So RAM modules not the problem, that leaves CPU, Motherboard and PSU...

So I switched out the PSU - Fail (really quickly this time... interesting)

So that's when I decided to look at the SDRAM voltage - I looked up the
datasheet for the RAM and compared it to the BIOS setting... Hmm, right
at the upper limit of the spec'd DIMM voltage, so I set it to 1.5V
manually.

Since then it has not skipped a beat (only been ~18 hours, but that's way
longer than previously)

A very well done trouble shooting! you're lucky that during the

Thanks :)

process, your memory module isn't burn out (voltage overload could do
that sometimes AFAIK).

Hmm, the MB voltage was just at the upper limit of the operational voltage
- I think the max. rated voltage goes a little higher although there are
two voltages that must be kept at correct levels relative to each other
(one must always remain less than or equal to the other)

lately many issues surface which tend to has something to do with
hardware, for example the excessive power consumption (ASPM). Sensors
are all we need. Linux could already fetch numbers from SMART, cpu
sensors etc. Maybe we need memory voltage sensors too? :)

Yes, I would love to get all the on-board and on-die sensors working
(temperatures, voltages, fan speeds). This is going to be an 'always on'
media server which will also operate as a part-time dev machine. I would
love to do complete system status logging. Any idea how I could find out
what the correct kernel options I need to do so?

P.S. 24+ hours :)
