M393A4K40DB3-CWE

High-Density DDR4 RDIMM Memory Module featuring ECC Registered Architecture with the M393A4K40DB3-CWE

The M393A4K40DB3-CWE is a 32GB DDR4-3200 ECC Registered DIMM designed to stabilize memory behavior in multi-socket x86 server platforms where CPU core counts and virtualization density drive sustained bandwidth demand. By using an RDIMM buffer and a 72-bit ECC data path, the M393A4K40DB3-CWE supports predictable signal integrity and error correction under continuous duty cycles, aligning with enterprise reliability requirements.

In systems built around PCIe Gen4/Gen5 expansion and NVMe-centric storage tiers, memory remains the primary determinant of consolidation efficiency. The M393A4K40DB3-CWE complements modern I/O-heavy nodes by providing a balanced 32GB capacity point per slot, enabling scalable population strategies across channels. Its dual-rank x4 organization improves access parallelism and fault tolerance characteristics compared to x8 layouts, while maintaining interoperability across mainstream server motherboards that require 288-pin DDR4 RDIMM compliance.

Why Choose the M393A4K40DB3-CWE?

The M393A4K40DB3-CWE delivers a pragmatic density-to-performance profile for growth-oriented estates, allowing architects to scale memory footprints without compromising platform stability. As an ECC RDIMM operating at 1.2V in a low-profile form factor, the M393A4K40DB3-CWE fits thermally constrained chassis designs and supports consistent uptime across clustered deployments, making it well-suited for phased rollouts and standardized spares strategies.

Samsung engineers server DRAM for long-life data center operation, emphasizing validation, component consistency, and electrical margins that align with modern server standards. With the M393A4K40DB3-CWE, Samsung targets predictable behavior across qualified CPU memory controllers and enterprise firmware baselines.
