Video RAM
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 opearating system cannot address more than 4GB of memory,
these system resources overlap the physical memory. It is a technical
limitation that the overlapped memory is not available to the opearting
system. Even though some tools might display the actual physical
memory built into your computer, the memory available to the opearating
system will still be approximately 3 GB only.
