Socket 604 is a 604-pin microprocessor socket designed to interface an Intel Xeon processor to the rest of the computer. It provides both an electrical interface as well as physical support. This socket is designed to support a heatsink.

Launched at November 18, 2002, over the year after Socket 603, it was originally used to accommodate most Xeons introduced at the time. It was succeeded by LGA 771 in 2006 for low- and mid-end server ranges, but still staying in high-end server range, including 4- and 8-processor configurations, in which the successor - LGA 1567 - appeared in 2010. At the time, LGA 1366 was the primary socket for Xeons in low- and mid-end server ranges, with cheaper configurations still sometimes using LGA 771 socket. The socket had an unusually long life span, lasting 9 years (2 years longer than consumer-grade LGA 775) until the last processors supporting it ceased production in the 3rd quarter of 2011.
