has enough caps and fets/chokes.
