  This is a limitation of the 32-bit operating system. For more information on this, please see the following Article:

  The RAM reported by the System Properties dialog box and the System Information tool is less than you expect in Windows Vista or in Windows XP Service Pack 2

  The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

   The easiest answer for this question will be:
  Upgrade your Vista to Service Pack 1 (SP1). You still will not be able to use RAM memory over amount about of 3-3,5 GB but your Vista show you all 8 GB

  How can I use the memory above the 3,5 GiB?
  Another question about it: is the swap file a part of the limitation of the 3,5 GiB?
  
  I am now running: Windows Home Premium 32 bit and thinking about upgrade to run 64 bit.

  Goof2000, you will require upgrading to a 64-bit OS, as such RAM limitation is related to the system architecture
