The AM4 Pinout Diagram: An Exclusive Deep Dive into AMD’s Legendary Socket am4 pinout diagram exclusive

Here is where the exclusive diagram pays off. You have a dead PC. You pull the CPU and see bent pins. For the highest resolution, annotated AM4 pinout map

| Use | Lanes | Pin range | Notes | |------------|------------|----------------|-------------------------------------| | PEG (x16) | 16 lanes | D1–D10, C1–C6 | Direct to PCIe x16 slot 0 | | M.2 CPU | 4 lanes | B1–B4 | For primary NVMe (CPU direct) | | GPP (chipset) | 4 lanes | A31–A35 | To X370/B350/X470/B550/A520 FCH | You pull the CPU and see bent pins

A pinout diagram is a map that identifies exactly which pin corresponds to which function. Without it, you cannot trace a signal from the CPU to the motherboard components.
