Technical specificationsEdit
Socket 8 is a unique rectangular CPGA socket with 387 pins. It supports FSB speeds ranging from 60 to 66 MHz, a voltage from 3.1 or 3.3V, and support for the Pentium Pro and the Pentium II OverDrive CPUs. Socket 8 also has a unique pin arrangement pattern. One part of the socket has pins in a PGA grid, while the other part uses a SPGA grid.[1]
Intel did not return to rectangular sockets until the launch of LGA 1700 in late 2021.
