M392A4K40BM0-CPB Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC RDIMM Memory for Enterprise Servers with the M392A4K40BM0-CPB

The M392A4K40BM0-CPB is a Samsung 32GB DDR4 ECC Registered RDIMM engineered for predictable latency, memory integrity, and stable scaling in mainstream x86 server platforms. As a dual-rank 288-pin VLP module, it supports high DIMM population strategies while maintaining mechanical clearance in dense 1U/2U chassis, making it suitable for virtualization hosts and consolidation nodes where capacity per socket directly impacts VM density.

Operating at DDR4-2133 (PC4-17000R) with JEDEC CL15 timings and 1.2V, the M392A4K40BM0-CPB aligns with balanced CPU memory-controller profiles commonly deployed with PCIe-based expansion and mixed I/O. ECC with registered buffering improves signal integrity across populated channels, reducing error exposure under sustained load. This supports storage and database stacks where PCIe-attached NICs, HBAs, and NVMe tiers increase concurrency and demand consistent memory behavior for caching, indexing, and transactional processing.

Why Choose the M392A4K40BM0-CPB?

The M392A4K40BM0-CPB delivers an efficient density-to-reliability profile for enterprise fleets that must scale capacity without compromising uptime. Its registered ECC architecture is designed for multi-DIMM per channel configurations, enabling repeatable performance during node expansion, refresh cycles, and standardized spares management. The VLP form factor also supports deployment in airflow-sensitive racks and high-port-count systems.

Samsung designs server memory with a focus on qualification discipline, component consistency, and long-term platform compatibility. The result is a module engineered to meet data centre operational standards, including RoHS compliance and predictable behavior across validated server BIOS and firmware baselines.

Key Applications:

• Server virtualization and consolidation
• Database and transactional systems
• Enterprise application servers
• In-memory caching and middleware
