M393A8G40AB2-CVF Samsung 1x64GB DDR4 ECC RAM

High-Density DDR4 ECC Registered RDIMM engineered for scalable server memory pools with the M393A8G40AB2-CVF

The M393A8G40AB2-CVF is a 64GB DDR4 ECC Registered DIMM designed for mainstream 2-socket server platforms where memory capacity, signal integrity, and predictable latency directly impact virtualization density and database responsiveness. As a JEDEC-aligned RDIMM, the M393A8G40AB2-CVF supports stable population of large memory footprints across multi-channel CPU memory controllers typical of Intel Xeon and AMD EPYC DDR4 generations, while ECC protects workloads against soft errors in long-running enterprise environments.

With DDR4-2933 operation, the M393A8G40AB2-CVF targets balanced bandwidth per core for mixed compute, VM consolidation, and capacity-focused in-memory caching. The dual-rank x4 architecture improves reliability characteristics for server-class controllers, and the registered design reduces electrical loading to keep timing margins intact as DIMM counts increase. In PCIe-centric systems, memory reliability is the foundation that keeps accelerators and high-throughput storage fed; the M393A8G40AB2-CVF is optimized to sustain consistent memory service under high I/O and NUMA-aware workload profiles.

Why Choose the M393A8G40AB2-CVF?

The M393A8G40AB2-CVF delivers a pragmatic density-to-performance profile for enterprises expanding DRAM capacity without changing the server platform. It enables repeatable scaling across nodes, supports higher DIMM population strategies for consolidation projects, and provides ECC Registered resilience aligned with uptime-driven operations and standardized data centre build practices.

Samsung designs server memory with a validation-first engineering approach, emphasizing JEDEC compliance, controlled component quality, and long-term stability. This philosophy aligns with modern data centre requirements for predictable interoperability, lifecycle consistency, and dependable behavior under continuous duty cycles.
