2. Installation

K7VT6-C 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 ensure 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.

3. 4. 5.

Unplug the power cord from the wall socket before touching any component. 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. Hold components by the edges and do not touch the ICs. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component. 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.

Step 1. Step 2. Step 3.

CPU Installation
Unlock the socket by lifting the lever up to a 90 angle. Position the CPU directly above the socket such that its marked corner matches the base of the socket lever. 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.

Step 1

Step 2, 3

Step 4

Installation of CPU Fan and Heatsink
AMD AthlonTM / 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 FAN connector (CPU_FAN1, see page 7, No. 2). For proper installation, please kindly refer to the instruction manuals of the CPU fan and heatsink vendors.
Installation of Memory Modules (DIMM)
K7VT6-C motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots.
Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Step 2.

Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot.

notch break

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 the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
Expansion Slots (PCI and AGP Slots)
There are 5 PCI slots and 1 AGP slot on K7VT6-C motherboard. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. AGP slot: The AGP slot is used to install a graphics card. The ASRock AGP slot has a special design of clasp that can securely fasten the inserted graphics card.
Please do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! For the voltage information of your graphics card, please check with the graphics card vendors.
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. Remove the system unit cover (if your motherboard is already installed in a chassis). Remove the bracket facing the slot that you intend to use. Keep the screws for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws. Replace the system cover.

2. Installation
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. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components. 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. Hold components by the edges and do not touch the ICs. Whenever you uninstall any component, place it on a grounded antstatic pad or in the bag that comes with the component. 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.

Step 1. Step 2. Step 3.

CPU Installation
Unlock the socket by lifting the lever up to a 90 angle. Position the CPU directly above the socket such that its marked corner matches the base of the socket lever. 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.

Step 5.
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. Install CPU fan and heatsink. For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink vendors.
Installation of Memory Modules (DIMM)
K7VT6-C motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots.
Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Step 2.

Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM 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 the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
2.3 Expansion Slots (PCI and AGP Slots)
There are 5 PCI slots and 1 AGP slot on K7VT6-C motherboard. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. AGP slot: The AGP slot is used to install a graphics card. The ASRock AGP slot has a special design of clasp that can securely fasten the inserted graphics card.
Please do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! For the voltage information of your graphics card, please check with the graphics card vendors.
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. Remove the bracket facing the slot that you intend to use. Keep the screw for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws.

Step 2. Step 3. Step 4.

2.4 Jumpers Setup
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 the 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. Jumper

FSB Select Jumpers

(FSB_SEL0, FSB_SEL1, FSB_SEL2) (see p.2 item 10)
Note: The CPU FSB frequency of this motherboard is determined by jumper-setting. You must adjust FSB Select Jumpers according to the FSB of your AMD CPU. Please follow the figures above to set the CPU FSB frequency.

Setting

PS2_USB_PWR1

(see p.2 item 1)
