Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
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 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.
18 Chapter 2 Hardware Upgrades ENWW
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel
A. Sockets DIMM3 and DIMM4 operate in memory channel B.
Figure 2-10 DIMM Socket Locations

Black
White
White
4 DIMM4 socket, Channel B White
NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system will display a POST error message indicating that a memory module must be installed in the black 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 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 Additional Memory 19
Installing DIMMs
CAUTION: You must disconnect the power cord 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.
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 55 .

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.

E Computer Operating Guidelines,
Routine Care and Shipping Preparation
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.
56 Appendix E Computer Operating Guidelines, Routine Care and Shipping Preparation ENWW
