Samsung M321R4GA3EB0-CWM 32G DDR5 5600 RDIMM
The Samsung M321R4GA3EB0-CWM is a 32GB DDR5 ECC Registered DIMM (RDIMM) running at 5600 MT/s, aimed at integrators and data center buyers populating enterprise servers, cloud platforms, and workstations. Its 2Rx8 dual-rank configuration supports higher channel density on DDR5 server platforms, and the low 1.1V operating voltage helps manage thermal load in dense chassis. Note that DDR5 RDIMMs are not backward compatible with DDR4 platforms—verify your board’s memory generation and QVL before ordering.

Good to know
- As an RDIMM with ECC, this module fits registered server channels only; it will not run in unbuffered desktop slots and cannot be mixed with DDR4 or non-registered DDR5 modules in the same channel.
- At 5600 MT/s with CL46 and a 2Rx8 layout, it sits at the high end of the DDR5 RDIMM speed range, suited to virtualization hosts and cache-tier workloads; actual bus speed may downclock if the platform memory controller supports a lower rate.
- Buying tip: populate modules in matched sets (same capacity, rank, and speed) per your server vendor’s channel population guide to enable multi-channel bandwidth and stable training at 5600 MT/s.
