Steve,
fyi: I posted a week ago:

no responses here, so I checked on fedora-forum: see some info there:

I still don't know if this is a true indication of bad ram, or is it 
just that the module is loaded incorrectly when I don't have ecc ram ?

Note that on my machine, the /proc/mc folder/stats does not exist.
Do you have such an interface ? what does it say ?
