Hmmm.. I've tried it with a motherboard which uses an identical chipset
(Epox made) and they work fine.
Maybe there is some issue with the CPU temp - I will have to see if I
can tell the temp on this mobo.
My guaranteed killer is to run
[ vty 1 ]
find -x /bigpart -type f -exec md5 {} \;
[ vty 2 ]
cd /usr/src
while (1)
make buildkernel KERNCONF=GENERIC
end
Which I would guess increase the CPU temp (like a lot of things :)
I will try just md5'ing a small file in a loop which should just make
the CPU hot.
