Dual Channel interface:
• Dual channel memory access offers increased system performance.
• For dual channel to operate, both channel must be populated with same amount of memory, preferably
of the same type.
• The four DIMM sockets are divided into two colors to help you identify the channel pairs <Figure 1>. Each

Introduction

English
3-1 Main Menu
The ROM BIOS contains a built-in Setup program which allows user to modify the basic system configuration and
hardware parameters. The modified data is stored in a battery-backed CMOS, so that data will be retained even
when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there
is a configuration change in the system, such as hard drive replacement or a device is added.
It is possible for the CMOS battery to fail causing CMOS data loss. If this happens you will need install a new CMOS
battery and reconfigure your BIOS settings.
To enter the Setup Program :
Power on the computer and press the <Del> key during the POST (Power On Self Test). The BIOS CMOS SETUP
UTILITY opens.
The main menu displays all the major selection items. Select the item you need to reconfigure. The selection is made
by moving the cursor, press any direction (arrow key ) to the item and pressing the ‘Enter’ key. An on-line help
message is displayed at the bottom of the screen as the cursor is moved to various items which provides a better
understanding of each function. When a selection is made, the menu of the selected item will appear so that the user
can modify associated configuration parameters.


The BIOS setup screen and description are for reference only, and may not exactly match
what you see on your screen. The contents of BIOS are subject to change without notice.
Please visit our website for BIOS updates.
Section 3 -- BIOS Setup

For more information regarding BIOS settings refer to the complete manual in the
bundled CD.

3-2 Standard CMOS Setup
Choose “STANDARD CMOS FEATURES” in the CMOS SETUP UTILITY Menu. Standard CMOS Features Setup allows the
user to configure system settings such as the current date and time, type of hard disk drive installed, floppy drive
type, and display type. Memory size is auto-detected by the BIOS and displayed for your reference. When a field is
highlighted (use direction keys to move the cursor and the <Enter> key to select), the entries in the field can be
changed by pressing the <PgDn> or the <PgUp> key.
Notes:
•If the hard disk Primary Master/Slave and Secondary Master/Slave are set to Auto, the hard disk size and
model will be auto-detected.
•The “Halt On:” field is used to determine when the BIOS will halt the system if an error occurs.
3-3 Advanced BIOS Features
Selecting the “ADVANCED BIOS FEATURES” option in the CMOS SETUP UTILITY menu allows users to change system
related parameters in the displayed menu. This menu shows all of the manufacturer’s default values for the board.
Pressing the [F1] key displays a help message for the selected item.

On: The keypad acts as a 10-key pad.
Off: The keypad acts like cursor keys.
Security Option
This category allows you to limit access to the System and Setup, or just to Setup.
System: The system will not boot and access to Setup will be denied unless the correct password is
entered at the prompt.
Setup: The system will boot, but access to Setup will be denied unless the correct password is
entered at the prompt.
APIC Mode
This item allows you to enable APIC (Advanced Programmable Interrupt Controller) functionality.
Options: Enabled, Disabled.
HDD S.M.A.R.T. Capability
The S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) system is a diagnostics technology that
monitors and predicts device performance. S.M.A.R.T. Software resides on both the disk drive and the host
computer. If a device failure is predicted, the host software, through the Client WORKS S.M.A.R.T applet, warns the
user of the impending condition and advises appropriate action to protect the data.
Options: Enabled, Disabled.
Full Screen LOGO Show
This item allows you determine Full Screen LOGO display during POST.
Options: Enabled, Disabled.

3-4 POWER BIOS Features
This page lets you adjust various parameters to obtain improved performance for overclocking.
Warning:
Overclocking requires expert knowledge and risks permanent damage to system components.
We recommend you leave these parameters at their default values for proper operation.
CPU Frequency
Enables you to increment the CPU’s clock generator at 1 MHz step. This works together with CPU Clock Ratio (below)
to set the CPU operating frequency.
CPU Clock Generator x CPU Clock Ratio = CPU Frequency
For example, if you have a processor that is rated at 2.4GHz and the clock generator is 200MHz, then 200MHz x 12
= 2.4GHz
Options: 200 to 450 in 1MHz increments.

 Overclocking failure will cause no display on the monitor. To overcome this switch off the power supply
and switch on again. Restart the system, press and hold < Insert> key. This will revert the BIOS to
default or initial setting.
PCIE Clock
Enables you to subtle tune the PCI-E frequency at increments of 1MHz step.
Options: 100 to 145 in 1MHz increments.
CPU Clock Ratio
Use this item to select a multiplier to set the CPU frequency. See CPU Frequency item above for explanation. If your CPU
multiplier is locked this option will be unavailable.
AMD K8 Cool’n’Quiet
Reduce the noise and heat from your PC when AMD’s Cool’n’QuietTM technology is Auto.
Options: Auto, Disabled.
CPU Voltage
This item allows you to adjust the CPU Vcore voltage.
Options: Off, Auto, -0.200V to +0.350V in 0.025V increments. We recommend that you leave this at the default
value.
Chipset Voltage
This item allows you to adjust the Chipset voltage.
Options: +1.5V to +1.8V in 0.1V increments. We recommend that you leave this at the default value.
