HD 7770 Crossfire Help

[AgeOfEpicness]

Hi, I just purchased a second Asus HD 7770 and i would like to crossfire them. I'm not sure how to go about this as in what I need to enable. On the motherboard I need to put them in the same color slots, correct?
I have a Sabertooth 990fx with Windows 7 Professional 64 bit.

Yes, the 2 light colored slots will give the best performance. This is where is is handy to open your manual and have a peek. ;-) Be sure to use the XF bridge. Re-boot and CCC should recognize there is a 2nd card. You may have to go into CCC and enable CF manually though. (Don't be surprised if micro-stutter rears its ugly head in some games with those two mid range cards, though)

How do i enable crossfire in CCC?

I don't have a CF system to look at right now, but as I remember it is under "Gaming/3D Application Settings".
