Well you can stick the old ram pins-to-pins with the new ram
and thereby answer the number-of-pins question with a quick
glance rather than having to count.  Basically, if it fit without
forcing it must have had the correct pin count.

Second there is a bus-speed factor,  and that is usually specified
in the specs.  machines with a 400mhz bus may be too fast
for ram that was designed for something slower.  This too can
be found in the specs.

Will it work with just ONE SoDimm installed?

What model is the machine?
