M321R4GA3PB0-CWM

High-Performance DDR5 RDIMM Server Memory Expansion featuring ECC Registered Architecture with the M321R4GA3PB0-CWM

M321R4GA3PB0-CWM is a Samsung DDR5 RDIMM engineered for DDR5-capable Xeon Scalable and EPYC-class platforms where registered, ECC-protected memory is mandatory for predictable uptime. This 32GB module targets balanced capacity scaling in 1U/2U rack servers, delivering a stable memory foundation for virtualisation hosts and general enterprise compute nodes.

Designed around JEDEC PC5-44800R at 5600MT/s, M321R4GA3PB0-CWM supports modern CPU memory controllers that benefit from higher bandwidth per channel and improved signalling integrity through the registered DIMM architecture. Its dual-rank x8 organisation helps maintain efficient interleaving and bank-level parallelism under mixed read/write pressure, while ECC and on-die error correction strengthen data integrity for long-running workloads. In PCIe Gen5 dense platforms, M321R4GA3PB0-CWM complements high I/O expansion by keeping memory throughput aligned with NVMe storage tiers and accelerator-fed pipelines, reducing stalls in data-intensive services.

Why Choose the M321R4GA3PB0-CWM?

M321R4GA3PB0-CWM provides an enterprise-appropriate density-to-performance profile for scaling per-socket memory without compromising reliability requirements. It enables consistent fleet configuration across nodes, supports predictable performance under consolidation, and simplifies capacity planning for growth-driven deployments where RDIMM ECC is a platform prerequisite.

Samsung applies disciplined DRAM process control and validation to ensure interoperability and sustained operation in modern data centre thermal envelopes. M321R4GA3PB0-CWM is built to align with server lifecycle expectations, supporting standardised qualification workflows and stable operation across diverse OEM BIOS and memory training implementations.

Key Applications:

Server virtualisation and consolidation
Database and in-memory caching tiers
Enterprise application hosting
VDI and session-based compute
Infrastructure monitoring and logging
