Samsung M321R2GA3PB0-CWM 16G DDR5 5600 RDIMM
The Samsung M321R2GA3PB0-CWM is a 16GB DDR5 ECC registered DIMM (RDIMM) rated at DDR5-5600, aimed at enterprise server buyers, system integrators, and data center operators provisioning memory for cloud computing, virtualization, and general-purpose server workloads. As a registered ECC module, it targets platforms specifically designed for RDIMMs rather than desktop UDIMM sockets. Note that actual speed may depend on platform support and CPU memory controller capabilities.

Good to know
- Compatibility: DDR5 RDIMMs cannot be mixed with DDR4 modules, and RDIMMs require server/workstation platforms with registered-DIMM support — they will not fit or operate in standard desktop DDR5 UDIMM slots.
- Within the DDR5 RDIMM family, this 16GB 1Rx8 module at DDR5-5600 sits in the mainstream density tier, well suited as a high-speed base module or as matched sticks for channel population in virtualization hosts and cache-tier deployments.
- Buying tip: for multi-channel server builds, order modules of identical part number, capacity, and rank configuration (1Rx8) to ensure balanced channel population and consistent JEDEC timing behavior; verify your platform’s officially supported memory speed list before ordering.
