Product Description
This Samsung M386A8K40DM2-CTD6Y memory module is a 64GB LRDIMM (Load-Reduced Dual In-line Memory Module) specifically engineered for high-performance computing environments, primarily servers and advanced workstations. LRDIMMs are designed to allow for greater memory capacity and higher speeds in systems that support them, by reducing the electrical load on the memory controller. This particular module operates at a DDR4-2666MHz frequency, identified as PC4-21300, providing substantial bandwidth for memory-intensive applications. The module features a quad-rank (4Rx4) configuration, meaning it has four ranks of memory chips, each with an x4 data width. This architecture can offer improved performance and density compared to dual-rank modules in certain server platforms. The CAS Latency (CL) is rated at 19, indicating the number of clock cycles it takes for the memory to respond to a request. It also incorporates ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors, crucial for maintaining data integrity and system stability in mission-critical applications. Operating at a standard voltage of 1.2V, this LRDIMM is compatible with server motherboards that specifically support DDR4 LRDIMM memory and the 2666MHz speed rating. Its high capacity and advanced features make it suitable for demanding tasks such as large-scale data analysis, virtualization, complex simulations, and high-performance database management. Always ensure system compatibility before installation, as LRDIMMs have specific motherboard requirements.
