If you do not restrict the clock on the Brooktree Bt485 RAMDACS, then you are risking HARDWARE damage to your video card. At ~$300/card, I would not want to be using XS3 when my card went belly-up. Note that the limitation is for a particular RAMDAC, and not for all RAMDACS. A fix is in the works, but the release needed to go out the door.
