"But back to our mystery. Where, exactly, did the other 642 megabytes of my memory go? Raymond Chen provides this clue:
In the absence of the /PAE switch, the Windows memory manager is limited to a 4 GB physical address space. Most of that address space is filled with RAM, but not all of it. Memory-mapped devices (such as your video card) will use some of that physical address space, as will the BIOS ROMs. After all the non-memory devices have had their say, there will be less than 4GB of address space available for RAM below the 4GB physical address boundary. "
Hvis jeg har læst dette rigtigt, så har jeg forstået at windows 32 bit trækker rammene på mit gfx + Bios rom, fra de 4 Gig, og det der er tilbage er de ram jeg har at gøre godt med i selve windows ?.. 😕
