Want some more info about the memory issues though.
To put it simply, AMD gurantees nothing over ddr4-2666 speeds. Depending on DIMMs and density, you could be running as lows as 2133. Any speed above that is not guaranteed, and backed only by the mobo maker.

Furthermore XMP profiles for Intel don't seem to work, so people are having to set timings maually.
