With the new memory installed, only half was usable because one DIMM was not working.

I re-seated and swapped things around, same problem.

I installed the old memory, same problem (says it's the same slots failing).

This suggests one or two of the memory riser boards has failed or I broke them.

I have several spares (from the T3-2) that I think will work and will try them tomorrow.
