M391A1G43EB1-CRC Samsung 1x8GB DDR4 UDIMM ECC RAM

Low-Profile ECC DDR4 UDIMM Server Memory Expansion featuring stable 2400MT/s performance with the M391A1G43EB1-CRC

The M391A1G43EB1-CRC is a Samsung server memory module designed for DDR4 UDIMM platforms that require error-correcting integrity without moving to registered DIMM architectures. As an 8GB low-profile 288-pin UDIMM, it supports capacity scaling in compact entry servers and infrastructure appliances where airflow, mechanical clearance, and serviceability are critical.

Built on DDR4-2400 (PC4-19200U) signaling at 1.2V, the M391A1G43EB1-CRC aligns well with mainstream Intel Xeon E3/E-2100/E-2200 class systems and comparable server-grade platforms that expose UDIMM slots and rely on BIOS-level ECC enablement. The 72-bit ECC data path helps protect directory, print, and light virtualization workloads from single-bit memory errors, while the dual-rank x8 organization provides balanced bank-level parallelism for predictable latency under mixed I/O and CPU scheduling. This module is a targeted memory-side optimization for systems constrained by limited channels and modest PCIe expansion, ensuring stable storage caching, control-plane services, and appliance-style deployments.

Why Choose the M391A1G43EB1-CRC?

The M391A1G43EB1-CRC delivers a practical density-to-reliability profile for IT teams standardizing on DDR4 UDIMM servers, enabling straightforward capacity upgrades with ECC protection and low-profile mechanical compatibility. It is well-suited for staged scaling, reducing risk in edge and SMB racks where predictable uptime and validated component behavior matter more than peak bandwidth.

Samsung engineers the M391A1G43EB1-CRC with a focus on signal integrity, consistent binning, and production controls aligned to enterprise lifecycle requirements. This approach supports modern data centre standards for service continuity, controlled change management, and long-term platform maintenance.
