Enabling Graphics Card

Not 100%, but I believe you should:

1) go into BIOS and select multi-monitor
2) in BIOS ensure the framebuffer is as high as possible (2GB)
then save

3) switch to the graphics CARD (shut down first) if the monitor is attached to the APU (unless the GPU in the APU is faster which also depends on the DDR4 memory... I'll assume the CARD is faster)

4) start up Windows then the AMD graphic control panel, then enable "AMD Dual Graphics"

Other:
I'd also test a BENCHMARK first that has Crossfire support then repeat after you do this to ensure the score goes up.

Software will look different but above should help.

Note that you only have the same VRAM (video memory) for games that matches the smallest amount. If the video card has 2GB and you could only assign 1GB to the APU's VRAM (in the motherboard BIOS) then you can only use 1GB for games.

Conversely if the card had 1GB there's no point (AFAIK) assigning more than this in the BIOS to the APU's GPU.

Also, some games may indicate the TOTAL amount is being used (like 3000MB) where in reality that might be about 1500MB of the same data for both GPU's. That's just a reporting thing but thought I'd say just in case you got confused on that.
 


Problem is I have an HP, Which has a shit BIOS. Best I can do is enable Onboard graphics. Everything else I need to do has to be through the software. I know older versions of Radeon Software allows you to enable both onboard and dedicated. How can I do that with the new software?
