'''Socket 423''' is a 423-pin [[CPU socket]] used by [[Intel]]'s first generation of [[Pentium 4]] [[Central processing unit|processors]] based on the [[Pentium 4#Willamette|Willamette]] core.
This socket was short-lived, as it became apparent that its electrical design proved inadequate for raising [[clock speed]]s beyond 2.0&nbsp;GHz. Intel produced chips using this socket for less than a year, from November 2000 to August 2001.
Socket 423 was replaced by [[Socket 478]] in 2001. Socket 478, being microPGA, was cheaper to manufacture than Socket 423.<ref>{{Cite web|url=https://www.anandtech.com/show/778/2|title=Computex 2001 Day 1 - Live Coverage}}</ref>
==Technical specifications==
Socket 423 was designed to house any processor in the Socket 423 package.
All processors using this socket have a locked multiplier, meaning that they are not overclockable unless the [[front side bus]] frequency is increased. Doing this, however could push other buses out of spec, causing erratic behaviors such as system instability and premature failure.
The "PowerLeap PL-P4/N" is a device developed in the form of a socket adapter that allows the use of Socket 478 processors in Socket 423 motherboards.
