If your computer is configured with two 2 GB memory modules, 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.
