fx505DU ram upgrade

I want to put another 8gb of ram in my laptop. I can see that the one it came with is a samsung one that runs on 2666mhz (I used CPU-Z to see that) but in task manager it appears as 2400mhz , and I dont know if I should get a 2666mhz one or a 2400mhz. I tried to see if I can change the speed in the BIOS but nothing about RAM appears in the BIOS.

It doesn't accept 2400mhz. I did some research and the mother board in the laptop accepts up to 3200mhz but the processor does not. So if you get 3200mhz RAM your CPU will bottleneck.
