• Auto Fan Off: The system fans will power off automatically even in standby
mode. This function reduces both energy consumption and system noise, and is
an important feature in implementing silent PC systems.
• Dual Function Power Button: Pushing the power button for less than 4 sec-
onds when the system is in the working state places the system into one of two
states: sleep mode or soft-off mode, depending on the BIOS or OS setting. When
the power button is pressed for more than 4 seconds, the system enters the soft-
off mode regardless of the BIOS setting.

WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
nothave one, touch bothof your hands toa safely grounded objector to a metal
object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or con-
nectors, or other components.
4. Placecomponents ona groundedantistatic pad or on the bag thatcame withthe
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
powered OFF.

2.5.1 General DIMM Notes
•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
•SDRAM chips are generally thinner with higher pin density than EDO (Extended
Data Output) chips.
•Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.
2.5 System Memory (DIMM)
NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are
available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB.
This chipset does not support ECC. However, ECC memory modules may still be
used, but the ECC function will not be available.

2.5.2 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. DIMM mod-
ules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMMs have the same pin contact on both sides.

The notches on the DIMM 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 purchasing.
This motherboard supports four clock signals per DIMM slot.

2.6 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.
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
upwards 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.
CAUTION! Be careful not to scrape the motherboard when mounting a clamp-
style processor fan or else damage may occur to the motherboard.
