M393A4K40DB2-CVF Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC Registered RDIMM Memory Expansion with the M393A4K40DB2-CVF

The M393A4K40DB2-CVF is a 32GB DDR4 RDIMM engineered for enterprise CPU platforms that rely on registered memory to maintain signal integrity at scale. By combining ECC with a 72-bit data path, the M393A4K40DB2-CVF supports resilient operation in multi-socket servers where memory reliability and predictable latency are essential for virtualization clusters and database nodes.

Designed for DDR4-2933 JEDEC operation, the M393A4K40DB2-CVF aligns with balanced core-to-memory throughput in modern DDR4 server generations, helping reduce bottlenecks during parallel query execution and VM density growth. As a dual-rank x4 RDIMM on a 288-pin DIMM interface at 1.2V, it is optimized for capacity expansion without destabilizing memory training across large channel populations. While PCIe and storage architectures define I/O performance, the M393A4K40DB2-CVF strengthens the memory layer that feeds CPU pipelines and accelerates cache miss recovery under mixed workloads.

Why Choose the M393A4K40DB2-CVF?

The M393A4K40DB2-CVF delivers a practical density-to-performance profile for DDR4 platforms, enabling incremental scaling per node while retaining ECC Registered characteristics required for enterprise uptime. It supports consistent fleet behavior across standardized configurations, simplifying qualification, spares strategy, and controlled expansion in clustered deployments.

Samsung designs server DRAM with a focus on electrical margining, long-term availability, and strict adherence to JEDEC standards, supporting interoperability across major server boards and CPU memory controllers. This engineering discipline helps maintain stability under sustained duty cycles typical of data centre operations.
