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.
Professional overclockers use pinout maps to perform "hard mods," such as bypassing voltage protections or measuring exact voltages directly from the socket.
Pins that handle high-speed data for GPUs and NVMe SSDs. 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. Key Components of the Pinout
These pins supply power to different parts of the chip, such as the CPU cores (VCORE), the integrated graphics (SOC), and the memory controller. A large block of pins dedicated to communicating with RAM
The most numerous pins, providing a common return path for electrical current and helping to shield signal pins from interference.
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 Pins that handle high-speed data for GPUs and NVMe SSDs
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.
