It would seem the max memory speed for that machine is pc2100.

If you were to remove the pc2100 and install pc2700 it should run just fine but at pc2100 speed. (no diff)

So unless your getting a bargain on the pc2700/pc3200 it might be just as well to go to the above site and get what's suppose to be in the machine.

As for module sizes and what the machine will accept visit the above site.
