Yes it is, the motherboard is x570 and both slots support pci 4.0 so you’ll get the maximum speed as long as the cpu is pci 4.0 compatible. I bought both the same ssd and motherboard.
According to the product information the motherboard is compatible with this generation of processor. You should therefore not have to do any additional handling.
Unfortunately, we can't answer this question, because we couldn't try it out in such a form. But I'll be happy to post it in the community, maybe a user can help you.
