Samsung M321R6GA3PB0-CWMXJ 48G DDR5 5600 RDIMM
The Samsung M321R6GA3PB0-CWMXJ is a 48GB DDR5-5600 registered DIMM with ECC, built for enterprise servers, cloud platforms, databases, and AI computing workloads in 24/7 data center environments. It suits system integrators and data center buyers deploying DDR5-generation server platforms who need higher-density memory with registered signaling for reliability at scale. Note that final memory speed is determined by platform support and CPU memory controller capabilities, so verify compatibility with your server vendor’s QVL before ordering.

Good to know
- As a DDR5 RDIMM, this module is electrically incompatible with DDR4 and with consumer UDIMM slots — it can only be used in server/workstation platforms that explicitly support DDR5 registered memory, and DDR4 RDIMMs cannot be mixed in the same system.
- Within Samsung’s DDR5 RDIMM line, the 48GB capacity uses non-binary density (via the 3G×8 chip organization) to fill capacity gaps between 32GB and 64GB modules, letting you maximize total memory per channel on supported platforms.
- For dual-socket virtualization or database hosts, populate memory channels symmetrically per your server’s population rules; ordering modules in matched sets of identical part numbers helps ensure stable training and consistent performance across all channels.
