The amount of Video RAM can be verified by clicking the Advanced Settings... button in the Display Settings window. For users of a 32-bit version of Windows, 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. User's Manual 1-3
