Ryzen 9950X3D supports ECC memory and is essentially the same chip as the EPYC 4585PX. We could use ECC memory with 9950X3D CPUs if we were willing to pay for it.
Hardware is not very reliable in general and not a substitute for testing. If we had more resources we could do every build twice and compare the outputs.
