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 8GB
(1-Gbit Technology) of memory configured in a high-performing
dual channel mode.
Hardware Upgrades
✎
The memory available may be limited by the operating system.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM
DIMMs, the DIMMs must be:
■ industry-standard 184-pin
■ unbuffered PC3200 400 MHz-compliant
■ 2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■ support CAS latency 3 (CL = 3)
■ contain the mandatory JEDEC SPD information
In addition, the computer supports:
■ 128Mbit, 256Mbit, 512Mbit, and 1Gbit non-ECC memory
technologies
■ single-sided and double-sided DIMMS
■ DIMMs constructed with x8 and x16 DDR devices; DIMMs
The system will not start if you install unsupported DIMMs.
✎
Hardware Reference Guide www.hp.com 2-5
constructed with x4 SDRAM are not supported
Hardware Upgrades
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, always populate the XMM1 socket first.
If you add a second DIMM of a different memory size than the
first, install it in XMM3. Otherwise, the system will not operate.
✎
In single channel mode, the maximum operational speed is
determined by the slowest DIMM in the system. 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. If
you are populating only two DIMM sockets, you must use
identical DIMMs and populate them in XMM1 and XMM2, the
black sockets. If you are populating all four DIMM sockets, you
must either use identical DIMMs in all sockets or use identical
DIMM pairs in each pair of sockets, XMM1 and XMM2 black
sockets and XMM3 and XMM4 blue sockets. Otherwise, the
system may not operate properly.
2-6 www.hp.com Hardware Reference Guide
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 XMM3 operate in memory channel A.
Sockets XMM2 and XMM4 operate in memory channel B.

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.
D
■ 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.
Hardware Reference Guide www.hp.com D-1
Electrostatic Discharge
✎
■ 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.

Computer Operating Guidelines and Routine Care
CAUTION: If the computer is in the desktop configuration, ensure at
Ä
least 4 inches (10.2 cm) of space on all sides of the computer remains
clear and free of obstructions.
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. For information about
the recommended temperature and humidity ranges for the
computer, refer to Appendix A, “Specifications” in this guide.
■ 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 cover or side panel
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,
