Description
The ADATA AD4R266638G19-B is an 8GB DDR4 memory module designed for server and workstation environments. It operates at a frequency of 2666MHz, identified by its PC4-21300 rating, and features a CAS Latency (CL) of 19. This module is a Registered DIMM (RDIMM), which includes an onboard register to buffer command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved stability in multi-processor systems. The 1Rx8 designation indicates that it is a single-rank module with eight memory chips per rank. This configuration is common for many server applications. As an ECC (Error-Correcting Code) module, it provides enhanced data integrity by detecting and correcting single-bit errors, which is crucial for preventing data corruption and system crashes in critical operations. With its 288-pin connector, this module is compatible with standard DDR4 DIMM slots found in modern servers and high-end workstations. ADATA is a reputable manufacturer of memory and storage solutions, ensuring quality and reliability. This 8GB RDIMM is suitable for upgrading existing server memory or for building new systems that require dependable and efficient memory performance.
