AMD Ram Issue?

Hello all,

I have just build my PC and everything seems to be running smoothly except for one thing; when I try to overclock my ram to its speed of 7200MHz nothing happens. It stays at it's speed of 4800MHz. Anyone know why this may be?

My CPU is a 8700X3D and my motherboard is an MSI Carbon X670-E. I double checked and my ram is definitely on the list of compatible ram.

Thanks for reading!
