Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 67 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.

Frequently asked
Is HPE P00920-B21 the same module as M393A2K40CB2-CVF?
Yes. HPE resells this Samsung module under part number P00920-B21; Lenovo does the same as 01KR353, Lenovo does the same as 4ZC7A08707. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Micron or Samsung module instead?
In most servers, yes: MTA18ASF2G72PZ-2G9 (Micron), M393A2K40DB2-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.
What servers take M393A2K40CB2-CVF?
HPE ProLiant BL460c Gen10, HPE ProLiant DL160 Gen10, HPE ProLiant DL180 Gen10, HPE ProLiant DL345 Gen10 Plus, among others, match it through the vendor's own part cross-reference (e.g. HPE P00920-B21) with a validated speed. Other DDR4 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
