Please ignore my horrible wire management, I'm still learning. (I zip tied the wire touching the graphics card after I noticed it in this picture)
While showing this I also had a question, while installing the ram in this mobo the directions said to use DIMM A1, B1, C1, and D1, but the only way I could get the bios to recognize it was to put them in A1, A2, C1, and C2, any idea?
Probably going to get another SSD to throw in here too.
Did you update the BIOS to the latest release yet? Make sure you're running with the latest version to ensure this isn't the reason for your RAM issue. Otherwise, you'll continue running dual-channel rather than quad-channel.
If you update the BIOS and find you're still having the issue with the board recognizing all the RAM you have in the appropriate spots (A1, B1, C1, D1), then I'd start the RMA process for the motherboard.
