Socket LGA 1151 Z170 board
The ASRock Z170 Gaming K4 is an ATX motherboard built around the Intel Z170 chipset for LGA 1151 processors. It accepts Core i7, i5, i3, Pentium and Celeron CPUs with Turbo Boost 2.0 support. Four DDR4 slots take up to 64 GB of memory running at 2133 MHz standard with overclocked profiles up to 3866 MHz. The board provides two PCI Express 3.0 x16 slots and three x1 slots for expansion cards.
Upgrade from older chipsets
Moving to Z170 brings DDR4 support and native SATA 6 Gb/s across six ports plus two SATA Express 10 Gb/s connectors. The single Ultra M.2 slot adds high-speed storage potential, though populating it with a SATA-type M.2 device disables SATA3_0 and the SATA function of SATA3_2_3 and SATA3_4_5. RAID 0, 1, 5 and 10 are available on the SATA array. Killer E2400 networking and Realtek ALC1150 7.1 audio replace older integrated controllers.
Gaming and enthusiast builds
This board suits builders who want Z170 overclocking features, multi-GPU capability via two x16 slots and a full set of SATA ports for mixed storage. Users needing multiple M.2 drives, integrated Wi-Fi or a smaller form factor should consider other models. The ATX layout requires a compatible case and standard power connections.

Questions about this item
What case clearance does the ATX form factor of the Z170 Gaming K4 require?
The board follows the standard ATX layout, so it fits any case that accepts ATX motherboards and provides the usual I/O shield cut-out and mounting-hole pattern.
Which step is most often missed when seating the CPU in the LGA 1151 socket?
Align the notches on the processor with the socket keys, lower it gently without pressure, then close the retention lever fully until it clicks under the tab.
What is the maximum DDR4 capacity the four 288-pin slots can hold?
The board supports up to 64 GB of DDR4 memory across its four slots.
