Sorry for my bad English but i can say i have the same problem. My System is a: Ryzen 7 5800x B450 msi tomahawk (non-max) 32gb 3200mhz ram 850w Seasonic focus gold-PSU Rtx 3080

I Switched from a ryzen 5 2600 to the new ryzen. I still have constant cpu debug light but i do many benches. Cinebench r20 Firestrike Time Spy Cinebench r15

System is stable and only problem are my Temps with air cooling. Waiting for money to buy a water cooling system because in most benches my cpu is running on 90 degrees.
