4870x2 screen flickering

[TotalLamer]

Just got my new rig together... running what's in the sig. In any case, one of the first thing I tried to do was run Vantage, only to find that running it causes the screen to flicker gray. Later I installed WoW and tried to run it, same thing. I disabled Crossfire, so I'd only be running 1 4870x2... still did it. The only way to get rid of the screen flickering is to disable Catalyst A.I. which of course makes the card run on only 1 core. Any suggestions?

There is a problem with 4870 and Vista 64. Look for an updated BIOS from your video card manufacturer to fix the issue.

I've had my 4870X2 since release with Vista 64 and I've had no problems. No bios update needed.
