Crossfire issues in 12.8

post #1 of 4
Thread Starter 
Bought a XFX 6870 1GB about four months ago and just got a screaming deal on an Asus 7870 2GB. So I wanted to crossfire them even though I know that the 7870 will be down clocked to match the 6870. Two 6870's is better than one smile.gif

Anyways, I have everything plugged in correctly with the bridge in place but no where in AMD 12.8 does it give me the option to check or un-check crossfire. I have drivers for both cards in place, with the monitor HDMI cable hooked into the 7870. No visual issues to note so far. I just know there not actually synced yet and I cant get them to crossfire. I also cannot change the clock speed values or fan speeds for either cards in 12.8.

What could be my problem? Maybe im missing something really stupid. Can I even crossfire these two cards with one being 1GB and the other at 2GB?

Thanks in advance to everyone who helps me out here....
