... by trying it out and reporting the results to others, and reading their results and reporting your confirmation. This isn't a thing that the motherboard manufacturer can put in by accident. Anyway. If you need ECC support, you buy an EPYC server and get registered ECC support. If you would like to have ECC as a feature, you get a Ryzen board that's reported to work, and you get unbuffered ECC for one-bit correction and two-bit reporting. Then you overclock it to generate RAM errors, and it shows up in your system log. Then you bring it back down to normal speed. At last report: normal desktop Ryzens (nothing with a G suffix unless it also has a PRO marking) on any ASrock, most ASUS, and some Gigabyte motherboards will support this. To the best of my current knowledge, no MSI motherboards. -dsr-
