Product Description
The Crucial CT16G4RFD4266 is a 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered to deliver enhanced performance and reliability for server environments. Operating at a frequency of 2666MHz, it provides faster data transfer rates compared to lower-speed modules, which is beneficial for memory-intensive server workloads. The RDIMM design includes onboard registers that buffer command and address signals, reducing the electrical load on the memory controller and enabling higher memory densities and improved system stability, especially in systems populated with many DIMMs. This module features a CAS Latency (CL) of 19, indicating the number of clock cycles required to access data after a command is issued. Its 2Rx4 rank organization signifies two ranks, each with a 4-bit data width per chip, contributing to its overall bandwidth. Crucially, it supports ECC (Error-Correcting Code) functionality, which is essential for servers to detect and correct single-bit errors, thereby preventing data corruption and ensuring system uptime and data integrity. With its combination of 16GB capacity, 2666MHz speed, and ECC support, the Crucial CT16G4RFD4266 is well-suited for a variety of server applications, including virtualization, database hosting, cloud computing, and enterprise resource planning (ERP) systems. It is designed to meet the demanding requirements of modern data centers for performance, capacity, and reliability.
