i need help enabling crossfire

i enabled it at ccc, and yet the info at the 3dmark06 says that its not linked. im getting around 5000 and i searched other with the same cards, they are at 8000+. some goes as high as 5 digits. im not overclocking anything except the processor. i keep seeing something called "hardware crossfire" and "software crossfire" but cant get more info about this.

any help please?

i tried different drivers like omegas, ngos, and warcat. im currently on the catalyst 7.1 from ati
