All 4 SSD's we have a PCIE NVME's. That might be your issue.

Is it the SFF? Just get the OEM board on ebay.

Looking for a board that runs RAID 1 through PCH not VROC. Recently got the Rampage Omega but that didn't work so we returned it.

Just returned our Omega because we can't even run RAID 1 mirror on it. Dimm.2 IS enabled by default if you will be running the SSD's on it independently. The only time you "turn it on" is if you want to run VROC. Just leave everything off and do this, I was able to make 4x970's show up on all M2_1,M2_2,Dimm_1,Dimm_2. We originally wanted RAID 10 For the M.2 devices that is not detected in the BIOS please follow the steps below: Select Boot -> CSM Change Launch CSM to Disable Go to Secure Boot Set OS type to Other OS Under Key Management, Clear Key Boot key Press F10 to save
