Description
The Samsung M386AAK40B40-CUC5 is a 128GB LRDIMM memory module, specifically designed to meet the rigorous demands of modern enterprise servers and high-performance computing environments. Its DDR4 technology provides enhanced bandwidth and power efficiency compared to previous generations, making it an ideal choice for memory-intensive applications such as large-scale databases, virtualization, and scientific simulations. The module features an 8Rx4 configuration, indicating 8 ranks with 4 bits per rank, which allows for higher density and improved performance by distributing the memory access across multiple ranks. The 2400MHz clock speed translates to a theoretical peak bandwidth of 19.2 GB/s per module, significantly accelerating data processing and application responsiveness. The CL17 CAS latency ensures timely data retrieval, balancing speed with stability. As a Load-Reduced DIMM (LRDIMM), this module incorporates an 8-bit buffer chip that reduces the electrical load on the memory controller. This feature is crucial for systems requiring a large number of memory modules, enabling higher memory capacities and improved signal integrity. The inclusion of ECC (Error-Correcting Code) further enhances system reliability by detecting and correcting single-bit errors, preventing data corruption and system crashes.
