Product Description
The Crucial CT16G4RFD8266 is engineered to meet the rigorous demands of modern server environments. Its 16GB capacity provides ample room for large datasets and complex applications, while the DDR4 technology ensures higher bandwidth and improved power efficiency compared to previous generations. This module features a 2Rx8 configuration, indicating it is dual-ranked with an eight-bit memory chip organization. This design can offer performance benefits in certain server workloads by allowing the memory controller to access different ranks independently. The Registered DIMM (RDIMM) format includes an onboard register that buffers address and command signals, reducing electrical load on the memory controller and enabling higher memory capacities and improved signal integrity, crucial for system stability. Operating at 2666MHz with a CAS Latency of CL19, the CT16G4RFD8266 delivers a robust performance profile suitable for a wide array of enterprise applications, including virtualization, database management, and high-performance computing. The inclusion of ECC (Error-Correcting Code) is paramount for servers, as it detects and corrects single-bit errors on the fly, preventing data corruption and system crashes, thereby ensuring the reliability and uptime essential for business-critical operations.
