Understanding the is essential for enthusiasts, engineers, and anyone attempting a repair on AMD’s highly successful Ryzen processors . The AM4 socket, also known as Socket 1331, was a cornerstone of PC building from 2016 until the arrival of the AM5 platform. Unlike Intel’s LGA (Land Grid Array) sockets, AM4 uses a PGA (Pin Grid Array) design, where the pins are located on the processor itself rather than the motherboard. AM4 Socket Specifications The AM4 platform consists of a

Pins are typically indexed using a coordinate system (Rows and Columns), similar to a spreadsheet (e.g., Row A through Row AZ, Column 1 through Column 40). Common Repair Scenarios am4 pinout diagram
