Removing, Replacing and Upgrading
Memory in HP Kayak XM600 Models
IMPORTANT NOTE This text was updated in December 2000 and replaces all earlier
information on memory replacement in the HP Kayak XM 00.
Replacing SDRAM
SDRAM was available on some XM 00 models shipped before May 2000.
Following an announcement made by the Intel Corporation that SDRAM
memory should not be used with the Intel 820 chipset (the chipset used in
the Kayak XM 00) HP is replacing all SDRAM memory 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 XM 00 carry a
Memory Expansion Card supporting one or two Synchronized Dynamic
RAM (SDRAM) 100 MHz memory modules .
If a memory Expansion Card is installed, as shown below, then the PC
contains SDRAM memory.
To carry out the conversion, you should contact HP Support. You will then
be able to upgrade with RDRAM memory as described below.
The Memory Expansion Card is installed in a reserved memory socket on
the system board (the third socket, furthest from the processor(s)). The
two remaining memory sockets on the system board, RIMM0 and RIMM1
each contain a continuity module.

Removing the Memory Expansion ard and SDRAM Modules
You cannot upgrade with RDRAM memory until the Memory Expansion
Card and all SDRAM memory has been removed.
1Switch off the display and PC Workstation. Disconnect all power cables
and any LAN or telecommunications cables.
2Remove the PC Workstation’s cover (refer to the User Guide for detailed
instructions).
3Remove the HP UltraFlow Airflow Guide to obtain access to the SDRAM
modules and sockets on the memory expansion card.
4Release the retaining screw located on the Memory Expansion Card.
Then remove the screw from the accessory card socket.
5Open the two retaining clips on the system board to release the Memory
Expansion Card, then remove it from the connector.
6Remove the memory modules from the old Memory Expansion Card. To
remove a memory module, open the two retaining clips and lift the
module out of the socket.
7Install the replacement RDRAM module(s) with the necessary
Continuity and Terminator modules in the correct memory slots on the
mother board, as described in the following section see “Upgrading
RDRAM Memory”.

Upgrading RDRAM Memory
RDRAM models of the HP Kayak XM 00 PC Workstation support one or
two RAMBUS Direct RAM (RDRAM) memory modules
NOTE Use only the HP memory modules provided for your PC model. If you want
to find out about available accessories for your PC, refer to the HP
Accessories Web site at: http://www.hp.com/go/pcaccessories

•ECC and non-ECC modules can be mixed, but if this is done, all memory
will operate in non-ECC mode
•the socket RIMM2 must contain an RDRAM Terminator Module.

Removing and Replacing an RDRAM Module
1Switch off the display and PC Workstation. Disconnect all power cables
and any LAN or telecommunications cables.
2Remove the PC Workstation’s cover (refer to the User Guide for detailed
instructions).
3Remove the HP UltraFlow Airflow Guide.
4To remove a memory module, open the two retaining clips and lift the
module out of the socket.
5To install a module, check that the two notches of the memory module
are aligned with the two locating stubs in the socket (these ensure the
module cannot be inserted in the reverse alignment). With the two
retaining clips open, press the memory module completely into the
socket. You hear two clicks as 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.
8Power up the PC and check the HP Summary Screen to verify the new
configuration.
