Dell A21627981 8GB DDR3-1066MHz RDIMM 2Rx4 CL7 Memory

Product Description

The Dell A21627981 is a high-capacity 8GB DDR3 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation environments. It operates at a speed of 1066MHz, providing ample bandwidth for memory-intensive applications and multitasking. The RDIMM architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This allows for higher memory densities and improved system stability, which are critical for enterprise-grade hardware. This module features a 2Rx4 rank configuration, indicating it is dual-rank with each rank organized by x4 (4-bit) data width. Dual-rank modules can offer performance advantages by enabling the memory controller to access different ranks concurrently. The CAS Latency (CL) is 7, representing the number of clock cycles required for the memory to respond to a column address command, contributing to its overall responsiveness. It also supports ECC (Error-Correcting Code) functionality, which is essential for detecting and correcting single-bit memory errors, thereby enhancing data integrity and system reliability. With its 240-pin connector and standard 1.5V operating voltage, the Dell A21627981 is compatible with a wide range of DDR3-enabled server and workstation platforms that specifically support registered ECC memory. This memory module is an ideal choice for upgrading existing systems or populating new servers that require increased memory capacity and robust performance for virtualization, database management, and other memory-intensive workloads.
