Was thinking about buying another 5770 for my 5,1 Mac pro. I wanted to run it in crossfire mode under windows. Just wanted to see if anyone here is running the same setup and how their experience has been. I know I would also need a crossfire bridge. Thanks for the help.

I have a MP 5,1 with dual HD 5770s.

I running Win Pro 64 in bootcamp. I have the CrossFire Bridge installed. I'm running AMD Catalyst 10.11 (64Bit). This will enable both of your cards under windows. I've tried the newer versions of Catalyst and when clicking on Enable Crossfire, I would get the Blue Screen of Death. This would be with or with the Bridge installed. The Bridge will not fit without filing down one of the little tabs that stick out.


I play Call of Duty, BF3, Medal of Honor, Crysis2, and HomeFront without any issues.

Interesting. Thank you for the input. Does the expansion fan rev at all when the cards are under load?

Have you been able to get crossfire working with any other drivers other than 10.11? I am trying with two 7970's and I get a BSOD on enabling crossfire every time. In both windows 7 AND windows 8 using drivers 12.10 on up.
