1. You can compare the score with/without Crossfire.

 

2. If you have other monitors, use GPU-Z to see the activity of the second GPU.

In performance tab of CCC it should say that it is.

Right mouse click CCC icon in Tasktray. Look at the first video card and under Crossfirex settings click show crossfirex status icon (where applicable).

Generally then when Crossfire is being used it will show a transparent logo, top right corner of the app that is utilising it.

Just remember though a game has to be in fullscreen mode to utilize crossfire. If you are in windowed or windowed fullscreen then it will only use one card not both.

Use only one bridge. Two bridges will not add any bandwidth or performance, more like will cause cross talks resultin graphical glitches.

Try this:

 

  • Uninstall all tweaking applications such as Afternurner, Trixx etc if you have it in the system.
 
  • Uninstall Catalyst package & CAP. Select "Express Uninstall"
 
  • Delete these folder;
  • C:\user\Program files or (x86)\ ATI or AMD
  • C:\user\ProgramData\ATI or AMD
 
  • Clean it with;
    (Run with administrator privilege. Some antivirus software will give a false positive. Let it restarts to complete the uninstallation - Disable UAC to install this cleaner).
