Make damn sure you are on 1814 of the MB Bios. the previous ones outright suck.

1) "load optimized defaults" system should run. (reboot)
2) "Turn off things you not use, the simple things"
3) "Turn on HPET" (Windows likes this a lot!!!)
4) "Do not turn on EFI, my op. still broken with USB keyboards)
5) If things work, then turn on XMP profile 1 and reboot.
5.1) make sure the voltage if needed shows as updated, if not then flip to manual mode and all the parms stay the way of profile, but then bump up the volts to what is required for ram.
5.2) if not work, see #6


6) "BUY G.SKILL PC3-1600 7-7-7-18 2X2GB" I run just perfectly at 400(1600) at those timmings and even a tad less than profile #1
