Lights & Software on the ASRock Z790 LiveMixer Motherboard
As far as RGB lighting on the board all you have is a small strip of LEDs on the front-edge of the board. Part of this strip will likely be covered up by your graphics card, but will provide some nice under-glow inside of a case.
ASRock’s motherboard utility is called A-Tuning. Opening up on the first screen you can select a operation mode.
Next is the OC Tweaker tab where you can do all of your system tuning.
Next is System Info which gives you a live view of all of your frequencies, ratios, temperatures, and voltages.
Finally there is FAN-Tastic tuning which allows you to tune and set custom fan curves for each fan connected to your system.
