M386AAG40AM3-CWE Samsung 1x128GB DDR4 LRDIMM ECC RAM

High-Capacity DDR4 LRDIMM Server Memory Module for Scale-Up Platforms with the M386AAG40AM3-CWE

The M386AAG40AM3-CWE is a 128GB DDR4-3200 LRDIMM engineered to expand memory footprints on modern multi-socket CPU platforms where capacity, signal integrity, and predictable latency are critical. By combining load-reduced buffering with ECC Registered operation, the M386AAG40AM3-CWE supports higher DIMM population strategies while maintaining stable timing behavior across dense memory channels.

Designed for DDR4 server architectures, the M386AAG40AM3-CWE aligns with systems that must sustain high VM consolidation ratios, large in-memory working sets, and steady bandwidth under parallel workloads. Its 288-pin low-profile DIMM form factor supports front-to-back airflow constraints in rack servers, while the quad-rank, 72-bit data path delivers the capacity scaling required for memory-bound analytics and scale-up database nodes. In platforms where PCIe expansion and storage tiers are already optimized, the M386AAG40AM3-CWE addresses the primary limiter: DRAM capacity per socket without compromising enterprise-grade reliability.

Why Choose the M386AAG40AM3-CWE?

The M386AAG40AM3-CWE provides a practical density-to-performance profile for data centers standardizing on DDR4, enabling higher total RAM per host with fewer slots consumed. This supports cleaner upgrade paths, reduces reconfiguration risk during capacity expansions, and helps maintain consistent fleet behavior across clustered deployments where memory sizing directly impacts service-level stability.

Samsung designs server memory with a focus on validation discipline, component quality, and long-term platform compatibility. The result is an enterprise DIMM built to meet data center expectations for uptime, traceability, and repeatable operation in continuously loaded environments.

Key Applications:

• Server virtualisation and private cloud expansion
• In-memory databases
• Analytics and caching tiers
• Scale-up CPU platforms with high DIMM density
