[SOLVED] why is my vengance pro 3600 running at 1333 even though I went into the bios and changed it(asrock x570 steel legend)

I have the vengance pro rgb ram at 3600mhz but it is running at 1333.
Why?!?!?

The MB probably didn't like the ram at that speed and automatically returned to stock speed.
