For the Palit GameRock, which is installed in this system, you can use ThunderMaster, for example. This is the Palit software for all settings of the graphics card, including LED lighting.
depends on which manufacturer is installed....if it is an asus, then the same software as the mainboard armoury crate aura sync...if it is a msi then via msi mystic light...if it is a gigabyte then gigabyte rgb fudsion 2.0.....the best thing is to go to the manufacturer page of the graphics card and download the rgb software
