About the Samsung 128GB DDR4 LRDIMM M386AAG40MM3-CRC
The Samsung M386AAG40MM3-CRC is a 128GB DDR4 LRDIMM optimized for Intel Xeon Scalable and AMD EPYC multi-socket server architectures, delivering exceptional memory density across high-channel-count platforms. This load-reduced DIMM minimizes electrical loading on memory buses, enabling stable operation in dense server configurations where standard UDIMMs would introduce signal integrity challenges. Enterprise data center teams, storage architects, and AI infrastructure specialists rely on Samsung's enterprise-grade memory to maximize per-socket capacity while maintaining stringent reliability standards.
Built to JEDEC DDR4 LRDIMM specifications, the M386AAG40MM3-CRC operates at 2400 MT/s with full ECC protection, ensuring data integrity in mission-critical workloads. Its octal-rank (8Rx4) configuration and x4 DRAM organization enable efficient memory scaling for virtualization, analytics, and high-performance computing environments. The module's 1.2V operating voltage aligns with DDR4 efficiency targets, reducing thermal footprint in fully populated server chassis. With a standard 31.25mm height and 288-pin interface, this Samsung module integrates seamlessly into compatible server platforms while maintaining compatibility with existing infrastructure investments. CAS latency of 17 and symmetric timings (17-17-17) balance performance and stability across demanding mixed workloads. The extended operating temperature range (0°C to 85°C) accommodates diverse data center cooling strategies. Samsung's proven manufacturing heritage ensures consistent quality and long-term availability for large-scale deployments. Whether refreshing legacy Xeon E5 or scaling modern Xeon Platinum ecosystems, the M386AAG40MM3-CRC delivers reliable, high-capacity memory expansion.
