M393A8G40MB2-CVF Samsung 1x64GB DDR4 RDIMM ECC RAM

High-Density DDR4 RDIMM Server Memory enabling scalable capacity expansion with the M393A8G40MB2-CVF

The M393A8G40MB2-CVF is a 64GB DDR4 RDIMM engineered for enterprise CPU platforms that depend on registered memory to sustain high DIMM population and predictable signaling at scale. As data centres standardise on DDR4 server generations, the M393A8G40MB2-CVF supports consistent memory throughput for virtualization clusters and database hosts where capacity per socket is often the primary constraint.

Built as a 288-pin, dual-rank, ECC registered DIMM, the M393A8G40MB2-CVF provides a stable 72-bit data path and JEDEC-compliant operation at DDR4-2933 (PC4-23466R) with 1.2V efficiency. For system architects, this translates into cleaner expansion planning across multi-channel memory topologies while preserving PCIe lanes for accelerators and high-speed I/O. By increasing per-DIMM density, the M393A8G40MB2-CVF helps defer node count growth, keeping storage and network fabrics simpler while enabling larger in-memory working sets.

Why Choose the M393A8G40MB2-CVF?

The M393A8G40MB2-CVF is selected when reliability, capacity scaling, and operational consistency matter more than transient peak benchmarks. It enables a strong density-to-performance profile for DDR4 RDIMM servers, supports predictable fleet qualification through JEDEC alignment, and reduces maintenance risk through ECC protection and registered buffering that stabilizes large-memory configurations.

Samsung designs enterprise memory with process control and validation focused on long duty cycles, thermal tolerance, and platform interoperability. The result is a module class aligned with modern data centre standards for uptime-driven operations and repeatable deployment across approved server bill-of-materials.
