I know what the problem is. I have the exact same problem on the exact same card. well i HAD the problem.
You need to overclock the 2D speeds:
Open AMD Vision Control Center (Advanced View).
Enter a profile name in the field.
Tick "Save" then close. Do not activate the profile yet. http://i403.photobucket.com/albums/p...14/clocks2.jpg
Now you will need to make sure you can view hidden folders on your system by going to the Control
Panel-->Folder Options-->View tab and select "Show hidden files, folders and drives." Close.
Go to your "My Documents" folder and open the AppData folder. From there open the Local folder->ATi->ACE then right click the Profiles document (Not the folder yet) and tick edit.
Highlight everything and tick Copy. Close.
Now open the Profiles folder then right click and tick edit on the profile (that you named earlier). Delete the entries in there, then paste in what you copied just earlier. http://i403.photobucket.com/albums/p...14/clocks3.jpg http://i403.photobucket.com/albums/p...14/clocks4.jpg
From there you change the two values below. As I indicate in the picture I'm using CrossFire so I have two entries to change. Input the 2D clocks you want, then Save.
Save it then right click the CCC icon and activate your profile
