Am4 Pinout Diagram Exclusive Direct

: Comprehensive 52-page block diagrams and pinout lists are available on

The AM4 socket (LGA/μPGA — actually a with pins on the processor, contacts on the socket) is AMD’s unified infrastructure for Ryzen™, Athlon™, and A-series APUs from 2017 to 2022. Unlike Intel’s LGA, AM4 places pins on the CPU substrate. This paper provides an exclusive, detailed pinout of the AM4 socket (Socket 1331), organized by function: power delivery, DDR4 memory channels, PCIe lanes, FCH (chipset) communication, and auxiliary signals. We include the physical pin mapping (A1–E32, plus inner grid), critical differences between CPU generations, and warnings for reverse-engineering or custom motherboard design. am4 pinout diagram exclusive
