Socket LGA 771 is a type of CPU socket used primarily for Intel's Xeon processors. Introduced in 2006, it features a land grid array design, allowing for better electrical connections and heat dissipation. This socket supports dual-processor configurations, making it suitable for servers and workstations that require high performance. The LGA 771 socket is compatible with several Intel processor families, including the Core 2 and Xeon 5100 series. It has 771 pins that connect the CPU to the motherboard, ensuring a secure fit. This socket was succeeded by LGA 775 and later by LGA 1366 for newer processor generations.
