Good catch, but it could be a bad memory socket instead.
Before declaring the module that's out as bad (and buying a
replacement) you need to verify that the socket it came out of are
OK. The easiest way to do that is to move the module that works to
that socket (leaving the back socket empty) and exercising the system.
If that module works in both places, then indeed the one you've taken
out is bad. If not then you likely have two good memory modules and a
bad front socket on the motherboard. (Just to be clear, I don't mean
here that the physical socket is necessarily bad. I mean the whole of
the socket and the circuitry dedicated to driving it.)
A friend had the user-accessible memory socket in a Powerbook up and
fail. He didn't do these steps and was really frustrated when a new
module wouldn't work and had to be returned.
Good luck!
