Dell A21259048 8GB DDR3-1066MHz RDIMM 4Rx4 CL7 Memory

Product Description

The Dell A21259048 is an 8GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module, specifically a Registered DIMM (RDIMM), operating at a speed of 1066MHz (PC3-8500). This module is engineered for server and high-performance computing environments where substantial memory capacity and reliable operation are critical. The RDIMM format includes an onboard register that buffers the command and address signals, reducing the electrical load on the memory controller. This allows for greater memory scalability and improved system stability, which are essential characteristics for enterprise servers. The defining feature of the A21259048 is its 4Rx4 rank configuration. This indicates a quad-rank module where each rank is composed of DRAM chips with a 4-bit data interface (x4). Quad-rank modules provide the highest memory density and can offer significant performance benefits through advanced interleaving techniques, allowing the memory controller to access multiple ranks and banks concurrently. This configuration is particularly advantageous for memory-intensive applications such as large databases, virtualization platforms, and complex data analytics. With a CAS Latency (CL) of 7, the module provides a fast response time to memory requests, contributing to overall system efficiency. This 8GB DDR3-1066MHz RDIMM is designed to meet the rigorous demands of modern data centers and enterprise IT infrastructure, offering a robust solution for memory upgrades in compatible Dell PowerEdge servers and other systems. It ensures that applications have the necessary memory resources to perform optimally, preventing bottlenecks and enhancing productivity.
