Product Description
This Samsung 256GB DDR4 memory module, SKU M386ABG40M50-CYFC0, represents a pinnacle of memory density and performance for server applications. Operating at a high frequency of 2933MHz, it delivers substantial bandwidth crucial for demanding workloads such as large-scale virtualization, in-memory databases, and high-performance computing. The Load-Reduced DIMM (LRDIMM) architecture incorporates an 8-rank design (8Rx4), which significantly increases the number of memory modules that can be supported per channel by buffering address and command signals, thereby enabling extremely high total system memory capacities. The LRDIMM technology is specifically engineered to overcome the electrical limitations of traditional RDIMMs and UDIMMs, allowing servers to achieve maximum memory configurations. This makes the M386ABG40M50-CYFC0 an ideal choice for systems requiring vast amounts of RAM to handle massive datasets and complex computations. The module also includes Error-Correcting Code (ECC) capabilities, ensuring data integrity and system reliability, which is non-negotiable in enterprise environments. With a CAS Latency (CL) of 21, this module balances its high capacity and speed with acceptable latency for server operations. The standard 1.2V operating voltage ensures compatibility with DDR4 server platforms. For organizations pushing the boundaries of data processing and requiring the utmost in memory capacity and stability, this 256GB LRDIMM is a critical component.
