It means the memory sticks (or chips) contain additional circuitry (a
'register' or buffer) to support the massive numbers of memory chips a
server typically contains. Desktop (and some server) motherboards that
only have two to four memory sticks do not need this extra circuitry. Go
to Wikipedia and look at the description of Registered Memory, and
follow it to ECC memory as well.
