Addressing Memory With 4-GB Configurations
Your computer supports a maximum of 4 GB of memory when you use two 2-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.

you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module.
Otherwise, your computer may not start properly. You should install your original memory modules in pairs either in DIMM connectors 1 and 2 or DIMM
connectors 3 and 4.

To avoid damage to the memory module, press the module straight down into the connector while you apply equal force to each end of the
module.
