Serviceability Features
The Microtower computer includes features that make it easy to
upgrade and service. No tools are needed for most of the installation
procedures described in this chapter.
Warnings and Cautions
Before performing upgrades be sure to carefully read all of the
applicable instructions, cautions, and warnings in this guide.
ÅWARNING: To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet and allow the internal system components to cool before touching.
ÅWARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications/telephone connectors into the
network interface controller (NIC) receptacles.
ÄCAUTION: Static electricity can damage the electrical components of the
computer or optional equipment. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See Appendix F, “Electrostatic Discharge” for
more information.
ÄCAUTION: Before removing the computer cover, ensure that the
computer is turned off and that the power cord is disconnected from the
electrical outlet.

Removing the Computer Access Panel and
Front Bezel
To remove the computer access panel:
1. If you have locked the Smart Cover Lock, use Computer Setup to
unlock the lock. Refer to the Desktop Management Guide on the
Documentation Library CD for more information about the Smart
Cover Lock.
✎If you enable the Smart Cover Lock and cannot disable the lock
through Computer Setup, you will need a Smart Cover FailSafe Key
to remove the screws that retain the lock and open the computer
cover. Contact an authorized HP reseller or service provider and order
PN 166527-001 for the wrench-style key or PN 166527-002 for the
screwdriver bit key.
2. Turn off the computer properly through the operating system and
turn off any external devices.
3. Disconnect the power cord from the power outlet 1and the
computer 2, and disconnect any external devices.

Installing Additional Memory
The computer comes with double data rate synchronous dynamic
random access memory (DDR-SDRAM) dual inline memory
modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to
four industry-standard DIMMs. These memory sockets are populated
with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 4GB
of memory configured in a high-performing dual channel mode.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM
DIMMs, the DIMMs must be:
■industry-standard 184-pin
■unbuffered PC2100 266 MHz-, PC2700 333 MHz-, or PC3200
400 MHz-compliant
■2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■support CAS latency 2 or 2.5 (CL = 2 or CL = 2.5)
■contain the mandatory JEDEC SPD information
In addition, the computer supports:
■128Mbit, 256Mbit, and 512Mbit non-ECC memory technologies
■single-sided and double-sided DIMMS
■DIMMs constructed with x8 and x16 DDR devices; DIMMs
constructed with x4 SDRAM are not supported
The following processor bus frequencies are required for the system
to run at the supported memory frequencies.

2–6 www.hp.com Hardware Reference Guide
Hardware Upgrades
If a memory frequency is paired with an unsupported processor bus
frequency, the system will run at the highest supported memory
speed. For example, if a 333 MHz DIMM is paired with a 400 MHz
processor bus, the system will run at 266 MHz, the highest supported
memory speed.
✎The system will not start if you install unsupported DIMMs.
DIMM Sockets
The system will automatically operate in single channel mode or a
higher-performing dual channel mode, depending on how the DIMMs
are installed.
■In single channel mode, the maximum operational speed is
determined by the slowest DIMM in the system. For example, if
the system is populated with a DIMM that is 266 MHz and a
second DIMM that is 333 MHz, the system will run at the slower
of the two speeds.
■In dual channel mode, all DIMMs must be identically matched.
DIMMs in the XMM1 and XMM3 black sockets must be
identical; DIMMs in the XMM2 and XMM4 blue sockets must
also be identical. Therefore, if you have one preinstalled DIMM
in socket XMM1 and are adding a second DIMM, it is
recommended that you install an identical DIMM into the XMM3
socket. If you are populating all four DIMM sockets, use identical
DIMMs in each socket. Otherwise, the system will not operate in
dual channel mode.
Memory Frequency Required Processor Bus Frequency
266 MHz 400 MHz, 533 MHz, or 800 MHz
333 MHz 533 MHz or 800 MHz
400 MHz 800 MHz

Hardware Reference Guide www.hp.com 2–7
Hardware Upgrades
There are four DIMM sockets on the system board, with two sockets
per channel. The sockets are labeled XMM1, XMM2, XMM3, and
XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.
DIMM Socket Locations

Hardware Upgrades
Installing DDR-SDRAM DIMMs
ÄCAUTION: The memory module sockets have gold metal contacts. When
upgrading the memory, it is important to use memory modules with gold
metal contacts to prevent corrosion and/or oxidation resulting from having
incompatible metals in contact with each other.
ÄCAUTION: Static electricity can damage the electronic components of
the computer or optional cards. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more informations, refer to Appendix F,
“Electrostatic Discharge”.
ÄCAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
1. If you have locked the Smart Cover Lock, use Computer Setup to
unlock the lock.
2. Turn off the computer properly through the operating system and
turn off any external devices. Disconnect the power cord from the
power outlet.
3. Remove the access panel and locate the memory module sockets.
ÅWARNING: To reduce risk of personal injury from hot surfaces, allow
the internal system components to cool before touching.
4. Open both latches of the memory module socket 1, and insert the
memory module into the socket 2.
✎If you have one preinstalled DIMM in socket XMM1 and are adding a
second DIMM, it is recommended that you install an identical DIMM
into the XMM3 socket. If you are populating all four DIMM sockets,
use identical DIMMs in each socket. Otherwise, the system will not
operate in dual channel mode.

Hardware Reference Guide www.hp.com 2–9
Hardware Upgrades
Installing a DIMM
✎A memory module can be installed in only one way. Match the notch
on the module with the tab on the memory socket.
5. Push the module down into the socket, ensuring that the module
is fully inserted and properly seated. Make sure the latches are in
the closed position 3.
6. Repeat steps 4 and 5 to install any additional modules.
7. Replace the access panel.
8. If you normally lock the Smart Cover Lock, use Computer Setup
to relock the lock and enable the Smart Cover Sensor.
The computer should automatically recognize the additional memory
the next time you turn on the computer.

Replacing or Upgrading a Drive
The computer supports up to six drives that may be installed in
various configurations.
This section describes the procedure for replacing or upgrading the
storage drives. A Torx screwdriver is needed to replace the guide
screws on a drive.
ÄCAUTION: Make sure you back up your personal files on the hard drive
to an external storage device, such as a CD, before removing the hard
drive. Failure to do so will result in data loss. After replacing the primary
hard drive, you will need to run the Restore Plus! CD to load the HP
factory-installed files.
