Chapter 1 This chapter describes the features of the motherboard. It includes brief descriptions of the motherboard components, and illustrations of the layout, jumper settings, and connectors.
1.1 Welcome! Thank you for buying the ASUS® P4PE2-X motherboard! The motherboard delivers a host of new features and latest technologies making it another standout in the long line of ASUS quality motherboards! The motherboard incorporates the Intel® Pentium® 4 Processor in 478-pin package coupled with the Intel® 845PE chipset to set a new benchmark for a cost-effective desktop platform solution.
DDR400 memory support Employing the Double Data Rate (DDR) memory technology, the P4PE2-X motherboard supports up to 2GB of system memory using unbuffered non-ECC PC3200*/2700/2100 DDR DIMMs. Memory support depends on the CPU FSB and DDR type. See page 1-12 for the CPU and DIMM requirements. *Overclocking mode Onboard LAN solution The motherboard has the Realtek® RTL8101L chipset onboard to support 10BASE-T/100BASE-TX networking protocol. USB 2.
C.P.R. (CPU Parameter Recall) The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the BIOS default settings in case the system hangs due to overclocking. When the system hangs due to overclocking, C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and BIOS automatically restores the CPU previous setting for each parameter. 1.

1.5.2 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. 1.5.3 Screw holes Place seven (7) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not overtighten the screws! Doing so may damage the motherboard.
1.6 Central Processing Unit (CPU) 1.6.1 Overview The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket designed for the Intel® Pentium® 4 processor. Take note of the marked corner (with gold triangle) on the CPU. This mark should match a specific corner on the socket to ensure correct installation. P4PE2-X ® Gold Arrow P4PE2-X Socket 478 • Intel® Prescott CPUs can only support 533MHz FSB on this motherboard. • 800 MHz FSB works with Intel® Northwood processors only.
1.6.2 Installing the CPU Follow these steps to install a CPU. 1. Locate the 478-pin ZIF socket on the motherboard. 90º~100º angle 2. Unlock the socket by pressing the lever sideways, then lift it up to a 90°100° angle. Socket Lever Make sure that the socket lever is lifted up to 90°-100° angle; otherwise, the CPU does not fit in completely. 3. Position the CPU above the socket such that its marked corner matches the base of the socket lever. Gold Mark 4.
1.7 System memory 1.7.1 DIMM sockets location 80 Pins 104 Pins DIMM2 DIMM1 You can install 64MB, 256MB, 512MB, and 1GB DDR DIMMs into the DIMM sockets of this motherboard. The following figure illustrates the location of the DDR DIMM sockets. P4PE2-X ® P4PE2-X 184-Pin DDR DIMM Sockets • • • Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to the motherboard and other system components.
x16 Double-sided DDR DIMMs (16-bit memory chips) are not supported on this motherboard. This motherboard supports different memory frequencies depending on the CPU FSB (Front Side Bus) and the type of DDR DIMM. Table 1 CPU FSB DDR DIMM Type Memory Frequency *800 MHz *PC3200 *400 MHz 533 MHz PC2700/PC2100 333/266 MHz 400 MHz PC2100 266 MHz * Overclocking mode 1.7.
1.7.4 Installing a DIMM DDR DIMM Follow these steps to install a DIMM. 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket. 3. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated. • • 1.8 Unlocked A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.

1.8.3 PCI slots The PCI slots support PCI cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. 1.8.4 AGP slot The Accelerated Graphics Port (AGP) slot supports AGP 4X (+1.5V) cards. When you buy an AGP card, make sure that you ask for one with +1.5V specification. Note the notches on the card golden fingers to ensure that they fit the AGP slot on the motherboard. Install only +1.5V AGP cards. P4PE2-X ® Keyed for 1.
1.9 Jumpers 1. Clear RTC RAM (CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include system setup information such as system passwords, is powered by the onboard button cell battery. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3.
2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).
