Product Description
The Samsung M386A8K40DM2-CTD is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM) memory module, specifically engineered for server platforms that require extensive memory resources. Operating at a speed of 2666MHz, this module provides substantial bandwidth to support memory-intensive applications, virtualization, large databases, and complex scientific simulations. The LRDIMM architecture includes a memory buffer chip that reduces the electrical load on the memory controller, enabling systems to support higher memory capacities and more DIMMs per channel than standard RDIMMs or UDIMMs. This module features a CAS Latency (CL) of 19, which, in conjunction with its 2666MHz frequency, offers a performance profile suitable for enterprise workloads. The 4Rx4 configuration indicates that it is a quad-rank module utilizing x4 DRAM chips, allowing for very high density within a single DIMM. This density is crucial for servers designed to maximize RAM capacity within a limited number of slots. As a component from Samsung, a leading memory manufacturer, the M386A8K40DM2-CTD is built to rigorous standards of quality and reliability, ensuring stability and performance in demanding server environments. It is an ideal choice for upgrading servers in data centers, cloud computing environments, and high-performance computing (HPC) clusters where maximum memory capacity is a key requirement for achieving optimal performance and scalability.
