Enabling 2nd GPU without Crossfire

post #1 of 20
Thread Starter 
I'm trying to set up my 6870 alongside my 6950 in non-Crossfire mode, but CCC reports the 6870 as a Disabled Adapter under the Information tab. I simply plugged the 6870 into my second PCIe slot with 11.2 already installed and expected it to work. MSI Afterburner shows the clocks and everything just fine, but the card won't output to a monitor. Any ideas?

Why would you want the second one in non cf mode? My understanding is that it is one or the other. You obviously cant have two default cards makes no sense.

I'm trying to set the 6870 up for distributed computing purposes. Is there really no way to have both cards active in primary and secondary spots? I find it hard to believe that you can't use a 2nd GPU for, say, extra monitors.

Oh. I believe it is possible to do actually, ive read of people doing it using a ati and a nvidia card.

Because the driver is the same, should be easier as well, have you tried to enable the 6870?

Device manager says the 6870 is working properly.

Is there some easy way to check if the 6870 is actually working? Folding@home didn't work but it could be due to other issues.
