LGA 1151 is designed as a replacement for the LGA 1150 (known as Socket H3). LGA 1151 has 1151 protruding pins to make contact with the pads on the processor. The Fully Integrated Voltage Regulator, i.e. a voltage regulator which integrated on the CPU's die, introduced with Haswell and Broadwell, has again been moved to the motherboard.
Most motherboards for the first revision of the socket support solely DDR4 memory, a lesser number support DDR3(L) memory,{{Cite web |title=GIGABYTE - Motherboard - Socket 1151 - GA-Z170-HD3 DDR3 (rev. 1.0) |url=https://www.gigabyte.com/products/product-page.aspx?pid=5488 |website=Gigabyte |language=en-US |access-date=September 7, 2015}} and the least number have slots for both DDR4 or DDR3(L) but only one memory type can be installed.{{Cite web |title=ASRock > B150M Combo-G |url=https://www.asrock.com/mb/Intel/B150M%20Combo-G/ |website=ASRock |language=en-US |access-date=September 15, 2015}} Some have UniDIMM support, enabling either type of memory to be placed in the same DIMM, rather than having separate DDR3 and DDR4 DIMMs.{{Cite web |last=Cutress |first=Ian |date=August 5, 2015 |title=The Intel 6th Gen Skylake Review: Core i7-6700K and i5-6600K Tested |url=https://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/2 |website=AnandTech |language=en-US |access-date=August 5, 2015}} The second revision socket motherboards support only DDR4 memory.
Skylake, Kaby Lake, and Coffee Lake chipsets support VT-d, Intel Rapid Storage Technology, Intel Clear Video Technology, and Intel Wireless Display Technology (an appropriate CPU is required). Most motherboards with the LGA 1151 socket support varying video outputs (DVI, HDMI 1.4 or DisplayPort 1.2 – depending on the model). VGA output is optional since Intel dropped support for this video interface starting with Skylake.{{Cite web |title=Intel® Core™ i7-6700K Processor (8M Cache, up to 4.20 GHz) |url=https://ark.intel.com/products/88195/ |website=intel |language=en-US |access-date=August 6, 2015}} HDMI 2.0 (4K@60 Hz) is only supported on motherboards equipped with Intel's Alpine Ridge Thunderbolt controller.{{Cite web |last=Cutress |first=Ian |date=August 5, 2015 |title=Intel Skylake Z170 Motherboards: A Quick Look at 55+ New Products |url=https://www.anandtech.com/show/9485/intel-skylake-z170-motherboards-asrock-asus-gigabyte-msi-ecs-evga-supermicro |website=AnandTech |language=en-US |access-date=August 6, 2015}}
Skylake, Kaby Lake, and Coffee Lake chipsets do not support the legacy conventional PCI interface; however, motherboard vendors may implement it using external chips.

There is no equivalent Kaby Lake chipset analogous to the H110 chipset. Four additional PCH PCI-E lanes in Kaby Lake chipsets are reserved for implementing an M.2 slot to support Intel Optane Memory.

LGA 1151 revision 2
The LGA 1151 socket was revised for the Coffee Lake generation CPUs and comes along with the Intel 300-series chipsets.{{Cite news |last=Cutress |first=Ian |date=October 5, 2017 |title=The AnandTech Coffee Lake Review: Initial Numbers on the Core i7-8700K and Core i5-8400 |url=https://www.anandtech.com/show/11859/the-anandtech-coffee-lake-review-8700k-and-8400-initial-numbers/3 |website=AnandTech |language=en-US |access-date=October 5, 2017}} While physical dimensions remain unchanged, the updated socket reassigns some reserved pins, adding power and ground lines to support the requirements of 6-core and 8-core CPUs. The new socket also relocates the processor detection pin, breaking compatibility with earlier processors and motherboards. As a result, desktop Coffee Lake CPUs are officially not compatible with the 100 (original Skylake) and 200 (Kaby Lake) series chipsets.{{Cite news |last=Cutress |first=Ian |date=August 21, 2017 |title=Intel Launches 8th Generation Core CPUs, Starting with Kaby Lake Refresh for 15W Mobile |url=https://www.anandtech.com/show/11738/intel-launches-8th-generation-cpus-starting-with-kaby-lake-refresh-for-15w-mobile |website=AnandTech |language=en-US |access-date=August 22, 2017}} Similarly, 300 series chipsets officially only support Coffee Lake and are not compatible with Skylake and Kaby Lake CPUs.
Socket 1151 rev 2 is sometimes also referred to as "1151-2".

Like with Kaby Lake chipsets, four additional PCH PCI-E lanes in Coffee Lake chipsets are reserved for implementing an M.2 slot to support Intel Optane Memory.
There's a 22 nm version of H310 chipset, H310C, which is sold only in China.{{Cite web |last=Tyson |first=Mark |date=September 20, 2018 |title=Intel tech roll back: it is fabbing the new H310C chipset at 22nm |url=https://hexus.net/tech/news/mainboard/122372-intel-tech-roll-back-fabbing-new-h310c-chipset-22nm/ |website=Hexus |language=en-GB |access-date=January 13, 2019}} Motherboards based on this chipset support DDR3 memory as well.
