M393A2K40DB2-CVF Samsung 1x16GB DDR4 ECC RAM

Enterprise DDR4 RDIMM Memory Expansion for Stable Compute Nodes with the M393A2K40DB2-CVF

The M393A2K40DB2-CVF is a Samsung 16GB DDR4-2933 ECC Registered DIMM engineered to strengthen memory capacity and integrity in modern x86 server platforms, including current Intel Xeon and AMD EPYC generations that rely on RDIMM signaling for scalable channel loading. In virtualisation clusters and database hosts, the M393A2K40DB2-CVF supports predictable latency behavior and error containment under sustained, multi-tenant pressure.

Designed around JEDEC-compliant DDR4-2933 (PC4-23466R), the M393A2K40DB2-CVF integrates registered buffering and ECC across a 72-bit data path to maintain stability as memory populations grow. Its single-rank x4 organization aligns with enterprise RAS objectives and helps optimize reliability characteristics in high-density DIMM configurations. While PCIe generation, GPU attach, and storage tiers define I/O throughput, the M393A2K40DB2-CVF addresses the foundational constraint of memory headroom that impacts VM consolidation ratios, in-memory caching, and transactional concurrency.

Why Choose the M393A2K40DB2-CVF?

By deploying the M393A2K40DB2-CVF, architects gain a balanced density-to-performance step that preserves platform compatibility and operational confidence, particularly when scaling nodes consistently across racks. The M393A2K40DB2-CVF is suited to standardized build sheets where ECC RDIMM reliability and controlled thermals are required for repeatable rollouts and lifecycle-managed expansions.

Samsung designs server DRAM with process control and validation aligned to data centre duty cycles, emphasizing signal integrity, long-term availability, and compliance with mainstream server memory qualification practices. The M393A2K40DB2-CVF reflects this engineering approach by targeting stable, interoperable deployments across validated motherboard and BIOS memory QVL ecosystems.
