Yep, totally. I've worked on hundreds of systems and less than 20 of the
workstations or PCs have been useing ECC. Most servers do, but not even
all of them.

A MCE is triggered by an ECC error - no software involved. A good trap

Erm, it was bad RAM everytime it happened to me. On standard PCs, you
don't see those because you don't have ECC and the error is simply not
detected.

Hi Juhan,
After searching the archives of the list I found some similar reports
from September and December 2000 but as far as I understood
the cause of
the error was blamed on the CPU. Is this the most probable case?

Strange - definitely, strange.
You get SIG11 errors when running programs(kernel compile seems to be agood
example), you get crashing processes, you get all sorts of weird funnies but
you really shouldn't get machine check exceptions.
I don't think there is a way a machine check exception can be triggered by
software -
