Spec match covers every DDR5 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 53 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.

Modules match on all key specifications (type, form factor, capacity, speed, rank organization) and are generally interchangeable in servers that accept this spec. 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 Kingston or Micron module instead?
In most servers, yes: 9965791-046.A00G (Kingston), 9965791-113.A00G (Kingston), 9995791-014.A00G (Kingston) match this module on every key specification (32 GB, DDR5-5600, RDIMM, 2Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
