Pins that handle high-speed data for GPUs and NVMe SSDs.
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 AM4_Pinout.ods
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.
