   When it comes to troubleshooting, any component you can replace/rule out is always
a good call. If you have the same issues on a different board then the CPU or RAM
will likely be the culprit, if it all clears up then it was the motherboard or it's
BIOS.

Good luck and let me know how it goes

	Took the day to go properly over the situation. Single dimm - 4d can occur (rarer then 2 slots) GPU out - no change. Took all nvme drives excpet windows system, same story. Did alot and alot of manual running. Patched 4.1 bios. Did alot ofanual adjustments to Processor droce strengths and impedances - and this greatly reduced 4d occurence. By the end of the day, I spotted 4.2 update. Patched, so far tests go fine... We'll see, too early to tell. What I can confidently say: error occurs only if memory training happened (code 15). Will keep posted. For now slowly gathering info.

	Hopefully 4.20 gets you sorted, the fact that it has followed so soon after 4.10 means it is almost certainly a bug fix release, which is what we want in your case.
