Isn't DDR5 RAM always somewhat ECC with AMD? https://en.wikipedia.org/wiki/DDR5_SDRAM#Features https://en.wikipedia.org/wiki/DDR5_SDRAM#Features

  As per Wikipedia article, it is not the same thing. The on-die ECC is needed on DDR5 to reach the reliability of previous non-ECC ram. Real ECC-DDR5 additionally exists for higher reliability.

    I think you're getting the reliability even from on-die ECC if there's memory corruption. What you're not getting is warnings that the RAM is bad and that you should replace it. So it's just as resilient as officially ECC ram but you don't know if error correction is happening or not.

      you get no correction for transmission errors
