I guess the Intel motherboards I have are more conservative then. They 
default to the standard RAM profile (slower than what it is sold as) and 
you have to explicitly enable the faster profiles (which do also come 
from data  read from RAM). So it seems like your BIOS vendor is picking 
the faster profile as a default.

I've got a couple of intel systems like this (one windows and one BSD) 
and neither ran stable with the faster RAM profiles.

 From what I read at the time 2133 is the official upper limit of the 
DDR4 standard. Any speed faster than that is an overclock profile.
