Samsung M386A8K40DM2-CTD 64GB 2666 MT/s ECC LRDIMM | Server Memory

Increase memory capacity where it matters most. This Samsung 64 GB DDR4 LRDIMM is built for server environments that need large memory footprints, predictable behavior, and error correction under continuous load. With a 2,666 MHz speed rating, CL19 latency, and 1.2 V operating voltage, it fits infrastructure teams that prioritize stability and compatibility over consumer-oriented specifications. The 4Rx4 organization and ECC registered design support high-density deployment in systems that run virtualization clusters, in-memory databases, analytics engines, and other workloads that benefit from expanded RAM. As an LRDIMM, it is suited to platforms engineered for larger memory populations, helping maintain signal quality as capacity scales. For procurement teams standardizing on production memory, this module offers a clear reason to choose enterprise-grade hardware: more capacity per slot, error correction, and the electrical characteristics expected in server-class systems. It is a practical upgrade path when downtime is expensive and memory headroom directly affects application performance.
