A couple of ways - Use a stage 3 install, build the kernel, reboot and
emerge stress.
Then run stress from the command line, with enough parameters to cause
swapiing - at least half 1.5 times physical memory for repeated 5 minute
to 15 minute sessions.
The other way - again a Stage 3, or something like - puppy linux or
other small linux - damn small linux, feather, boot up the cd, bring
down setiathome, fire up the command line in a shell, get top
going in another shell, or gkrellm, and let it run.
If stress or, especially, setiathome lock up the system, then it's a
bad motherboard.
As the KM2M has 2 DIMM slots for each memory type, swap dimm slots
or just pull one dimm out - assuming 2 dimms.
As to power supply - are you aware that cpus and dimms do exert up to 45
A of current draw for micro seconds? Which don't show up in normal scope
viewing of the power supply lines?
What you discribe as symptoms would trigger me to look at, in the following
order -
- poor cooling - not enough air flow.
- Single bit memory error on the upper dimm
- Weak power supply causing voltage sagging
on the memory power rails, thus increasing noise.
- Bad board layout or non-working memory de-coupling capacitors.
