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. http://www.intel.com
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 have a
cut-corner (as shown).
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.
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.
Before starting the system
Please check the installation completely before starting the system.
Verify that the heatsink is properly installed and make sure the CPU fan is

CPU Headers
Three power headers are available for cooling fans, which play an important role in
maintaining the ambient temperature in your system.
The layout is PX845PEV PRO
We strongly recommend you attach the
CPU fan to the CPUFAN Header.

Frequency / Voltage Control
This Mainboard automatically detects and recognizes the CPU ratio. You can otherwise
override these values using the BIOS setup utility.
Configuring the CPU Host Frequency by using the
BIOS Setup Utility
To access the BIOS Setup Utility, reboot your system. During the reboot process you will be
given an opportunity to press the “DEL” key to enter the BIOS Setup Utility.
BIOS SETUP>>Advanced BIOS>>Frequency/Voltage Control>>……
CPU Speed = CPU Clock Ratio * CPU Host Frequency
DDR Speed = DDR: CPU Ratio *CPU Host Frequency
For more details, please refer to Frequency / Voltage Control in Chapter 2 BIOS Setup.
Watch Dog Timer
This mainboard comes with a special feature called “Watch Dog Timer” which is used to
detect when the system is unable to perform using the manual over-clocking configurations.
After you power on the system, BIOS will check the last system POST status. If it was
successful, BIOS will enable the “Watch Dog Timer” feature and set the CPU frequency
values to the user configured values stored in the BIOS. If unsuccessful the “Watch Dog
Timer” will reboot the system.
On most systems you would need to remove the cover of your system and re-jumper the
clear CMOS switches on the mainboard when your system encounters over-clocking
problems. With the “Watch Dog Timer”, overclocking settings will be automatically cleared
and reset.
Before Overclocking
Please make sure your system components are capable of overclocking.
If you are not familiar with the Overclocking function, we strongly recommen
d
that you to set the clock to the default settings.

PX845PEV/ GEV Series

Memory Installation
The PX845PEV/GEV series contains 3 sockets, which use 184 pin DDR SDRAM with a
total memory capacity of up to 2GB. You can install the unbuffered non-ECC DDR333/
DDR266/ DDR200 (PC/2700/ PC2100/ PC1600) SDRAM.
Each DIMM socket is capable of using a memory
module of up to 1GB. However, if you use DIMM2
and DIMM3 at the same time, you must be install the
single-sided memory module and the total memory
used by these two sockets cannot exceed 1GB.
The layout is PX845PEV PRO
RAM Module Installation:
1. Match the notch on the button of the RAM module with the corresponding
pattern in the DIMM slot. This ensures that the module is inserted properly.
2. Lower the RAM module into the DIMM Slot and press firmly using both
thumbs until the module snaps into place.
3. Repeat steps 1 & 2 for the remaining RAM modules.
