Crimson: A10-7850K + R7 250 dual graphics not working

Jump to solution

Hello,

I have recently updated my driver to the Crimson driver, what i noticed is that my FPS has dropped and the dual graphics fail to work. Tried to enable it in the "Additional Settings" to open the classic CCC. There was no tab to enable crossfire/dual graphics. Is there any other way to enable the dual graphics?

I like the new interface, but if there's no solution, i might just have to re-roll back to the older drivers for now.

Can anyone help me with this?

Your memory needs to be running at 1600Mhz in the Bios, or 800Mhz as shown in the second screenshot. Check your bios settings.

is this fixed yet?  I'm downloading a legacy AMD Catalyst 15.7.1 driver from a third party site because AMD won't support legacy users with a cpu and video card only 2 years old.  If it is a virus I will hold AMD responsible.

Still no option for crossfire or dual graphics after DDU wipe and Crimson update.

Radeon R9 Gamer Series RAM confirmed Bios setting at 1866 or more.

What system memory are you using and is it running in Dual Channel mode? CPU-Z should be able to confirm if it's running in Dual Channel.
