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
A significant portion of the 1331 pins is dedicated to power delivery. These pins ensure the CPU receives a stable voltage. Ground (VSS) pins are interspersed throughout the grid to reduce electrical noise and provide a return path for current.

The layout is designed to handle high power delivery, high-speed data for PCIe lanes, and memory communication. 1331 pins. Mounting Type: Zero Insertion Force (ZIF). Dimensions: mm (approximate outer housing). Memory Support: DDR4 (Dual-channel). Functional Zones of the Pinout
