Product Description
The Dell 311-7154 is an 8GB memory kit, comprising two 4GB DDR2 Registered DIMMs (RDIMMs), specifically designed for compatible Dell PowerEdge servers. This kit provides essential memory capacity for legacy systems that utilize DDR2 technology, operating at a frequency of 667MHz. Each 4GB module in this kit features a 2Rx4 configuration, indicating a dual-rank design with an x4 data organization per rank. This configuration is typical for server-grade memory modules of that era, balancing capacity and performance. The RDIMM architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enhancing system stability, particularly important in multi-processor server configurations. With a CAS Latency (CL) of 5, these modules offer acceptable response times for the DDR2 standard. They also support Error-Correcting Code (ECC), which is crucial for detecting and correcting memory errors to ensure data integrity and system reliability in server environments. Operating at 1.8V, this kit is a suitable option for maintaining or upgrading the memory in older Dell server infrastructure.
