M386A4K40BB0-CRC Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 LRDIMM Server Memory engineered for ECC reliability with the M386A4K40BB0-CRC

The M386A4K40BB0-CRC is a Samsung 32GB DDR4 LRDIMM designed for server-class memory subsystems where capacity per slot and signal integrity are critical to platform stability. As a load-reduced DIMM, it lowers the electrical load on the memory channel compared to traditional RDIMMs, enabling higher population of DIMM slots in 2-socket and 4-socket CPU platforms without compromising enterprise uptime expectations.

Built on DDR4-2400 (PC4-19200L) JEDEC timings at 1.2V, the M386A4K40BB0-CRC integrates 72-bit ECC with a dual-rank x4 organization to improve fault isolation characteristics that matter in virtualisation hosts and database tiers. In modern PCIe-based server designs, memory bandwidth and latency directly affect GPU feeding, storage caching, and network I/O concurrency; deploying the M386A4K40BB0-CRC supports balanced compute-to-memory ratios for private cloud nodes, general-purpose compute pools, and ERP scaling where predictable behaviour is preferred over overclocking features.

Why Choose the M386A4K40BB0-CRC?

The M386A4K40BB0-CRC provides a pragmatic density-to-performance profile for DDR4 platforms that must scale memory footprints while maintaining stability under sustained utilisation. Its LRDIMM architecture is suited to expanding capacity across many populated slots, supporting controlled growth in VM density and in-memory data structures with enterprise-grade ECC assurance and consistent JEDEC operation.

Samsung engineers server memory with a validation-first philosophy focused on signal integrity, controller interoperability, and long-term operating margins. The module aligns with data centre standards for 288-pin DDR4 LRDIMM deployments, ensuring predictable behaviour across qualified server boards and firmware configurations.

Key Applications:

• Virtualisation hosts
• Database and ERP memory expansion
• Private cloud compute nodes
• General-purpose server consolidation
