With AMD Dual Graphics is Similar to Crossfire. When you have a compliant video card you will have the option to turn it on with the AMD Control Center. There may also be an option in the bios to turn it on. As you have already seen on the AMD web site there is little info/support. They are useless. How hard is it to have a compatibility list? Anyway, it's been a while but I think I had an A10 paired with an R7-250 which worked pretty good. Ahh, it would only work with 1866MHz & above. When I stuck 1600MHz ram in dual graphics was not available. I'll have to have a look for my notes. I did benchmarking as well...
