I hope someone has seen this before. I have a typical x11ssm-f setup with FreeNAS on bare metal. I recently migrated from my ESXi to a simpler setup. Everything has been rock solid for at least 3 years.
I recently picked up a DC P3700 HHHL card to use as a SLOG. I loaded the card into another machine, booted and used the intel tools to overprovision the drive in preps for use as a SLOG. My problem is that when I insert the SLOG into either PCH slots 4 or 5 (does not matter) on my FreeNAS machine, I mysteriously lose a DIMM slot. Freenas recognizes the new SLOG (I can see it in the drives list in the GUI). Everything else is normal except I only have 1/2 my RAM.
I swapped sticks between slots with no change in results. The only way to gain DIMMB2 back was to remove the SLOG. I am considering moving the ram to other slots, but the supermicro manual says to populate slots in a specific order... B2 being the first one to use, followed by A2. The stick in A2 (either stick) works with the SLOG installed, but B2 does not. If I try to boot with a single stick in B2 with the SLOG also installed, the board will not boot and complains there is no RAM. Remove the SLOG, all is well.
I looked into my BIOS settings and everything I think could make a difference is set to default values. I did try to change a couple settings with no success. I toggled the following BIOS settings (one at a time) from their defaults (all have since been returned to default) in an attempt to resolve. Defaults are in bold:
Here are my specs:
Thank you in advance.

2 x M391A2K43BB1-CPB 16GB DDR4-2133 ECC (populated in B2 and A2 per the manual)

I am hoping someone has seen this, but my search of the board and google has not been helpful.... Thank you in advance.
