Removing, Replacing and Upgrading

Memory in HP Kayak XU800 Models

IMPORTANT NOTE This text was updated in December 2000 and replaces all earlier

information on memory replacement in the HP Kayak XU 00.

Replacing SDRAM

SDRAM was available on some XU 00 models shipped before May 2000.

Following an announcement made by the Intel Corporation that SDRAM

memory should not be used with the Intel 40 chipset (the chipset used in

the Kayak XU 00) HP is replacing all SDRAM memory already shipped with

RDRAM (RAMBUS DRAM) memory.

To determine whether you have SDRAM or RDRAM memory installed,

remove the cover of the PC. SDRAM models of the HP Kayak XU 00 carry a

SDRAM Memory Expansion Card as shown below.

To carry out the conversion, you should contact HP Support. You will then

be able to upgrade with RDRAM memory as described here.

Replacing and Upgrading RDRAM Memory

There is a single Memory Expansion Card connector on the system board

for an RDRAM Memory Expansion Card.

NOTE Do not

install a memory module directly into the connector for the

Memory Expansion Card on the system board.

The RDRAM Memory Expansion Card supports 2 or 4 RDRAM Memory

Modules.

Note the following constraints:

•RDRAM modules must be installed in pairs. The first two sockets A0 and

B0, closest to the system board, contain the first pair of modules.

Upgrades are then installed in sockets A1 and B1.

•Pairs must be of identical modules. For instance if A0 contains a 256MB

PC 00 ECC RDRAM then B0 must contain a 256MB PC 00 ECC

RDRAM. For this reason, all HP memory accessories for the XM 00

contain 2 identical modules.

•If sockets A1 and B1 are not used, an RDRAM Continuity Module must

be installed in both sockets.

fan and speaker assembly, and that the two notches on the Memory

Expansion Card are aligned with those of the Memory Card Connector

and accessory card panel.

3With the two retaining clips open, press the Memory Expansion Card

retaining clips click into position. Secure the Memory Expansion Card in

place with the two retaining screws.

4Replace the retaining bar and secure it in place with the screw.

6Replace the HP Ultraflow Airflow Guide (for full instructions see page 25

of the User’s Guide).

7Replace the PC workstation’s cover. Reconnect the power and

telecommunications cables.

Removing and Replacing a Memory Module

NOTE Use only the HP memory modules provided for your PC model. The use of

memory modules from any previous PC computers is not supported. If you

want to find out about available accessories for your PC, refer to the HP

and any LAN telecommunications cables.

2Remove the PC workstation’s cover.

3Remove the HP Ultraflow Airflow Guide (for full instructions, refer to

page 25 of the User’s Guide).

NOTE For PC Workstations with an onboard RIMM, place the PC on its side with

the system board facing upwards for ease of installation..

For PC Workstations with a Memory Expansion Card, install memory

modules directly onto the card without removing it from the system board.

4If you intend to:

aInstall a Memory Module:

For RIMM modules, unused memory sockets contain a continuity

module. Open the two retaining clips and remove the continuity

module from the socket. Store it for future use.

bReplace a Memory Module:

Open the two retaining clips and remove the old memory module.

5Ensure the two notches of the Memory Module are aligned with those of

the socket. With the two retaining clips open, press the memory module

completely into the socket until the retaining clips click into position.

6Replace the HP Ultraflow Airflow Guide.

7Replace the PC Workstation’s cover. Reconnect all the power and

telecommunications cables.
