Same issue with this board as my old board. When the PC is shut down for a longer period of time (~8hrs) upon boot tells me "Overclocks failed" and reverts the memory to 1333mhz and i have to log in BIOS, save and exit and than it boots up fine with the proper settings(2133mhz). Annoying as hell. Looks like im gonna have to hunt for some P67 certified memories. Sad cause these G.Skills are running perfectly fine when the mobo decides to boot up properly with them.
