You may find that your computer is able to support a physical
installation of 4 GB or more memory. However, this maximum
memory may be further limited by the operating system not being
able to address the full range of physical memory.
For 32-bit operating systems, Windows Vista and XP 32-bit editions
can address approximately 3.3 GB. This limitation is present on all
32-bit hardware and 32-bit operating systems
