I have an asrock z77 Pro4-M and bought some Corsair vengeance pro ddr3 1866mhz 16 gig(2x8). I cannot get pc to post, I get 4 short beeps. PC works fine with Kingston hyperx. I can't enable xmp unless I use hyperx ram to get into eufi. All appears to be compatible that I could determine. Eufi is latest version. Am I missing anything simple?
