My components:
Ryzen 1700x @3.9GHz 1.36V (previously 4GHz)
B350 Tomahawk (latest BIOS)
I conducted two tests, and both appear to fail under normal conditions.
1) I set my MOBO to auto and adjusted it to 4GHz.
2) I raised the CPU voltage to 1.37V~ (close to 1.38).
My first test worked until heavy use began. VRM temperatures were much higher than expected, around 60-76°C within 10 minutes. Since it was in AUTO mode, I thought that was the issue.
In my second test, I increased the CPU voltage slightly and got the same result as the first test, but it didn’t last more than 10 minutes.
What could be wrong? Is the CPU voltage too low or too high? The VRM cooling seems adequate, but could those temperatures be problematic? Or have I exceeded the limits of both MOBO and CPU?

Black is unstable; start with 3.8G and 1.35v. Run half an hour on prime95, watch CPU temperature, stop if it goes above 85.

1. 1.45v is clearly a line you shouldn't touch.
2. Successful booting doesn't guarantee a stable OS. Have you run any stress tests such as prime95?
3. What's your take?

1. 1.45v is definitely a line you shouldn't cross.

3. What's your plan?
I spent about 10 minutes on Prime95 and my whole screen went black completely. The same happened with CPUz. I'm using the Corsair H100iV2 with Thermal Grizzly paste, lowering the temperatures by 7°C. It's strange it turns off after reaching a certain point or when limits are hit.
