Indeed. I'd started to add an aside to the effect of 'ten years ago it was probably easier to go ECC'. I'll add it here instead.
A decade ago if you wanted ECC your choice was basically Xeon, and all() Xeon motherboards would accept ECC.
I agree that these days it's much more complex, since you are ineluctably going get sucked into the despair-spiral of trying to work out what combination of Ryzen + motherboard + ECC RAM will give you actual, demonstrable* ECC (with correction, not just detection).
Sounds like the answer is to just buy another Xeon then, even if it's a little older and maybe secondhand. I think there's a reason the vast majority of Supermicro motherboards are still just Intel only.
