Hi!
I have the ASUS X99-A II (Link) mainboard only recognizing two RAM modules at the time. Here is the relevant hardware:
Mainboard: ASUS X99-A II (Link)
RAM: HyperX Fury (4x, 8GB, DDR4-2133, DIMM 288) (Link)
CPU: Intel Core i7 6850K
PSU: Corsair RM550x
I list the PSU because I can't connect the EATX12V_2 (4Pin) port because there is neither a an additional cable for it available nor would I have a free connector on the PSU to connect it to if I had one.
Settings: XMP is on, system is not overclocked yet. Newest BIOS is flashed.
The problem: If I connect all 4 RAM modules, the BIOS only recognizes the 2 connected in C1 and D1. Other configs are:
The RAMs are listed in the QVL. The manual says though, that 16GB is the maximum for non ECC RAM.
So, if I were to return my 4x8 and get some 4x4 or ECC 4x8, would the MB recognize all the RAM? Do I need another PSU so I can connect the 3rd power plug? Am I doing something else wrong?
Thanks!

- Inserted: C1 + D1 = Only D1 recognized
- Inserted: (A1 or B1) + D1 = Only D1 recognized
- Inserted: All 4 = C1 and D1.
