Question Ram speed wont change after changing in bios

[amco_krkic]

So i just got a whole new rig and my motherboard ASUS TUF GAMING B550M plus wifi ii
My ram is corsair vengeance 2x 16gb 3600mhz
When i change the dram frequency in bios to 3600 it still is performing at 2133mhz. I tried to enable xmp and manually set it to 3600mhz but still doesnt work. Please help
