M386A8K40BMB-CRC Samsung 1x64GB DDR4 RDIMM ECC RAM

High-Density DDR4 LRDIMM Server Memory for Scale-Up Platforms with the M386A8K40BMB-CRC

The M386A8K40BMB-CRC is a 64GB DDR4 LRDIMM engineered to expand memory capacity in x86 server platforms where CPU core counts and VM consolidation levels are constrained by available DIMM slots rather than compute. By using load-reduced buffering, the M386A8K40BMB-CRC supports higher population of memory channels at stable electrical characteristics, helping maintain predictable performance as systems scale.

Designed for DDR4-2400 JEDEC operation at 1.2V, the M386A8K40BMB-CRC integrates ECC with a 72-bit data path to improve data integrity under continuous enterprise workloads. Its quad-rank x4 architecture is aligned to balanced bandwidth delivery across populated channels, while the low-profile form factor supports dense 1U/2U server layouts with constrained airflow paths. As a memory building block, the M386A8K40BMB-CRC complements PCIe expansion and storage scaling by removing memory pressure that can otherwise limit in-memory caching, database buffer pools, and virtualised host headroom.

Why Choose the M386A8K40BMB-CRC?

The M386A8K40BMB-CRC is selected when capacity-per-slot and enterprise reliability are primary design targets, enabling higher DIMM density without sacrificing operational stability. For IT teams standardising configurations, the M386A8K40BMB-CRC supports repeatable scaling profiles across clusters, reducing qualification effort and simplifying maintenance cycles in production environments.

Samsung designs server memory with a focus on signal integrity, consistency across thermal envelopes, and long-life availability practices expected in modern data centres. This approach aligns with validated platform requirements for uptime-centric infrastructure and controlled change management.
