HPE ProLiant Compute ML350 Gen12 upgrades

Model-dependent chassis. The QuickSpecs also list 12 EDSFF NVMe bays and a 2x960 GB M.2 NVMe RAID1 boot option (NS204i-u), but the sources give no M.2 lengths, so they are not listed as slots. Check the QuickSpecs for the exact model.

DDR5 RDIMM slots 32 × DDR5 DIMM · up to 8.192 TB total · 6400 MT/s · registered (RDIMM) · ECC

16 slots per CPU, so a single-CPU build only has 16 usable. 6400 MT/s needs 1 DIMM per channel; 2 DIMMs per channel (the 8 TB maximum) runs at 5200 MT/s. HPE Smart Memory RDIMMs only; unbuffered or non-ECC modules are not listed.

LFF 3.5" hot-plug bays 12 × HDD / SSD 3.5" (SAS / SATA) · up to 26 TB

Bay type and count depend on the chassis and backplane model. SSD maximum in these bays is listed as 960 GB drives. A storage controller is needed.
