Am4_pinout.ods Official

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

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

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

Including pins for thermal monitoring, reset signals, and clock generators. Why This File is Used

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 pins are arranged in a grid with specific "keying" (missing pins in certain corners) to ensure the CPU can only be inserted in one orientation. The spreadsheet typically mimics this grid, using coordinates (e.g., A1, AJ39) so users can physically locate a pin on the bottom of their processor by matching it to the digital map.

Pins that handle high-speed data for GPUs and NVMe SSDs. Including pins for thermal monitoring, reset signals, and

The AM4 socket, introduced in 2016, moved AMD to a Pin Grid Array (PGA) where the pins are on the processor rather than the motherboard. Because AMD does not publicly release exhaustive, pin-by-pin documentation to the general public, the community—primarily through platforms like Reddit and Twitter —reverse-engineered the layout. The .ods (OpenDocument Spreadsheet) format is used to make this data accessible via free software like LibreOffice or Google Sheets. Key Components of the Pinout
