Socket 4, presented in 1993, was the first CPU socket designed for the early P5 Pentium microprocessors. Socket 4 was the only 5-volt socket for the Pentium. Socket 4 does support a special Pentium OverDrive, which allows running at 120 MHz (for the 60 MHz Pentium) or 133 MHz (for the 66 MHz Pentium).{{Citation |title=Intel Socket 4 Specification |publisher=pcguide.com |url=http://www.pcguide.com/ref/cpu/char/socketSocket4-c.html |accessdate=2009-03-30}}
Socket 4 was superseded by the 3.3-volt-powered Socket 5 in 1994.
