Product Description
This Samsung M386AAG40MM2-CVF module represents the pinnacle of server memory density, offering a massive 128GB capacity in a single DDR4 Load-Reduced DIMM (LRDIMM). It operates at a high frequency of 2933MHz, delivering a PC4-23466 data rate that is essential for the most demanding enterprise workloads, such as large-scale virtualization, in-memory databases, and high-performance computing. The quad-rank (4Rx4) configuration, with x4 data width per rank, is specifically designed to maximize memory bandwidth and capacity in systems that support it. LRDIMMs are distinguished by their use of a memory buffer chip, which isolates the memory controller from the DRAM devices. This buffer significantly reduces the electrical load on the memory controller, allowing for much higher memory capacities per channel and per system compared to standard RDIMMs. This makes LRDIMMs the preferred choice for servers requiring the absolute maximum amount of RAM. The module operates at a CAS Latency of CL21 and a standard voltage of 1.2V, balancing performance with power efficiency. Crucially, it incorporates ECC (Error-Correcting Code) functionality, providing enhanced data integrity and system stability, which is non-negotiable in critical server environments. This 128GB DDR4 LRDIMM is engineered for the most advanced server platforms that demand extreme memory capacity and reliability.
