You'll want to run Thaiphoon burner to ID your ICs then use Ryzen DRAM calculator for a starting point. I don't know if the APU memory controllers are weaker/stronger than CPU counterparts but there are countless guides and resources out there for fine tuning RAM. The performance of the graphics component of the APU will be directly correlated to RAM speeds since it uses system RAM so it's worth getting into if you want to eek out maximum graphics horsepower.
