Proper alignment is critical to avoid bending pins. Every AM4 CPU and socket has visual indicators:
AMD’s AM4 socket, also known as , features a PGA (Pin Grid Array) layout. Unlike Intel’s LGA (Land Grid Array) where pins are on the motherboard, AM4 places 1,331 pins directly on the underside of the processor. These pins fit into a Zero Insertion Force (ZIF) socket on the motherboard, measuring approximately 40mm x 40mm . Functional Pin Categorization am4 pin layout
– twist the cooler gently to break thermal paste adhesion, or the CPU will come out stuck to the heatsink, bending hundreds of pins. Proper alignment is critical to avoid bending pins
These are redundant grounding pins scattered throughout the layout [8]. If a single VSS pin breaks, the CPU may still function normally, though it is not recommended to rely on this [8, 10]. These pins fit into a Zero Insertion Force
