Important Note: Do not memorize individual pin functions (like "pin A12 is VDD"). Motherboard traces and the socket's internal wiring handle that. For you, the only critical "pinout" knowledge is identifying Pin 1.

Look at the bottom of your Ryzen CPU. You will see a small gold triangle printed on the corner of the PCB (Printed Circuit Board). Locate the matching triangle on the CPU socket on the motherboard. This is Pin 1. am4 pinout diagram install

A full AM4 pinout diagram is complex, but here are the critical zones:

Crucial Warning: Do not use a multimeter on the pads of a new motherboard unless you are diagnosing a failure. The pinout diagram is for visual reference to identify bent pins, not for probing live voltage. Looking at the CPU with the gold triangle

You did the install, but the PC won't POST (Power On Self Test). Use the pinout logic to diagnose.
