В первом приближении: количеством процессоров от количества памяти :-)

PAE X86 Technical Reference

Physical Address Extension (PAE) X86 is one of two technologies that
increase the amount of physical or virtual memory available to
applications. The other technology is 4-gigabyte tuning (4GT). For more
information about 4GT, see "4GT Technical Reference."

PAE X86 allows applications using the Address Windowing Extensions (AWE)
API set and running on a computer with more than 4 gigabytes (GB) of
physical memory to map additional physical memory into the application's
virtual address space. Applications not using the AWE API set can also
benefit from PAE X86 because the operating system uses the larger
physical memory to reduce paging and thus increase performance. This is
of particular benefit to consolidation servers hosting multiple
applications.

Note

PAE X86 is not required on the 64-bit versions of the Microsoft Windows
Server 2003 family.
