Kernel-Power on stock Ryzen 5 3600 (random shutdowns)

When power in wall outlet is off, Windows cannot notice it. But during following boot windows can determine the previous turn off was unexpected. And this cause Kernel-Power 41 too. See a link I gave above.

If you have unstable power, try to use UPS (uninterruptable power supply),just select it properly. Cheap models may operate incorrectly if your PSU has active PFC.

The problem may occur not during heavy load but during transient processes when the load changes significantly.
And there may be problem not in PSU itself but in VRM module (CPU voltage convertor) on motherboard. Unfortunately this occurs sometimes with B450 motherboards especially. That's why I suggested to disable CPU power saving modes in BIOS (!) not in Windows. Please disable AMD Cool & Quiet, Global C-State Control and check if this helps.

Thank you very much for the answer. While testing with the preset you recommended.
The other day I burned through the system on OCCT and wrote down the logs in HWinfo + looked at 
the CPU-Z, everything is fine. Stress tests are passing.

Another question arose. It is rather not on your part, but on the railroad, but AMD has not yet 
answered me, I will ask you. 

Am I right in thinking that if the voltage readings are too high on the RAM, then this is not a 
program/not Windows, but most likely from the processor?
Why am I talking about this? In manual and the description for my DDR4 indicates 1.2V at 2400 
and 1.35 at 3200 (ХMP). I decided to experiment with the RAM. Exposed 2400, as in stock. The flight 
is normal, but the performance has dropped. I understand that in this bundle there may be a motherboard,
a processor, and memory, you cannot say for sure, but still, if the memory does not start at the 
declared 1.35, but shows 1.365, is this considered the norm? Could this be the reason for that very 
error? As an assumption - the system does not hold this voltage, protection is triggered. Then the 
problem is not in the software (in Windows), but in the hardware or not?

Is this voltage considered normal for the processor / memory and why is it that it is higher than 
normal? And can Windows somehow influence this from the side of software and interaction between 
hardware? I specially selected the configuration so that the memory started up immediately at 3200, 
but it turns out that a whole set of procedures needs to be carried out, which is strange, given that 
the 3200 frequency is declared as certified. The question remains in this. 
Could Kernel Power be because of this?

Hi Ruslan,
My name is Igor, I have 12 Microsoft MVP awards. It's a pleasure for me to help others and I'll do all my best to help you. I'm sorry you have a problems.

Kernel-Power 41 (63) error mostly means the problem with power supplying. Can you replace power supply unit for checking? It may mean problems with power management in BIOS or motherboard too.

And you may try to turn off all CPU power saving modes in BIOS (different C states) to check if the problem is in motherboard.

Hello, Igor, nice to meet you.

I thought for a long time and wondered about a weak power supply, but it seemed strange to me that the Ryzen 5 3600 processor, which, according to the passport, takes from 65 to 90W + 550W video card + other system elements, would overload my power supply by 750W. Even if we take the maximum peak = 550W on a video card, then 750W still does not work. Plus, I used various calculators to calculate the power consumption of my PC, an average of 450-550W came out, with another 200-300W in stock. Could this be the case? If so, how to navigate when buying a future power supply unit, if the manufacturer writes "conditionally", take it for 800-900W or what? I just do not want to take an overly powerful PSU, which will use 500-600W, and the rest will be disposed of in vain. After all, the calculation is taken by "rough" summing up the powers, it turns out just ~ 600W, but not enough.

It won't be possible to replace it in the near future, it means you need to choose a good one and which will definitely be enough, but I still don't know what power to even take, if using calculators it does nothing.

In BIOS, I set the following parameters responsible for the power consumption of the processor and turbo boost. All according to the recommendations from the community.

AMD Cool & Quiet, Global C-State Control, CPPC, CPPC Preferred Cores as Enable, first time they were AUTO or DISABLE. Power Suply Idle Control as Typical, was also in AUTO mode.

That is, I did not set any energy-saving modes, moreover, in the AMD power supply I choose balanced, alternating it with the Windows power plan, which is also balanced. Tried the best performance too.

I turned off the fast boot of Windows, removed the automatic shutdown when an error was detected, I will wait for the error to appear so that the log is written.

From the link above, what you provided - I have scenario # 3.

In addition to the PSU, can there be something else? Suppose a driver for a network card or other hardware? Some also write about it. And in general, how can this be related.

Thanks you.
