Socket 423
Updated: 08/02/2020 by Computer Hope
The Socket 423, utilizing the pin grid array, was used by Intel for the Pentium 4 processor, but only for a short period. It was used from November 2000 to August 2001, less than one year, for Pentium 4 1.3 GHz to 2.0 GHz processors. It was determined to be inadequate for use on processors over 2.0 GHz in speed and was discontinued.
Socket 423 Pentium 4 processors had a voltage range of 1.0 to 1.85 and a physical size of 2.1-inches by 2.1-inches. When discontinued in August 2001, it was replaced by Socket 478 processors. Due to the short life of Socket 423, an adapter was built, called the PowerLeap PL-P4/N, that allowed for Socket 478 processors to be used in a Socket 423 motherboard.
