M386A8K40DM2-CWE Samsung 1x64GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC LRDIMM Server Memory Expansion with the M386A8K40DM2-CWE

The M386A8K40DM2-CWE is a 64GB DDR4-3200 ECC LRDIMM designed for enterprise servers that require higher per-socket memory capacity without sacrificing signal integrity at scale. By using a load-reduced architecture, the M386A8K40DM2-CWE supports larger memory populations on compatible CPU platforms while maintaining stable operation under continuous, multi-tenant workloads.

Deployed in modern x86 server generations that support RDIMM/LRDIMM channels, the M386A8K40DM2-CWE enables denser virtualization and in-memory datasets by reducing electrical loading compared with standard RDIMMs. This aligns with architectures that prioritize PCIe expansion for accelerators and high-speed NICs while keeping memory bandwidth and capacity balanced for database, analytics, and software-defined storage nodes. With DDR4-3200 performance and ECC protection, the M386A8K40DM2-CWE helps sustain predictable latency behavior for transaction-heavy applications and consolidation-focused clusters.

Why Choose the M386A8K40DM2-CWE?

The M386A8K40DM2-CWE is selected when platform scalability and capacity-per-slot are decisive, particularly in LRDIMM-qualified systems where quad-rank density is necessary. It provides a practical density-to-performance profile for expanding hosts without redesigning storage or PCIe layouts, while ECC and server-grade validation support operational continuity in enterprise change windows.

Samsung engineers server DRAM with a focus on consistent manufacturing control, qualification discipline, and long-life availability aligned to data centre standards. The M386A8K40DM2-CWE follows this approach with low-profile mechanical compatibility and parameters tailored for predictable deployment in high-density racks.

Key Applications:

• Enterprise server memory upgrades for DDR4 LRDIMM platforms
• Virtualization and private cloud hosts
• In-memory databases and caching tiers
• Analytics and reporting nodes
• Scale-up application servers
