Are there any Ryzen boards that support ECC and actually correct errors?

  Yes, almost all of them correct single-bit flips and detect but do not correct multiple hit flips.

  As others have replied, all the ASRock boards where I have ever checked the specifications do support ECC and also some ASUS boards support ECC, e.g. all ASUS workstation boards. Because ECC means Error Correcting Code, by definition, any board that claims ECC support must actually correct the errors. The ECC codes used now, with 8 extra bits for each 64 data bits, correct any 1-bit error and detect any 2-bit errors. Very old computers (25 years old, or more) used parity instead of ECC and they just detected any 1-bit error (and any errors with an odd number of flipped bits), without being able to correct the errors.

    Most Ryzen ASRock boards support ECC as well. I'm happily using one right now.

      > Most Circa Zen1 launch, ASRock claimed all of their consumer boards would support ECC.

  Yes. E.g., all ASRock boards.

  The functionality seems to all be in the memory controller integrated to the CPU.
