M386A4G40DM0-CPB Samsung 1x32GB DDR4 LRDIMM ECC RAM

High-Density DDR4 LRDIMM Server Memory enabling reliable capacity scaling with the M386A4G40DM0-CPB

The M386A4G40DM0-CPB is a 32GB DDR4-2133 ECC registered LRDIMM engineered for predictable memory expansion in enterprise rack and blade servers where DIMM population strategy determines CPU utilization and VM density. By using a buffered, quad-rank x4 architecture, the M386A4G40DM0-CPB supports higher-capacity configurations with stable signaling, enabling platforms to maintain channel integrity as slots are fully populated.

In modern dual-socket server designs, memory bandwidth and latency directly influence virtualization consolidation ratios, in-memory database cache efficiency, and analytics throughput. The M386A4G40DM0-CPB provides a JEDEC-aligned, 1.2V low-profile implementation that fits constrained chassis and airflow zones while delivering ECC protection across a 72-bit data path. Although this module does not change PCIe generation or storage topology, it strengthens the system’s overall I/O efficiency by reducing paging pressure on NVMe/SAS tiers and keeping CPU cores fed with consistent working sets.

Why Choose the M386A4G40DM0-CPB?

The M386A4G40DM0-CPB is selected when architects need a capacity-optimized DIMM approach that scales reliably across large memory footprints without sacrificing serviceability. Its LRDIMM buffering improves density-to-stability characteristics for high slot counts, while ECC and registered operation support enterprise uptime expectations and standardized deployment across mixed workload clusters.

Samsung designs server memory with an emphasis on JEDEC compliance, controlled component qualification, and production consistency suited to modern data centre lifecycle management. The result is predictable interoperability with mainstream server platforms and a reliability profile aligned to continuous operation requirements.

Key Applications:

• Virtualization hosts and VDI density scaling
