Spec match covers every DDR5 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 49 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 Supermicro MEM-DR512L-CL01-ER64 the same module as MTC40F2047S1RC64BB1?
Yes. Supermicro resells this Micron module under part number MEM-DR512L-CL01-ER64. 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: KSM64R52BD4-128MB (Kingston), MTC40F2047S1RC64BB1R (Micron), M321RAJA0MB2-CCP (Samsung) match this module on every key specification (128 GB, DDR5-6400, RDIMM, 2Rx4). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take MTC40F2047S1RC64BB1?
Supermicro GrandTwin H13 (AS-2115GT-HNTR), Supermicro H14 generation (DDR5, AMD EPYC 9005 Turin), Supermicro SuperBlade (X14, Intel Xeon 6), Supermicro X14 generation (DDR5, Intel Xeon 6) match it through the vendor's own part cross-reference (e.g. Supermicro MEM-DR512L-CL01-ER64) with a validated speed. Other DDR5 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
