Stock came with one 8 gb stick of 3200 mhz which ran at 3200, i replaced with corsair vengeance 2x8gb 3200 and now its running at 2133 because XMP is locked. any help would be amazing.
info on mobo and bios

ram screenshot in cpu-z showing xmp 2.0 and running 2133

also, 90RB000DUS is the model number if that helps in any way.
Thanks
