Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports Intel® Pentium® 4 processors using a Socket 478. Before building your
system, we suggest you visit the Intel website and review the processor installation procedures.
CPU Socket 478 Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end of
the lever. Match the dot on the CPU with the pin-1 receptor on the socket and lower the CPU onto the
socket. The bottom of the CPU should be flush with the face of the socket.

Pin1 Receptor
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps on
the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it onto the
CPUFAN adapter.
Attention
Overheating may damage the CPU and other sensitive components.
Please check the installation completely before starting the system.
Make sure the heatsink and the CPU fan are properly installed.

Chapter 2. BIOS Setup
Introduction
This section describes PHOENIX-AWARD™ BIOS Setup program which resides in the BIOS
firmware. The Setup program allows users to modify the basic system configuration. The
configuration information is then saved to CMOS RAM where the data is sustained by battery after
power-down.
The BIOS provides critical low-level support for standard devices such as disk drives, serial ports
and parallel ports. As well, the BIOS controls the first stage of the boot process, loading and
executing the operating system.
The PHOENIX-AWARDTM BIOS installed in your computer system’s ROM is a custom version of
an industry standard BIOS. This means that it supports the BIOS of Intel® based processors.
This version of the PHOENIX-AWARDTM BIOS includes additional features such as virus and

Frequency/Voltage Control
CPU Host Frequency (MHz)
This item displays the CPU Host frequency . You can set it from XXX to 550 (or 255). The default
depends on your CPU frequency. The default for this field depends on the CPU installed.
CPU Clock Ratio 8X
When you enable this field, the CPU clock ratio is fixed at “8X” and overrides the entry for the “CPU
Clock Ratio” field (see “CPU Clock Ratio” field). The CPU clock ratio is used, in part, to determine
the CPU clock speed (CPU clock speed = CPU clock ratio * CPU Host Frequency). It has been
shown that a higher “CPU Host Frequency” and a lower “CPU Clock Ratio” is more desirable when
calculating a desired CPU clock speed. This field allows you to set the CPU clock ratio to a lower
than usual value (8X), allowing you to use higher “CPU Host Frequency” values.
When you disable this field, the CPU clock ratio will be determined by the “CPU Clock Ratio” field.
This item will only appear when the CPU clock ratio is not locked by the CPU manufacturer.
Options: Enabled, Disabled (default)
CPU Clock Ratio
This field will only display if the CPU has not been set to a locked state by the CPU manufactory. If

This item determines the AGP, PCI and SRC frequencies (speed settings). You can set these
frequencies using the supplied BIOS options. One of the options available to you is “Auto, Auto,
Auto”. Using the “Auto, Auto, Auto” option will instruct the system to automatically calculate these
frequencies based on the factory default “CPU Host Frequency” setting, the current “CPU Host
Frequency” setting and the formulas in the table below. Note that the factory default “CPU Host
Frequency” is the value of the “CPU Host Frequency” when you first received your system.

To determine your new frequencies, you must first take the factory default “CPU Host Frequency”
and then determine the corresponding formulas according to the table above. Second, take the current
“CPU Host Frequency” setting and apply it to the formulas to arrive at your new frequencies.
For example, if your factory default “CPU Host Frequency” was 100, and you reset the “CPU Host
Frequency” to 133, your AGP, PCI and SRC frequencies will be as follows:
32
PX875P PRO/ PX875P
AGP Frequency = 133 / 1.5 = 88.67
PCI Frequency = 133 / 3
SRC Frequency = 133 / 1

OnChip IDE Device
IDE HDD Block Mode
Block mode is otherwise known as block transfer, multiple commands, or multiple sector read/write.
Select the “Enabled” option if your IDE hard drive supports block mode (most new drives do). The
system will automatically determine the optimal number of blocks to read and write per sector.
Options: Enabled (default)、Disabled
On-Chip Primary/Secondary PCI IDE
The mainboard chipset contains a PCI IDE interface with support for two IDE channels. Select
“Enabled” to activate the first and/or second IDE interface. Select “Disabled” to deactivate the
interface if you are going to install a primary and/or secondary add-in IDE interface. Options:
Enabled (default)、Disabled
34
PX875P PRO/ PX875P
IDE Primary/Secondary/Master/Slave PIO
The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each of the IDE
devices that the onboard IDE interface supports. Modes 0 to 4 will increase performance
incrementally. In Auto mode, the system automatically determines the best mode for each device.
Options: Auto (default)、Mode0、Mode1、Mode2、Mode3、Mode4.
IDE Primary / Secondary /Master / Slave UDMA
Ultra DMA 100 functionality can be implemented if it is supported by the IDE hard drives in your
system. As well, your operating environment requires a DMA driver (Windows 95 OSR2 or a third
party IDE bus master driver). If your hard drive and your system software both support Ultra DMA
100, select “Auto” to enable BIOS support. Options: Auto (default)、Disabled
***OnChip Serial ATA Setting***
On-Chip Serial ATA
This field allows you to select the on-chip Serial ATA operating mode which will determine how you
will use your Serial ATA drives with the other standard IDE drives. This system can physically
attach 4 IDE drives and 2 SATA drives but will have certain limitations as described below.
Options: Disabled
Auto (default)
Disable on-chip serial ATA. No Serial ATA devices installed.
BIOS will auto-detect the presence of any SATA devices.
Note: When using the “Auto” mode with Windows®
98/ME/2000 and installing drives on all 4 IDE connectors and
both SATA drives, the system will only recognize 2 of the IDE
drives along with the 2 SATA drives (this will be similar to the
“Combined” Mode – see below).
Combined Mode
Windows® 98/ME/2000 can recognize IDE devices but cannot
directly recognize an SATA device and therefore you must use
this mode to allow the SATA device to simulate an IDE device
by assuming the role of one of the two IDE channels in the
system. This means that you will only have one available IDE
channel left, leaving you with a total of 2 IDE drives and 2
SATA drives for use (each IDE channel can support 2 IDE
drives). If you were to install all four IDE drives and both

Appendix I: Over Clocking
Important
Before you attempt to overclock your system, we strongly recommend that you obtain a thorough
understanding of all of the variables, procedures, and the potential risks associated with overclocking.
Because we cannot control of all of the possible variables that exist (i.e. memory, AGP card, user
configurations, cooling apparatus etc), we cannot assume responsibility from damage to any
components of your system due to overclocking.
What is overclocking?
Overclocking is accelerating the processing speed of certain components of your system above and
beyond what those components were rated for. With this mainboard, depending on the model, you
may be able to overclock some or all of the following:
‹
‹
‹
‹
‹
‹
CPU Speed
FSB (Front Side Bus) frequency
DDR (Memory) frequency
AGP (Accelerated Graphics Port) frequency
PCI (Peripheral Connect Interface) frequency
SRC (Serial Reference Clock) frequency
How to calculate your new frequencies.
With this mainboard, the frequencies mentioned above are calculated using individual formulas.
These formulas have a single “CPU Host Frequency” in common. For each of the items above there
is also a multiplier or a divisor that is applied to the “CPU Host Frequency” to determine the final
frequency for each component as shown in the following formulas.
CPU Speed
=
=

*
*
/
CPU Clock Ratio
FSB multiplier
DDR:CPU Ratio
AGP divisor
FSB frequency
DDR frequency
AGP frequency
PCI frequency
SRC frequency
/
PCI divisor
/
SRC divisor
Configuring your system for overclocking is simply understanding the formulas above and going into
the BIOS Setup Utility and changing “DDR:CPU Ratio”, “CPU Clock Ratio” and “CPU Host
Frequency”.
Note that the FSB multiplier for Intel based mainboards will always be fixed at 4. The AGP, PCI and
SRC frequencies are all determined by the BIOS setting AGP/ PCI/ SRC Speed Setting.
52
PX875P PRO/ PX875P
How to configure your new frequencies.
As mentioned you must enter the BIOS Setup Utility in order to begin configuring overclocking
parameters. After you reboot your system, press the “Del” key when prompted to enter the BIOS
Setup Utility. The parameters for overclocking will be found in the “Advanced” screen as part of the
“Frequency/Voltage Control” section.
BIOS Setup Utility Overclocking Variables
The following items are all variables in the BIOS Setup Utility that are related to overclock
configurations. See the BIOS section for additional information about these fields including available
options.
CPU Clock Ratio
The CPU Clock Ratio is used to determine the CPU Speed. The CPU Clock Ratio may be locked by
the CPU manufacturer. In this case the value will be displayed but will not be configurable.
CPU Host Frequency (MHz)
This field represents the CPU Clock that is used by all of the previously described formulas to arrive
at the individual frequencies (CPU Speed, FSB, DDR, AGP, PCI, SRC).
DDR:CPU Ratio
This field is used to calculate DDR frequency. To calculate the DDR frequency, simply take the
“CPU Host Frequency” and multiply it by this number.
CPU Voltage/ AGP Voltage/ DDR Voltage
As you increase the frequency of your components, the voltages may not be sufficient to support the
faster speeds and you may begin to encounter problems. When you increase voltages it is important
to remember that you will be increasing the heat generated by the chipsets which could result in
damage. So it is recommended that you slowly increase these values in the increments provided by
the BIOS Setup Utility. The CPU, AGP and DDR all have individual configurable voltage options.
Spread Spectrum
We recommend that you disable this function before you overclock your system.
53
PX875P PRO/ PX875P
AGP/PCI/SRC Speed Setting
This item determines the AGP, PCI and SRC frequencies (speed settings). You can set these
frequencies using the supplied BIOS options. One of the options available to you is “Auto, Auto,
Auto”. Using the “Auto, Auto, Auto” option will instruct the system to automatically calculate these
frequencies based on the factory default “CPU Host Frequency” setting, the current “CPU Host
Frequency” setting and the formulas in the table below. Note that the factory default “CPU Host
Frequency” is the value of the “CPU Host Frequency” when you first received your system.
Factory Default
“CPU Host
Frequency”
Formulas (using the “Auto, Auto, Auto option)
AGP frequency
PCI frequency
SRC frequency
AGP frequency
PCI frequency
SRC frequency
AGP frequency
PCI frequency
SRC frequency
= current CPU Host Frequency / 1.5
= current CPU Host Frequency / 3
= current CPU Host Frequency / 1
= current CPU Host Frequency / 2
= current CPU Host Frequency / 4
= current CPU Host Frequency / 1.33
= current CPU Host Frequency / 3
= current CPU Host Frequency / 6
= current CPU Host Frequency / 2
100
133
200
To determine your new frequencies, you must first take the factory default “CPU Host Frequency”
and then determine the corresponding formulas according to the table above. Second, take the current
“CPU Host Frequency” setting and apply it to the formulas to arrive at your new frequencies.
* Your AGP, PCI or SRC devices may begin to malfunction because they are unable to handle
certain speeds that are calculated using the “Auto,Auto,Auto” option, in which case you can fix the
frequencies for these devices using the other available options for this field. And if you want to
overcolock a system with SATA HDDs, we strongly to remind you to fix the AGP/PCI/SRC Speed to
“66.68, 33.34, 100.02”.
Configuration Suggestions
Before attempting overclocking, you should write down all of the default BIOS settings for the
variables described in the previous sections. This is so you can return to the original values if you run
into problems.
The next suggestion is to adjust in small steps and not to increase the options too fast. This is
especially true with Voltage since increasing the voltage can significantly increase temperature. After
adjusting the BIOS settings and rebooting your system, always check the CPU temperatures that are
displayed in the BIOS Setup Utility (HW Section). Tolerable temperatures for your CPU will be
listed with the specifications provided by your CPU manufacturer.
Because increasing voltages is the biggest factor in increasing temperatures, you should only increase
voltages as a last option when your system is continuing to experience problems. When you do
increase the voltages, increase them only one increment at a time.
54
PX875P PRO/ PX875P
Testing
Even though you have configured your overclocking options and have successfully booted to your
operating system, it doesn’t mean that you have successfully overclocked your system. Testing is an
equally important aspect of overclocking and you must stress your configurations thoroughly to
ensure stability. It is better to discover that your system locks up during testing rather than
experiencing the same while editing valuable information.
There are several utility programs designed specifically for intensive hardware configuration testing
such as 3Dmark2001SE and Winstone. With every configuration adjustment you should rerun your
utilities. Testing is a time consuming procedure. Again, it is not within the scope of this document to
discuss testing utilities in detail. You can find additional information on the Web.
Cooling the components on your mainboard.
Proper cooling is one the most important aspects of overclocking. Cooling refers to the cooling fans,
heat sinks, and thermal material/grease that are used. When overclocking, it is highly recommended
that you acquire a large powerful cooling fan with a heavy duty heat sink. Also make sure that you
apply certified thermal material between the CPU and heatsink. It is also recommended that you
make use of all of the fan attachments and make sure that cable clutter within the casing is kept to a
minimum. It is beyond the scope of this document to explain cooling equipment in detail so we
recommend that you consult the Web for more information. CPU manufacturers may also have a list
of recommended, certified cooling equipment.
The Watch Dog Timer
Some mainboards come with a special feature called the Watch Dog Timer used to simplify the
process of experimenting with overclocking. When you go too far with your overclocking
configurations there is a chance that your system may become unstable and hang. Even after a reboot,
the system may hang before you can even reach the BIOS Setup Utility to lower your settings. The
usual procedure with most Mainboards is to open up your case and reset a CMOS jumper on the
mainboard to restore the original default settings which can be a cumbersome activity when testing.
The Watch Dog Timer however, will monitor the most recent boot information or POST (Power On
Self Test) status to determine if the system booted successfully. If the last POST status was “not
successful”, it will be assumed there were configuration problems and the system will automatically
reset the BIOS configurations which will allow your system to boot again.
