M393A2K40CB2-CVF Samsung 1x16GB DDR4 RDIMM ECC RAM

High-Performance DDR4 RDIMM Server Memory Module for reliable scale-out capacity with the M393A2K40CB2-CVF

The M393A2K40CB2-CVF is a Samsung 16GB DDR4-2933 ECC Registered RDIMM designed for predictable memory behaviour in 2-socket server platforms running virtualisation, general compute, and managed enterprise applications. As a JEDEC-compliant RDIMM, it targets stability over tuning features, ensuring consistent operation across mixed fleet deployments and standard BIOS configurations.

By using a registered buffer and ECC data path, the M393A2K40CB2-CVF supports higher DIMM population and sustained uptime under multi-VM consolidation and memory-intensive services. In CPU platforms that expose multi-channel DDR4 controllers, balanced DIMM placement with this module improves channel utilisation and reduces performance variability caused by uneven capacity per channel. While PCIe and storage architectures remain platform-dependent, DRAM latency and bandwidth directly influence I/O-heavy workloads through caching, buffering, and queue depth efficiency, making the M393A2K40CB2-CVF a practical upgrade for nodes constrained by memory pressure.

Why Choose the M393A2K40CB2-CVF?

The M393A2K40CB2-CVF provides a disciplined capacity step that aligns with enterprise reliability requirements, enabling controlled scaling of host memory without introducing non-standard profiles. Its ECC Registered design supports dense configurations in rack servers, helping operations teams standardise DIMM inventories, keep service windows short, and maintain consistent performance across clusters.

Samsung engineers the M393A2K40CB2-CVF to meet stringent server qualification expectations, focusing on signal integrity, thermal stability at 1.2V, and long-life component consistency. This approach supports modern data centre operational models where repeatability, interoperability, and lifecycle continuity matter as much as raw throughput.
