Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 99 further platforms also match this module on spec. A server missing from this table is not a compatibility limit. Browse all servers →
Confirmed = listed in the vendor's memory documentation for that server. Vendor match = the vendor's own part cross-reference matches this module and its speed is validated for the platform; the module is not taken from that server's memory list. Spec match = this module meets the platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. Confirm against your server's qualified parts list before ordering.

Interchangeability is based on matching JEDEC specifications, not per-server testing. Confirm against your server vendor's qualified parts list. View the full family →
Frequently asked
Can I use a Micron or Samsung module instead?
In most servers, yes: MTA18ASF2G72PZ-2G9 (Micron), M393A2K40CB2-CVF (Samsung), HMA82GR7CJR4N-WM (SK hynix) match this module on every key specification (16 GB, DDR4-2933, RDIMM, 1Rx4). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
