M386AAG40DM3-CWE Samsung 1x128GB DDR4 LRDIMM RAM

High-Density DDR4 LRDIMM Server Memory featuring quad-rank scalability with the M386AAG40DM3-CWE

The M386AAG40DM3-CWE is a Samsung 128GB DDR4-3200 LRDIMM engineered to maximize memory capacity per socket in enterprise CPU platforms where core counts and VM density drive architectural decisions. In modern virtualization and in-memory database nodes, the M386AAG40DM3-CWE enables large, stable memory footprints while maintaining predictable latency characteristics under sustained multi-tenant load.

Designed for DDR4 server generations, the M386AAG40DM3-CWE integrates ECC and registered/load-reduced signaling to support higher DIMM populations without compromising signal integrity. This directly benefits PCIe-attached I/O and NVMe storage architectures by reducing memory pressure on caching, indexing, and buffer pools, helping CPU resources stay aligned with throughput targets. For scale-up consolidation, the M386AAG40DM3-CWE supports a configuration approach focused on fewer, larger modules to simplify population rules and improve serviceability in dense rack deployments.

Why Choose the M386AAG40DM3-CWE?

The M386AAG40DM3-CWE delivers a pragmatic density-to-performance ratio for DDR4 environments that need 128GB-class modules with enterprise RAS behavior. By using a load-reduced, quad-rank design, the M386AAG40DM3-CWE is well suited to scalable memory topologies that prioritize capacity, consistent uptime, and straightforward expansion planning across multi-socket servers.

Samsung applies a reliability-first engineering philosophy across its server DRAM portfolio, emphasizing tight component validation, controlled manufacturing, and compatibility alignment with mainstream data center platforms. The M386AAG40DM3-CWE supports stable operation at 1.2V and is built to integrate cleanly into standardized enterprise maintenance and qualification processes.

Key Applications:

• Virtualization hosts and VDI density
• In-memory databases and caching tiers
• Scale-up server consolidation
• Memory-intensive analytics
