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

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.
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.

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.

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
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.
■

■
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.
