Was having all kinds of issues with this board, returned to my trusty old eVGA 680i, i love this board (680i) anyway i was getting BSOD's left and right, fresh install of windows, vista and XP both issues, prime95 would crash not even faile, even on stock settings, a buddy of mine working for intel's tech department told me to stay away from the P35, they said it is having so many issues, the chip is wrong in many ways, not in terms of OCing, anyway i didnt listen took a shot and it was a mistake so i returned the board, good luck to everyone else.
