Mathemaica 5.2 are the 64 Bit an illusion !!!....?

Verified to fund both on Windows that on other OS : Mathematica 5.2
and the 64 bit are an illusion. You try on any system to create 4
numerical random matrixes of 10^4*10^4 elements (they should occupy
around 4GB.Mathematica uses the packeds array in which every number of
car occupies 8 bytes) but.... mathematica interrupts the calculation
for lack of memory . A tool that it affirms to be to 64 bit doesn't
have to do this...... or no?

Thanks for the help

Rob
