have you check the memory QVL at ASUS site? Some RAMs listed as single channel only. i recommend that check the list first.
Did not find RAM in that list though.
example My RAM is 8GB Value from Corsair - CMV8GX3M1A1600C11 - the motherboard support single, and dual channel setup, and all 4 slots support.
Just a recommendation, get AMD Radeon R9 memory, if you want confirmed compatibility with Kaveri CPU.
BTW - to enable dual graphics - set the IGP Multi Monitor to Enabled (under NB configurations)
