I bet the speed of the on-board RAM is extremely slow, So of course when you expand it, its still running at the speed of the on-board RAM.
Kinda like mixing DDR400 with DDR266. it runs at 266.
Which is precisely why when you remove the RAM, or replace the RAM with faster RAM on-board, it speeds up tremendously.
