Now I`ve read that those most likely caused by corrupt win files bit it is a clean install and sfc didnot show anything. Although I did get a black screen during windows install setup.(strange) never got one before.

Tested with 12900K +avx workloads enabled.

The error comes up second time already.

Ideas?

What is the problem which prompted you to test the CPU and RAM ?
Does Reliability History have any entries covering the situation?
Can you uninstall the test programmes and then run,in this order, ---dism /online /cleanup-image /restorehealth ---followed by ---sfc /scannow ---and run sfc until it gives a zero report..
For dism,you must have a working internet connection.
