Some special features---
CPU Thermal Throttling/ CPU Vcore 7-shift )
in this motherboard
are designed for power user to use the over-clocking function in more flexible ways. But
please be caution that the over-clocking may cause the fails in system reliabilities. This
motherboard provides the guaranteed performance and meets the demands of the next
generation computing. But if you insist to gain more system performance with variety
possibilities of the components you choose, please be careful and make sure to read the
detailed descriptions of these value added product features, please get them in the coming
section.
1-1.1 Special Features of Motherboard
CPU Thermal Throttling Technology---(The CPU Overheat Protection Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40
℃ to 90℃). When the system senses the CPU operating temperature reaching the preset
value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool
down the processor. When at throttling mode the beeper sound can be optionally selected to
indicate it is in working.
CPU Smart Fan---( The Noise Management System )
It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.
CPU Smart Fan Noise Management System is the answer to control the noise level needed for
now-a-day’s high performance computing system. The system will automatically increase the
fan speed when CPU operating loading is high, after the CPU is in normal operating condition,
the system will low down the fan speed for the silent operating environment. The system can
provide the much longer life cycle for both CPU and the system fans for game use and
business requirements.
CPU Vcore 7-Shift--- (Shift to Higher Performance)
The CPU voltage can be adjusted up by 7 steps for the precisely over-clocking of extra
demanding computing performance.

Hardware Installation
2-1 Install Socket AM2 Supported AMD Processor
This motherboard provides a 940-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA940 socket supports AMD Athlon64 processor in the 940 Pin package
utilizes Flip-Chip Pin Grid Array package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.

When you put the CPU into the ZIF socket, No force require to insert of the CPU, then press
the level to Locate position slightly without any extra force.
2-2 Install Memory

Connectors, Headers & Jumpers Setting
3-1 Connectors
(1) Power Connector (24-pin block) : ATXPWR1
ATX Power Supply connector:
This is a new defined 24-pins
connector that usually comes with
ROW1 ROW2
ATX case. The ATX Power Supply
allows using soft power on
momentary switch that connect from
the front panel switch to 2-pins
Power On jumper pole on the
motherboard. When the power
switch on the back of the ATX
power supply turned on, the full
power will not come into the system
board until the front panel switch is
momentarily pressed. Press this
Pin 1
20-Pin
switch again will turn off the power to the system board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin
power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15A on +12V and the power supply unit has a minimum
power rating of 350W. The system may become unstable or may not boot up if the
power is inadequate.

USEFUL HELP
4-1 HOW TO UPDATE BIOS
Before updating the BIOS, users have to “Disable” the “Flash Part Write Protect” selection in
“Miscellaneous Control” of BIOS SETUP. Otherwise the system the will not allow you to upgrade
BIOS by Award Flash Utility.
STEP 1. Prepare a boot disc. (you may make one by click START click RUN type SYS A:click OK)
STEP 2. Copy utility program to your boot disc. You may copy from DRIVER CD
X:\FLASH\AWDFLASH.EXE or download from our web site.
STEP 3. Download and make a copy of the latest BIOS for VIA K8M800 PPC motherboard series
from the web site to your boot disc.
STEP 4. Insert your boot disc into A:,
start the computer, type “Awdflash A:\ VIA K8M800.BIN /SN/PY/CC/R”
VIA K8M800Y xxx.BIN is the file name of latest BIOS it can be VIA K8M800X.BIN or
VIA K8M800.BIN
SN means don’t save existing BIOS data
PY means renew existing BIOS data
CC means clear existing CMOS data
R means restart computer
STEP 5. Push ENTER to update and flash the BIOS, then the system will restart automatically.
4-2 Trouble Shooting
Problem Solution
No power to the system to the all power light
don’t illuminate, fan inside power supply doesn’t
turn on.
System inoperative. Keyboard lights are on ,
power indicator lights are lit, and hard drive is
spinning.
System doesn’t boot from hard disk drive, can be
booted from optical drive.
System only boots from optical drive .Hard disk
can be read and applications can be used but
booting from hard disk is impossible.
Screen message says “Invalid Configuration” or
“CMOS Failure”
Can not boot system after installing second hard
drive.
1. Make sure power cable is security plugged in.
2. Replace cable. 3. Contact technical support.
Using ever pressure on both ends of the DIMM ,
press down firmly until the module snaps into
places.
1. Check cable running from disk to disk
controller board. .Make sure both ends are
securely plugged in, check the drive type in the
standard CMOS setup. 2. Backing up the hard
drive is extremely important .All hard disks are
capable of breaking down at any time.
1. Back up date and applications files. 2.
Reformat the hard drive. Reinstall applications
and date using backup disks.
Review system ‘s equipment .Make sure correct
information on is in setup.
1. Set master /slave jumpers correctly. 2. Run
SETUP program and select correct drive types.
Call the drive manufacture for compatibility with
other drives.
