M321R2GA3EB0-CWM Samsung 1x16GB DDR5 RDIMM ECC RAM

High-Performance DDR5 RDIMM Server Memory Module for scalable compute featuring ECC reliability with the M321R2GA3EB0-CWM

The M321R2GA3EB0-CWM is a 16GB DDR5 RDIMM engineered for modern server CPU platforms that leverage higher memory channel bandwidth to improve consolidation efficiency in virtualization hosts and general-purpose compute nodes. With ECC and registered signaling, the M321R2GA3EB0-CWM supports electrically stable operation across densely populated DIMM configurations, helping maintain predictable performance under mixed tenant workloads.

Built around DDR5 at 5600MT/s, the M321R2GA3EB0-CWM aligns with current-generation PCIe 5.0 server designs by reducing memory-side contention that can otherwise bottleneck high-throughput I/O, NVMe storage, and accelerator-attached pipelines. The single-rank x8 organization and 72-bit data path provide a balanced capacity-per-slot profile for scale-out clusters, while the 288-pin RDIMM form factor and 1.1V operating envelope support efficient thermal and power planning in high-density chassis.

Why Choose the M321R2GA3EB0-CWM?

The M321R2GA3EB0-CWM delivers a pragmatic density-to-performance ratio for DDR5-capable servers where reliability, serviceability, and consistent latency are mandatory. As an ECC Registered module, the M321R2GA3EB0-CWM is well suited for expanding memory footprints without compromising signal integrity, enabling straightforward scaling across multi-socket nodes and repeatable deployment across standardized racks.

Samsung designs server memory with a focus on qualification discipline, long lifecycle consistency, and compatibility with enterprise platform validation. This approach supports operational stability in data centre environments that require controlled change management and adherence to modern power and thermal standards.

Key Applications:

• Virtualization and VM consolidation
• General-purpose compute nodes
• Memory expansion for DDR5 server platforms
• Scale-out infrastructure standardization
