you should be able to use this (Samsung b die)
https://www.overclockers.co.uk/team...3200mhz-dual-channel-kit-black-my-08l-tg.html
if it doesn't work at 3200 then you can turn it down to 2933 MHz (quoted speeds for the 2700x and your mobo).
Then you can tweak your memory timings - download the "Ryzen DRAM calculator" and get it to calculate the settings and plug those into your BIOS. In the calculator rather than saying you have 3200mhz memory you could call it 2933mhz if needed and it will calculate the timings accordingly.
