M391A1G43EB1-CPB Samsung 1x8GB DDR4 UDIMM ECC RAM

Enterprise DDR4 ECC UDIMM Memory Module for Stable Platform Upgrades with the M391A1G43EB1-CPB

The M391A1G43EB1-CPB is a Samsung DDR4 ECC UDIMM designed for DDR4 server and workstation platforms where predictable behavior, ECC protection, and standards-based interoperability are required. In CPU architectures that rely on the integrated memory controller, this 288-pin UDIMM supports balanced memory population for entry servers, edge nodes, and lab systems, provided the platform accepts ECC UDIMM (not RDIMM/LRDIMM).

Built to JEDEC DDR4-2133 (PC4-17000U) operation at 1.2V, the M391A1G43EB1-CPB targets stable bandwidth and latency characteristics rather than overclocking profiles, ensuring consistent performance under virtualization, directory services, and light database workloads. With a 72-bit ECC data path and dual-rank x8 organization, it helps maintain data integrity and uptime in systems where PCIe expansion and mixed storage topologies can increase operational complexity and memory error exposure.

Why Choose the M391A1G43EB1-CPB?

The M391A1G43EB1-CPB provides a practical density-to-cost step for DDR4 ECC UDIMM configurations, enabling controlled capacity expansion without altering platform validation boundaries. It is well suited for phased deployments, sparing strategies, and standardized builds that prioritize reliability and service consistency across multiple nodes.

Samsung memory engineering emphasizes process control, long-term component availability, and conformance to modern data centre qualification practices. This approach supports consistent module behavior in enterprise operating conditions, including sustained duty cycles and configuration repeatability.

Key Applications:

• Entry server memory upgrades
• ECC-enabled workstation RAM
• Edge and lab nodes requiring ECC UDIMM
