AMD Dual Graphics on a asus motherboard?

post #1 of 7
Thread Starter 
Hi I'm trying to setup AMD dual graphics on my Asus F2A85-V motherboard but i cant seem to get the dual graphics option to appear in catalyst control center.

I have a a8 6600k richland apu and a saphire hd 7750 1gb gddr5 and i have seen people accomplish dual graphics with that setup and a Asus motherboard (http://www.youtube.com/watch?v=GnipAljJrKk).

current north bridge settings from bios:

IGFX Multi-Monitor = Enabled (it says it needs to be enabled for amd dual graphics)
Primary Video Device = PCIE/PCI Video (IGFX is the other option)
Integrated Graphics = Force (Auto is the other option)
UMA Frame Buffer size = 1G (it goes to 2G but i think your meant to match your discrete gpus memory).

that's all the settings i have changed have i got one missing somewhere?

i have my monitor plugged into my graphics card.

cheers

Do both the on board video and the add on video card appear in Device Manager?

Hi

eventually found the problem after wasting hours of my time trying lots of different things and it turned out to be my ram. i tried my brothers ram in my pc and the option now appears in ccc for amd dual graphics!!

would anyone be able to tell me why it worked with this other ram so i know what to buy.
The ram that worked was 2 sticks each 2gb 1600mhz speed where as the ram which didnt work was 1 stick of 4gb 1333mhz.
is there some sort of requirement for dual graphics from the ram.

Not having a dual channel configuration might have affected the option. You'd be effectively halving the iGPU bandwidth and it'd probably run like garbage, not to mention 1333 is really, really slow for this platform.
