damage, the CPU, power supply, and system fans can be monitored for RPM
and failure. All the fans are set for its normal RPM range and alarm thresholds.
•TemperatureMonitoringandAlert:Topreventsystemoverheatandsystemdam-
age, this motherboard supports processor thermal sensing and auto-protection.
•Voltage Monitoring andAlert: 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.
• System Resources Alert: Today’s server operating systems, such as Windows
NT and Windows 2000, require much more memory and hard drive space to
present enormous user interfaces and run large applications. The onboard hard-
wareASUSASIC in conjunction Intel LDSM will warn the user before the sys-
tem resources are used up to prevent possible application crashes. Suggestions
will give the user information on managing their limited resources more effi-
ciently.
• 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.
• Alert-on-LAN II (requires optional hardware component): Part ofWired for
Management to enable ITstaff to remotely respond to and resolve system trouble
which will decrease down time and lower total cost of ownership. Remote man-
agement response via remote diagnostics and troubleshooting work even when
the operating system has frozen. Remote power down for power management.

IMPORTANT: This motherboard’s chipset only supports 64Mbit, 128Mbit, and
256Mbit “registered” SDRAMs with ECC. This motherboard only operates using
synchronousdatatransferstothememory.Whenyouuseaprocessorwith100MHz
FSB, it will require that the memory supports 100MHz. When you use a proces-
sor with 133MHz FSB, it will require that the memory supports 133MHz or
else bootup may not be possible.

3.5.2 DIMM Installation
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation shown. DIMMs are
longer and have different pin contacts on each side and therefore have a higher pin
density compared to SIMMs.

type, check the notches on the DIMMs (see figure below).
The notches on the DIMM module will shift between left, center, or right to identify
the type and also to prevent the wrong type from being inserted into the DIMM slot
on the motherboard. You must ask your retailer the correct DIMM type before pur-
chasing.

3.6 Central Processing Unit (CPU)
The motherboard provides a ZIF Socket 370. The CPU that came with the mother-
board should have a fan attached to it to prevent overheating. If this is not the case,
then purchase a fan before you turn on your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink by regularly checking that your CPU fan is working. Without sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary. The CPU will be
unstable if the heatsink is not properly mounted. Double check the contact.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then up-
wards to a 90-degree angle. Insert the CPU with the correct orientation as shown. The
notched corner should point towards the end of the lever. Because the CPU has a
corner pin for two of the four corners, the CPU will only fit in the orientation as
shown. The picture is for reference only; you should have a CPU fan that covers the
face of the CPU. With the added weight of the CPU fan, no force is required to insert
the CPU. Once completely inserted, close the socket’s lever while holding down the
CPU. Next, install an Intel recommended fan heatsink. Locate the CPU fan connector
(see 3.1MotherboardLayout or 3.8 Connectors) and connect the CPU fan cable to it.
NOTE: The correct Bus Frequency and Multiple for your Socket 370 processor is
automatically set by this motherboard. Socket 370 processors provide internal ther-
mal sensing so that a socket mounted thermal resistor is not needed.
CAUTION! Be careful not to scrape the motherboard when mounting a clamp-
style processor fan or else damage may occur to the motherboard.
