crossfire unchecks itself after i hit apply?

[pnico]

hi guys,

I just got 2 radeons in crossfire, two 5970's and want to crossfire them together.

I'm running 10.2. I get the option to crossfire but after i hit apply, it unchecks itself..

any ideas?

Did you uninstall the drivers for the single 5970 before installing the 2nd 5970? You do have the CF bridges installed on the cards right?..
