No, there are no X570 motherboards that support 5100 speed memory.

5GHz+ memory isn't suitable for everyday use, especially with Ryzen's Infinity Fabric. You'll still achieve lower latency using 3800 CL14, and you won't have to apply 1.6-1.7V+ to your memory. For your query, the B550 Unify X seems reasonable. If you opt for the X570, it suggests an ITX build. A Strix X570-I would be my choice. Also, 3800 CL14 dual-rank is fine, but if you choose Samsung B-die, it's safe to assume they're dual-rank because the timing is crucial with Ryzen.
Tell your friend to contact the motherboard maker or memory manufacturer. He’s offering you his free personal consulting and tech support.
Hey, my friend isn’t someone who listens to others’ opinions or knows anything about computers. I can just say it’s 5000 and he’ll believe me.
He’ll likely check bios or HWinfo eventually. Running above 3800MHz on Ryzen won’t be feasible due to the infinity fabric limitation.
That would be quite clear, though I’m mainly worried about his memory selection.
He seems unfamiliar with computers and tends to ignore advice. You’re the one who already has your expertise as his personal tech consultant. Just let him know you don’t have the right information and suggest reaching out to the motherboard maker. Avoid recommending boards that claim support for 5100MHz RAM unless they actually meet JEDEC standards. Overclocking beyond specifications is risky and often leads to errors like "CPU overclocking failed." Your 5950X is limited to 3200MHz, and anything higher isn’t worth it.
