Hello, I'm planning a custom build (components listed below) and I don't quite understand the relationship between the CPU-supported (max) RAM speed specification and motherboard-supported (max) RAM speed.
Ultimately, this boils down to the following practical question - if I buy DDR4 xxxxMHz RAM, for a system with abc processor and xyz motherboard, will it be a waste because the CPU will restrict its speed ?
Also, I have read a bit about XMP, but that just confused me even more.
My planned system components:
Is there some detail between the lines that I'm not seeing or understanding ? Thanks in advance.

My planned system components:
- Core i9-9900k CPU (up to DDR4-2666 supported ???)
- ASUS ROG Strix Z390-E gaming motherboard (all the way up to DDR4 4266(O.C.))
- Corsair Vengeance LPX DDR4 RAM (either 2666MHz or 3200MHz depending on the answer here)
Is there some detail between the lines that I'm not seeing or understanding ? Thanks in advance.
