Socket 604 is a 604-pinmicroprocessor socket designed to interface anIntelXeon 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 afterSocket 603, it was originally used to accommodate most Xeons introduced at the time. It was succeeded byLGA 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-gradeLGA 775) until the last processors supporting it ceased production in the 3rd quarter of 2011.
Socket 604 was designed by Intel as azero insertion force socket intended for workstations and server platforms. While the socket contains 604 pins, it only has 603 electrical contacts, the last being a dummy pin.[1] Each contact has a 1.27mm pitch with regular pin array, to mate with a 604-pin processor package.
Socket 604 processors utilize a bus speed of either 400, 533, 667, 800, or 1066 MHz and were manufactured in either a 130, 90, 65 or 45 nm process. Socket 604 processors cannot be inserted intoSocket 603 designed motherboards due to one additional pin being present, but Socket 603 processors can be inserted into Socket 604 designed motherboards, since the extra pin slot does not do anything for a 603 CPU.
Socket 604 processors range from 1.60 GHz through 3.80 GHz, with the higher clock rates only found among older, slowerNetBurst-based Xeons.
