One corner of the CPU features a 2x2 missing pin pattern (4 pins total), while the other three corners only have 3 missing pins. This mechanical keying ensures the chip can only be inserted in the correct orientation. Pin Types: The map includes hundreds of electrical pins for (core voltage), (ground), and dedicated lanes for DDR4 memory data PCIe signals Missing Pins:
