OEM cross-references are compiled from distributor cross-reference data and OEM documentation. Verify against your vendor's parts list before ordering.
Spec match covers every DDR5 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 25 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.
Compatible alternatives any brand · same JEDEC specification
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
Is HPE P62605-B21 the same module as HMCT04MEERA137N?
Yes. HPE resells this SK hynix module under part number P62605-B21; Dell does the same as AC517142. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Samsung or SK hynix module instead?
In most servers, yes: M321RAGA0B20-CWK (Samsung), M321RAGA0B20-CWKZH (Samsung), HMCT04MEERA (SK hynix) match this module on every key specification (128 GB, DDR5-4800, RDIMM, 4Rx4). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take HMCT04MEERA137N?
Dell PowerEdge C6615, Dell PowerEdge C6620, Dell PowerEdge MX760c, Dell PowerEdge R660, among others, match it through the vendor's own part cross-reference (e.g. HPE P62605-B21) with a validated speed. Other DDR5 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
