The ASRock Z390M Pro4 in detail
The ASRock Z390M Pro4 motherboard (MicroATX) provides a total of two PCIe x16 slots, one of which is connected to the chipset with full 16 lanes, while the others are connected with four or eight data lines. For additional plug-in and expansion cards, the motherboard has two PCIe x1 slots. In addition, multiple graphics cards can be used simultaneously on the motherboard and it supports AMD CrossFire and NVIDIA SLI.

The four DIMM slots support up to 64GB of DDR4 memory in dual-channel mode. Native support of the Z390 chipset clock rates up to 2.666 MHz, OC allows the ASRock Z390M Pro4 but also the operation of RAM kits up to 4.300 MHz. There are six SATA 6G connectors and two M.2 slots for hard drives and SSDs. Both M.2 slots are connected to the chipset with four PCIe lanes and support the NVMe protocol, which allows data transfer rates of almost 4 GB / s. This makes M.2 PCIe SSDs up to eight times faster than SATA 6G SSDs!

At the I / O panel, the ASRock Z390M Pro4 has a USB 3.1 connector with Type-C female connector. This new USB type C port is very thin and can be plugged in on both sides. USB 3.1 or USB 3.1 Gen 2 achieves maximum speeds of 10 Gbps per port, and USB ports with this standard generally support the fast charging function of smartphones and tablets. In addition to the I / O panel, there are four USB 3.0 ports as well as a D-Sub, HDMI and DisplayPort connection. Internally, the motherboard provides a large selection of ports and headers.

The special features of the ASRock Z390M Pro4 include, among other things, the numerous connections for fans - unusual for the compact form. A total of four 4-pin headers are distributed over the board, all of which can be controlled by automatic fan control. Two connections can also be used for water cooling pumps. Numerous temperature sensors ensure that the controller also works properly.
