At the low-end of the 100 series spectrum is the other H series chipset, the H110, which is further stripped down from the Z170. It lacks support for RST, Smart Response Technology, Smart Sound Technology, Small Business Advantage 4.0, RAID, overclocking, and multi-GPU configurations. It also loses more than half the USB 3.0 support of the Z170 chipset. The number of HSIO lanes available falls sharply, and their use is limited. Memory support is reduced as well, as only a single DIMM is permitted in each channel. Finally, the H110 is also the only chipset to lack PCI-E 3.0 support; instead it uses eight lanes of the older PCI-E 2.0 standard.
The H110 chipset doesn't offer much, but it still supports the Skylake CPU, DDR4 and a PCI-E 3.0 connection for a GPU. The H110 chipset will likely be used on the cheapest LGA 1151 motherboards, however, which will make it easier for consumers to upgrade to Skylake without needing to pay out quite as much.
