HyperMemory™
For users of a 32-bit version of Windows: If your computer is configured
with two 2 GB memory modules or more, 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.
