WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the third-
party overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by
overclocking.

CAUTION!
1. About the setting of “Hyper Threading Technology”, please check page 28.
2. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 24 for details.
3. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
4. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
5. Power Management for USB 2.0 works fine under Microsoft®Windows® XP
SP1 or SP2 / 2000 SP4.

Installation
P4VM890 is a MicroATX form factor (9.6-in x 8.0-in, 24.4 cm x 20.3 cm) motherboard.
Before you install the motherboard, study the configuration of your chassis to en-
sure that the motherboard fits into it.
Pre-installation PrecautionsPre-installation Precautions
Pre-installation PrecautionsPre-installation Precautions
Pre-installation Precautions
Take note of the following precautions before you install motherboard com-
ponents or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded
object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded anti-
static pad or in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched off or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.

2.1 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90° angle.
Step 2. Position the CPU directly above the socket such that its marked corner
matches the base of the socket lever.
Step 3. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the
CPU into the socket to avoid bending of the pins.
Step 4. When the CPU is in place, press it firmly on the socket while you push down
the socket lever to secure the CPU. The lever clicks on the side tab to
indicate that it is locked.

2.2 Installation of CPU Fan and Heatsink
This motherboard adopts 478-pin CPU socket to support Intel®Pentium® 4/
Celeron®CPU. It requires larger heatsink and cooling fan to dissipate heat.
You also need to spray thermal grease between the CPU and the heatsink to
improve heat dissipation. Make sure that the CPU and the heatsink are se-
curely fastened and in good contact with each other. Then connect the CPU
fan to the CPU_FAN connector (CPU_FAN1, see p.9 No. 29). For proper
installation, please kindly refer to the instruction manuals of the CPU fan and
the heatsink.

2.3 Installation of Memory Modules (DIMM)
P4VM890 motherboard provides two 184-pin DDR (DoubleData Rate)DIMM slots.
Please make sure to disconnect power supply before adding or removing
DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause
permanent damage to the motherboard and the DIMM if you
force the DIMM into the slot at incorrect orientation.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.

Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed in a
chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the screws
for later use.
Step 4. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose pin1
and pin2 are “Short” when jumper cap is
placed on these 2 pins.

Note: To select +5VSB, it requires 2 Amp and higher standby current provided
by power supply.

Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on

(see p.9, No. 28) ports by attaching the front panel
USB cable to USB4_5 header,
the USB ports 45 on the I/O panel
will not be able to function.

processed.
2. Even some SATA HDDs provide both SATA 15-pin power connector and IDE
1x4-pin conventional power connector interfaces, the IDE 1x4-pin conventional
power connector interface is definitely not able to support Hot Plug and will
cause the HDD damage and data loss.
