Product Description
The Dell A21327990 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, specifically designed for Dell servers and workstations that demand high reliability and performance. Operating at 1333MHz (PC3-10600) with a CAS Latency (CL) of 9, this module offers a good balance of speed and responsiveness for enterprise workloads. Its 2Rx4 (Dual Rank x4) configuration can enhance performance by allowing the memory controller to access different ranks simultaneously. As a Registered DIMM, this module includes onboard registers that buffer memory commands and addresses. This reduces the electrical load on the memory controller, enabling systems to support higher memory capacities and improving overall stability, which is critical for server environments. The inclusion of ECC (Error-Correcting Code) technology is vital for data integrity, as it automatically detects and corrects single-bit errors, preventing data corruption and system crashes. This 4GB DDR3 RDIMM is an essential component for upgrading or maintaining Dell PowerEdge servers and Precision workstations. It is suitable for a wide range of applications, including virtualization, database management, and complex scientific computations, where consistent performance and data accuracy are paramount. Ensuring compatibility with your specific Dell system is recommended before installation.
