About the Samsung 128GB DDR4 LRDIMM - DDR4 (M386A8K43CM3-CTD)
Samsung DDR4 LRDIMM 128GB at 2666 MT/s (PC4-21300) delivers enterprise-class memory density and bandwidth for next-generation server architectures. The M386A8K43CM3-CTD module combines Samsung's proven DDR4 technology with Load-Reduced DIMM architecture, enabling higher channel population and superior thermal efficiency in data center deployments. With 3DS TSV (Three-Dimensional Stacking with Through-Silicon Vias) die technology, this octal-rank LRDIMM maximizes memory per socket while maintaining signal integrity across Intel Xeon Scalable platforms including Skylake-SP and Cascade Lake-SP processors.
Storage architects, infrastructure engineers, and IT procurement teams select the Samsung M386A8K43CM3-CTD for mission-critical workloads requiring 128GB capacity in a single module footprint. The 72-bit bus width includes full ECC protection, registered buffering (RCD + DB), and JEDEC-compliant SPD functionality—essential safeguards for financial services, healthcare analytics, and high-performance computing environments. At 1.2V operating voltage with CAS latency 19-19-19, this configuration balances performance and power consumption across demanding multi-socket systems where memory density directly impacts total cost of ownership. The 0°C to 85°C operating range ensures reliability in diverse data center cooling scenarios.
