Description
The Samsung M393A8G40MB2-CTD7Y is a high-capacity 64GB Registered Dual In-line Memory Module (RDIMM) utilizing DDR4 SDRAM technology. Designed for server and workstation environments, this module operates at a speed of 2666MHz, corresponding to the PC4-21300 standard. The dual-rank x4 (2Rx4) configuration allows for increased memory bandwidth and performance by accessing data in smaller, more efficient chunks. This RDIMM features Error-Correcting Code (ECC) functionality, which detects and corrects common types of internal data corruption, enhancing system stability and reliability. The registered nature of the module helps reduce electrical load on the memory controller, enabling higher memory capacities and improved signal integrity, which is crucial for large-scale server deployments. The CAS Latency (CL) is rated at 19, indicating the number of clock cycles it takes for the memory to respond to a column address command. Operating at a standard voltage of 1.2V, this 64GB DDR4 RDIMM is compatible with a wide range of server platforms that support DDR4 memory. Its specifications make it suitable for memory-intensive applications such as virtualization, database management, scientific computing, and large-scale data analysis, where high capacity, speed, and reliability are paramount.
