just make sure you have the latest BIOS with this board... i've had this board since it's release.. was buggy, would BSOD every couple of days, also have three 7970 gpus and 3930k... but with the latest bios it's been rocksolid... SSD caching didn't work to will for me and so i'm just running the OS off a M4 256gb ssd.
don't know much about the rampage though. hope this helps.
