Okay, but let us say I have 4GB of RAM installed.

Effectively what would that buy me? Are you saying that 3GB would be
wasted and not be worth putting in?

Or are you saying that 1GB would be used initially, then at some point
later the machine would magically (or non-magically) recognize the
additional memory giving full value.

I know that answer I'd like it to be.
