computers can cause incorrect computer responses or result in error messages.
The Dell Diagnostics allow you to:
• Perform quick checks or extensive tests on one or all devices.
• Choose how many times a test is run.
• Display or print test results or save them in a file.
• Suspend testing if an error is detected or terminate testing if a certain number of errors occur.
• Access online
Help
screens that describe the tests and how to run them.
• Read status messages that tell you whether tests completed successfully.
• Receive error messages if problems are detected.
Before You Start Testing
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide.
• Turn on your printer if one is attached.
• Enter system setup, review your computer’s configuration information, and then enable all of
your computer’s components and devices, such as connectors.

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. One possible beep code
(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.
If your computer beeps during start-up:
1
Write down the beep code on the Diagnostic Checklist (see your
User’s Guide
).

Memory Overview
NOTE: Your computer supports ECC and registered memory.
• Memory modules should be installed in
pairs of matched size, speed, and rank (1R is single
rank and 2R is dual rank)
. See the label on the memory module to determine its size, speed
rank, and organization. Be sure that your memory module labels match.
Example: 256MB 1Rx8 PC2-3200R-333-10:
• Size = 256 MB
• Speed = 3200
• Rank = 1R
• Organization = x8
256MB 2R XX XXX
36 Quick Reference Guide
• Memory modules can be single rank (1R) or dual rank (2R) and should be installed in the
following order:
• The highest rank memory module in DIMM_1 and DIMM_2
• Equal or lower rank memory modules in DIMM_3 and DIMM_4
• Single rank (1R) memory modules in DIMM_5 and DIMM_6
• If only two memory modules are installed, they must be installed in DIMM_1 and DIMM_2.
These connectors are located on the outside edge of the board.
• Memory modules should be installed in the following order: connectors DIMM_1 and
DIMM_2, DIMM_3 and DIMM_4, and then DIMM_5 and DIMM_6.
If dual-rank modules are installed in DIMM_3 and DIMM_4, then DIMM_5 and DIMM_6
cannot be used.
• Dual-rank memory modules are not supported in DIMM_5 and DIMM_6.
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 in connectors
DIMM_1 and DIMM_2, connectors DIMM_3 and DIMM_4, and then DIMM_5 and DIMM_6.
NOTICE: If you install more than 4 GB of memory, you must also install a fan to cool the computer. If you
do not install a fan, you will get an error message stating that you must install a fan or remove
some memory.
