I am running the 302 beta bios with a Xeon X3210 G0 and this thing is great. It runs 3.0GHz (kinda like the QX6850 at stock aye?) at 1.25vcore with 3-3-3-12 timings. 3.6GHz with 1.42vcore at 4-4-4-12 timings and 3.8GHz at 1.53vcore with 4-4-4-12 timings. So far I have had no problems with this Premium board.
