Bagaimana kartu grafis dan perangkat lain mempengaruhi batas memori
Perangkat harus memetakan memori mereka di bawah 4 GB untuk kompatibilitas dengan non-PAE-aware rilis Windows. Oleh karena itu, jika sistem memiliki RAM 4GB, beberapa di antaranya tidak aktif atau memetakan kembali di atas 4GB oleh BIOS. Jika memori sudah dipetakan, X64 Windows dapat menggunakan memori ini. X86 versi klien Windows tidak mendukung memori fisik di atas tanda 4GB, sehingga mereka tidak bisa mengakses daerah dipetakan. Setiap rilis X64 Windows atau X86 Server bisa.
X86 versi klien dengan PAE diaktifkan memang memiliki digunakan 37-bit (128 GB) ruang alamat fisik. Batas bahwa versi ini adalah memaksakan alamat RAM fisik diijinkan tertinggi, bukan ukuran ruang IO. Itu berarti driver PAE-sadar benar-benar dapat menggunakan ruang fisik di atas 4 GB jika mereka ingin. Misalnya, pengemudi bisa memetakan “hilang” daerah memori terletak di atas 4 GB dan mengekspos memori ini sebagai disk RAM.
