Dell PowerEdge R440 upgrades
Check which drive backplane the server was ordered with, since bay count and NVMe support are fixed by it. The BOSS card and IDSDM are proprietary Dell modules, not standard M.2 or SD slots.

DDR4 RDIMM/LRDIMM slots 16 × DDR4 DIMM · up to 1.024 TB total · 2666 MT/s · registered (RDIMM) · ECC
Registered ECC RDIMM or LRDIMM only; UDIMMs and SO-DIMMs are not supported. RDIMMs go up to 32 GB each (512 GB total), and 64 GB LRDIMMs give 1 TB. CPU1 has 10 slots and CPU2 has 6, so a single-CPU system is limited to 10 slots (640 GB max). Mixing speeds or ranks lowers speed.
