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  
Hardware Reference Guide  
www.hp.com  
2-5  
             
Hardware Upgrades  
The following processor bus frequencies are required for the system  
to run at the supported memory frequencies.  
Memory Frequency  
266 MHz  
Required Processor Bus Frequency  
400 MHz, 533 MHz, or 800 MHz  
533 MHz or 800 MHz  
333 MHz  
400 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.

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.

Installing a Drive into the 3.5-inch Drive Bay  
Depending on the computer configuration, the 3.5-inch drive bay on  
the left side of the computer may be configured with a diskette drive  
or it may be an empty drive bay. The type of bezel covering the  
drive bay will vary depending on the original computer configuration.  
If the computer was not configured with the optional diskette drive,  
you can install a 3.5-inch device, such as a diskette drive or hard  
drive, into the drive bay at any time.  
The type of bezel you need will depend on the type of device you plan  
to install. If you are installing a diskette drive, you must install a  
diskette drive bezel (PN 316002-001). If you are installing a hard  
drive, you must install a bezel blank (PN 316006-001). If you are  
installing a 3.5-inch device other than a diskette drive or hard drive,  
you must install the 3.5-inch device bezel (PN 316008-001). Contact  
an authorized HP reseller or service provider to order the appropriate  
bezel when reconfiguring the computer.  
To install a secondary PATA hard drive, you must use a dual-headed  
cable (part number 108950-051).

PATA Hard Drive Installation Guidelines  
Using the Cable-Select Feature with Parallel ATA  
(PATA) Devices  
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.  
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:

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.  
If you have only one device, make sure to connect it to the Device 0  
connector. If you connect it to the Device 1 connector, the system will  
not recognize the device and you may receive a “no fixed disk found”  
error message.

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  
F-1
