Product Description
The Samsung M386AAG40MM2-CVFBQ is a premium 128GB Load-Reduced DIMM (LRDIMM) module, engineered for the most demanding server and high-performance computing environments. LRDIMMs utilize a memory buffer chip to reduce the electrical load on the memory controller, enabling higher memory densities and improved signal integrity. This is essential for systems requiring vast amounts of RAM, such as large-scale virtualization, in-memory databases, and complex scientific simulations. Operating at a high speed of 2933MHz (PC4-23466), this DDR4 module provides exceptional bandwidth, significantly accelerating data access and processing for memory-intensive applications. The 4Rx4 rank organization signifies a highly dense module, with four ranks, each composed of 4 bits. This configuration maximizes the number of memory chips on the module, contributing to its substantial 128GB capacity and enabling higher system memory configurations. Furthermore, the M386AAG40MM2-CVFBQ includes Error-Correcting Code (ECC) functionality, which is critical for maintaining data integrity in mission-critical server applications. ECC memory can detect and correct single-bit errors, preventing data corruption and system crashes. This, combined with its high capacity and speed, makes it an ideal choice for enterprise-grade servers and workstations where reliability, performance, and scalability are paramount. The module operates at a standard DDR4 voltage of 1.2V.
