Enabling 3000mhz in vengeance lpx 3000mhz?

[Ragesh D Antony]

Recently I assembled a ryzen 2nd generation build.
.
In bios RAM showing only 2133 Mhz.
.
I searched Internet came to know to enable xmp
.
My motherboard is B450 A Pro
.
In bios I confused with a setting named A-XMP? It having 2 modes 1 & 2. I confused.
.
How to enable 3000mhz in MSI B450 mobo?

A-XMP 1 or 2 for corsair lgx 3000mhz?

ryzen is picky about ram.
speed depends on the ram construction, how many sticks, the motherboard and processor.

If the ram is on the motherboard QVL list, I would expect better than 2133.
