About the Samsung 128GB DDR4 LRDIMM M386AAG40EM3-CTD

Samsung 128GB DDR4 LRDIMM (M386AAG40EM3-CTD) delivers enterprise-grade memory for Intel Xeon Scalable processors (Skylake-SP, Cascade Lake-SP), featuring load-reduced DIMM architecture optimized for high-density, multi-socket server deployments. Operating at 2666 MT/s (PC4-21300) with 1.2V efficiency, this octal-rank module integrates ECC protection and advanced thermal management, reducing electrical load on memory channels while maintaining data integrity across demanding workloads.

The M386AAG40EM3-CTD combines Samsung's reliability with LRDIMM benefits—supporting up to 12 DIMMs per CPU in Xeon platforms without channel degradation. Its 288-pin configuration, CAS latency-19 timing, and Serial Presence Detect (SPD) EEPROM ensure seamless BIOS recognition and plug-and-play deployment. Storage architects and IT procurement teams favor this module for right-sizing large-capacity memory pools while maintaining system stability. Contact Omnixon Global for a detailed RFQ.

Enterprise Deployment Scenarios

  • High-density virtualization hosts requiring 512GB–2TB memory footprints across 2–4 sockets per server
  • In-memory analytics and data warehouse appliances leveraging sustained random-access performance
  • HPC and machine learning infrastructure where ECC protection prevents silent data corruption
  • Cloud infrastructure and containerized workloads demanding consistent latency and throughput
  • Database consolidation projects migrating from smaller DIMM configurations to fewer, larger-capacity servers
