5xxxG are also known for missing official support, only PRO favors have it.
Since ECC is for robustness I'd really prefer when both AMD and ASUS/ASRock/Gigabyte/MSI/... mention ECC support in the specification. Last time I've checked, only ASUS did mention it for consumer AM5 mainboards. (Gigabyte did it for (at least) one simple but expensive server mainboard.) While for AM4 it wasn't such an issue for other manufacturers too.
