You can't really expect anything to work out of the box for 3200+. You might need tweaking of other settings to get your RAM working up to speed. I have a 4 x 16GB 3600MHz kit that does work at XMP, but a 2 x 8GB 4266MHz kit I have requires MANY reboots (5 to 50) to actually POST and be usable at 4266MHz. This may come down to the board being a 4 DIMM slot board. If your board is 2 DIMM slots, like an OC formula or Apex or Gene, you'll have better luck with high frequency kits due to better PCB trace layout suitable for high frequency RAM.
