That's good information but still doesn't tell us that these cpus support ECC, right? Maybe the motherboard fully supports ECC when used with a future 1800X-PRO but not with the 3 chips reviewed here.
In that case anandtech saying "We know that it is disabled for the consumer parts" and ASRock saying "ASRock AM4 motherboards fully support ECC function" can both be true.
