Product Description
The Dell A4051421 is a high-capacity 4GB DDR3 Registered DIMM (RDIMM) memory module, engineered for mission-critical server and workstation applications. It operates at a speed of 1066MHz (PC3-8500), providing substantial bandwidth for data-intensive operations. The RDIMM design incorporates a register chip that buffers address and command signals, enhancing signal integrity and enabling support for larger memory configurations and improved system stability, particularly in multi-processor environments. This module features a unique 4Rx4 configuration, indicating quad ranks, with each rank composed of four memory chips. This configuration is often found in high-density server memory modules and can offer performance advantages by allowing the memory controller to interleave operations across multiple ranks. The module operates with a CAS Latency (CL) of 7, ensuring efficient data access. Crucially, it includes ECC (Error-Correcting Code) capabilities, which are vital for detecting and correcting memory errors on the fly, thereby safeguarding data integrity and ensuring system uptime in demanding enterprise settings. Operating at a standard 1.5V, this 4GB DDR3-1066MHz ECC RDIMM module is designed for optimal compatibility and reliability within Dell's server and workstation ecosystem. Its robust specifications, including quad-rank architecture and ECC support, make it suitable for virtualization, database management, scientific computing, and other applications where data accuracy and system stability are paramount. This memory module represents a significant upgrade for systems requiring enhanced performance and data protection.
