[Nottingham] Arch always on system freezing

[Martin]

Brian,

That's a good test list and a good find!

Good you have it fixed with the OC-style voltage tweaking...


Aside: I've had CPU heatsinks that appeared to be 'clean enough' yet in
reality were choked with dust behind the fan or deeper in the cooling
fins. That has become more of a problem/feature with the later heatsinks
that have some overly fine pitch fins that appear to be below the
critical spacing that sees dust get jammed fast rather than blown through...

And beware the old degrading electrolytic capacitors that inexorably
degrade that then reduces the supply noise margin until you suffer
phantom random reboots... (More volts can be a temporary fix.)


Thanks for noting the fix.

Good luck!

Cheers,
Martin
