Ati 5850 crossfired.. ccc issues

[Novadreams]

Hi,
So after much research (I had my ATI 5850's) crossfired w/a dual monitor and there was flickering. The problem was solved by turning off ccc overdrive. I'm nothing close to a pro but what does 'overdrive' do exactly and has ATI acknowledged these issues yet? Additionally will I get a screen flicker if I was to manually set the ccc controls for my cards to high settings?

Your cards must had been unstable during overclocking. Get Msi after burner, and tweek with your clock settings.

But if I never oc'd them...? I'll download msi and goof around with some se ttings but not too sure how that coulda occurred.

I think this is a known issue. If I remember right, it has something to do with the cards using the wrong BIOS setting at idle.
