M391A1K43BB1-CRC Samsung 1x8GB DDR4 UDIMM ECC RAM

Enterprise DDR4 ECC UDIMM Memory Module for Entry Servers with the M391A1K43BB1-CRC

M391A1K43BB1-CRC is a Samsung DDR4 ECC UDIMM designed for CPU platforms that require unbuffered ECC memory, commonly found in entry servers and workstation-class systems where validated compatibility and predictable behavior matter more than extreme capacity per slot. The 8GB module supports 2400MT/s operation at 1.2V and integrates ECC across a 72-bit data path to help detect and correct single-bit memory errors that can destabilize services under sustained load.

In architectures where PCIe expansion and storage throughput are balanced against cost and footprint, M391A1K43BB1-CRC provides a practical building block for right-sized memory configurations without shifting to RDIMM/LRDIMM platforms. Its low-profile form factor supports dense chassis layouts and improves mechanical clearance around PCIe cards, front storage backplanes, and airflow shrouds. This makes it suitable for general-purpose compute nodes, small virtualization footprints, and edge deployments where DIMM height and serviceability are operational constraints.

Why Choose the M391A1K43BB1-CRC?

M391A1K43BB1-CRC delivers a reliable density-to-performance balance for DDR4 ECC UDIMM platforms, enabling consistent memory integrity in environments that prioritize uptime and controlled scaling. By using unbuffered ECC, it aligns with systems engineered for modest per-channel capacities while preserving enterprise-grade error protection and stable timing behavior for repeatable performance across nodes.

Samsung memory is engineered with a focus on signal integrity, manufacturing consistency, and lifecycle stability expected in modern data centre qualification processes. The module design supports long-term maintainability and predictable interoperability within standardized DDR4 server memory architectures.
