Original Sandy Bridge chipsets[edit]

Sandy Bridge chipsets, except Q65, Q67 and B65, support both Sandy Bridge and Ivy Bridge CPUs through a BIOS upgrade.^[3] 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.^[4]
The H61 chipset only supports one double-sided DIMM per memory-channel and therefore is limited to 16 GB instead of the 32 GB like the others support.^[5] On motherboards with four DIMM slots, only four single-sided DIMMs can be installed.^[6]

¹ USB 3.0 is not supported by any of these chipsets. Motherboard manufacturers may use external hardware to add USB 3.0 support.
² Although some of the chipsets do not support conventional PCI, motherboard manufacturers may include support through the addition of third party chips.

Ivy Bridge chipsets[edit]

Socket 1155, also called LGA1155, or socket H2, is a Land Grid Array socket that superseded socket 1156. The LGA1155 was introduced in January 2011 along with second-generation Core CPUs, built on Sandy Bridge microarchitecture. The socket 1155 (H2) was also utilized for Ivy Bridge microprocessors, that were launched in 2012. The LGA1155 works with the latest generations of Intel Celeron, Pentium, Core i3/i5/i7 and Xeon desktop and server processors, that have up to 4 CPU cores, up to 8 MB of L3 cache, and operate at frequencies ranging from 1.2 GHz to 3.7 GHz. The socket H2 supports dual-channel DDR3 memory with data rates up to 1600 MHz, Direct Media Interface 2.0 running at 5 GT/s, and PCI Express 2.0 and 3.0 interfaces. Reportedly, the LGA1155 will be replaced with socket 1150 in 2013.

The size of the socket without Independent Loading Mechanism (ILM) is 1.67" x 1.67" (4.25 cm x 4.25 cm). The socket H2 has 1155 contacts arranged as a grid 40 x 40 contacts with 24 x 16 section de-populated in the center, and with 61 land contacts depopulated mostly from the socket corners and socket edges. Visually, the contacts look like two L-shaped sections, opposing each other. The socket 1155 is rated at minimum 20 processor insertion and removal
