In that case I will also link this thread again that I put into the PM. The rest of my thoughts I have expressed there.
Wasn’t that a problem with Haswell (?) at one point? Some power supplies couldn’t handle the low power draw and their voltage protection would trigger, causing them to reset.
EDIT: I shouldn’t say same, but a similar-ish problem.
Not iust haswell a lot of OEM systems. Out of the box premiere crashing under load is a thing. It was fixed via updates and microcode which boost the voltage slightly. It’s an ongoing problem. On the dells the temporary fix was also to disable power management but it’s a different issue than ryzen. Disabling power management is always a thing.
I would say maybe something like if after disabling all power management the sytem still intermittently locks up you should look at your Mobo ? Hah?
I’d certainly agree with that.
But to just generalize and say “X problem is ALWAYS Y” (as per @SamX above) without any actual verification/validation is how you end up with broken diagnosis (and possibly say, RMA a good board and wait for replacement when the problem is actually something entirely different - wasting both your time, the vendor’s time, etc.).
Develop a hypothesis, test, confirm result.
I have a laptop with Raven Ridge (2200U). It locks up in Linux after a set time if I don’t turn off C6-states with zenstates.py. Windows can run longer without locking up.
Yeah kinda i guess.
Atleast start to disable all power saving features and go from there.
