I installed a 4890 Vapor-X by Sapphire. I had an extra PCI-e x16 slot so I threw in my 9800GT for Quadruple-Monitor. For some reason, my 4890 Won't initialize at all. My 9800GT Starts up fine. I tried swapping the 4890 and the 9800GT's slots to no avail. As far as the computer can tell, the 4890 doesn't even exist. When I take out the 9800GT the 4890 works like normal. When I start up Catalyst, it gives me an error telling me that I have wrong drivers. I have both the 4890vapor-x drivers and the 9800GT's drivers installed. I read some place that if the video card has a boot-up/bios screen, it will initialize last or not at all. I updated my bios to the latest and I got no options to initialize the 4890 first. Is it possible to use these 2 together? (NOT Intended for sli/X-fire). I will be fine taking out the 9800GT and putting it to some better use. EDIT: Vista on SLi board.
