Bearing in mind that Radius' claim is that the Rocket cards run as a Quadra 950 within the host Mac, whichever model that may be, you may be suffering from the effect mentioned here, ie, that your video card is not Quadra-compatible.
It was my intention to put both of my Rocket cards into a Quadra 950 when the time comes, which may have been a serendipitous outcome of my first reason: that the Q 950 PSU is capable of supplying 300W, which is no bad thing to have in reserve in the light of the trouble that a single Rocket card can cause to the likes of the IIcx, or even to NuBus slot E (nearest to the PSU) in a IIci.
