Here's a useful clarification and that few know. For memory RAM, Windows 32bit (xp, View or 7) all recognize around 3,5 gb (there are doubts about it). As systems based on 64bit recognize if I remember to 32GB of memory, Put the big problem and illusion of all is that in fact the Windows either 32bit or 64bit for 2gb only releases per application, Believe it or not, Whatever it. Information that few people know…A way to observe this is in games of last generation, Has no minimum requirement more than 2gb…Then what will make the difference is processor and vga. Make no mistake putting 12gb of memory on a PC that is wasted money.
