Two and a half days all is fine, and boom my pc crashed.
Restarted pc, and had scarlett unplugged while shutting down. All is still working fine after the reboot.
Not sure what I want to and or can do.
I am starting to become convinced it was not the Tumbleweed update causing this.
It probably was the rebooting of my pc after the update.
Pc crashes about once in 3 to 4 days. Some times it takes longer.
Most noticeable symptoms, mouse and keyboard stopping to work. Sound (music) often keeps on playing.
Only thing left then, is to hold the on/off switch of my pc for 5 seconds.
I now know that if this happens, I need to disconnect the dac, while shutting down the hard way and rebooting.
As I type this 2 days since last freeze.
Could it be memory related ?
If I set the memory in my bios at 3000mhz, this weird issue happens more often. (the freezing)
The memory should however work at 3000.
Part of the bios that reads the memory also states DDR4-3000 mhz.
The bios sets it to 2133 mhz though.
The Gskill memory site, list my mobo as tested. bios is updated.
Lets start with good news. I updated Tumbleweed and the focus is still working fine after the reboot.
Then about the memory.
With some help from the dutch Tweakers forum, the Linux musicians forum, and me googling, it could be there is too little Voltage on my memory.
XMP.
In my bios XMP is set to auto. When I click this auto, I can choose between auto and XMP2.0 profile 1.
When I pick that profile my DRAM voltage jumps from 1.2 to 1.35 Volt.
Now that is interesting but because as far as I can tell it should be 1.35V.
On a different page in the bios my memory is called 1.35 volt memory.
I learned a lot the last few days.
Jedec and XMP.
XMP is an overclock profile which the motherboards can read from a chip on the memory stick.
For now I exit-ted ed the bios without saving, I first wanted to be sure I fully understood what those setting do.
Tomorrow I will turn that profile on.
Memory, is now running at 3000Mhz. (as it should be)
I went into the bios and changed the xmp setting from auto to a profile listed there.
This made the dram voltage jump from 1.2 to 1.35 Volt, also as it should be.
I will now have to use my pc for over a week or so to know for sure this has solved the instability issue.
Its a fact though my memory was basically undervolted.
I am quite optimistic, that now my pc will be as stable as I am used to with openSUSE.
The tumbleweed update was 99.9% sure not what caused the dac problem.
The rebooting of the pc after the update probably was. But I do now know how to solve this. Unplugged the dac at the pc, count to 10 and reconnect it.
I remember Malcom Lewis (I hope I spell his name right) suggesting me to put more voltage on my ram.
I did back then not know how to do this though, but he was right.
If my pc is still not stable now, I could even try to go from 1.35 to 1.36 volt, but fingers crossed its now solved.
OpenSUSE was not the problem.
It’s over two weeks now, and sill openSUSE is rock stable.
Not a single crash or freeze sine I set that xmp profile. From an DAC issue to a memory fix.
I am beyond happy.
Loving the scarlett solo. A bit better sound but definitely more stereo, then from the dac chip (the onboard sound) of my mobo., when listening on my gaming headset.
Then those speakers (studio monitors) Never knew a pc could sound that good.
One speaker is already more expensive then my head set though.
Maybe its time for a better headphone.
