I've had a fun time with this board over the weekend. I went into it not knowing near enough about the board and the settings, but I think I've got a handle on it now.

I did not reinstall Windows 7 x64 and haven't had any issues thus far. peripherals are working fine, disk transfer speeds are right on, and I even was able to move my RAID 0 array from a Gigabyte P45 chipset board. Games are running well (Bad Company 2 rocks now, went from minimum fps of 20 to 80, switched from an e8400 @ 4 ghz).

I am on the 1003 UEFI, the one without the Internal PLL Voltage. I plan to install that later today, especially if my current stress test doesn't work out. Currently I am 40 minutes into a prime95 session running a 2600k @ 4.8 ghz, 1.375 vcore (1.384 showing in CPU-Z), HT off for now, and most of the CPU Power Management options set to the Maximum/Extreme settings, but everything else left enabled (Speedstep, C states, etc). It was crashing when I left the CPU power stuff at Auto, but we're looking good now. I am hoping I can drop some vcore now that I have got my power settings dialed in a little better. Temps are hovering around 70C now.
