LGA 1155, also called Socket H2, is a socket used for Intel microprocessors based on Sandy Bridge(2k) and Ivy Bridge(3k) microarchitectures. It was designed as a replacement for LGA 1156 (known as Socket H).

LGA 1155 has 1155 protruding pins to make contact with the pads on the processor. The pins are arranged in a 40×40 array with a 24×16 central void and additional 61 omitted pins (two adjoining the central void, six in each of the four corners, and 35 in groups around the perimeter), yielding the 1600 - 384 - 61 = 1155 pin count. Processors for LGA 1155 and LGA 1156 sockets are not compatible with each other since they have different socket notches. Cooling systems are compatible between LGA 1155 and LGA 1156 sockets, as the processors have the same dimensions, profile and construction, and similar levels of heat production. LGA1155 also marks the beginning with secure boot support in some later boards.

Original Sandy Bridge chipsets

Sandy Bridge chipsets, except Q65, Q67 and B65, support both Sandy Bridge and Ivy Bridge CPUs through a BIOS upgrade. Sandy Bridge based processors officially support up to DDR3-1333 memory, however in practice speeds up to DDR3-2133 have been tested to work successfully.

The H61 chipset only supports one double-sided DIMM Memory module (RAM module) per memory-channel and therefore is limited to 16 GB instead of the 32 GB like the others support. On H61-based motherboards with four DIMM slots, only four single-sided DIMMs can be installed.

Ivy Bridge chipsets

All Ivy Bridge chipsets and motherboards support both Sandy Bridge and Ivy Bridge CPUs. Ivy Bridge based processors will officially support up to DDR3-1600, up from DDR3-1333 of Sandy Bridge. Some consumer Ivy Bridge chipsets will also allow overclocking of K-series processors.
