OEM cross-references are compiled from distributor cross-reference data and OEM documentation. Verify against your vendor's parts list before ordering.
Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 95 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-DR480L-SL02-ER26 the same module as M393A1G40EB2-CTD?
Yes. Supermicro resells this Samsung module under part number MEM-DR480L-SL02-ER26. The physical module is identical: OEM part numbers are branding, not different hardware.
What servers take M393A1G40EB2-CTD?
Supermicro H11 generation (DDR4, AMD EPYC 7001/7002), Supermicro SuperBlade (X11, Xeon Scalable 1st/2nd gen), Supermicro X11 generation (DDR4, Xeon Scalable), Supermicro X12 generation (DDR4, Xeon Scalable 3rd gen) match it through the vendor's own part cross-reference (e.g. Supermicro MEM-DR480L-SL02-ER26) with a validated speed. Other DDR4 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
