I'm having some weird issued with my Crossfire setup. It was working just fine for the last month or two but lately it hasn't been working at all. One card would render things just fine but anytime I'd open a 3D app with Crossfire enabled the screen would just black out.
I finally reinstalled WinXP and just used the ATI 6.9 drivers (I was using the Warcat 6.6 + Chuck before). I can now get 3D apps to open and run but everything is capped at 40fps and I get a flashing screen sometimes, like in Firefly in 3DMark05. Here is what I've tried up to this point:
Using .NET 1.1 & 2.0 (fully updated)
Uninstalled X-Fi card through Device Manager
Uninstalled McAfee Virus Scan (heard there may be probs with CLI.exe and McAfee)
All CCC settings are at default except for Crossfire being enabled (V-Sync is off)
Physical inspection of both cards to ensure that no water dripped on them
Tried older chipset drivers that came on MSI CD
Not sure what went haywire but I'm only hitting 9,691 in 3DMark05 now which is less than a single card. Any ideas??
