It may be this: An Intel devised memory address scheme.

From Microsofts website: Link.

Quote:

PAE - Physical Address Extension - is an Intel-provided memory address extension that enables processors to expand the number of bits that can be used to address physical memory from 32 bits to 36 bits, through support in the host operating system for applications using the Address Windowing Extensions (AWE) API.

PAE support of up to 64 GB of physical memory for applications running on most 32-bit (IA-32) Intel Pentium Pro and later platforms. Support for PAE is provided under the Microsoft® Windows® XP, Windows 2000, and Windows Server™ 2003 operating systems.

Special Windows Hardware Compatibility Test requirements apply to devices supported on these systems.

So assuming you are running one of the above versions of Windows, and assuming hardware permits it (enough memory slots etc) you can have more than 4 gigs of RAM.
