I bought an Asus X99-WS IPMI off eBay. It seems to be working great except for one issue... Channel A DIMM doesn't detect properly. From the SPD diagnostics, it would seem that the board knows that a DIMM is there, but it seems to be unusable.

Not working (A1):

Working (B1):

Tried the following;
1) Two different CPU's, E5 Xeon's.
2) Moved the DIMM's around, they all detect properly except when on channel A
3) Used Registered DDR4-2133 1Rx4 and unbuffered DDR4-2133, both Crucial brand.

Any idea/suggestions on how to get it working?
