Addressing Memory With 4-GB Configurations
Your computer supports a maximum of 4 GB of memory when you use four 1-GB DIMMs. Current
32-bit operating systems, such as Microsoft
®
Windows
®
XP, can use a maximum of 4 GB of address
space; however, the amount of memory available to the operating system is less than that installed.
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.
