Your Ryzen 5 2600 is overheating significantly.
Your Ryzen 5 2600 is overheating significantly.
Launch Windows and observe the temperature. The 3900X reaches 70°C in BIOS, yet only 32°C during idle in Windows.
Occasionally it can happen. Still, make sure the cooler is set up correctly.
This setup is now operating at 94-95°C with maximum CPU fan speed. I'll check again to confirm it works on Windows.
I adjusted the settings slightly more and it now runs better, which might explain the improvement.
There might be issues with the BIOS. Have you installed the newest version?
