1. Introduction The Dell OptiPlex 740 is a business-class desktop introduced around 2006–2007. It was notable for being one of the first OptiPlex models to use AMD processors (Socket AM2) instead of Intel, featuring AMD Athlon 64 X2, Sempron, or early Phenom CPUs. Understanding its motherboard layout is essential for troubleshooting, component replacement, and upgrading legacy systems. Dell Optiplex 740 Motherboard Diagram
