Demystifying the AM4 Pinout: A Guide for Ryzen Enthusiasts Frequently houses the I/O pins (PCIe and Memory)

These pins handle high-speed communication with your graphics card and NVMe SSDs. Most AM4 CPUs provide 24 PCIe lanes (16 for GPU, 4 for NVMe, and 4 for the chipset).

Advanced overclockers use pinouts to understand how voltage is supplied to the core versus the SOC. Key Sections of the AM4 Map
