M378A2K43EB1-CWE Samsung 1x16GB DDR4 UDIMM ECC RAM

High-Density DDR4 ECC UDIMM Memory Expansion with the M378A2K43EB1-CWE for Entry Servers and Workstations

The M378A2K43EB1-CWE is a 16GB DDR4-3200 ECC UDIMM designed for CPU platforms that require unbuffered ECC memory, common in entry servers and professional workstations where RDIMM/LRDIMM support is not available. By delivering 3200 MT/s at 1.2V, the M378A2K43EB1-CWE helps increase memory bandwidth per channel while maintaining ECC protection for improved data integrity under sustained CPU-bound workloads.

Architecturally, the M378A2K43EB1-CWE targets DDR4-generation memory controllers across mainstream server/workstation CPU families, enabling practical capacity scaling without changing the platform. Its 72-bit data path provides single-bit error correction and detection, supporting operational stability for virtualization hosts, storage services, and engineering applications. The dual-rank x8 organization improves rank-level parallelism and can enhance real-world throughput when channels are populated correctly. As a low-profile 288-pin DIMM (31.25 mm), the M378A2K43EB1-CWE fits dense chassis and constrained clearance systems, helping preserve airflow and serviceability around PCIe expansion and storage backplanes.

Why Choose the M378A2K43EB1-CWE?

The M378A2K43EB1-CWE provides a balanced density-to-performance profile for ECC UDIMM-only platforms, enabling predictable scaling in mixed fleet deployments. It supports reliable population planning for dual-channel and multi-channel memory architectures, keeping capacity upgrades aligned with controller limits while maintaining enterprise-grade stability for always-on operations.

Samsung engineers this module with a focus on signal integrity, consistent timing behavior, and qualification practices aligned with modern data centre standards, supporting repeatable deployment outcomes across validated server and workstation configurations.
