Radeon 6850 crossfire

yes, you can crossfire it, but remember the faster card will automatically match itself to the slower card.

Thanks for information.
Maybe i should replace DirectCU with IceQ X turbo.

it's ok good to go..

No it'll be fine, just make the clock speeds are the same.

My Asus DirectCU 6850 is running at 850/4400 on stock voltages and has never shown the slightest blip. Set them both to the speed of the HIS IceQ and you'll be fine.
