I know there is endless posts regarding DDR4 for Ryzen, but I am majorly confused. Basically I am ready to build a Ryzen setup. I have ordered a Gigabyte Aorus X370 K7 motherboard and a Ryzen 1700X. I want 3200mhz DDR4 but I want to know which DDR will run at 3200mhz with the K7 and 1700x with no issues. Please can someone advise as I want to order over the weekend. Thank you so much.
