Hey everyone.
Was wondering if there is something you can suggest i try or a possible explanation. I recently picked up 2 Visiontek Radeon HD 4870's and am trying to run them in crossfire.
I got them installed fine on a MSI P35 Neo2 motherboard, everything booted great, had no troubles with the included 8.6 catalyst drivers. Detected both cards, enabled crossfire, thought everything was great. Any game i ran had horrible horrible performance, unplayable at the same settings that the single card ran fine. A lot of screen flickering and font scaling problems. I tried hellgate london, WoW, Age of Conan, Quake Wars, and UT 3. Absolutely atrocious the way they ran.
So fine, i thought i'd upgrade to 8.7. As i was installing, it said there was a problem with the second card and its being disabled, and no matter what i do it won't start the second card. In the device manager it says "Windows has stopped this device cause it has reported problems. (Code 43)"
Perhaps this is a defective card? but i don't know why it would say everything is fine under 8.6 (besides the horrible performance.)
Not sure what info you need from me, but i am running Vista Ultimate 64 with a Quad Core Q6600 and 8GB of RAM.
Any direction would be appreciated.
