Memory
You can increase your computer memory by installing memory modules on the system board.
Memory Overview
Memory modules should be installed in pairs of matched memory size, speed, and technology. If the memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of the module to determine the module's capacity.
NOTE: Always install memory modules in the order indicated on the system board.
The recommended memory configurations are:
A pair of matched memory modules installed in connectors DIMM_1 and DIMM_2
or
A pair of matched memory modules installed in connectors DIMM_1 and DIMM_2 and another matched pair installed in connectors DIMM_3 and DIMM_4
If you install mixed pairs of DDR2 667-MHz (PC2-5300)and DDR2 800-MHz (PC2-6400) memory, the modules function at the slowest speed installed.
Be sure to install a single memory module in the DIMM_1 connector, the connector closest to the processor, before you install modules in the other connectors.
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 connectors DIMM_1 and DIMM_2 or connectors DIMM_3 and DIMM_4.
NOTE: Memory purchased from Dell is covered under your computer warranty.
Addressing Memory With 8-GB Configurations
Your computer supports a maximum of 8 GB of memory when you use four 2-GB DIMMs. However, the amount of memory available to the operating system is less than 8 GB. This is because certain components within the computer require address space in the 8-GB range; and any address space reserved for these components cannot be used by computer memory.
NOTE: 8 GB memory is available only if you ordered an operating system that supports 64 bits. If you ordered a system that supports only 32 bits then the memory available is 4 GB.
Installing Memory
CAUTION: Before you perform any of the procedures in this section, follow the safety instructions 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.
