Description
The Dell A21427993 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, specifically designed to boost the performance of compatible Dell server and workstation platforms. Operating at a speed of 1333MHz, this module provides a significant increase in data transfer rates compared to lower-speed memory, leading to faster application loading and improved system responsiveness. The RDIMM form factor includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in server environments. This memory module features a 2Rx4 rank configuration, indicating two ranks of memory chips, each with four data bits per chip. This configuration is common in server memory and contributes to its performance and capacity. With a CAS Latency (CL) of 9, it offers a balance between speed and timing, ensuring efficient data retrieval. The module is designed to be compatible with systems that support DDR3 1333MHz RDIMMs, making it a suitable upgrade for enhancing multitasking capabilities and overall system throughput. Upgrading system memory with modules like the Dell A21427993 is a cost-effective way to improve the performance of servers and workstations, especially those running memory-intensive applications or virtualized environments. Ensuring compatibility with the specific Dell system's motherboard and chipset is crucial for proper installation and optimal performance. This 4GB module is a reliable component for maintaining and enhancing the operational efficiency of enterprise computing infrastructure.
