Brand: Intel · SKU: LGA1155-H2 · MPN: LGA1155 · Category: Components
The LGA 1155, also known as Socket H2, is a zero insertion force flip-chip land grid array (LGA) CPU socket designed by Intel for its desktop processors. It was introduced in January 2011 to support the 2nd Generation (Sandy Bridge) microarchitecture and later updated to support 3rd Generation (Ivy Bridge) processors. The socket features 1155 protruding pins that make contact with the pads on the bottom of the processor. It supports dual-channel DDR3 memory with data rates up to 1600 MHz and features the Direct Media Interface (DMI) 2.0 for high-speed communication between the CPU and the chipset. LGA 1155 motherboards typically use Intel 6-series (Cougar Point) or 7-series (Panther Point) chipsets. The mounting holes for heatsinks are spaced 75mm apart, maintaining compatibility with coolers designed for LGA 1156, 1150, 1151, and 1200 sockets.
