Samsung M393A2K40EB3-CWEC0 16GB DDR4-3200MT RDIMM
The Samsung M393A2K40EB3-CWE is a 16GB DDR4-3200 registered ECC DIMM (RDIMM) built for server platforms, data centers, and virtualization or HPC workloads. Its registered architecture with onboard ECC makes it suitable for multi-DIMM population in dual-socket hosts where signal integrity and uptime matter. Note that DDR4 RDIMMs cannot be mixed with DDR5 modules, so confirm your platform generation before ordering.

Good to know
- Compatibility: This is a DDR4 RDIMM and will not work in DDR5 platforms or mix with UDIMM/LRDIMM modules in the same channel — verify your server’s qualified memory list (QVL) and CPU memory controller support (3200 MT/s operation may be downclocked depending on CPU generation and DIMM population).
- Within the Samsung DDR4 RDIMM family, the single-rank 1Rx4 16GB configuration offers a good balance of per-channel bandwidth and cost efficiency, though dual-rank 2Rx4 variants of the same capacity may perform better in bandwidth-sensitive workloads.
- Buying tip: For dual-socket virtualization or cache-tier hosts, populate channels evenly with identical modules (model, rank, capacity) to maximize multi-channel bandwidth and avoid POST/training issues.
