If you decide to replace one, you could pick one at random and
see if the error goes away.  Since your error is repeatable
you can run the test to see if you guessed right.  Since there
are only 2 DIMMs you have a 50% chance of guessing right the 1st
time and 100% the 2nd time.

Really?  I've always assumed that it was the standard single error
correction double error detection.
