Hi

i'm having trouble setting up dual graphics on my system using a amd a8 6600k and a hd 7750 gddr5 and a asus F2A55-M LK motherboard but i cant seem to get the crossfire option to come up in the ccc.

I have tried using latest amd drivers and the beta drives using driver sweeper and amd driver uninstall each time to change drivers.

I have the following options in the bios for my graphics card and intergrated graphics:

IGFX Multi-Monitor = Enabled (it says it needs to be enabled for amd dual graphics)
Primary Video Device = PCIE/PCI Video
Integrated Graphics = Force
UMA Frame Buffer size = 2G

amd dual graphics can be done with this setup.

unfortunately, the 7750 is not compatible with a8-6600k
so,it can't make a cross fire

the a8-6600k is compatible with 6670 & 6570

the 7750 is compatible with a8-5xxx and a6-5xxx

The a8-5600k is the older apu so i highly doubt that.
I got it to work in the end just needed faster ram. the faster the ram the better with these apus.

bransasko is correct, the 7750 is not compatable with 6600k. Check with AMD website.
