lPlug the computer into a working electrical outlet (see Power Lights)
A possible processor failure has
occurred.
Reinstall the processor (see Installing the Processor) and restart the computer.

Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies
a problem. For example, beep code 1-3-1 consists of one beep, a burst of three beeps, and then one beep.This beep code tells you that the computer
encountered a memory problem.
Reseating the memory modules (see Installing Memory) may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in
your Owner's Manual for instructions on obtaining technical assistance.
The following table lists beep codes for non memory related errors.
Memory modules are detected, but a
memory failure has occurred.
lIf two or more memory modules are installed, remove the modules (see Removing
Memory), then reinstall one module (see Installing Memory) and restart the computer. If the
computer starts normally, continue to install additional modules (one at a time) until you
have identified a faulty module or reinstalled all modules without error.
lIf available, install properly working memory of the same type into your computer (see
Installing Memory).
A possible graphics card failure has
occurred.
lReseat any installed graphics card (see Installing a PCI Express Card).
lIf available, install a working graphics card into your computer.
A possible floppy drive or hard drive
failure has occurred.

A possible USB failure has occurred.
Reinstall all USB devices and check all cable connections.
No memory modules are detected.
lIf two or more memory modules are installed, remove the modules (see Removing
Memory), then reinstall one module (see Installing Memory) and restart the computer. If the
computer starts normally, continue to install additional modules (one at a time) until you
have identified a faulty module or reinstalled all modules without error.
lIf available, install properly working memory of the same type into your computer (see
Installing Memory).
Memory modules are detected, but a
memory configuration or compatibility
error has occurred.
lEnsure that no special requirements for memory module/connector placement exist (see
Memory).
lEnsure that the memory you are using is supported by your computer (see Memory).
A possible expansion card failure has
occurred.
1. Determine if a conflict exists by removing a card (not a graphics card) and restarting the
computer (see Cards).
2. If the problem persists, reinstall the card that you removed, then remove a different card
and restart the computer.
3. Repeat this process for each card installed. If the computer starts normally, troubleshoot
the last card removed from the computer for resource conflicts (see Resolving Software and
Hardware Incompatibilities).
The system is operating in quick
resume mode.

Memory
You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your
computer, see Memory.

Memory Overview
lMemory modules should be installed in pairs of matched memory size, speed, and technology for best performance. Otherwise, the computer will continue
to operate, but with a slight reduction in performance. See the label on the module to determine the module's capacity.
The recommended memory configurations are:
1
memory module
connectors (1, 2, 3, 4)

lIf you install mixed pairs of DDR2 533-MHz (PC2-4300), DDR2 667-MHz (PC2-5300), and DDR2 800-MHz (PC2-6400) memory, the modules function at the
slowest speed installed.
l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.
lWhile installing memory modules, ensure that you do not mix ECC and non-ECC memory.

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. Remove the computer cover (see Removing the Computer Cover).

3. Lay the computer on its side so that the system board is on the bottom of the inside of the computer.
