Samsung M321R2GA3EB0-CWM 16G DDR5 5600 RDIMM
The Samsung M321R2GA3EB0-CWM is a 16GB DDR5-5600 registered ECC DIMM built for enterprise servers, cloud computing platforms, workstations, and data center deployments. It suits buyers provisioning or extending DDR5-generation server platforms where memory bandwidth, error correction, and 24/7 reliability are required. As an RDIMM, it must be installed in platforms that explicitly support registered DDR5 memory — verify your motherboard or server QVL before ordering.
Key specifications (table)
| Parameter | Specification |
|---|---|

Good to know
- DDR5 RDIMMs are not backward or forward compatible: they cannot be mixed with DDR4 modules or used in consumer desktop UDIMM slots, and DDR5 platforms typically require balanced channel population per the vendor’s memory population guide for optimal bandwidth.
- Within Samsung’s DDR5 RDIMM family, this module sits at the 16GB capacity point with a single-rank (1Rx8) layout and DDR5-5600 speed — suitable for filling channels broadly across nodes, while higher-capacity dual-rank modules are typically preferred when maximum density per channel is the priority.
- Buying tip: match the exact part number and speed grade across all modules in a single server, and confirm your CPU and motherboard officially support DDR5-5600 RDIMMs, as memory will otherwise default to a lower supported speed.
