[OT]It is a common misconception that 32-bit CPUs cannot use more than 4GB RAM. It is true that they cannot use more than 4GB at a time but that is not the same thing. I used ye good ole Z80 with only a 16 bit address bus (limiting the RAM to 64KB) with 256KB! A decent memory manager is all you need. Edit: In current 32-bit OSes that would translate to a limit of 4GB per process but not a limit to how much memory you can have installed din your machine.[/OT]
