Installing SIMMs is not just a matter of snapping them in; you have to 
attach/detach the correct resistors or set the jumpers correctly.  This
may have caused the variation in recognized RAM you got.  If you post
your hardware configuration (i.e. what Mac you have), someone can probably
tell you which resistor/jumper setting to use.
