one of my 2*1G g.skill 6400hz was dead with this board after 6 months oc use at 1200hz with 2.3v. I do put ocz ram cooler on the pair but unfortu...i do believe that this board has oced vol supply to the ram. If 2.3v showing in bios, it could be 2.4 or 2.45 in reality according to some articles reality testing.
