CAUTION!
1. About the setting of “Hyper Threading Technology”, please check page 24.
2. 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 a nd the heatsink when you in stall the PC syste m.
3. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
4. Power Management for USB 2.0 works fine under Microsoft® Windows® XP
SP1 / 2000 SP4. It may not work properly under Microsoft
ME.
5. Although this motherboard offers stepless control, it is not recommended

P4VM800 is a Micro ATX 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 ensure that the motherboard fits into it.
Take note of the following precautions before you install motherboard components 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 antistatic 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.

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.

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 securely fastened and in good contact with each other. Then connect the CPU
fan to the CPU_FAN connector (CPU_FAN1, see p.8 No. 30). For proper
installation, please kindly refer to the instruction manuals of the CPU fan and
the heatsink.
