As someone already said, this is normal. You need a 64 OS if you want
to use all the 4 GiB. And for that, your computer needs also needs to
be 64 bit.

You could always try a 64 bit Ubuntu Live CD/USB stick if this works
on your computer. There are, however, still some issues running 64 bit
Ubuntu, as far as I know, but since I can't run a 64 bit OS on my
laptop I have no experience.
