Dell A7658529 4GB DDR3-1066MHz UDIMM 2Rx8 CL7 Memory

Product Description

The Dell A7658529 is a 4GB DDR3 Unbuffered DIMM (UDIMM) memory module, designed for standard desktop computers and some entry-level servers that do not require registered memory. It operates at a speed of 1066MHz, providing a good balance of performance and capacity for everyday computing tasks, office applications, and light multitasking. The unbuffered nature means that command and address signals are passed directly to the memory chips, which is simpler and less expensive but limits the total memory capacity and speed achievable compared to RDIMMs. This module features a 2Rx8 rank configuration, indicating it is dual-rank with each rank organized by x8 (8-bit) data width. Dual-rank configurations can sometimes offer slight performance advantages over single-rank modules. The CAS Latency (CL) is set at 7, meaning it takes 7 clock cycles to access data after a command is issued. This specification is important for overall memory responsiveness. It operates at the standard DDR3 voltage of 1.5V and uses a 240-pin connector. While UDIMMs are generally non-ECC, it's crucial to verify system compatibility as some systems might support specific UDIMM types. The Dell A7658529 is a common upgrade option for systems that support DDR3 UDIMMs, offering increased capacity to improve system responsiveness and handle more applications simultaneously. It's a cost-effective solution for enhancing the performance of compatible computing devices.
