Revision #: 88 Page: 8 of 50 Printed: 04/25/01 09:02 AM
RIMMs
RIMMs must be 184-pin RDRAM (Rambus
dynamic random access memory), non-ECC
(non-error correction checking), compliant with
the Rambus/Intel specification.
The motherboard has four RIMM sockets that are
for a dual-channel configuration. The following
requirements must be met:
3The HP Pavilion uses PC600 or PC800 RDRAM
modules. Rambus signaling level technology
permits 600 and 800 MHz transfer rates.
3All four RIMM sockets must be filled. If you do
not populate a socket with a RIMM, the empty
socket must be filled with a C-RIMM (continuity
RIMM). Two C-RIMMs are included on the
motherboard.
Note:
A C-RIMM does not contain any memory —it is
only a placeholder card used to close the
memory circuit. C-RIMMs are necessary to
avoid breaking the signal lines, which are a
serial connection in a Rambus interface; this
ensures the electrical integrity.
3RIMMs work in identical pairs, so they must be
from the same vendor, and have the same
speed, and memory size density within each
channel (see the memory table).
3When C-RIMMs are used to fill empty sockets,
they must be placed in the RIMM A2 and
RIMM B2 sockets. The RIMMs must be inserted in
the RIMM A1 and RIMM B1 sockets.

Installing Add-In Cards
At some point, you may add a PCI or AGP card to
the computer to accommodate a new component,
such as a scanner, or to upgrade an existing card.
Warning:
Do not overload the system
by installing add-in cards that draw
excessive current. The system is designed
to provide 2 amps (average) of +5 V
power for each board/card in the
computer. The total +5 V current draw in
a fully loaded system (one with all add-in
card slots filled) must not exceed the total
number of slots multiplied by 2 amps.
Avertissement :
Ne surchargez pas
l’ordinateur en installant des cartes
d’extension qui consomment beaucoup de
courant. L’ordinateur est conçu pour
fournir un courant de 2 ampères (en
moyenne), +5 volts, àchaque carte
installée sur l’ordinateur. La
consommation totale de courant de +5 V
sur un ordinateur entièrement chargé
(dont tous les logements de cartes sont
occupés) ne doit pas excéder le nombre
total de supports multipliépar 2 ampères.
To add or replace an add-in card:
1Turn off the computer and all peripherals.
2Disconnect the modem/phone cable.
3Disconnect the power cord and all other
attached cables (such as the keyboard, mouse,
and monitor).

cables.
3Reconnect the modem/phone cable.
4Turn on the computer and all peripherals.
5Install any software drivers supplied by the
card manufacturer.
What Is Plug and Play?
“Plug and Play”describes the ability to add and
remove add-in cards, memory, and peripherals
without any special procedures such as resetting
jumpers and testing for system conflicts. The
system BIOS (basic input/output system) finds
these components and adds them to the system.
You do not have to run the BIOS setup program.
If the New Card or Device Isn’t
Working
Read through the card manufacturer’s installation
instructions, and recheck all connections,
including those to the card, power supply,
keyboard, and monitor. If the problem still exists,
run the BIOS setup program and load the default
settings, and then save and exit.
