The first tab is the “Main” Tab and only includes system information and a list of settings that have been flagged by the user as “Favorite”. The Advanced BIOS mode brings out all of the motherboard’s options and features, cleanly organized under seven major tabs. Assuming that the user escaped blindness, the thermal profile of the cooling fans connected to the motherboard’s headers can be either selected from four pre-programmed presets or manually programmed.

Finally, the “FAN-Tastic” tuning tool brings up a bright red screen that will try and burn the user’s retinas. The tool will display information on the device that is attached/connected on the port or slot that the pointer is placed on. The “System Browser” tool is identical to MSI’s “Board Explorer” it brings up an image of the motherboard and its rear I/O panel, where the user can “explore” the board with the mouse’s pointer.

There is the “Instant Flash” option that allows the user to flash a BIOS available into a USB drive, but there is also an “Internet Flash” option that has the ASRock Z270 Killer SLI automatically connecting to the company’s servers, checking, downloading and flashing the latest stable BIOS instantly, without having to download it from inside an OS. The “Tools” Tab does bring up some interesting functions though. From this mode only basic features and functions are accessible, with most tabs being purely informative in function. The BIOS defaults to a simple, single page mode, called the “EZ Mode”. The ASRock Z270 Killer SLI features a graphical UEFI BIOS, much like every modern motherboard these days.
