Tony, you are confusing schemes to virtually address modestly more than the 32-bit limit by stretching it to a number some 4-16 times the actual limit for a 32-bit binary number. Apple never played those virtual address games with 32-bit operating systems (starting with MAC OS 7 or 7.1 in about 1991).
A 32-bit binary number can not go beyond about 4.3 billion addresses. The limit for a 64-bit binary number is 18,446,744,073,709,600,000, or about 4.3 billion times more than a 32-bit number. So with your 64-bit OS, you just need to find hardware that can accommodate 18 Exabyte's of memory. (Exabyte is a gigabyte squared.) Thank you, Mark Snyder -----Original Message----- Thanks for the quick lesson. But it has nothing to do with what I said. You probably missed the link Vicky gave which explains it better than I can. Tom never actually told us if previous versions of 32 bit Mac OS have been able to use more than 4gb ram, instead going off on a rant. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
