Dell A3721505 8GB DDR3-1066MHz RDIMM 4Rx4 CL7 Memory

Product Description

The Dell A3721505 is an 8GB DDR3 Registered DIMM (RDIMM) memory module designed for specific server configurations that benefit from higher memory density and rank interleaving. Operating at 1066MHz (PC3-8500), this module provides a solid foundation for memory-intensive server tasks. The CAS Latency of CL7 offers relatively quick response times for its speed class, contributing to efficient data access. This module is characterized by its Quad Rank (4Rx4) configuration. Quad Rank DIMMs utilize four ranks of DRAM chips, which can allow for higher memory capacities per module and potentially improve performance through advanced rank interleaving techniques supported by the server's memory controller. As an RDIMM, it includes an onboard register to buffer command and address signals, reducing the load on the memory controller and enabling greater scalability in terms of total installed memory. Crucially, the A3721505 supports ECC (Error-Correcting Code), providing essential data integrity and reliability for server environments. ECC memory automatically detects and corrects single-bit errors, minimizing the risk of data corruption and system downtime. This feature is vital for mission-critical applications, databases, and virtualization. The 4Rx4 configuration is often required by specific server models to achieve maximum memory configurations or optimal performance, making this module a specialized but important component for compatible Dell systems.
