Samsung M393A2K43EB3-CWE 16G DDR4 3200 RDIMM
The Samsung M393A2K43EB3-CWE is a 16GB DDR4-3200 registered ECC memory module built for enterprise servers and data center platforms. It suits system integrators, resellers, and IT departments provisioning virtualization hosts or cache-tier workloads where error correction and stable registered operation are required. Note that RDIMMs must be deployed in compatible server platforms and cannot be mixed with unbuffered desktop memory or other DDR generations on the same board.

Good to know
- Compatibility: verify your server platform supports DDR4 RDIMMs at 3200 MT/s — some CPU and motherboard combinations downclock the module (e.g., depending on populated DIMM slots per channel). DDR4 RDIMMs are not interchangeable with DDR5 or LRDIMM modules.
- Family positioning: as a dual-rank (2Rx8) RDIMM, it balances density and signal integrity; within Samsung’s DDR4 server line, it targets mainstream enterprise capacity points rather than maximum-density configurations.
- Buying tip: for multi-channel population, source modules with identical part numbers and rank configuration to help ensure stable operation at rated speed; confirm slot population rules in your server’s documentation before mixing capacities.
