@VladoPortos Thanks - Mine's working fine again.

Well, I think we can safely say the CPU is fishy New one has UnRaid purring like a kitten...

After trying various BIOS versions as well, I ended up ordering a AM4 socket 5900XT to test with, so we'll see if it yields results as stable or if the problem persists just to determin if it's the CPU or the mainboard right now... So we'll see in 10-12 days time...

No, unfortunately I don't have any AM4 socket CPU's just lying around unused to test with.

Yes I have - thanks for the tip though as most people miss this simple 'trick' during troubleshooting 🫡 Also as I earlier mentioned, I ran memtest86+ for 48 hours straight....which would have revealed errors as well if it was a RAM issue. I've tried turning off XMP without changed results. I've tried with another identical pair from another PC running on Ryzen 9 5900X that runs 24/7/365 without issues ...and yet the same still happens with this Ryzen 9 3900X Both computers runs the same BIOS version F39D on their X570 AORUS mainboards. Only difference is that the 5900X is the Ultra edition and the 3900X has the PRO edition. Both also uses Intel X710-2 (dual SFP+) 10GbE cards On-board LAN is therefor turned off as it's not in use. So I'm hoping someone is able to read from the logs I posted, something concrete that can put me on track as to why this keeps happening? 🤔

Disabling C-State in BIOS caused a crash in less than 8 hours...which is a new record 😅

The odd thing is, this machine and its hardware ran Windows 10 & 11 Pro for years before this without any similar issues. The crashes didn't start until I switched to running UnRaid 🤔

I keep getting MCE's that I don't know how to fix along with the OS crashes. Jan 20 22:22:37 Media kernel: [Hardware Error]: Corrected error, no action required.

I ran a memtest for 48 hours without a hitch just to make sure in the beginning that finished with no problems. I even swapped out my Nvidia RTX 4000 card with a RTX 5000 just to see if it would make any difference and the problem persists. The plugin "Fix Common Problems" also keeps listing this : Jan 21 00:51:02 Media root: Fix Common Problems Version 2024.12.19a Jan 21 00:51:05 Media root: Fix Common Problems: Error: Machine Check Events detected on your server Jan 21 00:51:06 Media root: mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.
