Thus, you can figure out that this socket was first launched in 2004. Socket LGA 775 had an extremely long-serving time that it serves for 7 years until the last CPU supporting it halted producing in 2011. Unlike its predecessor Socket 478 or other earlier common CPU sockets, instead of having socket holes, LGA 775 owns 775 protruding pins that can touch contact points on the bottom of the CPUs. Therefore, LGA 775 refers to a CPU socket that has 775 pins and a land grid array mounting surface. While “775” indicates the number of contacts (pins) the socket has. An LGA can be electrically connected to a PCB (printed circuit board, usually refers to computer motherboard) either by directly soldering to the board, or by using a socket, such as a CPU socket. It is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket if a socket is used, rather than the IC. It is also known as Socket T or socket 775.
LGA 775 is a kind of CPU socket for Intel desktops.
