The ASRock Z370 is an ATX motherboard with Intel's Z370 chipset for the 8th generation Intel processors (Coffee Lake) that use the LGA1151 socket as a foundation. The Z370 chipset is a refresh of the "kaby lake" chipset, which also has a maximum of 24 PCI Express 3.0 lanes and has enough HSIO lanes (high speed I / O) to provide multiple internal connections such as SATA or PCIe slots) at the same time. As a Z370 motherboard, the ASRock Z370 also allows the overclocking of K-series CPUs, which have a freely selectable multiplier.
