Find "4GB-RAMPatch-Multilingual-12.7.2010.exe" and run it.
According to Microsoft it's possible for a 32-bit system to access more than 4 GB of physical memory providing PAE (physical address extension) is explicitly enabled.
With PAE, the operating system moves from two-level linear address translation to three-level address translation. Instead of a linear address being split into three separate fields for indexing into memory tables, it is split into four separate fields: a 2-bit field, two 9-bit fields, and a 12-bit field that corresponds to the page size implemented by Intel architecture (4 KB). The size of page table entries (PTEs) and page directory entries (PDEs) in PAE mode is increased from 32 to 64 bits. The additional bits allow an operating system PTE or PDE to reference physical memory above 4 GB.
Seems this might be a safer option than trusting some hack. Physical Address Extension (Windows)
