Without more information on your computer setup, Have you tried updating your old AMD Gpu through Device Manager? In Device Manager under Display, It should show both of your AMD Graphics cards. See what version of AMD driver is installed for your older card. Then manually try to have Device Manager install the proper driver for your card. You can download the R5 drivers manually from AMD Support site. Then use Device Manager to install it from the AMD package driver setup.
Sorry, using Windows 10 Pro.
My only concern was that, like a lot of different software, different versions may have the same named files. I didn't know if having 2 different version of the ATI drivers would interfere with eachother or overwrite eachothers files with their own and therefor break one or the other.
Before I put the other card in, I wanted to check with the community to see if anyone else has done this or if they know if it can actually be done or not.
Well, I suppose the 295x2 is technically xfire, but it's just one card.
There are 3 monitors plugged into that card that get spanned during games.
The 4th monitor will go into the r5 and not be part of the spanning but be a separate little screen from the spanned 3 that sits above the others.
I've managed to get it running with my i7's built in graphics adaptor, but I'd much prefer it to be running on another card.
I came to these forums to ask the same thing.
AMD Graphics Card
AMD HD 6850
Onboard AMD 3000
Windows 10 64bit HOME
Driver version installed
LG FLATRON L1742S
LG FLATRON L1718S
ASUS M5A78L-M LX3
I tried to use both cards but Windows forced the 15.201 version on both cards, the 6800 worked perfectly but the 3000 was not, I managed to force windows to use version 8.9 for the 3000 only and i managed to have one main desktop on the 6800 and an extended desktop on the 3000, but ALL games crashed on startup even the gaming apps like Steam and Battle.net.
The Catalyst control center only recognised the 6800.
