Product Description
The Dell A21256957 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, distinguished by its 4Rx4 configuration. This means it is quad-ranked, with each rank utilizing x4 DRAM chips. Quad-rank modules are designed to maximize memory density within a server's memory slots, allowing for higher total system memory capacities, which is crucial for memory-intensive applications like virtualization, large databases, and high-performance computing. Operating at 1066MHz (PC3-8500R) with a CAS Latency of CL7, this module offers a solid performance profile suitable for enterprise workloads. The inclusion of a register, characteristic of RDIMMs, helps to alleviate the electrical load on the memory controller, enabling the system to support a greater number of memory modules and achieve higher overall memory capacities. This makes it an ideal choice for servers where maximum memory footprint is a requirement. As with other RDIMMs, the A21256957 supports ECC (Error-Correcting Code) functionality. ECC memory is essential in server environments for detecting and correcting memory errors on the fly, significantly reducing the risk of data corruption and system instability. This module is engineered for compatibility with Dell servers and other enterprise systems that require robust, high-capacity, and reliable DDR3 memory solutions.
