The most complete is from AMD’s BKDG (BIOS and Kernel Developer Guide) for each family – but only under NDA.
The pins on an AM4 processor are generally divided into several critical functional zones:
I’m unable to create actual images or diagrams, but I can give you a of the AMD AM4 socket. This covers the key functional groups so you can draw it or reference it against a real diagram.
: Data pairs for the graphics card or NVMe drives. A break here might drop your GPU from x16 to x8 mode or prevent it from being detected. Handling Damaged Pins If you find a bent or broken pin: Identify the pin Assess the risk cap V cap S cap S
SATA signals (up to 4 ports) are also routed through the CPU to the FCH. Look for pins SATA_TX_P/N and SATA_RX_P/N around rows V and W.
