I found the that most advertise with EXPO and if you look at the specs state also has xmp (I was exaggerating a bit for dramatic affect). The 285K has plenty of reviews but looking for motherboards to go with the 200 series if you dont want the highend z890 is hard to find.
I'm looking at the Gigabyte Z890 AORUS MASTER, Overclockers did a review last year on it
