Shouldn't be an issue then, I went from a Z77 mobo to an X370 one and it just used the W10 license tied to my MS account.
What's are you going to go for next?
I'm not sure. I really like the look of this ram so I may buy another motherboard first and hopefully fix or rule out that as at fault, Then if I still need to return the memory I'll grab whatever's suitable and not too expensive.
