It appears there might be a core parking issue with the UD3R motherboards as the CPU speeds go over 2.6-2.8GHz. There are so many posts out there regarding the UD3R and this issue, and I've seen so many other boards with these exact settings enabled without issue with I5 and I7 CPUs that I have to assume Gigabyte just has a problem BIOS for this board around memory management and CPU or bus speed. If disabling the C3/C6 state support "fixes" it, you're basically disabling core parking. I'm not sure you can have core parking during boot, and my guess is that it's happening - would love to see one of these under a kernel debugger when it panics and reboots though to be sure.
