Samsung M321RYGA0PB2-CCP 96G DDR5 6400 RDIMM
The Samsung M321RYGA0PB2-CCP is a 96GB DDR5 registered ECC memory module rated at 6400 MT/s, aimed at system integrators and data center buyers provisioning enterprise servers, virtualization hosts, and AI or HPC compute nodes. Its 2Rx4 dual-rank layout on x4 DRAM provides ECC-protected capacity suited to memory-hungry workloads such as large VM consolidation and cache tiers. Note that as a DDR5 RDIMM it can only be used in DDR5-capable platforms and cannot be mixed with DDR4 modules.

Good to know
- Compatibility: DDR5 RDIMMs are keyed and electrically different from DDR4 — they will not fit or operate in DDR4 slots, and mixing generations on the same board is not possible. Verify your server platform supports 96GB modules and 6400 MT/s operation; on some CPUs the effective data rate may be limited by the memory controller, so confirm with the platform QVL.
- Family positioning: Within Samsung’s DDR5 RDIMM lineup, this part targets the high-capacity/high-bandwidth tier — the dual-rank 2Rx4 configuration balances density with signal integrity, making it a common choice for two-socket virtualization hosts and memory-bandwidth-sensitive workloads where populating all channels evenly yields the best aggregate throughput.
- Buying tip: Since the module is in mass production, plan channel population (e.g., matched modules per memory channel) to hit rated bandwidth, and confirm quantity availability and lead time with our export desk before placing bulk orders for multi-node deployments.
