ASRock does have their own graphics card companion software called OC Tweak. Opening it up you have the ability to see your cards clocks, temperature, and fan speeds in real time. You can also set the card to its default, OC mode, silent mode, or a user defined mode.
RGB lighting controls for the card are in ASRock’s Polychrome Sync software, which is a completely different application. It is pretty easy to use, you can select the two different lighting zones of the card or control them individually.
Talking about RGB lighting you have RGB lighting in the center fan as well as on the top edge of the card. For a lower-end card like the RX 6600 XT it is pretty nice to see this much RGB lighting. ASRock was actually one of the first to add RGB lighting to their GPU fans. In our test bench this looks excellent, but in a normal system the fan will be facing down, unless you go for a vertical GPU setup.
