Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 91 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.
