M392A4K40BM0-CRC Samsung 1x32GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Server Memory Expansion for Reliable Capacity Scaling with the M392A4K40BM0-CRC

The M392A4K40BM0-CRC is a 32GB DDR4 ECC Registered DIMM engineered to expand memory headroom in DDR4-era Intel Xeon and AMD EPYC platforms where stability and predictable latency matter. By using RDIMM buffering and a 72-bit ECC data path, the M392A4K40BM0-CRC supports higher memory population levels and reduces signal-loading constraints that can limit large DIMM configurations in multi-socket servers.

Designed around JEDEC-compliant DDR4-2400 operation at 1.2V, the M392A4K40BM0-CRC aligns with common platform memory controllers and BIOS qualification policies, helping preserve system interoperability during maintenance windows and rolling upgrades. Its dual-rank x4 organization improves fault-tolerance characteristics compared to x8 devices, while the low-profile 288-pin form factor ensures mechanical fit in dense 1U/2U chassis, adjacent PCIe risers, and airflow-optimized memory banks. The result is a practical capacity upgrade path for virtualization clusters, database nodes, and memory-constrained enterprise applications without changing CPU, PCIe topology, or storage architecture.

Why Choose the M392A4K40BM0-CRC?

The M392A4K40BM0-CRC delivers a balanced density-to-compatibility profile for servers that must scale memory while maintaining ECC RDIMM reliability, consistent boot behavior, and service-friendly expansion planning. It is well suited for standardized fleet deployments where predictable DIMM characteristics simplify qualification, spares management, and node-to-node configuration consistency.

Samsung server memory is built with a focus on long-term platform stability, controlled component selection, and disciplined manufacturing that supports enterprise lifecycle requirements. This approach aligns with modern data center expectations for repeatable performance, validated interoperability, and dependable operation under sustained workloads.
