can I use different rams?

[WhereHere1]

ok so I am able to buy 4 different 16gb 3200mhz RAM sticks.

They are all completely different makes.

Would they work together? Somebody here must have tried it? If so what happened?

Oh, well my mb takes dual ram, so what if I just have two different sets?

Say 16gb x2 (3600mhz) and
4gbx2 (2400mhz) in the other?
