Supermicro H11 generation (DDR4, AMD EPYC 7001/7002) — supported memory

Family row, memory support is a per-family envelope and board/revision-dependent. AMD EPYC 7001 series, plus EPYC 7002 with board revision 2.x. Boards checked (H11SSL-i, H11DSi-NT, H11DSU-iN) all list Registered ECC DDR4: 2666 MT/s with EPYC 7001, 3200 MT/s with EPYC 7002 (board rev 2.x required). 8-channel memory bus per CPU; 8 to 32 DIMM sockets depending on board; up to 256 GB per DIMM (rev 2.x); up to 8 TB total on H11DSU-iN rev 2.x (4 TB at 2666). Sources read via Wayback snapshots (supermicro.com blocks fetchers); no LRDIMM support stated on the boards checked.

Confirmed = listed in the vendor's memory documentation for this server. Vendor match = the vendor's own part cross-reference matches the module and its speed is validated for the platform; not taken from this server's memory list. Spec match = meets this platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. How we verify →
