Maximum system memory size and speed are
depending on the model you purchased.
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.
