M391A1K43DB2-CWE Samsung 1x8GB DDR4 UDIMM ECC RAM

Enterprise DDR4 ECC UDIMM Server Memory Upgrade engineered for low-profile clearance with the M391A1K43DB2-CWE

The M391A1K43DB2-CWE is a Samsung DDR4 ECC UDIMM designed for entry server and edge appliance platforms that require unbuffered DIMMs and predictable error correction behavior. In CPU platforms where the memory controller expects UDIMM topology, the M391A1K43DB2-CWE provides 8GB capacity at 3200MT/s to sustain balanced core-to-memory throughput without introducing the latency and routing considerations of registered DIMMs.

Architecturally, the M391A1K43DB2-CWE targets 1DPC configurations and mixed-population expansion scenarios where incremental capacity additions are needed while maintaining stable memory timing. Its 72-bit ECC data path supports single-bit error correction and improves resilience for virtualized services, small databases, and infrastructure roles. The low-profile 288-pin form factor of the M391A1K43DB2-CWE is optimized for constrained chassis, airflow shrouds, and dense edge systems where standard-height modules can compromise mechanical clearance and cooling.

Why Choose the M391A1K43DB2-CWE?

The M391A1K43DB2-CWE offers a pragmatic density-to-performance ratio for UDIMM-based servers, combining ECC protection with DDR4-3200 signaling to keep CPU pipelines fed under sustained load. It is well-suited for scalable rollouts where consistent module behavior, serviceability, and compatibility across similar platforms are required, enabling clean upgrade paths and controlled memory population planning.

Samsung designs server DRAM with a focus on signal integrity, long-term stability, and manufacturing consistency aligned to modern data centre qualification practices. The M391A1K43DB2-CWE reflects this engineering discipline by supporting reliable operation in 24/7 environments where memory faults directly impact uptime and recovery workflows.

Key Applications:

• Entry server memory expansion
• Edge appliances with low-profile DIMM requirements
• Virtualization hosts with ECC UDIMM platforms
• Infrastructure services and directory servers
• Web and application servers
