M386A8K40BM2-CTD Samsung 1x64GB DDR4 LRDIMM ECC RAM

High-Density DDR4 LRDIMM Server Memory for Scale-Up Platforms with the M386A8K40BM2-CTD

The M386A8K40BM2-CTD is a 64GB DDR4 LRDIMM engineered for enterprise CPU platforms that depend on stable, standards-based memory behavior across multi-socket servers. In virtualization hosts and database nodes, the M386A8K40BM2-CTD supports predictable performance by operating at JEDEC DDR4-2666 timing, avoiding non-standard profiles and keeping memory training consistent during fleet-wide rollouts.

As a quad-rank x4 72-bit (ECC) registered module, M386A8K40BM2-CTD is designed to improve capacity density per memory channel, enabling higher VM consolidation ratios and larger in-memory working sets. Its low-profile 288-pin DIMM format fits dense 1U/2U chassis with constrained airflow, while the 1.2V DDR4 electrical design helps control power and thermals in heavily populated memory configurations. By increasing per-socket memory headroom, M386A8K40BM2-CTD reduces pressure on storage tiers and PCIe-attached expansion by keeping more data close to the CPU for latency-sensitive services.

Why Choose the M386A8K40BM2-CTD?

The M386A8K40BM2-CTD delivers a practical density-to-reliability balance for enterprise environments where uptime and uniformity matter more than peak benchmark tuning. It enables scalable memory population plans, supports consistent behavior across identical server builds, and aligns well with capacity-led upgrades that extend the useful life of compute nodes without disruptive platform changes.

Samsung focuses on high-volume, tightly controlled DRAM manufacturing with validation oriented to modern data centre standards. This approach emphasizes signal integrity, long-term stability under continuous load, and predictable interoperability in registered ECC server memory deployments.
