    Windows esetén már rég túlnőttük a 32 bites limit(ek)et, csak nem szembetűnő.

    Először is, amiről beszélünk (pl. innen; az első kettő a Feladatkezelő megfelelő oszlopainak kiválasztásával követhető):

    Pool Nonpaged Bytes: these represent allocations directed to the nonpaged pool, which is a set virtual memory pages that always remain resident in RAM. (These are nonpageable bytes.) Device drivers and the OS use the nonpaged pool to store data structures that must stay in physical memory and can never be paged out to disk. (For example, the TCP/IP driver must allocate some amount of nonpaged memory for every TCP/IP connection that is active on the computer for data structures that are required during processing of network adaptor interrupts when page faults cannot be tolerated.)

    Pool Paged Resident Bytes: Most virtual memory pages that are acquired in the Operating System range of virtual addresses can be paged out. The Pool Paged Resident Bytes represent memory locations from the pageable pool that currently reside in RAM.

    System Cache Resident Bytes: the system’s file cache occupies a reserved range of virtual memory addresses, some of which may currently reside in RAM. (Cached file segments can also be non-resident, in which case they must be fetched from disk when they are referenced by executing processes.) System Cache Resident Bytes represents segments of the file cache that are currently resident in RAM.

    Ez magyarázat a Vista sokkal nagyobb (és az XP x64 néha megugró) memóriahasználatára, illetve a x64-es Windows-ok 'látszólagos' gyorsulására.
