Am4 Pinout Diagram Exclusive |verified| -

You dropped your Ryzen CPU. Now 6 pins on the bottom-right corner (PCIe zone) are bent at a 45-degree angle. Here is the exclusive repair protocol using the pinout:

| Rail | Pin Count | Typical Pin Prefix | Notes | |---------------|-----------|--------------------|----------------------------------------| | VDD (Core) | ~240 | Axx, Bxx, etc. | Distributed across inner rows | | VDD_SOC | ~40 | Cxx, Dxx | Uncore (iMC, IF, PCIe controller) | | VDD_18 (1.8V) | 12 | E1–E6, E26–E31 | Standby/auxiliary | | VDD_33 (3.3V) | 8 | A1–A4, A32–A35 | Used for FCH/SPI/GPIO | | VSS (Ground) | ~400 | Everywhere | Balance signal return |

The remaining pins govern the foundational startup sequence and basic input/output operations of the machine.

The AM4 socket utilizes highly specific zones for electrical layout.Pins are categorized into functional groups to manage data transfer. You dropped your Ryzen CPU

The AM4 platform provides 24 usable PCIe lanes directly from the CPU package.

: Responsible for GPU and NVMe communication. Damage here can cause lower PCIe speeds or undetected drives.

Make sure the golden triangle aligns with the corner marking on the plastic socket. | Distributed across inner rows | | VDD_SOC
