Isue: Couldn't enable Dual Graphics mode, cannot find the Dual graphics button. currently plugged monitor to discrete due to screen goes blank after restart when plugged to the onboard.
According to the Motherboard documentation you only have two system memory slots, so how have you got four sticks of 4x1GB memory?
This is from the manual.
Dual Channel Memory Configuration
This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth. The two DDR3 memory sockets are divided into two channels and each channel has one memory socket as following:
Channel A: DDR3_2 Channel B: DDR3_1
Due to APU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used for optimum performance.
You need to 2x4GB sticks of supported system memory. Please refer to the Motherboards QVL memory list for compatibility.
Refer to page 10 of the Motherboard documentation for instructions on how to setup Dual Graphics.
Setup of the AMD Dual Graphics Configuration
A. System Requirements
An AMD A series processor that supports AMD Dual Graphics technology
Windows 8.1/8/7 operating system
An AMD Dual Graphics technology-supported motherboard and correct driver
An AMD graphics card that supports AMD Dual Graphics technology (for more details, please visit AMD's official website) and correct driver (For an FM2+ APU, please use an AMD R7 200 series graphics card; for an FM2 APU, please use an AMD Radeon™ HD 6000 graphics card.)
B. Installing the Graphics Cards and Configuring BIOS Setup Step
1: Observe the steps in "1-5 Installing an Expansion Card" and install an AMD Dual Graphics technology-supported graphics card on the PCIEX16 slot.
Plug the monitor cable into the graphics card and start up your computer.
Step 2: Enter BIOS Setup to set the following items under the Peripherals\GFX Configuration menu: - Set Integrated Graphics to Force. - Set UMA Frame Buffer Size to 512M or above. Save the settings and exit BIOS Setup. Restart your computer
There was a typo, it must be 1x4gb not 4x1,
So to enable Dualgraphics i need 2x4gb?
Because i already did the Setup of the AMD Dual Graphics Configuration point and nothing happened.

Correct, you need 2x4GB memory running in Dual Channel mode and both memory chips need to be identical to use Dual Graphics. Please use the Motherboard manufacturer documentation i posted above to ensure you get compatible memory.
