I've got a message such as: Invalid reference clock from BIOS: 0.0 MHz –  litvin05 Nov 5 '10 at 18:55
    
Don't care about it. You can set the frequencies ignoring this message. This seems to be a common problem, and most people affected by it (including me) claim that it can be safely ignored and it works anyway. –  Rafał Cieślak Nov 7 '10 at 14:29

You can also try AMDOverdriveCtrl:
