Ehh, you'll probably want an X470 board.
The X370 Hero in previous tests has shown that it doesn't really like high speed RAM. It runs a T-topology layout, designed to overclock 4 DIMMs well. But suffers when only running 2 DIMMs. I would say the max guaranteed overclock for that motherboard (assuming the CPU can do it aswell) would be 3466mhz. However you might be able to get 3600 to work okay, but don't think it'll run that guaranteed. Especially with how immature the BIOS updates are for 3rd gen ryzen right now.
