Hi,
I do have Gigabyte Gaming X 570X with latest bios F12e and in slot A2 and B2 when i put the ram with enabled X.M.P. all works fine till i run some games like WOW or Gears Tactic. Most of the programs and games works fine some don't. When I do set it to default 2133 all works stable. Just ordered new ram and will see how it perform with above settings.
