Here are some of the first pictures of ASRock Z270 Extreme4, the company's mid-range socket LGA1151 motherboard based on Intel's upcoming Z270 Express chipset, with out of the box support for 7th generation Core "Kaby Lake" processors, and support for Intel Optane 3D X-point solid-state storage. Built in the ATX form-factor, the Z270 Extreme4 draws power from a combination of 24-pin ATX and 8-pin EPS connectors, and conditions it for the CPU with a 12-phase VRM.

The CPU socket is wired to four DDR4 DIMM slots, supporting up to 64 GB of dual-channel DDR4 memory; and two PCI-Express 3.0 x16 slots (electrical x8/x8 when both are populated). The third PCIe 3.0 x16 slot is electrical x4 and wired to the PCH. Three open-ended PCIe 3.0 x1 slots make for the rest of the expansion area. Storage connectivity includes eight SATA 6 Gb/s ports, and two 32 Gb/s M.2 slots. Display connectivity includes one each of D-Sub, DVI, and HDMI. You get a total of eight USB 3.0 ports (four on the rear panel four by headers), and two USB 3.1 ports (one each of type-A and type-C, both on the rear panel). Eight channel HD audio and gigabit Ethernet make for the rest of the connectivity.

Early 2017, a new wave of socket LGA1151 motherboards based on Intel 200-series chipset will launch, alongside the company's 7th generation Core "Kaby Lake" processors. The lineup will be led by the Z270 Express, targeting performance desktops, and H270 Express, targeting premium commercial desktops. The question on your mind probably is what sets these chipsets apart from the current 100-series Z170 and H170 chipsets. Here are some pointers.

To begin with, motherboards based on Z270 and H270 chipsets are assured to support Core "Kaby Lake" processors, out of the box. The 100-series chipset motherboards inventory with retailers may require BIOS updates, although some of the newer production batches could ship with the latest BIOS that support "Kaby Lake." Secondly, the Z270 and H270 support Intel Optane technology, a new breed of bleeding-edge performance SSDs based on the company's 3D X-point non-volatile memory, which is the very latest in sold-state storage, and purported to be the fastest. The chipets also support Rapid Storage Technology v15.
