Power Macintosh: Memory Test Error Message At Startup (6/97)

I am getting a strange error message on my Power Macintosh computer at startup. It states, "The built-in memory test has detected a problem. Please contact a service technician for assistance." What does this mean?
This is the result of an out-of-spec or faulty RAM card. You should have the RAM card replaced.
