So I have a really weird issue.
I'm running dual 2048MB ATI AMD Radeon HD 7800 Series, using Crossfire.
I've got the bridge over the cards, and I've enabled crossfire in CCC.. kind of.

When I open CCC, and press the AMD CrossFireX tab, the
"Enable AMD CrossFireX" option is already checked .

Well, that makes you think I've got it enabled, right? Well...
There's a message over the options saying "Choose to enable AMD CrossFireX for added graphics performance", now this makes me think it's disabled, but I cannot enable or discard it..

Also, I've been using Piriform Speccy to check what kind of hardware my computer's got, and how hot the different componments are, and Speccy tells me that CrossFire is Disabled.

You probably did not understand anything from what I just said, I've tried writing it several times explaining it differently but I just don't know how. (English is not my first language.)

Here's a screenshot of CCC when I'm in the CrossFireX tab: http://i.imgur.com/XXrKjbf.png

Thanks for all help, I'd be grateful!
 
Solution
your second pcie slot mustt operate to at least x4 mode. some mobos may have it by default at x2 mode. go into bios and change it. another thing you should mind is that on some mobos when on xfire you cant have occupied any other pcie slot even if it is x1 mode.
