```

I've been trying to fix this issue many times, what I've tried.

* disabling cstates in my bios since people have said its linked to that

* using these kernel params `processor.max_cstate=5 rcu_nocbs=0-11`

Here's my full system specs https://mystb.in/AustriaProcurementHong
and just ask for anything else

edit
So after looking into the motherboard side of things I found this fedora user with the exact same problem as me.

Unlike him I updated my bios weeks ago so I shouldn't be having the issues https://www.asus.com/motherboards-compo … ME-B450M-A

Re: Mircocode crashes on amd ryzen 3rd gen

mce: and microcode: messages might be unrelated and just happen to appear at the same time

as what else though? I didn't mention it in the main post but I also have another computer with ryzen 1st gen i use as a server that has this problem, and each computer runs entirely different software.

Re: Mircocode crashes on amd ryzen 3rd gen

If you edit the boot options so the microcode is not updated (either by adding the option dis_ucode_ldr or removing the initrd entry for the microcode bundle) is the MCE still produced?  The MCE references bank 5,  is the module in that bank known to be good?

im unsure how i would see if a bank is good or not. But this is a history of both mircocode errors i've got

Re: Mircocode crashes on amd ryzen 3rd gen

im unsure how i would see if a bank is good or not.

Have you run memtest on the system?
Edit:
If you use lshw to map the bank to a slot on the motherboard then swap the module in that slot with another module does the error still occur?  If so is it for the same bank or has the bank changed to follow the memory module?
Also is there a message "microcode updated early to new patch_level ..."  if not the kernel is only reporting the detected microcode reversion for each core and the timing would appear to be a coincidence.

The error occurs rarely enough to where I couldn't test something like that without weeks going by. I did run memtest off the arch installer with 2 passes.

Let's maybe  look at the actual problem, what are the symptoms when you experience a crash?
Freeze, reboot, …?

What happens is a freeze on a black screen, I just set up zenstates https://aur.archlinux.org/packages/zenstates-git so hopefully that will help. However I am a little scared to mess with the voltages of anything that arent stock. I have never had good experiences changing those values.
