M393A4G43BB4-CWE Samsung 1x32GB DDR4 ECC RAM

High-Density DDR4 RDIMM Server Memory for Scalable Compute and Virtualization with the M393A4G43BB4-CWE

The M393A4G43BB4-CWE is a Samsung 32GB DDR4 RDIMM engineered for enterprise server platforms where predictable latency, ECC integrity, and capacity scaling are critical. Deployed in modern Intel Xeon and AMD EPYC generations that expose multi-channel DDR4 controllers, this registered DIMM supports stable operation under sustained memory bandwidth demand typical of consolidation and mixed I/O workloads.

As a DDR4-3200 module, the M393A4G43BB4-CWE aligns with platforms designed around high-throughput PCIe expansion, ensuring that accelerators, NICs, and NVMe storage are not bottlenecked by undersupplied memory bandwidth. The registered architecture improves signal integrity at higher DIMM populations per channel, while ECC safeguards 72-bit data paths for long-running VMs, databases, and caching tiers. In balanced server designs, the M393A4G43BB4-CWE enables capacity growth without compromising stability, supporting consistent performance across NUMA domains and dense rack deployments.

Why Choose the M393A4G43BB4-CWE?

The M393A4G43BB4-CWE delivers an efficient density-to-performance profile for standard 288-pin RDIMM slots, making it well-suited for scaling memory footprints in virtualization clusters and private cloud nodes. Its registered ECC design strengthens reliability at scale, supports higher channel loading, and helps maintain deterministic behavior during peak utilization, simplifying rollout across homogeneous server fleets and lifecycle upgrades.

Samsung memory is built around disciplined qualification, process control, and compatibility focus for data centre standards. The engineering approach emphasizes consistent electrical characteristics, long-term availability, and server-centric validation to support uptime targets and controlled change management in enterprise environments.

Key Applications:

• Virtualization hosts and VM consolidation
• General-purpose rack server memory expansion
• Database services and in-memory caching
• Private cloud compute nodes
