Hardware Upgrades

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.

Hardware Reference Guide www.hp.com

2–5

Hardware Upgrades

Memory Frequency Required Processor Bus Frequency

266 MHz 400 MHz, 533 MHz, or 800 MHz

333 MHz

400 MHz

533 MHz or 800 MHz

800 MHz

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.

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 XMM2 operate in memory channel A.

Sockets XMM3 and XMM4 operate in memory channel B.

Ä

CAUTION: 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.

Ä

CAUTION: 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” .

Ä

CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

1. Turn off the computer properly through the operating system and turn off any external devices. Disconnect the power cord from the power outlet.

2. Remove the access panel and locate the memory module sockets.

Å

WARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

2–8 www.hp.com

Hardware Reference Guide

Hardware Upgrades

3. 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. Otherwise, the system will not operate in dual channel mode.

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.

4. 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.

5. Repeat steps 4 and 5 to install any additional modules.

6. Replace the access panel.

The computer should automatically recognize the additional memory the next time you turn on the computer.

PATA Hard Drive Installation Guidelines

Using the Cable-Select Feature with Parallel ATA

(PATA) Devices

Optional drives are available from HP in kits that include a special drive cable. The configuration of the drive employs a cable-select feature that identifies the drive as device 0 (primary drive) or device 1

(secondary drive).

Device 1 is the drive connected to the cable’s middle connector.

Device 0 is the drive connected to the cable’s end connector (applies

only to 80-conductor ATA cables). See “Guidelines for Installing

PATA Drives” in this appendix for an example of an PATA cable.

HP hard drives ship with jumpers preset to cable-select mode; therefore, no jumper setting changes on the existing or optional drives are required. If you purchase a third-party hard drive, refer to the documentation included with the kit to ensure proper installation and configuration of cables.

If installing a second device on the primary controller, you must use an 80-conductor PATA cable for optimal performance. This cable is standard on select models.

B–1 Hardware Reference Guide www.hp.com

PATA Hard Drive Installation Guidelines

Guidelines for Installing PATA Drives

When installing additional drives, follow these guidelines:

If using multiple devices, HP recommends that the devices be split between the primary and secondary channels for optimum performance. Use an additional cable to connect the additional device to the system board.

80-conductor PATA cable:

18 inches maximum total length, 80-conductor cable with maximum spacing of 6 inches between Device 0 and

Device 1.

Device 0 (primary drive) connector

2

Device 1 (secondary drive) connector

3

System board connector

For optimal performance, connect hard drives to the primary controller. Connect expansion devices, such as ATA optical drives and tape drives, to the secondary controller.

Install either a third-height or a half-height drive into a half-height bay.

Install guide screws to ensure that the drive lines up correctly in the drive cage. Hard drives use 6-32 standard guide screws. Four extra guide screws are installed on the hard drive bracket under the access panel. HP-supplied standard screws are silver.

If only one device is connected to a cable, that device must be attached to the end (Device 0) connector.

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.

Hardware Reference Guide www.hp.com
