Am4 Pin Layout <1080p>

The AM4 socket uses a square physical package measuring roughly . Unlike Intel’s LGA (Land Grid Array) sockets, which place pins on the motherboard, AM4 follows a PGA (Pin Grid Array) design where the pins are located on the underside of the processor. Key Specifications Pin Count: 1,331 pins in a 1.14mm pitch grid. Memory Architecture: Dual-channel DDR4.

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 am4 pin layout

OPGA (micro Pin Grid Array) configuration served as the foundation for the Ryzen revolution from 2017 through the early 2020s. The AM4 socket uses a square physical package

Because the pins are on the CPU, alignment is critical to prevent bending. Memory Architecture: Dual-channel DDR4

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

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

Large clusters of pins that provide high-current voltage to the CPU cores and SoC. VDDCR_CPU , VDDCR_SOC , VSS (Ground)
