Samsung M321R8GA0EB0-CWM 64G DDR5 5600 RDIMM
The Samsung M321R8GA0EB0-CWM is a 64GB DDR5-5600 registered ECC DIMM aimed at procurement teams and system integrators building or expanding enterprise server and data center platforms. With its 2Rx4 dual-rank configuration and CL46 latency at 1.1V, it suits demanding workloads such as virtualization hosts, database servers, cloud instances, and AI training nodes. Note that DDR5 RDIMMs cannot be mixed with DDR4 or DDR3 modules — verify your platform supports DDR5 RDIMM before ordering.

Good to know
- RDIMMs are only compatible with server/workstation platforms that explicitly support registered DDR5 memory; they will not work in consumer desktop boards and should not be mixed with other memory generations or unbuffered module types.
- Within Samsung’s DDR5 server lineup, this 64GB dual-rank (2Rx4) module sits in the mainstream enterprise tier — dual-rank population typically improves memory bandwidth utilization per channel on virtualized and cache-tier workloads compared with single-rank modules.
- For optimal performance, populate memory channels symmetrically per your server’s population guide; if your CPU memory controller caps speeds below 5600 MT/s, the module will run at the lower supported rate.
