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

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? :)
