This morning AMD is introducing their Ryzen PRO processors for business and commercial desktop PCs. The new lineup of CPUs includes the Ryzen 3 PRO, Ryzen 5 PRO and Ryzen 7 PRO families with four, six, or eight cores running at various frequencies. A superset to the standard Ryzen chips, the PRO chips have the same feature set as other Ryzen devices, but also offer enhanced security, 24 months availability, a longer warranty and promise to feature better chip quality.

I guess it makes sense from a marketing perspective, but I'm not a fan of segmentation like this - it just makes an already complicated market even more complicated.

Just like other Ryzen CPUs, all the Ryzen PRO chips fully support ECC technology, but with certain limitations when it comes to data transfer rates and memory modules — these are peculiarities of the controller and the PRO moniker cannot change them.


It'll be up to the board manufacturers.

And it's worth noting that the existing Ryzen CPU's (at least the Ryzen 7's, possibly 5's and 3's, but not sure about those) already support ECC, you just can't find any motherboards that support it. Hopefully Ryzen PRO will change that in reasonably short order and the OEM's won't be jerks and make boards that only support ECC with processors that identify as PRO models.

I am fairly sure that my ECC is working. I have an ASUS Prime X370-PRO with a Ryzen 1700X and ECC RAM installed. The dmesg reports:

The UEFI does not have options to select ECC Scrub or continue / halt on error, but there are supposed to be ways to set that from within Linux, although I haven't yet.

Ah, looks like scrubbing was already on.
