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.
Installing Memory
1.
Follow the procedures in "
Before You Begin
."
2.
Lay the computer on its side so that the system board is on the bottom of the inside of the computer.
3.
Press out the securing clip at each end of the memory module connector.
4.
Align the notch on the bottom of the module with the crossbar in the connector.
5.
Insert the module into the connector until the module snaps into position.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
NOTE:
Memory purchased from Dell is covered under your computer warranty.
NOTICE:
If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
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.
CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE:
To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
NOTICE:
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.
