Howdy!
I think I have this mostly figured out, but I want to bounce this off the community in case I am way off base.
My "gaming rig" runs unRAID and is spec'd as follows:
ASUS B550-F Gaming
Ryzen 9 3950X
64GB (4X16GB) Corsair Vengeance Pro 3200MHz DDR4
EVGA GTX 1070
2x NVMe SSDs (Currently Removed From System)
2x 16TB WD Golds (Magnetic NAS Storage)
Issue started with unRAID randomly rebooting; never showed anything particularly useful in logs, but it was apparent it was crashing because the array is encrypted, and needed unlocking to continue. Updated BIOS, seemed fine for a bit until earlier this week.
Tried to Install Windows 11 on a SSD, kept getting a WHEA_UNCORRECTABLE_ERROR on certain actions. After a few attempts, Windows did manage to install with a particular Windows 11 ISO (Windows 10 outright refused and failed every time)
When trying to install ASUS Armory Crate (because I have a deep distrust for Windows Update doing driver installs) the system would BSOD every single time with the same WHEA_UNCORRECTABLE_ERROR
RAM has been tested with MemTest86+, max tests, all passed (it runs 10 times)
CPU seems fine, ran Prime95 for a long time (24+ Hours), no issues seem to be apparent there
GPU also seems fine, ran FurMark for a (24 Hours), seemed just fine
Ran AIDA64 System Stability Test on all options, no issues
I am beginning to think it is something with the motherboard, or more specifically the motherboard chipset. It seems to only tank when there are specific actions taken on the system (driver installs), and once an OS is loaded, it is stable when doing stress testing until you attempt to do anything related to drivers.
I have another motherboard on order to be delivered tomorrow, but interested if anyone sees any holes in my logic in thinking that it is the motherboard.
