Hello,
I am testing some RAM in an E420R that has known problems. It is
causing intermittent system crashes, and I get errors in
/var/adm/messages periodically that indicate that memory is the
problem.
However, it is not clear to me from the error messages which
stick of RAM are bad exactly. Here is an example:

It prints U1304 U0304 U1303 U0303, does this mean that between two and
four sticks are bad?
Thanks,
