Just wanted to thank you for typing all the info out to to previous poster. My system has been doing the same thing on a b550 auros and this fixed it for now. Unfortunately there was a bios update a few days ago and still getting these errors without your fix. Shame to pay $450 for a processor that can’t run on default settings.
I'm going to wait a few months to see if a better bios comes along, if not I'm going to try and warranty the chip with AMD. I think perhaps their binning verification procedure needs a little work and my processor perhaps shouldn't have made the cut to be a 5800x.
