The Samsung M393A4G43AB3-CWE is a 32GB DDR4-3200 ECC registered DIMM supplied through our B2B channel for wholesale buyers, system integrators, and IT procurement teams maintaining or expanding DDR4-based server fleets. Because this is a registered module, deployment is limited to platforms that support RDIMMs; it is not interchangeable with DDR5 or unbuffered desktop memory.
We carry this SKU in continuous stock with batch-consistent inventory: orders within the same procurement cycle are fulfilled from the same manufacturing lot wherever possible, which matters for integrators standardizing memory across racks. Full certification documentation covering CE, FCC, and RoHS requirements is available on request to support import and export compliance in destination markets.

Good to know for B2B buyers
- Platform validation: verify that target servers support DDR4 RDIMMs at 3200 MT/s. Buffered and unbuffered memory types are not cross-compatible, and effective data rate depends on the CPU memory controller and populated configuration.
- Deployment planning: within Samsung’s DDR4 RDIMM lineup, this dual-rank 2Rx8 32GB module sits in the mainstream capacity tier, well suited to virtualization hosts and cache-tier storage nodes where channel density and per-module capacity must be balanced.
- Consistency across channels: when filling multiple memory channels, keep capacity, rank count, and speed grade identical throughout to avoid downclocking to a lower common rate. We recommend ordering matching quantities per batch for multi-module rollouts.
