CAUTION!
1. 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.
2. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
3. Power Management for USB 2.0 works fine under Microsoft®Windows®
XP SP1/2000 SP4. It may not work properly under Microsoft®Windows®
98/ME. Please refer to Microsoft®official document at
http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx
4. 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. The CPU host frequency of this motherboard is determined by the
jumper-setting. You must set the FSB jumper according to yourAMD CPU
before you use the “Manual” option as the FSB setting in BIOS setup to
perform over clocking. Please check page 22 for details.

2. Installation
K7VT4A+ is an ATX form factor (12.0-in x 7.0-in, 30.5 cm x 17.8 cm) motherboard.
Before you install the motherboard, study the configuration of your chassis to en-
sure that the motherboard fits into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
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.
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.
5. When placing screws into the screw holes to secure the motherboard
to the chassis, please do not over-tighten the screws! Doing so may
damage the motherboard.

2.1 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90oangle.
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
AMDAthlonTM /AthlonTM XP/DuronTM family CPUs with a speed of 600 MHz and
higher require larger heatsink and cooling fan. Thermal grease between the
CPU and the heatsink is also needed to improve heat transfer. 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_FANconnector (CPU_FAN1,
see page 7, No. 2). For proper installation, please kindly refer to the instruc-
tion manuals of the CPU fan and heatsink vendors.
