Product Description
This Samsung M386AAG40AM3-CWEZQ module is a high-capacity 128GB DDR4 Load-Reduced DIMM (LRDIMM) operating at 3200MHz (PC4-25600). LRDIMMs are engineered for servers that demand the highest possible memory capacities, utilizing a specialized buffer chip to mitigate the electrical load on the memory controller. This design enables systems to support a greater number of DIMMs per channel, facilitating massive memory configurations. The module is specified as 4Rx4, indicating a quad-rank design with four memory banks per rank. This configuration, combined with the LRDIMM architecture, is optimized for achieving maximum memory density and performance in advanced server platforms. The CAS Latency (CL) is 22, which is standard for DDR4 modules at this speed, offering a good balance between high frequency and data access times. As a Registered ECC (Error-Correcting Code) module, it provides enhanced data integrity and system stability, which are critical for mission-critical server environments. The standard 1.2V operating voltage ensures broad compatibility. The M386AAG40AM3-CWEZQ is an essential component for data-intensive server applications such as large-scale virtualization, in-memory databases, high-performance computing (HPC), and big data analytics, where maximizing RAM capacity is a primary requirement.
