If your computer is congured with more than 3 GB memory, the memory
might be displayed as approximately 3 GB only (depending on the computer’s
hardware specications).
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.
