Product Description
The Dell A1551886 is a 4GB DDR2 Registered DIMM (RDIMM) memory module designed to enhance the performance and capacity of compatible Dell server platforms. With a memory speed of 667MHz, it offers a notable performance improvement over slower DDR2 modules, making it suitable for memory-intensive applications and multitasking environments. This RDIMM features a 2Rx4 configuration, indicating two ranks of memory with four chips per data path. The registered nature of the module helps to reduce the electrical load on the memory controller, enabling higher memory configurations and improving overall system stability. This is particularly important in server environments where reliability and uptime are paramount. The module also supports ECC (Error-Correcting Code) functionality, which is essential for maintaining data integrity in critical server operations by detecting and correcting memory errors. The CL5 CAS latency is a measure of the delay between the memory controller requesting data and the data being available, and at 667MHz, this latency is optimized for performance. This memory module is an excellent choice for upgrading or populating memory in Dell PowerEdge servers that support DDR2 RDIMMs.
