You can increase your computer memory by installing memory modules on the system board.
Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see the appropriate specifications for your system in this book.
DDR2 Memory Overview
When installed in pairs, DDR2 memory modules should be of matched memory size and speed. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance. See the label on the upper-right or upper-left corner of the module to determine the module's capacity.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
The recommended memory configurations are:
A pair of matched memory modules installed in DIMM connectors 1 and 2
or
A pair of matched memory modules installed in DIMM connectors 1 and 2 and another matched pair installed in DIMM connectors 3 and 4
NOTICE: Do not install ECC memory modules.
If you install mixed pairs of PC2-5300 (DDR2 667-MHz) and PC2-6400 (DDR2 800-MHz) memory, the modules function at the speed of the slowest module installed.
Be sure to install a single memory module in DIMM connector 1, the connector closest to the processor, before you install modules in any other connector.

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.
NOTE: Memory purchased from Dell is covered under your computer warranty.
Addressing Memory Configurations
If you are using a 32-bit operating system such as Microsoft® Windows® Vista®, your computer will support a maximum of 4 GB of memory. If you are using a 64-bit operating system, your computer will support a maximum of 8 GB (2-GB DIMMs in each of the four slots) of memory.
Installing Memory
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To avoid electrostatic discharge and damage to internal components, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface on the computer chassis.
NOTICE: To connect a network cable, first plug the cable into the network port or device and then plug it into the computer.
Connect your computer and devices to electrical outlets, and turn them on.
When the message appears stating that memory size has changed, press <F1> to continue.
Log on to your computer.
Right-click the My Computer icon on your Windows desktop and click Properties.
Click the General tab.
To verify that the memory is installed correctly, check the amount of memory (RAM) listed.
