known as<\/span><b> Socket H2<\/b><span style=\"font-weight: 400;\">, is a CPU socket designed by Intel for <a href=\"https:\/\/bulkdevices.com\/cpus\">desktop CPUs<\/a> introduced in January 2011 with the Sandy Bridge processor family. The &#8220;1155&#8221; is the number of contact pins on the socket in the motherboard that match the number of contact pins on the bottom of the CPU.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is a socket for<\/span><b> DDR3 memory,<\/b><span style=\"font-weight: 400;\"> which usually runs at 1333 MHz or 1600 MHz, depending on the chipset and CPU. It also has a feature of supporting <\/span><b>PCIe 2.0<\/b><span style=\"font-weight: 400;\"> with Sandy Bridge boards, and once attached to an Ivy Bridge CPU with a compatible chipset, it will support <\/span><b>PCIe 3.0.<\/b><\/p>\n<p><span style=\"font-weight: 400;\">LGA 1155 is not the only widely used Intel socket, as it falls between two more widely used ones. Before it was <\/span><b>LGA 775,<\/b><span style=\"font-weight: 400;\"> which was designed to accommodate much older Core 2 Duo and Pentium 4 processors, and following it was the <\/span><b>LGA 1150,<\/b><span style=\"font-weight: 400;\"> designed for the Haswell generation, which arrived in 2013. All of these sockets are non-cross-compatible, so an LGA 775 CPU will not fit an LGA 1155 board.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n\n<table id=\"tablepress-17\" class=\"tablepress tablepress-id-17\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">Spec<\/th><th class=\"column-2\">Detail<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr class=\"row-2\">\n\t<td class=\"column-1\">Socket Name<\/td><td class=\"column-2\">LGA 1155 \/ Socket H2<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\">Launch Year<\/td><td class=\"column-2\">2011<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\">Pin Count<\/td><td class=\"column-2\">1,155<\/td>\n<\/tr>\n<tr class=\"row-5\">\n\t<td class=\"column-1\">Memory Support<\/td><td class=\"column-2\">DDR3<\/td>\n<\/tr>\n<tr class=\"row-6\">\n\t<td class=\"column-1\">PCIe Support<\/td><td class=\"column-2\">PCIe 2.0 (Sandy Bridge), PCIe 3.0 (Ivy Bridge)<\/td>\n<\/tr>\n<tr class=\"row-7\">\n\t<td class=\"column-1\">CPU Generations<\/td><td class=\"column-2\">Sandy Bridge, Ivy Bridge<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<!-- #tablepress-17 from cache -->\n<h2><span class=\"ez-toc-section\" id=\"Complete_LGA_1155_CPU_List\"><\/span><b>Complete LGA 1155 CPU List<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">This is an <\/span><b>LGA 1155 CPU list <\/b><span style=\"font-weight: 400;\">for all the mainstream Core, Pentium, Celeron, and Xeon processors of this socket, using product lines to help you locate your exact one.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Core_i7\"><\/span><b>Core i7<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The <\/span><b>Core i7<\/b><span style=\"font-weight: 400;\"> lineup is the strongest performer LGA 1155 has ever received.
