Unable to enable AMD Dual Graphics.

[Rahul Sathanapalli]

Before I describe my problem let me provide details about my setup:
CPU:AMD A10-7700k
Motherboard:MSI A88XM-E35
Graphics Card: Sapphire AMD R7-240 1GB DDR5
Ram:2x4GB Corsair Vengeance DDR3(Total :8GB Ram)

So I've been wanting to enable dual graphics on my computer for a long time now and I watched a video saying that for one to be able to do that RAM in dual channel is required so i went ahead and bought the 2nd Stick of 4GB ram but I when i go to Catalyst Control Center(CCC) under the performance tab i only see "CPU Power" and "AMD Overdrive" no option for "Dual Graphics ".
If you look at the Dual Graphics 'pairing' suggestions below I'd think my setup is an ideal combination for this to work.

Link to reccomended APU/GPU combinations

Ive read that one has to change the settings in the motherboard's BIOS and my current settings are :
Initiate Graphic Adapter:IGD
Initiate Graphic Device: Dual Graphics
Integrated Graphics Share Memory:[Auto]
How could i go about enabling Dual Graphics now , because to me its very important as mine is a very low end setup and enabling both APU & GPU to work together could greatly increase my gaming performance.
It would be really great if someone could help me with this as ive been struggling for a long time.

Thanks in advance!!

Your motherboard BIOS may not support Dual Graphics and probably disables it because the GPU is a dedicated high performance GPU and the APU doesn't need to use the GPU and to save power. If you do try to solve it yourself, you may end up damaging your computer.

But my MoBo has a Dual Graphics Setting wouldn't that imply that it does indeed support dual graphics? 😵
