Hi,
my old and sturdy self-built desktop PC experiences irregular system crashes I have trouble debugging. Maybe there are people here who can give me some hints …
It's an AMD Athlon II X4 610e CPU with 16 GiByte of DDR3 RAM on a Gigabyte GA-78LMT-USB3 6.0 mainboard with an AMD/ATI Cape Verde PRO [Radeon HD 7750/8740 / R7 250E]. The mainboard is slightly damaged: the onboard USB-3 connector has some broken pins but there are no short circuits. The connector is unused.
Under normal usage it never occurs but as soon as I try to use … well, multimedia stuff like games or video conferences, crashes can happen. First I thought of a temperature problem but the CPU is at 57° C (sensor lt8620, temp3) when mostly idling and well below 90° C when stressed. I cannot find good values for comparison for this CPU model but all I find shows that it's still in the green area. Maybe it's a GPU temperature problem. The sensor shows around 40° C during normal usage.
I'd like to consistently log the temperatures in a file. Does anyone know what's the best way to do this? I could hack some kind of systemd unit to log the temperature every few seconds but maybe there's a better way.
Re log files. I turned on persistent journald logging. But the logs from "journald -b -1" don't show anything of interest in the last few lines. As the machine completely freezes it might be because journald can't dump its temporary log into the persistent log or something like this. Is there a way to tune this behaviour? Or is it the default and I need to look somewhere else?
I cannot reliably reproduce these crashes. They happen, but the only thing in common is some stress on the video part, either by decoded video streams or by games.
CPU usage is rarely above 50 percent, RAM usage well below that.

This might help with making a sensor log:

The only thing I know of that could help would be the amd-ucode if you're not using it already.

Great! Two actions I can take I haven't taken yet. I'll give it a try. Maybe the situation improves or I get some more data to work with at least. Thanks!
