4GB RAM on 32-bits WINDOWS 8

Hi guys I'm here for 2 sample questions.


1. Microsoft says Windows 8 could use as maximum of ram 4GB on 32-bit, but O.S. only recognize 3GB; WHY?
[I know if I want to use 4GB I need install the 64-bits version of windows 8.]


2. Whatever be your answer, is recommended the use of 4GB  on 32-bit of OS? If your answer is NOT please explain me.



I'm doing these question because I don't understand what's the difference between 32 and 64 bits. I only know the maximum of RAM you can use between each one, and some programs only work with x86 architecture and others with x64 like a servers ,who's use a lot of RAM.



Hi Eduardo,

Welcome to Microsoft Community and thank you for posting the question. I see that you want to know the difference between 32 bit and 64 bit version of Windows. Let me help you with the issue.


I would like to let you know that the main difference between the 32-bit versions of Windows and the 64-bit versions of Windows relate to memory accessibility, memory management, and enhanced security features.


The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.


If you're using a 32-bit version of Windows, the amount of usable memory might be less than the total amount of memory installed. PAE enables 32-bit processors to access more than 4 GB of physical memory on capable versions of Windows and is a prerequisite for NX.
