is a community-sourced spreadsheet file that provides a comprehensive mapping of the 1,331 pins found on AMD's AM4 CPU socket. It serves as a vital technical reference for hardware enthusiasts, overclockers, and engineers looking to understand the physical and electrical layout of Ryzen processors. Purpose and Origin

These pins supply power to different parts of the chip, such as the CPU cores (VCORE), the integrated graphics (SOC), and the memory controller. AM4_Pinout.ods

A large block of pins dedicated to communicating with RAM. These are sensitive to physical damage; a single bent pin here can "kill" a memory channel. is a community-sourced spreadsheet file that provides a

The most numerous pins, providing a common return path for electrical current and helping to shield signal pins from interference. A large block of pins dedicated to communicating with RAM

Pins that handle high-speed data for GPUs and NVMe SSDs.

The spreadsheet categorizes the 1,331 pins into several functional groups, typically color-coded for clarity:

It provides a visual representation of how modern "System on a Chip" (SoC) designs prioritize communication, showing how much physical space is dedicated to memory and PCIe compared to raw power. Technical Layout
