M386A8K40DM2-CVF Samsung 1x64GB DDR4 LRDIMM ECC RAM

High-Density DDR4 LRDIMM Server Memory for Controller-Efficient Scaling with the M386A8K40DM2-CVF

The M386A8K40DM2-CVF is a Samsung enterprise DDR4 LRDIMM designed for capacity-driven server builds on DDR4 Xeon and EPYC platforms where memory-controller loading is the primary scaling constraint. By using load-reduced buffering, the M386A8K40DM2-CVF supports higher DIMM populations per socket compared with standard RDIMM approaches, enabling predictable performance at large memory footprints while maintaining ECC data protection.

Aligned with PCIe-based I/O expansion and NVMe-heavy storage tiers typical of modern 1U and 2U rack servers, the M386A8K40DM2-CVF helps keep the CPU’s memory channels efficiently utilized under consolidation pressure. Its 64GB quad-rank organization and DDR4-2933 operating point are engineered for stable bandwidth delivery in multi-socket configurations, supporting virtualization density, analytics staging, and in-memory dataset growth without introducing unnecessary platform changes.

Why Choose the M386A8K40DM2-CVF?

The M386A8K40DM2-CVF is selected when architectural priority is maximizing GB per node while controlling electrical load on the integrated memory controller. This improves density-to-performance behavior in heavily populated memory banks, supports scalable node standardization, and reduces operational risk for enterprise deployments that require consistent DIMM behavior across large fleets.

Samsung designs the M386A8K40DM2-CVF with a reliability-first engineering philosophy, focusing on signal integrity, qualification discipline, and compatibility with mainstream server validation matrices. This results in memory modules aligned to data centre expectations for uptime, serviceability, and predictable lifecycle planning.

Key Applications:

• DDR4 Xeon and EPYC memory expansion using LRDIMM
• Virtualization and VDI host consolidation
• In-memory databases
• Analytics and caching tiers
• High-density multi-tenant compute nodes
