Graphics Crossfiring

Hi Guys,

So I have had an AMD APU (3870k-BE) for a while and got a 6670 HD for christmas to crossfire with it. So I install the card and all seems fine, but then I just start getting blue screens of death.

Is there any reason this might happen other than faulty card? Do I have to go about installing a second card in a particular way?

(I dont know what info you might need, so just ask - All I did was install the card and then run windows)

Cheers,
Bogo

 

It's been awhile since I last set up xfire, and I never tried it on hybrid... but I remember the first time I paired up any gpu was always a fiasco. What I learned was to manually install the driver for each in the device manager, to make sure they both had the same driver and version, then run the installer package over the top to set up the rest of the software, control panel etc. which would avoid bsod. Seemed to always work and would offer the option to use xfire on the first run of the control panel which didn't often happen otherwise. It's probably better than it used to be, but my method still might be worth a go.

 

So, uninstall all drivers - install drivers which work for both cards, reinstall card, install everything else?

 

When do you get blue screens? Randomly, in games, on desktop?

 

Randomly - never before windows has started but once on login, once whilst drivers were installing.

 

Can you even crossfire the 2 as one is effectively in the CPU and one is on the Gpu.

Hybrid crossfire is doable I thought required a 790gx or 890g chipset. You would need this to activate the crossfire.

 

Yep, I can crossfire these two things

 

Right, I would clean everything up first and start over fresh. Make sure to unpack the driver download. Then from device manager you should have 2 entry for the same gpu, select update driver and point it to the driver files for each instance, reboot if needed, then run the installer to set up the control panel and other components. If all goes well you should have xfire option enabled in the gpu control panel and no more bsod. At least you can hopefully rule out a bad driver install if it continue and move on to hardware testing.

 

OK - So I did that, thanks

It now kind of works - there are no more BSODs and the Discreet GFX is working fine. HOWEVER, when I installed the clean drivers, which should work for both the APU and the discreet graphics, it only installed for the discreet card.

I am now going to try getting drivers specifically for the APU and install them too, to see if that works.

 

turns out that Gigabyte, who make my mobo, have something called "surround view" that you need to enable in the BIOS. All done now and hopefully working

Thanks, for the help guys
