M393A2K40DB3-CWE Samsung 1x16GB DDR4 ECC RAM

Enterprise DDR4 RDIMM Memory Expansion for 2-Socket Platforms with the M393A2K40DB3-CWE

The M393A2K40DB3-CWE is a Samsung 16GB DDR4 RDIMM designed for enterprise servers that require ECC protection and registered buffering to maintain signal integrity at scale. Deployed across modern 2-socket CPU platforms, the module supports stable memory channel loading and predictable latency behavior for mixed virtualization and general-purpose compute nodes.

With JEDEC-aligned 3200 MT/s operation (PC4-25600R) at 1.2V, the M393A2K40DB3-CWE enables balanced bandwidth per channel without relying on vendor-specific overclocking profiles. Its 288-pin low-profile form factor suits dense rack configurations, while the 72-bit data path delivers ECC correction to reduce soft-error impact under sustained workloads. Single-rank x4 organization supports compatible memory population rules in mainstream server boards, helping architects scale capacity in a controlled, validated manner when standardizing on 16GB DIMMs.

Why Choose the M393A2K40DB3-CWE?

The M393A2K40DB3-CWE provides an efficient density-to-performance ratio for incremental upgrades, enabling consistent fleet configurations while preserving platform reliability. For IT teams expanding memory footprints across clustered hosts, the M393A2K40DB3-CWE supports repeatable deployments, predictable interoperability with RDIMM-capable controllers, and scalability through structured channel population.

Samsung engineers its server DRAM for long lifecycle availability, stringent validation, and alignment with data center operational standards. The M393A2K40DB3-CWE reflects a focus on signal margin, ECC reliability, and JEDEC compliance to support enterprise qualification processes and change-controlled infrastructure updates.
