If you flip a Ryzen CPU over, you will see a sea of gold pins, but three distinct “void” zones where no pins exist. These are not manufacturing defects; they are mechanical keys and also allow room for surface-mounted capacitors on the CPU substrate.
Due to PGA nature, AM4 CPUs are vulnerable to bent pins. Critical pins: am4 pin layout
– The foam used in some generic trays can snag pins. If you flip a Ryzen CPU over, you
Complete 1331-pin maps are maintained by the community at resources like "AM4 V1.6 Pinout" (IOShield). am4 pin layout
Pin mapping for DDR4 is fixed, but memory topology (T-topology vs. daisy-chain) is motherboard-dependent.
