I just purchased this board two weeks ago. I currently am running it in ACHI mode with a WD Blue 500Gig boot drive and a 2Tb Hitachi drive for storage. I just stumbled over the fact the board does simply not like to Hibernate. Has anyone else had this problem with this board or another type of board similar? Other tidbits are its running a Phenom II 955 C3 stepping, 4G x2 of Crucial DDR3 1333 at standard timings, and a ASUS DirectCU GTX460 all powered by a Corsair TX750.
