        If you want to see if your card should also use this controller, download the DLLs from the release of [this](https://gitlab.com/OpenRGBDevelopers/NvAPISpy).

        Perform the global replacement technique, which is specified in the README of NvAPI spy.  Once this is complete, use an RGB program of your choice and make some basic
        lighting changes.

        Check the C:\NvAPISpy\ folder and see if the logs created are filled with calls like this:

        If you see Get/Set Calls above for zone control, please create a [new device issue](https://gitlab.com/CalcProgrammer1/OpenRGB/-/issues/new?issuable_template=New%20Device#)
        and attach the relevant details to request support for your device (try various modes in each color, especially white and shades around it, since some cards treat RGBW as
        standard RGB).
