I done it as well, but I get boot loop once tho, on my G.Skill Flare X 3200 (16Gb Kit) on my Ryzen 1700, from my Crosshair VI Hero Board. I hope May Update allows my Flare X 3200 and the board to work effectively.
I know on my other board on the Gigabyte x370 K7, it did run into that issue like that, but that was when I had the other Ram. When I put the Flare X into it, I did recall it having a boot loop on one of the bios until I updated the 2nd Bios along with it as well (If use XMP, it will come up with Rom Image update denied). At the moment they are finding out on that, it was prob an AMI code bug.
