Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 94 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-DR412L-HL01-ER32 the same module as HMABAGR7A2R4N-XS?
Yes. Supermicro resells this SK hynix module under part number MEM-DR412L-HL01-ER32. 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: MTA36ASF16G72PZ-3G2R1TI (Micron), M393AAG40M32-CAE (Samsung), M393AAG40M32-CAECO (Samsung) match this module on every key specification (128 GB, DDR4-3200, RDIMM, 4Rx4). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take HMABAGR7A2R4N-XS?
Supermicro H11 generation (DDR4, AMD EPYC 7001/7002), Supermicro H12 generation (DDR4, AMD EPYC 7002/7003), Supermicro SuperBlade (H12, AMD EPYC 7002/7003), Supermicro SuperBlade (X12, Xeon Scalable 3rd gen), among others, match it through the vendor's own part cross-reference (e.g. Supermicro MEM-DR412L-HL01-ER32) with a validated speed. Other DDR4 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
