No crossfire option in ccc.

[Captain]

Using a 7990 atm as a stop gap card and I see no crossfire option in ccc.

Advanced view is enabled.

Should there be an option for CF as it's a dual gpu but single card?

Latest driver is installed.

Windows is also seeing both gpu's in device manager.

Any help appreciated.

There isn't one.

If you want to run single card, you have to set up a 3d application profile for each specific game in CCC.
One of the reasons I prefer two 7970's over a 7990 tbh.

I don't want to run single card, I just wasn't sure if CF wad enabled as there is no option.

Thanks

Oh

Yeah, it's running in CF whether you like it or not, but you know that now

Petey nailed it.

It is easy to get the CF option back in CCC, get another HD7990 installed.

What's the scaling like? Could be an option

I hope your cpu and psu are up to the task.

Indeed. I have 2 7990's pulling about 1050w at the wall when mining (undervolted @1.085v), and that's just with the cards, a D5, HDD, 9 fans and a crappy Celeron which pulls next to nothing.
