M393A2K43EB3-CWE Samsung 1x16GB DDR4 RDIMM ECC RAM

Enterprise DDR4 ECC Registered Memory Expansion with the M393A2K43EB3-CWE RDIMM

The M393A2K43EB3-CWE is a Samsung DDR4-3200 ECC Registered DIMM (RDIMM) engineered for predictable memory scaling on Intel Xeon and AMD EPYC DDR4 server platforms. As a registered module, the M393A2K43EB3-CWE reduces electrical loading on the memory bus to support higher DIMM population per channel, helping maintain stability at scale in multi-socket configurations.

Designed around a 288-pin DDR4 interface, the M393A2K43EB3-CWE delivers 16GB capacity per DIMM at 3200 MT/s with ECC protection and a dual-rank x8 organization. This profile aligns well with virtualization and cloud hosts where balanced per-slot capacity, consistent latency behavior, and error correction are essential for 24x7 uptime. When paired with modern server expansion via PCIe and NVMe storage, the M393A2K43EB3-CWE supports memory-intensive services by keeping CPU cores fed under mixed I/O and compute contention.

Why Choose the M393A2K43EB3-CWE?

The M393A2K43EB3-CWE provides an enterprise-focused density-to-performance ratio for DDR4 fleets, enabling standardized builds across racks while preserving reliability through ECC and registered buffering. The M393A2K43EB3-CWE is suited to scalable deployments where consistent DIMM qualification, predictable behavior under heavy load, and controlled thermals in dense chassis are required.

Samsung’s server memory engineering emphasizes signal integrity, long-term validation, and tight process control to meet data centre operational requirements. With the M393A2K43EB3-CWE, this translates into dependable interoperability across qualified DDR4 platforms and sustained stability for mission-critical workloads.
