CAUTION!
1. While CPU overheat is detected, the system will automatically shut-
down. Please check if the CPU fan on the motherboard functions
properly before you resume the system. To improve heat dissipation,
remember to spray thermal grease between the CPU and the heatsink
when you install the PC system.
2. Do NOT insert a 3.3V AGP card into the AGP slot of K7VT4-4X
or K7VT4-8X motherboard! It may cause permanent damage!
3. Power Management for USB 2.0 works fine under Microsoft®
Windows®XP. It may not work properly under Microsoft®Windows®
98/ME/2000. Please refer to Microsoft®official document at
http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx
4. Although K7VT4-4X / K7VT4-8X offers stepless control, it is not
recommended to perform over clocking. When the CPU frequency of
K7VT4-4X / K7VT4-8X is set to perform over clocking, other clocks,
such as PCI clock, AGP clock, and Memory clock will also be
overclocked proportionally. Frequencies other than the recommended
CPU bus frequencies may cause the instability of the system or
damage the CPU.

Chapter 2 Installation
K7VT4-4X / K7VT4-8X is an ATX form factor (12.0" x 7.0", 30.5 x 17.8 cm)
motherboard. Before you install the motherboard, please study the configuration of
your chassis to ensure that themotherboard fits into it.
Make sure to unplug the power cord before installing or re-
moving the motherboard. Failure to do so may cause physical
injuries to you and damages to motherboard components.
2.1 Screw Holes
Please place screws into the holes indicated by circles to secure the motherboard to
the chassis.
Do not over-tighten the screws! Doing so may damage the
motherboard.
2.2 Pre-installation Precautions
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, please place it on a grounded antistatic
pad or in the bag that comes with the component.
Before you install or remove any component, pleasse 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.
