About the Samsung 32GB DDR4 LRDIMM - DDR4 (M386A4K43CM3-CTD)
The Samsung M386A4K43CM3-CTD is a 32GB DDR4 LRDIMM with quad-rank (4Rx4) configuration and full ECC support, purpose-built for Intel Xeon Scalable and select AMD EPYC server platforms. This load-reduced DIMM architecture minimizes electrical stress on the memory controller, enabling higher density deployments in multi-socket data center environments where storage architects and infrastructure teams demand maximum reliability and capacity per slot.
Operating at 2666 MT/s (PC4-21300) with registered iMB buffering and 1.2V efficiency, the Samsung DDR4 LRDIMM delivers proven performance for virtualization, databases, and high-throughput computing workloads. The 288-pin module features 19-19-19 CAS latency timing and full JEDEC DDR4 LRDIMM compliance, ensuring seamless integration into existing Skylake-SP and Cascade Lake-SP deployments. With Error-Correcting Code built in, the M386A4K43CM3-CTD protects mission-critical data integrity across extended temperature ranges (0°C to 85°C). Samsung's reputation for enterprise-grade reliability makes this module a trusted choice for organizations scaling their server infrastructure.
