Description

The Dell A21427986 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation environments that require high capacity and performance. It operates at a speed of 1066MHz, providing substantial bandwidth for intensive applications, multitasking, and data-intensive workloads. The dual-rank (2Rx4) configuration enhances memory performance by allowing the memory controller to access different ranks of memory simultaneously, leading to improved throughput and reduced latency. This module features a CAS Latency of CL7, which signifies fast response times for data requests, crucial for maintaining system responsiveness under heavy load. The RDIMM architecture includes onboard registers that buffer command and address signals, lessening the electrical burden on the memory controller. This design enables systems to support a greater number of memory modules, facilitating higher overall system memory capacity and enhanced stability. Built for reliability, the Dell A21427986 incorporates Error-Correcting Code (ECC) technology. ECC memory automatically detects and corrects single-bit errors, preventing data corruption and ensuring the integrity of critical operations. This makes it an indispensable component for mission-critical servers and workstations where uptime and data accuracy are paramount. Operating at a standard 1.5V, it ensures broad compatibility with DDR3-based Dell server and workstation platforms.
