I have corsair ram and the only thing I have used icue for is to set the sticks to blue and then I have not touched it since. Icue does boot up at start time so not sure what your issue is. It will either work or drive you insane trying to get it to work.
RGD in PCs is a total s***show and the major players in this area should be utterly ashamed with themselves. They are across the board atrocious and everybody hates almost everything to do with RGB and the companies behind it.
