If your computer is configured with more than 3 GB memory, the memory 
might be displayed as approximately 3 GB only (depending on the computer’s 
hardware specifications).
This is correct because the operating system usually displays the available 
memory instead of the physical memory (RAM) built into the computer.
Various system components (like the video adapter’s GPU and PCI devices 
like Wireless LAN, etc.) require their own memory space. Since a 32-bit 
operating system cannot address more than 4 GB of memory, these system 
resources overlap the physical memory. It is a technical limitation that the 
overlapped memory is not available to the operating system. Even though 
some tools might display the actual physical memory built into your computer, 
the memory available to the operating system will still be approximately 3 GB 
only.
