2nd GPU Disabled Under Catalyst Control Centre

RMA'd a 7970m Crossfired laptop with a faulty card, got it returned with a new one, working fine it seems, using 3D Mark good score, crossfire working etc. Decide to do a fresh install of windows and update cards to latest 14.2 drivers but after doing so I cannot enable Crossfire in CCC, no option to at all.
Take a look at hardware specs in CCC and it's saying one of my cards is disabled!?, check everything using device manager, gpu-z and MSI Afterburner all detect that it's enabled.
I run 3Dmark again, scores have dropped to single card scores Weird? Decide to roll back drivers with more fresh windows installs but all of them as far back as 13.9 WhQL show the same issue!?. Nothing in the bios can help me options wise...





Anyone got any ideas?

Pictures included of what I'm seeing.

Thanks

 

If the scores are still good then its just an odd reporting bug and I would not worry.

 

The scores were good before I re-installed windows, afterwards the scores went down to a single 7970m scores....

 

Do you have a crossfire option tab in the CCC?

 

Yes, are you able to access that in CCC?

 

Nope... No option for crossfire. Ended up reverting back to original drivers which got crossfire back but they're old drivers, 12.4! Then retried installing 13.9 same issue again... Disabled adapter...

 

Have you tried a different version? Maybe the latest betas?

 

I've tried multiple versions including the latest betas. The only way to get it back to crossfire working is to use original drivers which came with the laptop but they're only 12.4 drivers!

 

How do you install the new drivers? Over the top of the old ones?

 

No, using Uninstall manager and then Display Driver Uninstaller in safe mode afterwards.

 

That's likely your issue then, install the stock ones and install the new ones on top, it's how they are designed.

 

Try a clean uninstall of the drivers ( guide here). AMD drivers can be temperamental.

 

No luck, tried installing 13.12 on top of stock drivers and "Disabled Adapter" shows up again...

I doubt you can get any cleaner of an install then reformatting the drive and re installing windows no? Which I've done repeatedly, thanks anyways.

 

Hi Fawkon,

I'm going through the same problem.
I have a notebook (clevo p370em) with 2xhd7970m cards in crossfire.
I'm not able to enable the crossfire option.
I've tried the same things (fresh installs of the latest beta drivers and the stable ones, installation on top a the old drivers that actually work but are outdated, I disabled the ulps in the registry).

Have you found a solution ?

I meant for when/if you tried replacing what you currently had per Meaker's suggestion, in lieu of doing it the way you had done so recently:

Interesting problem, though. When running the 12.4 driver with XFire enabled, do you see better scores as though both cards are running?
