Addressing Memory With 4-GB Configurations
Your computer supports a maximum of 4 GB of memory when you use four 1-GB DIMMs. Current operating systems, such as Microsoft® Windows® XP, can
only use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than 4 GB. Certain components
within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.
