Genuine Samsung memory modules — original Samsung product, not equivalents. When a server's QVL names a specific Samsung part, when a warranty or procurement spec requires the OEM module, or when you're matching modules already installed, this is the page.
All Samsung part numbers across every module family: M393 and M392 registered RDIMM, M386 load-reduced LRDIMM, M391 ECC UDIMM, M378 non-ECC UDIMM, M471 SODIMM and M474 ECC SODIMM, plus the M321/M323/M425 DDR5 lines. Densities from 1GB to 256GB, in every rank configuration from 1Rx16 to 8Rx4.
DDR3 is the largest block at 357 listings — deeper than almost anyone still carries. A great deal of enterprise hardware from that era is still in production, and finding original Samsung modules for it has become the hard part. DDR4 accounts for 222, with DDR5 growing.
Samsung's part numbers encode the full specification — M393A4K40DB3-CWE is a 32GB DDR4-3200 registered module — so if you have a code off a module label or a memory report, search this page by it for an exact match.
