RAM frequency changed in BIOS but not applying in Windows (CPU-Z and others)

So as the title suggests,
My Corsair Vengeance 3200 RAM is showing as 1333MHz on CPU-Z and other programs.
However, in my BIOS I set it to 2667MHz (as that lets me boot without changing Voltage)
but its not showing up.
When I go back into the BIOS it still shows 2667MHz with timings at 14-16-16-34 (timings off the top of my head if I remember) and I've tried it at 16-18-18-36 too.
Even in Ryzen Master is shows the Ram at 1333MHz.
Thanks in advance for any help.

MY BUILD:

AMD Ryzen 1700
MSI B350 Tomohawk Mobo
Corsair Vengeance 3200
R9 290 (Im upgrading soon dw)
EVGA 750W Supernova Gold

    this is because the ram is DDR meaning "double data rate". In CPU-Z you actually double what it says and that is the actual speed. 1333* 2 = 2666. This is a common misunderstanding for memory speeds.
