Die 4-GB-Grenze (auch 4-GiB-Grenze) bezeichnet die maximale Größe eines Adressraums (zum Beispiel des Arbeitsspeichers), der mit 32 Bit großen Adressen bei byteweiser Adressierung verwendet werden kann, zum Beispiel durch einen Prozess unter einem 32-Bit-Betriebssystem. Manche 32-Bit-Architekturen können mittels Segmentierungstechniken einen größeren Adressraum bereitstellen. (de) In computing, the term 3 GB barrier refers to a limitation of some 32-bit operating systems running on x86 microprocessors. It prevents the operating systems from using all of 4 GiB (4 × 10243 bytes) of main memory. The exact barrier varies by motherboard and I/O device configuration, particularly the size of video RAM; it may be in the range of 2.75 GB to 3.5 GB. The barrier is not present with a 64-bit processor and 64-bit operating system, or with certain x86 hardware and an operating system such as Linux or certain versions of Windows Server and macOS that allow use of Physical Address Extension (PAE) mode on x86 to access more than 4 GiB of RAM. Whatever the actual position of the "barrier", there is no code in operating system software nor any hardware architectural limit that directly imposes it. Rather, the "barrier" is the result of interactions between several aspects of both. (en) |
