Product Description
The Samsung M386A8K40CM2-CTD is a premium 64GB LRDIMM (Load-Reduced Dual In-line Memory Module) engineered for the most demanding server and workstation environments. This module utilizes DDR4 SDRAM technology, offering significant improvements in speed, power efficiency, and density over previous generations. With a substantial capacity of 64GB, it is ideal for memory-intensive applications such as large-scale virtualization, in-memory databases, high-performance computing (HPC), and complex data analytics. The module operates at a frequency of 2666MHz, providing high bandwidth crucial for applications that require rapid data processing. The CAS Latency (CL) of 19, combined with the DDR4 standard, ensures efficient data retrieval. The 4Rx4 rank configuration signifies a quad-rank design, which allows for greater memory density and potentially improved performance in systems that can leverage multiple ranks per memory channel. LRDIMMs are specifically designed to reduce the electrical load on the memory controller, enabling systems to support higher capacities and more memory modules than standard RDIMMs. Furthermore, this memory module features ECC (Error-Correcting Code) functionality, which is essential for maintaining data integrity in critical server operations. ECC memory can detect and correct common types of internal data corruption, preventing system crashes and data loss. The M386A8K40CM2-CTD is built to Samsung's high standards, ensuring reliability, stability, and compatibility with a wide range of server platforms that support DDR4 LRDIMMs.
