Does Ryzen Apu still benefit from 4ram sticks?

I want to add 2 more ram sticks to the already existing 2 ram sticks which are 2400 OC to 2666.
Since Ryzen APU benefits from Dual Channel ram will addition of 2 more ram sticks keep the same performance or degrade it?
My Ram is Adata 2400Mhz and I will add same model 2x 4gb 2400Mhz to make total of 16gb 2400 OC to 2666.

Motherboard is Ga-ax370-gaming rev 1.x
Cpu is R5 2400G

But this article says something that single rank and dual rank ddr4 are clocked automatically to 2133 and 1866 :O
