Socket J, also known as LGA 771, is a CPU interface introduced by Intel in 2006. It is used in Intel's most recent DP-capable server processors, the Dual-Core Xeons codenamed "Dempsey" and "Woodcrest" and the Quad-Core Clovertown, as well as the new generation of Core 2 Extreme processors.
As its name implies, it is a land grid array with 771 contacts. The "J" in "Socket J" refers to the now-cancelled processor codenamed "Jayhawk", which was expected to debut alongside this interface. It is intended as a successor to Socket 604 and takes much of its design from LGA 775.
