I want to use my onboard HD4200 additional to my HD5850. I don't want to use them as a crossfire system, I just want to use two graphic devices at the same time.
Some month ago it worked very fine with my ASUS M4A88TDV-EVO/USB3, an older driver and Windows 7. I enabled surround view in BIOS, connected each GPU with a monitor and had an extended desktop with the benifit, that my HD5850 uses the idle clock in 2D-mode. I run games only on the monitor connected to the HD5850.
Now I'm using Windows 8 (same hardware) and the latest CCC doesn't supports the HD4200 anymore. To use my HD4200 I would have to install the legacy driver, but once I install the legacy driver it replaces the current driver for the HD5850 and the other way around.
Now my question: Is there any way to make it work again (using the latest driver for my HD5850) ? And how can I do it?
Many thanks an best regards,
