Several people contacted ASRock in the last few days. And the reply always was that ECC is fully supported, e.g. https://news.ycombinator.com/item?id=13762950

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.

AMD will use the same die for its server CPUs, so ECC support is on chip anyway. I see no reason why they should turn it off in the Ryzen CPUs launched today.

It looks like you are (thankfully!) right. The CEO of AMD confirmed ECC is enabled on the consumer chips. This is an awesome release overall!

The IMC in almost any Intel CPU also could do ECC, but on most consumer SKUs there's that pesky little configuration flag set by the factory telling it not to. Why? Because Intel can, that's why.

Gigabyte mobos say you can use ecc memory but not run them in ecc mode. "Support for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules (operate in non-ECC mode)"
