M391A2G43BB2-CWE Samsung 1x16GB DDR4 UDIMM ECC RAM

Enterprise DDR4 ECC UDIMM Memory Expansion with the M391A2G43BB2-CWE for Reliable Server Nodes

The M391A2G43BB2-CWE is a Samsung DDR4 ECC UDIMM engineered for CPU platforms that explicitly support unbuffered ECC memory, making it a precise fit for edge servers, branch nodes, and appliance-class systems. By providing 16GB capacity at DDR4-3200, the M391A2G43BB2-CWE targets predictable latency and consistent bandwidth for general-purpose x86 workloads where data integrity must be maintained without the buffering behavior of RDIMM/LRDIMM designs.

Architecturally, the M391A2G43BB2-CWE enables scalable memory population in 288-pin DDR4 UDIMM slots while preserving ECC protection across the 72-bit data path. Dual-rank x8 organization supports balanced interleaving on compatible memory controllers, and the 1.2V operating profile aligns with modern power envelopes in dense chassis. This module integrates cleanly into systems where PCIe expansion and storage performance are already provisioned, ensuring memory is not the limiting factor for OS boot stability, virtualization overhead, or service responsiveness. Compatibility is deployment-critical: the M391A2G43BB2-CWE is intended for ECC UDIMM-capable platforms and is not interchangeable with RDIMM or LRDIMM memory architectures.

Why Choose the M391A2G43BB2-CWE?

The M391A2G43BB2-CWE delivers an enterprise-appropriate density-to-power ratio with ECC resilience in a UDIMM form factor, supporting straightforward capacity scaling for distributed infrastructure. It is well suited for standardized rollouts where deterministic behavior, low-profile mechanical fit, and repeatable qualification matter across many identical nodes.

Samsung designs server memory with a focus on signal integrity, thermal stability, and sustained reliability under continuous duty cycles, aligning with current data centre validation practices and lifecycle-managed hardware baselines.

Key Applications:

• Server boot and system memory expansion
• Edge and branch compute nodes
• Security and networking appliances
• Virtualization host RAM upgrades
