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.

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.
