Product Description
The Dell A21427980 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for server and workstation environments. The 'Registered' designation means it includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and greater stability in systems with many memory modules. This makes it ideal for mission-critical applications where reliability is paramount. This module operates at a speed of 1066MHz, providing efficient data transfer rates suitable for demanding server workloads. It also features Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, preventing data corruption and system crashes. The 2Rx4 configuration indicates a dual-rank module with four data bits per chip, offering improved performance and efficiency in certain server memory architectures. With a CAS Latency (CL) of 7, the Dell A21427980 offers a balance between speed and latency for server applications. Its 8GB capacity provides a substantial amount of memory for virtualization, database operations, and other memory-intensive tasks commonly found in enterprise environments. Compatibility should always be confirmed with the specific server or workstation model's documentation.
