How do I enable dual graphics with my following information?
Cleared previous drivers with DDU. Installed APU Crimson 16.3 with dGPU removed. Installed dGPU. Still no option for crossfire or dual graphics. R7 250 shows up in Crimson but shows as disabled.
Instructions from motherboard manufacturer:
There is no dual graphics under the bios option. The new bios have option hidden.
sorry about the confusion.
AMD Dual Graphic
To setup dual graphic, it’s required both CPU and VGA card must be match/paired.

Below is sample image form AMD website.

Solved! Go to Solution.
Try installing crimson with both the dgpu and APU inserted.
Make sure that your hdmi or vga cable is connected to your dgpu and not into the motherboard itself
Thanks for the post. We are currently investigating reports of Dual Graphics being disabled and the option to enable Dual Graphics is missing from Crimson/Additional Settings.
Please refer to the Motherboard documentation page 28-29 to ensure you have configured Dual Graphics correctly.
Interesting. This is contrary to everything anyone else has suggested. I will uninstall all drivers with DDU and try again tonight and post back with results. Although I feel as thought I included this in my permutations, you never know.
Yes amdmatt is correct, if your R7 250 has 512 shaders and is based on cape verde, it is not compatible with dual graphics.
If your R7 250 has 384 shaders and is based on oland then it is dual graphics compatible
So essentially the 250 is acting as only a dGPU.
If I go the dGPU route, what can I do to get the most functionality out of the APU if I'm not ustilizing the graphics section of the processor for dual graphics?
Thanks for the confirmation, this is the cause of Dual Graphics not working correctly.
