Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) 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 8 GB of memory configured in a highperforming dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512Mbit and 1Gbit 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
NOTE: The system will not operate properly if you install unsupported DIMMs.
14 Chapter 2 Hardware Upgrades ENWW
Page 21
Populating DIMM Sockets
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.
Figure 2-5 DIMM Socket Locations
Table 2-1 DIMM Socket Locations
Item Description Socket Color
1 DIMM socket XMM1, Channel A
(populate first)
Black
2 DIMM socket XMM2, Channel A White
3 DIMM socket XMM3, Channel B
(populate second)
Black
4 DIMM socket XMM4, Channel B White
NOTE: A DIMM must occupy the XMM1 socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
ENWW Installing Additional Memory 15
Page 22
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1GB DIMM, and three 512MB DIMMs, Channel
A should be populated with the 1GB DIMM and one 512MB DIMM, and Channel B should be
populated with the two 512MB DIMMs. With this configuration, 2GB will run as dual channel and
512MB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to
drain before adding or removing memory modules. Regardless of the power-on state, voltage is always
supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding
or removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board. If you see an LED light on the system board, voltage is still present.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
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 information, refer to Appendix D,
Electrostatic Discharge
on page 51.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as diskettes or compact discs, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
4. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the
power to drain before adding or removing memory modules. Regardless of the power-on state,
voltage is always supplied to the memory modules as long as the computer is plugged into an
active AC outlet. Adding or removing memory modules while voltage is present may cause
irreparable damage to the memory modules or system board. If you see an LED light on the system
board, voltage is still present.
5. Remove the computer access panel.
6. Locate the memory module sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
16 Chapter 2 Hardware Upgrades ENWW

7. Open both latches of the memory module socket (1), and insert the memory module into the socket
(2).
Figure 2-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
A DIMM must occupy the black XMM1 socket.
For maximum performance, populate the sockets so that the memory capacity is spread as equally
as possible between Channel A and Channel B. Refer to
Populating DIMM Sockets on page 15
for more information.
8. Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted and
properly seated. The DIMM must be pushed all the way down into the socket and sit evenly in the
socket to avoid memory corruption. Make sure the latches are in the closed position (3).
9. Repeat steps 7 and 8 to install any additional modules.
10. Replace the computer access panel.
11. Reconnect the power cord and any external devices, then turn on the computer. The computer

D Electrostatic Discharge
A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following precautions:
●
Avoid hand contact by transporting and storing products in static-safe containers.
●
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
●
Place parts on a grounded surface before removing them from their containers.
●
Avoid touching pins, leads, or circuitry.
●
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
●
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground
cords. To provide proper ground, wear the strap snug against the skin.
●
Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
●
Use conductive field service tools.
●
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, contact an HP authorized
dealer, reseller, or service provider.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service
provider.

Computer Operating Guidelines and Routine Care
Follow these guidelines to properly set up and care for the computer and monitor:
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.
●
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
Never operate the computer with the access panel or any of the expansion card slot covers
removed.
●
Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.
●
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.
●
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software, including
sleep states.
●
Turn off the computer before you do either of the following:
◦
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products
may discolor or damage the finish.
◦
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other
foreign matter can block the vents and limit the airflow.
ENWW Computer Operating Guidelines and Routine Care 53
