Output of: watch --interval 0.1 sensors

My BIOS offers no options regarding GART and Spread Spectrum as far as I
recall. Here is my exact motherboard model, in case anyone has extra info on
what its available BIOS settings mean which I may have missed.

That is indeed a difference: Everyone else reporting those crashes seems to be
able to record a Kernel panic, but in my case the system records nothing as it
fundamentally stops functioning at that very moment.

I logged into SSH from my other machine and ran "watch --interval 0.1 sensors".
Attached are my readings at most 0.1 seconds before the freeze, which seem to
capture every relevant voltage and temperature available. Obviously there are
no fans in slots 2 and 4 which is why they show 0 RPM.
