Spec match covers every DDR4 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
Is Lenovo 4ZC7A08708 the same module as M393A2K43BB3-CVF?
Yes. Lenovo resells this Samsung module under part number 4ZC7A08708; Dell does the same as AA579532. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Kingston or Micron module instead?
In most servers, yes: KSM29RD8/16HDR (Kingston), KSM29RD8/16MEI (Kingston), MTA18ASF2G72PDZ-2G9 (Micron) match this module on every key specification (16 GB, DDR4-2933, RDIMM, 2Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take M393A2K43BB3-CVF?
Dell PowerEdge C6420, Dell PowerEdge C6520, Dell PowerEdge C6525, Dell PowerEdge FC640, among others, match it through the vendor's own part cross-reference (e.g. Lenovo 4ZC7A08708) with a validated speed. Other DDR4 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
