An app doesn't necessarily have to require lots of RAM to benefit from 64bit address space. For example, a certain database process might benefit from accessing, say, 8 GB in its address space, but only actually using 2 GB of physical RAM. Such a process runs fine on a machine with 2 or 3 GB RAM, but it has to be a 64bit system. It won't run on a 32bit system, even if it had 8 GB RAM or more (accessed via PAE).
