'''Socket 1''', originally called the "OverDrive" socket, was the second of a series of standard [[CPU socket]]s created by [[Intel]] into which various [[x86]] [[microprocessor]]s were inserted. It was an upgrade to Intel's first standard 169-pin [[pin grid array]] (PGA) socket and the first with an official designation. Socket 1 was intended as a 486 upgrade socket, and added one extra pin to prevent upgrade chips from being inserted incorrectly.

Socket 1 was a 169-pin [[zero insertion force]] (ZIF) 17×17 [[pin grid array]] (PGA) socket suitable for the 5-[[volt]], 16 to 33 [[MHz]] [[486 SX]], [[486 DX]], [[486 DX2]] and [[486 OverDrive]] processors.<ref>{{Citation |title=Intel Socket 1 Specification |publisher=pcguide.com |url=http://www.pcguide.com/ref/cpu/char/socketSocket1-c.html |accessdate=2008-03-30 |url-status=dead |archive-date=2008-03-20 |archive-url=https://web.archive.org/web/20080320071309/http://www.pcguide.com/ref/cpu/char/socketSocket1-c.html }}</ref> One source claims that it was also used for the [[i487SX]] upgrade socket.<ref name=informit>{{cite web | last= | first= | date=June 8, 2001 | url=https://www.informit.com/articles/article.aspx?p=130978&seqNum=28 | title=Microprocessor Types and Specifications | work=InformIT | publisher=Pearson | archiveurl=https://web.archive.org/web/20211207005251/https://www.informit.com/articles/article.aspx?p=130978&seqNum=28 | archivedate=December 7, 2021}}</ref>
