The 1,331 pins are categorized into specialized functional groups that allow the CPU to communicate with the rest of the system: | Feature | AM4 (PGA) | AM5 (LGA)

Imagine looking at the bottom of an AM4 CPU with the gold triangle indicator at the . The pin field is a near-square matrix, but large chunks are removed from all four corners. The missing pin pattern is asymmetrical: the bottom-left corner has a large triangular cutout, while the top-right corner has a smaller rectangular cutout. The pin field is a near-square matrix, but

Because the pins flex under the CPU weight, you must tighten a cooler on one corner fully before the others. Always tighten in an "X" pattern gradually (2 turns per screw). Uneven pressure can literally rip the copper pads off the bottom of the CPU or bend pins under the socket's spring tension.
