Pins that handle high-speed data for GPUs and NVMe SSDs.
Professional overclockers use pinout maps to perform "hard mods," such as bypassing voltage protections or measuring exact voltages directly from the socket. AM4_Pinout.ods
The spreadsheet categorizes the 1,331 pins into several functional groups, typically color-coded for clarity: 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 It serves as a vital technical reference for
These pins supply power to different parts of the chip, such as the CPU cores (VCORE), the integrated graphics (SOC), and the memory controller.
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.
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
