Question Motherboard for gaming memory

I'm looking for a AM4 motherboard that can handle DDR4 4000+ memory. Anyone have have a good suggestion?
Above 3600-3700 you have to de-synch infinity fabric clock speed to 1/2 DDR4 clock speed. Since the IF is Ryzen's internal data bus it really likes it fast, so de-synching it is not a good idea for system performance

Just about any board should be able to get 3600 with a Ryzen 3000 CPU and decent memory. The most critical factor is the CPU's memory controller silicon quality, assuming you've decent enough memory to do it without crazy loose timing.
