Samsung M386A8K40BMB-CPBOQ 64GB DDR4-2133MHz LRDIMM 4Rx4 CL15 Memory

Product Description

This Samsung memory module, SKU M386A8K40BMB-CPBOQ, is a substantial 64GB DDR4 Load-Reduced DIMM (LRDIMM). LRDIMMs are specifically engineered for enterprise servers that require extremely high memory capacities and improved signal integrity. Unlike RDIMMs, LRDIMMs use a memory buffer chip that isolates the memory controller from the DRAM chips, significantly reducing the electrical load. This allows for more memory modules to be installed per channel and enables higher overall system memory configurations, making it ideal for memory-intensive applications like large databases, in-memory analytics, and high-density virtualization. The module operates at a frequency of 2133MHz (PC4-17000R), providing a robust data transfer rate suitable for demanding server workloads. It features a CAS latency of CL15, which is a relatively low latency for DDR4 memory, contributing to efficient data access. The 4Rx4 configuration indicates that the module is quad-ranked, with each rank composed of x4 DRAM chips. This quad-rank design, combined with the LRDIMM architecture, allows for maximum memory density and can offer performance benefits through advanced rank interleaving techniques. Designed for the highest levels of reliability and data integrity in enterprise environments, the M386A8K40BMB-CPBOQ supports Load-Reduced ECC. This advanced ECC functionality works in conjunction with the LRDIMM architecture to ensure data accuracy and system stability even under extreme memory loads. This 64GB LRDIMM is a premium choice for servers that push the boundaries of memory capacity and performance, ensuring dependable operation for critical business applications.
