Central Processing Unit: CPU  
The mainboard supports AMD® DuronTM/AthlonTM processor. The  
mainboard uses a CPU socket called Socket-462 for easy CPU installation.  
When you are installing the CPU, make sure the CPU has a heat sink and a  
cooling fan attached on the top to prevent overheating. If you do not find the  
heat sink and cooling fan, contact your dealer to purchase and install them  
before turning on the computer.  
CPU Installation Procedures  
Open Lever  
1. Pull the lever sideways away  
from the socket. Then, raise  
the lever up to a 90-degree  
Sliding  
Plate  
angle.  
2. Look for the cut edge. The cut  
edge should point towards the  
lever pivot. The CPU will only  
fit in the correct orientation.  
Cut edge  
Close  
Lever  
3. Hold the CPU down firmly,  
and then close the lever to  
complete the installation.  
Overheating will seriously damage the CPU and system,  
always make sure the cooling fan can work properly to  
protect the CPU from overheating.  
WARNING!

Hardware Setup  
Thermal Issue for CPU  
As processor technology pushes to faster speeds and higher performance,  
thermal management becomes increasingly crucial when building computer  
systems. Maintaining the proper thermal environment is key to reliable  
operation. As such, the processor must be maintained in the specified thermal  
requirements. AMD recommends the use of high performance thermal inter-  
face material.  
AMD Athlon™ processor with a speed of 600MHz and above requires LARGER  
heatsink and fan. You also need to add thermal grease between the CPU and  
heatsink to improve heat dissipation. Then, make sure that the CPU and heatsink  
are securely fastened and in good contact with each other. These are needed  
to prevent damaging the processor and ensuring reliable operation.  
You can check AMD’s web site for more information on proper cooling.

Chapter 2  
Memory  
The mainboard provides 2 slots for 184-pin, 2.5V unbuffered DDR DIMM  
with 4 memory banks. You can install PC1600 or PC2100 DDR SDRAM mod-  
ules on the DDR DIMM slots (DDR 1~2). To operate properly, at least one  
DIMM module must be installed.  
Note: The DDR DIMM slots DO NOT support PC2700 modules.  
Introduction to DDR SDRAM  
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,  
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as  
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod-  
ules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of  
DDR SDRAM are available at the time of writing: PC1600, PC2100.  
The following table shows the clock and peak bandwidth of each type of  
DDR SDRAM module:

Hardware Setup  
DDR Module Combination  
You can install either single sided or double sided 184-pin DDR DIMM  
modules into DDR DIMM slots to meet your needs. Different from the SDR  
DIMM, the DDR DIMM has only one notch on the center of module. The  
number of pins on either side of the breaks are different. The module will only  
fit in the right orientation.  
You can install memory modules in any combination as follows:

Power Supply  
The mainboard supports ATX power supply for the power system. Be-  
fore inserting the power supply connector, always make sure that all compo-  
nents are installed properly to ensure that no damage will be caused.  
ATX 20-Pin Power Connector: JWR1  
This connector allows you to connect to an ATX power supply. To  
connect to the ATX power supply, make sure the plugs of the power supply is  
inserted in the proper orientation and the pins are aligned. Then push down  
the power supply firmly into the connector. The power connector supports  
instant power on function which means that system will boot up immediately  
when the power supply connector is inserted on the board.

Jumpers  
The motherboard provides one jumper for you to set the computer’s  
function. This section will explain how to change your motherboard’s function  
through the use of the jumper.  
Clear CMOS Jumper: JBAT1  
There is a CMOS RAM on board that has a power supply from external  
battery to keep the data of system configuration. With the CMOS RAM, the  
system can automatically boot OS every time it is turned on. That battery has  
long life time for at least 5 years. If you want to clear the system configuration,  
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions  
below to clear the data:

You can clear CMOS by shorting 2-3 pin while the  
system is off. Then return to 1-2 pin position. Avoid  
clearing the CMOS while the system is on; it will  
damage the mainboard.

The motherboard provides three 32-bit Master PCI bus slots, one AGP  
slot and one CNR slot.  
AGP Slot  
PCI Slots  
CNR Slot  
AGP (Accelerated Graphics Port) Slot  
The AGP slot allows you to insert the AGP graphics card. AGP is an  
interface specification designed for the throughput demands of 3D graphics.  
It introduces a 66MHz, 32-bit channel for the graphics controller to directly  
access main memory. The slot supports 1.5V/3.3V 2x/4x AGP card.  
PCI Slots  
Three PCI slots allow you to insert the expansion cards to meet your  
needs. When adding or removing expansion cards, make sure that you unplug  
the power supply first. Meanwhile, read the documentation for the expansion  
card to make any necessary hardware or software settings for the expansion  
card, such as jumpers, switches or BIOS configuration.  
CNR (Communication Network Riser)  
The CNR slot allows you to insert the CNR expansion cards. CNR is a  
specially designed audio, or modem riser card for ATX family motherboards.  
Its main processing is done through software and controlled by the  
motherboard’s chipset.

AWARD® BIOS Setup  
DRAMFrequency(MHz)  
Use this item to configure the clock frequency of the installed SDRAM.  
Settings options are:  
HCLK  
HCLK-33  
The DRAM clock will be equal to the host clock.  
The DRAM clock will be equal to the host clock minus 33  
MHz. For example, if the host clock is 133 MHz, the  
DRAM clock will be 100 MHz.  
HCLK+33  
Auto  
The DRAM clock will be equal to the host clock plus  
33MHz. For example, if the host clock is 100 MHz, the  
DRAM clock will be 133 MHz.  
DRAM clock frequency is determined by the contents of  
SPD EEPROM on the DRAM module.  
DRAMCASLatency  
This controls the timing delay (in clock cybles) before SDRAM starts a  
read command after receiving it. Settings: Auto, 2, 2.5, 3 (T=clock cycle).  
2 (clocks) increases the system performance to the most extreme extent  
while 3 (clocks) provides the most stable performance.  
Bank Interleave  
Set the option to Auto for the system to select the appropriate bank  
interleave for the installed SDRAM. Disable the function if 16MB SDRAM  
is installed. Settings: Disabled, Auto.  
Row Precharge  
This item controls the number of cycles of Row Address Strobe (RAS) to  
be allowed to precharge. If insufficient time is allowed for the RAS to  
accumulate its charge before DRAM refresh, refresh may be incomplete  
and DRAM may fail to retain data. This item applies only when  
synchronous DRAM is installed in the system. Available settings: 2T,  
3T, Auto.  
RAS Pulse  
This setting allows you to select the number of clock cycles allotted for  
the RAS pulse width, according the DRAM specifications. The less the  
clock cycles, the faster the DRAM performance. Settings: 6T, 5T, Auto.  
3-13  
Chapter 3  
RAS to CAS  
Use this feature to set the number of cycles for a timing delay between the  
CAS and RAS strobe signals, used when DRAM is written to, read from  
or refreshed. Fast speed offers faster performance while slow speed offers  
more stable performance. Settings: 3T, 2T, Auto.  
Burst Length  
This setting allows you to set the size of Burst-Length for DRAM. Bursting  
feature is a technique that DRAM itself predicts the address of the next  
memory location to be accessed after the first address is accessed. To  
use the feature, you need to define the burst length, which is the actual  
length of burst plus the starting address and allows internal address  
counter to properly generate the next memory location. The bigger the  
size, the faster the DRAM performance. Settings: Auto, 4, 8.  
DRAMCommandRate  
This setting controls the SDRAM command rate. Selecting 1T allows  
SDRAM signal controller to run at 1 clock cycle rate. Selecting 2T makes  
SDRAM signal controller run at 2 clock cycle rate. 1T is faster than 2T.  
Setting options: 2T, 1T.  
Current Host (FSB) Clock/DRAM Frequency  
These features show the current host clock and DRAM clock frequency.  
(read only)  
Current DDR Frequency  
This read-only feature will show up only if DDR is installed.  
AGP & P2P Bridge Control

address range dedicated to graphics memory address space. Host  
cycles that hit the aperture range are forwarded to the AGP without any  
translation. The option allows the selection of an aperture size of 4, 8,  
16, 32, 64, 128, and 256 (MB).  
AGPMode  
The item sets an appropriate mode for the installed AGP card. Setting  
options: 1x, 2x, 4x, Auto. Select 4x only if your AGP card supports it.  
AGP Driving Control  
This item allows you to adjust the AGP driving force. Choose Manual to  
key in a AGP Driving Value in the next selection. This feature is  
recommended to set to Auto for avoing any error in your system.  
AGP Driving Value  
This item allows you to adjust the AGP driving force.  
AGP Fast Write  
This option enables or disables the AGP Fast Write feature. The Fast  
Write technology allows the CPU to write directly to the graphics card  
without passing anything through the system memory and improves the  
AGP 4X speed. Select Enabled only when the installed AGP card supports  
this function. Settings: Enabled, Disabled.  
AGP Master 1 W/S Write

trum function reduces the EMI generated by modulating the pulses so that the  
spikes of the pulses are reduced to flatter curves. If you do not have any EMI  
problem, leave the setting at Disabled for optimal system stability and  
performance. But if you are plagued by EMI, change the setting for EMI  
reduction. Remember to disable Spread Spectrum if you are overclocking be-  
cause even a slight jitter can introduce a temporary boost in clockspeed which  
may just cause your overclocked processor to lock up. Options: Disabled,

When you select this function, a message as below will appear on the screen:  
Type the password, up to eight characters in length, and press <Enter>. The  
password typed now will replace any previously set password from CMOS  
memory. You will be prompted to confirm the password. Retype the password  
and press <Enter>. You may also press <Esc> to abort the selection and not  
enter a password.  
To clear a set password, just press <Enter> when you are prompted to enter the  
password. A message will show up confirming the password will be disabled.  
Once the password is disabled, the system will boot and you can enter Setup  
without entering any password.  
When a password has been set, you will be prompted to enter it every time you  
try to enter Setup. This prevents an unauthorized person from changing any  
part of your system configuration.  
Additionally, when a password is enabled, you can also have BIOS to request  
a password each time the system is booted. This would prevent unauthorized  
use of your computer. The setting to determine when the password prompt is  
required is the Security Option of the Advanced BIOS Feature menu. If the  
Security Option is set to System, the password is required both at boot and at  
entry to Setup. If set to Setup, password prompt only occurs when you try to  
enter Setup.
