Am4 Pin: Layout

Dedicated pins for USB 3.1, SATA connectivity, and Display Output. USB_SS , SATA_ZVDDP , DP_TX

Because the pins are on the CPU, alignment is critical to prevent bending.

Heatsink mounting holes are arranged in a 54mm x 90mm rectangle. Pin Mapping and Functional Groups am4 pin layout

OPGA (micro Pin Grid Array) configuration served as the foundation for the Ryzen revolution from 2017 through the early 2020s.

The 1,331 pins are not identical; they are divided into functional blocks that manage power, data, and system signals. Functional Group Description Key Pin Labels

Supports up to 24 PCIe lanes (PCIe 3.0/4.0 depending on the CPU generation).
