This is the most important step. AM4 CPUs have a small gold triangle printed on one corner of the processor's top surface. The same triangle also appears on the substrate's underside. The AM4 socket has a corresponding triangle marker embossed into the socket frame.
Unlatch the socket lever, pull the CPU straight out, and check the pinout pattern for any single pin that looks darker, slightly bent, or contaminated with thermal paste. Clean off thermal paste carefully using 99% Isopropyl alcohol and a soft-bristled static-free brush.

: Lift the small metal lever on the side of the AM4 socket to the vertical position. Align the Indicators : Locate the gold triangle on one corner of your Ryzen CPU. Match it with the triangle icon on the corner of the motherboard's CPU socket. Place the CPU
The computer turns on, fans spin, but the monitor receives no signal. This is the most important step
A pinout diagram is a visual representation of the pins on a CPU socket, showing their layout, function, and connection points. The AM4 pinout diagram, specifically, illustrates the 1331 pins on the AM4 socket, which is a significant increase from the 940 pins on the previous AM3+ socket. The additional pins on the AM4 socket enable support for features like DDR4 memory, USB 3.1 Gen 2, and SATA 6Gb/s.

Slide the edge of the card into the rows of pins on the underside of the CPU. Run the card down the entire row like a comb. The AM4 socket has a corresponding triangle marker
The lever must stand at a strict relative to the motherboard. This retracts the internal internal clamping plates inside the socket matrix. Step 3: Align the CPU Using the Alignment Markers
Locate the metal retention lever on the side of the plastic AM4 socket. Gently push it sideways to clear the plastic retention notch, then lift it all the way up until it is completely vertical (a 90-degree angle). Step 2: Match the Alignment Indicators
If the broken pin maps to a VSS ground pad, the CPU may still function perfectly because there are hundreds of redundant ground paths across the grid.
