Board Layout

The ASRock Fatal1ty X370 GAMIGN K4 comes with the now-standard Fatal1ty looks; all black and red. While the GAMING K4 is still an entry-level board, the board seems svelte and optimized, with a well-organized layout.


The socket area is very nice, with very few components to get in the way of installing a large heatsink to keep your Ryzen CPU's temperatures in check. The four DIMM slots support up to 2933 MHz memory only, at least officially.


Expansion capabilities include dual PCIe x16 slots and four PCIe x1 slots. With both PCIe x16 slots populated with dual-slot VGAs, you'll still have three of those PCIe x1 slots accessible, and only one of the PCIe x1 slots gets covered. The rear I/O panel is a mad mix of USB ports of various types, a LAN port, single HDMI port, and the standard grouping of five analogue audio ports and an optical output. There are provisions here for Wi-Fi antennas, but the Wi-Fi card itself is not included in the box. The strange bits here are the dual PS/2 ports; one for your mouse and another for your keyboard. This is an interesting choice, for sure, as I'm not sure how many PS/2 mice are still on the market these days. Someone must have asked ASRock for this.


SATA connectivity provides the Fatal1ty X370 GAMING K4 with just six SATA 6 Gb/s ports.


There are dual M.2 ports here; the top one is PCIe 3.0 x4 and SATA 6 Gb/s capable, and the lower port is PCIe 2.0 x2 capable (so quite a bit slower for PCIe devices), but still ready for SATA 6 Gb/s devices.


The board's bottom edge is filled with a rather standard array of pin headers, but what stands out here are the provisions for dual 5050 RGB LED strips.


LAN duties are managed by an GigaLAN Intel I211AT controller and can be expanded to include Wi-Fi by using the provided M.2 (Key E) slot.
