This limitation applies to most chipsets & Windows® XP 32-bit version operating system.
If you want to get 4GB memory for your system, below two conditions must be required:
1. The memory controller which supports memory hole(memory remap) functionality is used. The latest chipsets like Intel® new chipset, or other chipsets and AMD® K8 CPU architecture can support the memory hole(memory remap) function.
2. Windows® XP Pro X64 Ed. (64-bit) or other OS which can address more than 4GB memory.
