Socket 5

Socket 5 was created for the second generation of Intel P5 Pentium processors operating at speeds from 75 to 133 MHz^[1][2] as well as some Pentium OverDrive and early Pentium MMX processors with core voltage 3.3 V. Released in March 1994, it superseded the earlier Socket 4.^[3] Consisting of 320 pins, this was the first socket to use a staggered pin grid array (SPGA), which allowed the chip's pins to be spaced closer together than earlier sockets. Socket 5 was replaced by Socket 7 in 1995.^[4]
