These pins deliver power to the CPU cores. If one of these is missing, you might still boot, but stability under load will suffer. VSS (Ground): am4 pinout diagram exclusive

Certain pins alter their behaviour based on the processor installed. Install a standard Ryzen CPU, and the display pins sit dark while the full PCIe lane allotment runs to the expansion slots. Swap it for an APU, and those pins instantly reroute to drive video display streams. 5. Diagnostics and Pin Repair Realities
