M321R6GA3PB0-CWM Samsung 1x48GB DDR5 ECC RAM

High-Density DDR5 RDIMM Server Memory Module engineered for scale-up platforms with the M321R6GA3PB0-CWM

The M321R6GA3PB0-CWM is a Samsung DDR5 RDIMM designed to expand server memory capacity while sustaining the bandwidth requirements of current Xeon and EPYC platforms. By using a 48GB registered ECC module at 5600MT/s, the M321R6GA3PB0-CWM supports high DIMM population without compromising signal integrity, enabling consistent latency behavior across multi-socket configurations.

DDR5 architectural improvements, including increased bank groups and efficient burst handling, allow the M321R6GA3PB0-CWM to feed CPU cores and attached accelerators more predictably in PCIe 5.0-class servers where I/O and storage throughput can quickly expose memory bottlenecks. As a registered DIMM, the M321R6GA3PB0-CWM is aligned with dense virtualization, database buffer growth, and analytics caching, supporting scale-up memory footprints for NVMe-centric storage tiers and mixed workload consolidation.

Why Choose the M321R6GA3PB0-CWM?

The M321R6GA3PB0-CWM provides a practical density-to-performance balance for enterprises standardizing on DDR5 RDIMM configurations, delivering ECC protection and register-based stability for large memory maps. It is well-suited for predictable scaling profiles where capacity increases must remain compatible with platform qualification requirements and ongoing fleet lifecycle management.

Samsung designs server memory with a focus on data integrity, sustained throughput, and validation against enterprise thermal and electrical envelopes. This engineering approach supports modern data centre operational standards, including high-availability maintenance practices and consistent performance across mixed server generations within approved DDR5 RDIMM platforms.
