About the Samsung 128GB DDR4 LRDIMM M386AAG40EM3-CWE
Samsung DDR4-3200 128GB LRDIMM — high-capacity, load-reduced memory delivering 3,200 MT/s throughput for mission-critical server deployments.
The Samsung M386AAG40EM3-CWE is a 128GB DDR4 LRDIMM engineered for large-scale enterprise infrastructure requiring maximum memory density without sacrificing stability. Built on Samsung's advanced 3DS (Three-Dimensional Stacked) DRAM technology, this module operates at DDR4-3200 speeds with full ECC support for single-bit error correction and multi-bit error detection. The 8Rx4 rank configuration and low-profile form factor fit seamlessly into dense server chassis, while the 1.2V operating voltage ensures efficiency across extended temperature ranges (0°C to 85°C). With 288-pin JEDEC compliance and RoHS certification, Samsung's M386AAG40EM3-CWE meets global environmental and compatibility standards. Storage architects and IT procurement teams rely on load-reduced DIMMs to reduce electrical stress on memory controllers, enabling stable operation in systems with 16+ memory slots per processor.
Enterprise Deployment Scenarios
- High-density virtualization and consolidated hypervisor platforms requiring 2–4TB total system memory
- Enterprise data warehousing and analytics clusters processing large in-memory datasets
- Database management systems (SQL Server, Oracle, PostgreSQL) with substantial working sets
- Cloud infrastructure and multi-tenant environments prioritizing memory scaling and error resilience
- Scientific computing and simulation workloads demanding stable, high-capacity LRDIMM configurations
Samsung's proven track record in enterprise memory manufacturing ensures long-term reliability and OEM validation across major server platforms.
