il 32 bit riesce "leggere" fino a 64 gb di ram
L'architettura hardware dei processori x86 con PAE è fornita di linee aggiuntive nel bus degli indirizzi per la selezione della memoria aggiuntiva, in modo che la dimensione dell'indirizzo fisico sia aumentata da 32 a 36 bit. Questo, teoricamente, incrementa la dimensione della memoria fisica da 4 GB a 64 GB.
