How can I install the drivers for both cards? If I install one, the Catalyst can't see the other.
Thanks for any help!
Unfortunately, you cannot.
The Radeon HD4850 is not supported under Windows 10.
You can find more information here : Windows® 10 Driver Support for Discrete AMD Radeon™ Graphics Products
Oh, and there is any chance to install under win7. I changed because when i install on win 7 always freezes my PC
The HD4000 series was moved to the legacy support model in 2013. Catalyst 13.9 is the last Windows 7 driver available for your product and it can be downloaded from the AMD web site.
