The spreadsheet categorizes the 1,331 pins into several functional groups, typically color-coded for clarity:
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.
Pins that handle high-speed data for GPUs and NVMe SSDs. AM4_Pinout.ods
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
Professional overclockers use pinout maps to perform "hard mods," such as bypassing voltage protections or measuring exact voltages directly from the socket. The spreadsheet categorizes the 1,331 pins into several
These pins supply power to different parts of the chip, such as the CPU cores (VCORE), the integrated graphics (SOC), and the memory controller.
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 is a community-sourced spreadsheet file that provides a
If a user drops a Ryzen CPU and bends or breaks a pin, the "AM4_Pinout.ods" file allows them to identify exactly what that pin does. If it's a "VSS" (ground) pin, the CPU might still function; if it's a memory channel pin, the CPU will likely fail to boot or lose half its RAM capacity.
