Hey,
I'm trying to get my crossfire for the two 1GB Galaxy 6950s to work, but unfortunately it is not. I tried uninstalling everything related to ccc, removed the drivers for both graphics card, and had windows detect both cards and reinstall ccc v.11.12 and the profiler, but there was no option in the ccc to enable crossfire after reinstalling. I checked the device drivers, and both cards were detected by Windows, and GPU-Z picks up both cards, and says that crossfire is disabled.

If you need anymore information please ask, I'd be glad to help towards getting me an answer, because I'd really like to get this to work.

Thanks,

Try to disable Lucid support. And then try to CF them.
Meaning the iGPU rendering settings....in the BIOS

Another Note, the New CCC seems to be very unstable when it comes to crossfiring cards. A lot of people have had problems. I would suggest using the last one in the 10.XX Series for the time being.

how did u link your vid cards?
you should have 2x xfire cables connected to them.
Your windows should have detected 2x vid cards.
If you go into "DEVICE MGR" in windows you should see 2x amd 6900x series under the display adaptors tab.

The catalyst drivers need to detect both vid cards b4 you can enable xfire. You will need to chk if windows actually detected both into your system

Okay, I uninstalled the latest version of ccc, and install 10.12 version of it. Next I'm going to go into the BIOS and change that option, and I'll let you know if I even have the option to do it in the ccc, but thank you for your help.

Yea, no luck. I'm just going to try and call AMD Support.

Anything I do, I can't even get the OPTION to turn on Crossfire in the ccc.
This is just the stupidest thing, I can't even.

Do you think I should buy a better motherboard that supports more than x16 and x4? Is that the problem?

Actually the best solution for that Mobo would be a Dual GPU Card. Like the coming next year HD7990 or the HD 6990 or the one and only HD 5970...... we all know as the Worlds Fastest Graphics Card :) .
Yes, you could go in for a better board of course.The same board just the PRO version would have been a better buy...

Or the V Gen 3

Of course both boards are a little more expensive than the present one, but between themselves their isn't much difference.
