M393A8G40BB4-CWE Samsung 1x64GB DDR4 ECC RAM

High-Density DDR4 RDIMM Server Memory enabling scalable capacity with the M393A8G40BB4-CWE

The M393A8G40BB4-CWE is a 64GB DDR4-3200 ECC Registered DIMM designed to expand memory capacity in enterprise CPU platforms where predictable latency, signal integrity, and sustained uptime are mandatory. As an RDIMM, it supports registered buffering to stabilize the memory channel under higher DIMM population, helping modern dual-socket servers maintain bandwidth and reliability for consolidation-heavy virtualization and private cloud nodes.

Architected for JEDEC DDR4-3200 operation, the M393A8G40BB4-CWE aligns with mainstream server generations that balance core density with memory throughput across PCIe expansion fabrics and mixed storage tiers. By enabling larger memory footprints per host, it reduces paging pressure on NVMe/SAS storage and supports higher VM density, database buffer pools, and in-memory caching layers. The dual-rank x4 organization and 72-bit ECC data path are tuned for enterprise error detection and correction, while the low-profile 288-pin form factor supports tight airflow and serviceability constraints in dense rack deployments.

Why Choose the M393A8G40BB4-CWE?

The M393A8G40BB4-CWE provides an efficient density-to-slot profile for scaling capacity without redesigning the server bill of materials, enabling consistent performance across nodes as memory population increases. It is engineered for stable operation in 24/7 environments, supporting predictable platform scaling strategies for clusters, virtualization farms, and capacity-focused database hosts.

Samsung server DRAM follows a validation philosophy centered on standards compliance, stringent qualification, and lifecycle consistency to meet modern data centre requirements. This approach supports reliable fleet operations, controlled change management, and sustained interoperability across enterprise server platforms.
