M386A8K40BM1-CRC Samsung 1x64GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC LRDIMM Server Memory engineered for scale-up platforms with the M386A8K40BM1-CRC

The M386A8K40BM1-CRC is a 64GB Samsung DDR4 ECC Load-Reduced DIMM designed to extend memory capacity per channel in 2-socket and 4-socket servers without compromising signal integrity. By using LRDIMM buffering, the M386A8K40BM1-CRC supports higher populated configurations that are critical for consolidation-heavy CPU platforms where memory bandwidth and channel count must be balanced against DIMM density.

Optimised for DDR4-2400 (PC4-19200L) operation, the M386A8K40BM1-CRC aligns well with mainstream enterprise CPU generations that standardise on DDR4 and rely on predictable latency for virtualisation and data services. ECC protection with a 72-bit data path helps maintain data integrity under sustained load, while the quad-rank architecture enables larger memory footprints for in-memory caching and analytics. The low-profile 288-pin form factor improves mechanical compatibility in dense chassis layouts and high-airflow server designs.

Why Choose the M386A8K40BM1-CRC?

The M386A8K40BM1-CRC is selected when system architects need a reliable density-to-slot strategy to scale DRAM capacity while keeping socket and channel utilisation efficient. It supports standardised deployment across fleet servers, reduces the operational friction of mixed DIMM populations, and provides a stable foundation for growth in VM counts and dataset sizes within DDR4 platforms.

Samsung designs server DRAM with a focus on JEDEC compliance, consistent binning, and long-life availability to match enterprise qualification cycles. This engineering approach supports predictable interoperability, repeatable performance at 1.2V, and alignment with modern data centre serviceability and sustainability requirements.

Key Applications:

• 2-socket and 4-socket enterprise server memory expansion
• Dense virtualisation and VDI host nodes
• In-memory analytics and large dataset caching
• Database and middleware scale-up deployments
