While 64-bit can handle more memory, unless the 3GB barrier is moved by the
64-bit OS remapping the hardware reservation list (actually moving the
hard-coded address reservations or causing them to look elsewhere) it too is
limited to 3GB.
This can be seen if the machine is setup as a server with a server OS, but
then it becomes a 7GB limit.
Until we drop some of the backwards compatibility in our hardware (EGA, VGA,
monochrome support), get rid of the paging concept, and vendors make the
addressing more flexible with the hardware built onto the motherboard, there
will continue to be RAM barriers.
And, yes, those selling more than 3GB to owners of 32-bit OS are thiefs.
