At work we have 5 systems with identical mother boards (Supermicro).
When I was upgrading to 64GB, 4 or the systems would use the 4GB
memories (after flashing a new BIOS), but 1 system was stuck with 1GB
sticks. We just decided to leave it at 16GB. Note that the memories I
used were listed on the SuperMicro site for compatibility.

The one issue with Rich's system are that the memories are 2 different
speeds. What if Rich reversed the order of the memories.
