Memory Installation Guidelines
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. You should install your original memory modules in pairs either in connectors DIMM1 and
DIMM2 or connectors DIMM3 and DIMM4. If possible, do not pair an original memory module with
a new memory module. Otherwise, your computer may not function at optimal performance.
NOTE: Memory purchased from Dell is covered under your computer warranty.
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
CAUTION: Before you begin any of the procedures in this section, follow the
safety instructions on page 9.
1 Shut down the computer through the Start menu (see page 27).
2 Ensure that your computer and attached devices are turned off. If your computer and
attached devices did not automatically turn off when you shut down your computer,
turn them off now.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then
unplug it from the network wall jack.
