Samsung M393A4G43AB3-CWE 32G DDR4 3200 RDIMM
The Samsung M393A4G43AB3-CWE is a 32GB DDR4-3200 ECC registered DIMM built for enterprise servers, virtualization hosts, and cloud or storage platforms. It targets IT resellers, system integrators, and data center procurement teams upgrading or maintaining DDR4-based server fleets. Note that as a registered DDR4 module it can only be used in platforms that support RDIMMs and cannot be mixed with DDR5 or unbuffered desktop memory.

Good to know
- Compatibility: confirm your server platform supports DDR4 RDIMMs at 3200 MT/s — memory generations and buffered/unbuffered types are not interchangeable, and actual operating speed depends on the CPU memory controller and installed population.
- Within Samsung’s DDR4 RDIMM family, this dual-rank 2Rx8 32GB module occupies the mainstream capacity tier for virtualization and cache-tier workloads, offering a practical balance between channel density and per-module capacity.
- Buying tip: when populating multiple channels, keep module capacity, rank count, and speed grade consistent across channels to avoid falling back to lower common data rates — order matching kits for multi-module upgrades.
