I am in QUAD channel memory mode and can currently only detect 98 of 128GB of my RAM, due to RAM not being detectable in DIMMs C2 and C1.

What I have tried:

I have tried moving around the RAM to verify that it was not the RAM sticks that were defective, and noticed that DIMMS C2 and C1 never detect RAM.

I have tried updating the BIOS to the latest version.

I have tried two sets of 8 by 16GB sticks (Vengeance and Dominator Plat, both at 2666MHz).


Please let me know of anything else to try, or if I should just RMA the MOBO.
