Samsung M321R4GA3PB0-CWM 32G DDR5 5600 RDIMM
The Samsung M321R4GA3PB0-CWM is a 32GB DDR5-5600 ECC registered DIMM (RDIMM) built for enterprise servers, cloud platforms, and data center environments running 24/7. It suits buyers provisioning virtualization hosts, database or cache tiers, and high-density compute nodes where registered DDR5 with error correction is required. Note that DDR5 RDIMMs cannot be mixed with DDR4 or non-registered modules on the same platform — verify your server’s chipset and BIOS support before ordering.

Good to know
- Compatibility: DDR5 RDIMMs are not backward or forward compatible — they will not work in DDR4 slots and do not mix with DDR5 UDIMM/SODIMM modules; always confirm your platform supports registered DDR5 at this capacity and rank configuration.
- Within Samsung’s DDR5 RDIMM family, this dual-rank 2Rx8 32GB module sits in the mainstream server capacity tier, commonly used in balanced channel population across multi-DIMM-per-channel server boards.
- Buying tip: when populating all memory channels for virtualization or cache-tier workloads, keep capacity, rank, and part number uniform across modules to avoid training and downclocking issues.
