Hi newcomer and welcome to the Tom's hardware forum.
Ur RAM should work without problems in the mobo, but I think that for the 2000MHz u need use the XMP profile or set the specifications of ur RAM manually in the BIOS, but like I say should work at 1600 or 1333
I have put together my system but I am getting status code error 21 (3 beeps) (MEC Memory Detection: MRC entry point)
I noticed a few other people have had this problem with this board when both DIMM 0 slots are populated. I have been able to boot putting both sticks in Channel B.
I have not seen a solution to the problem, any suggestions?
