Dual Graphics issues

[LizziAS]

I have this motherboard: GA-F2A88XM-D3H plus an a10-7850 and an r7 250 2gb ddr3 and i need a tutorial how to get dual graphics working.

there is a gfx settings

under it is has options for primary video device, integrated graphics, and UMA frm buffer size

 

i set primary device to IGD video.  other choices are nb pcie slot video and sb pcie slot videoe

 

i set integrated graphics to force.  other choices are auto and disabled

 

i set uma buffer to 2gb to match the discrete card memory size

 

then i attached the video cable to the onboard graphics output on the motherboard.

 

AND i get no dual graphics.

 

What am i doing wrong?

After installation of your graphics card, visit the AMD Graphics Drivers and Software Page, to download and install the latest AMD graphics drivers. After driver installation, the option to enable AMD Radeon Dual Graphics should become available in the AMD Catalyst Control Center.   

Once installed, go into the “Performance” section of the AMD Catalyst Control Center and check the box that says “Enable Crossfire™.” This will allow the AMD A-Series APU graphics to work in tandem with the select AMD Radeon™ R7 series GPU.

The latest graphics drivers don't use catalyst control center And there is no such option in spit of having two r7's one discrete, the other apu.  If it were that simple i wouldn't have asked but i do thank you for making the effort.

oh ccc is still alive in new Radeon settings the ccc is now called RAS and is under prefernces, but the crossfire is under gaming--> global settings.

Have looked there.  I'm not sure what could be the problem.  Have posted the question to AMD as well on their boards.  The response is mostly silence.  It's a though they want to quietly forget all about dual graphics mode.

I did run across one post somewhere, but i cant find it now, said that for dual graphics to work that system memory had to be 1866mhz or faster.  But no one else has made that claim.  I'm remiss to buy new memory just to test a theory.

And so AMD has chimed in as to why this issue won't resolve itself as outlined here:
