Description
The Samsung M386AAK40B40-CUC4 is an exceptionally high-capacity 128GB DDR4 Load-Reduced Dual In-line Memory Module (LRDIMM), engineered for the most demanding enterprise server environments. This module is designed to maximize memory density and performance, enabling systems to handle massive datasets and complex virtualized workloads. The LRDIMM architecture is essential for achieving such high capacities by reducing the electrical load on the memory controller, thereby improving signal integrity and system stability. Operating at a speed of 2400MHz (PC4-19200) with a CAS Latency of CL17, this module delivers substantial memory bandwidth crucial for high-performance computing and data-intensive applications. The 8Rx4 configuration signifies an octal-rank design, where each rank is composed of x4 DRAM devices. This advanced configuration is optimized for servers that require the utmost in memory capacity and throughput, pushing the boundaries of what is possible with DDR4 memory. Equipped with Registered ECC (Error-Correcting Code), this 128GB LRDIMM ensures exceptional data integrity and system reliability, which are paramount in mission-critical server operations. The 1.2V operating voltage aligns with DDR4 standards for power efficiency, helping to manage thermal output in dense server configurations. This module is an ideal choice for cutting-edge servers used in big data analytics, large-scale virtualization, AI/ML training, and other applications that demand vast amounts of memory.
