PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s,
MCH dual channel Rambus DRAMs can operate at up to 400 MHz with a peak
bandwidth of 3.2GB/s.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (OSPM) functionality . W ith these features implemented in the OS,
PCs can be ready around the clock, yet satisfy all the energy saving standards.
To fully utilize the benefits of ACPI, an ACPI-supported OS, such as W indows
98/2000/Millenium, must be used.

• Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do
not have to wait for a long time for system bootup.

• New Compliancy: Both the BIOS and hardware levels of the motherboard meet

the stringent requirements for PC 99 certification. The new PC 99 requirements
for systems and components are based on the following high-level goals: sup­port for Plug and Play compatibility and power management for configuring
and managing all system components, and 32-bit device drivers and installation
procedures for Windows 95/NT and later. Color-coded connectors and descrip­tive icons make identification easy as required by PC 99.

2.1.3 Intelligence

• Auto CPU Throttling Function: Incorporated into this motherboard is a new

technology to enable Pentium 4 processors auto throttling function. When auto
throttling is enabled, the CPU with throttle down to 50% of its duty cycle when
the CPU temperature reaches the threshold and return to 100% of its duty cycle
when temperature lowers to normal level. This function ensures the best
performance and reliability.

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU, PCI, and MAIN fans can be monitored for RPM and failure.
All the fans are set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-

age, this motherboard supports processor thermal sensing and auto-protection.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure

stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.

Intelligence

2. FEATURES

• System Resources Alert: Today’s operating systems, such as Windows 98/

Millenium, and W indows NT/2000, require much more memory and hard drive
space to present enormous user interfaces and run large applications. The onboard
hardware ASUS ASIC in conjunction with either the bundled ASUS PC Probe
or Intel LDCM will warn the user before the system resources are used up to
prevent possible application crashes. Suggestions will give the user information
on managing their limited resources more efficiently.

• Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

• Remote Ring On (requires modem): This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on-hand, users
can access any information from their computers from anywhere in the world.

• Message LED (requires ACPI OS support): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine if a message has been received from a fax/modem. A simple glimpse
provides useful information to the user. This function requires ACPI OS and
driver support.

• Peripheral Power Up: Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or con­nectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.

5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.

WARNING! Make sure that you unplug your power supply when adding or

removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components. The onboard LED when
lit acts as a reminder that the system is in suspend or soft-off mode and not

2) USB Device Wake Up (USBPWR)

This allows you to disable or enable the USB device wake up function. Set this
jumper to Enable if you wish to use your USB devices to wake up your computer .
This feature requires an ATX 12V power supply that can supply at least 2A on the
+5VSB lead. The default is set to Disable because not all computers have the
appropriate ATX power supply. Your computer will not power ON if you set this
to Enable and do not have the appropriate ATX power supply.

NOTES

1. This jumper must be set in conjunction with Wake On USB Device in 4.5.1
Power Up Control.

2. To support wake up from USB devices, this jumper must be set to Enable.

3. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in the sleep mode.

3.5 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory .
This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.

These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.

IMPORTANT

1. The memory configuration of channel A (RIMMA1 and RIMMA2) and chan­nel B (RIMMB1 and RIMMB2) must be identical (see below).

2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are
not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the
signal lines, which are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.

3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.

Step 1: Install the Baseboard

A metal baseboard is required to install the heatsink to the motherboard. A rubber
pad is placed between the metal board and motherboard to provide insulation to
prevent shorting.

Align the rubber pad over
the metal baseboard so that
the holes match. Align the
motherboard over the rub­ber pad and metal base­board so that the screws on
the baseboard match up
with the motherboard’s
screw holes.

Rubber Pad Metal Baseboard

Place the four washers over the four
screws on the baseboard.

IMPORTANT:

This step is a MUST! The washers
are necessary to prevent shorting.

Tighten the four copper captive
nuts over the washers.

Step 2: Install the CPU

A. Locate the ZIF socket on the motherboard.
B. Unlock the socket by pressing the lever sidesways and then lifting it up to a

90˚–100˚ angle.

C. Align the CPU over the socket such that its notched or marked corner matches

the socket’ s corner near the end of the lever, while making sure that the CPU is
parallel to the socket.

D. Carefully insert the CPU into the socket until it fits in place. The illustration

below shows how to insert a CPU properly.

CAUTION! The CPU fits in only one orientation. Do not force the CPU into the

socket as it will bend the pins and damage the CPU. It should drop into the
socket with minimal pressure. If not, check its orientation or check for bent pins.

E. Secure the CPU into the socket by pushing the socket lever all the way down.

You will hear a click indicating that the lever is in place.

WARNING! Be sure that there is sufficient air circulation across the processor’ s

heatsink by regularly checking that your CPU fan is working. W ithout sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket 423 pro­cessor or else boot-up may not be possible. Socket 423 processors provide internal
thermal sensing so that a socket mounted thermal resistor is not needed.
