Random reboots on AMD Ryzen 9 6900HX with Radeon Graphic

As the title says, I get random reboots on a Minisforum UM690 with AMD Ryzen 9 6900HX and a Radeon Graphic processor.

This happens a few times per day, and it is likely related to using a QHD monitor (2560x1440) along with a 1920x1080 monitor.  I tried different QHD monitors, and I had the same problem.  Once I revert to my 1920 x 1080 dual monitors, the problem goes away.

Another thing, it happens when I am using IntelliJ-based products; it doesn't happen if I am gaming or stress testing it. I also did a memory test, and everything is OK.

I don't see anything suspicious in the dmesg logs; I don't think it has time to write anything; the system just reboots.

Does anybody have any pointers on how to tackle this, please?

if its just a clean reboot without any hardware errors, as in just a straight shutdown, then it could be a power supply issue. might be drawing more power than what the power supply can offer.

It does look like a power outage, the monitors go off, and the system just boots like nothing happened (except the filesystem is corrupted). I already lost a git history because it happened precisely when I committed something.

I ordered a second FQD that should arrive early next week; I expect the reboot frequency to increase.

Is there a way to measure the power it is drawing and fix it?

a ups with a built in power meter or one of these things: https://www.amazon.com/P3-P4400-Electri … B00009MDBU

are you using PBO or is there any overclocking stuff enabled, even by default by chance, in the bios? if the bios settings have an ability to change the tdp, you could try lowering the tdp and see if that fixes it. maybe they set the tdp to its highest or something and the power supply is struggling to provide enough power for it or the transient spikes.

I didn't overclock it, and it doesn't look like BIOS has too many settings. I will double-check it tomorrow when I get home.

I bought a device that measures the consumed power and another power brick. Hopefully, I will find a solution.

Thanks again.
