Introduction
Thank you for choosing 845PE-A800 motherboard of great performance and with en-
hanced function. 845PE-A800 motherboard carries a ATX form factor of 305 x 204 mm.
845PE-A800 supports Socket 478 Pentium 4 processors with system bus speeds up to 800
(overclocking, requires using DDR400)/533/400MHz.
845PE-A800 incorporates chipset of Intel 845PE Northbridge and ICH4 Southbridge.
845PE(MCH) Northbridge supports a single processor with FSB of 800 (overclocking,
requires using DDR400)/533/400 MHz, DDR-SDRAM at 400 (overclocking)/333/266MHz
operation. It supports 64-Mb, 128-Mb, 256-Mb and 512-Mb SDRAM technology.
The ICH4 Southbridge integrates IDE controller supporting Ultra ATA/100/66/33, BMIDE
and PIO modes. It implements three UHCI host controllers that provide 480Mb/s band-
width for six external USB2.0 ports, integrates AC’97 v2.3 compliant controller that
features a 6-channel of audio speaker out. The southbridge also integrates a PCI interface
controller, and LAN controller supporting 10/100 Mbit/s ethernet.
There is an advanced full set of I/O ports in the rear panel, including PS/2 mouse and
keyboard connectors, COM1, LPT1, and four USB ports, one optional LAN port, and audio
jacks for microphone, line-in, and line-out. In addition to its excellent performance and
stability, the motherboard is highly suited for Internet and rich multimedia applications,
including streaming video download and are ideal for workstations and high-end home use.
FSB 800MHz is made possible by overclocking on this motherboard.
When a CPU with 800MHz FSB is installed, users need to use DDR400
SDRAM module.

SafetyPrecautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid damage from
static electricity
• Discharge static electricity by touching the metal case of a safely grounded
object before working on the motherboard
• Leave components in the static-proof bags they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
ChoosingaComputerCase
There are many types of computer cases on the market. The motherboard complies with
the specifications for the ATX system case. First, some features on the motherboard are
implemented by cabling connectors on the motherboard to indicators and switches on the
system case. Make sure that your case supports all the features required. Secondly, 845PE-
A800 supports one or two floppy diskette drives and four enhanced IDE drives. Make sure
that your case has sufficient power and space for all drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O
template in the case matches the I/O ports installed on the rear edge of the motherboard.
This motherboard carries a ATX form factor of 305 x 204 mm. Choose a case that
accommodates this form factor.
InstallingtheMotherboard inaCase
Refer to the following illustration and instructions for installing the motherboard in a case.
Most system cases have mounting brackets installed in the case, which correspond the holes
in the motherboard. Place the motherboard over the mounting brackets and secure the
motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion slots
on your motherboard.

CheckingJumperSettings
This section explains how to set jumpers for correct configuration of the motherboard.
SettingJumpers
Use the motherboard jumpers to set system configuration options. Jumpers with more than
one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on
the correct pins.
The illustrations show a 2-pin jumper. When
the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT
SHORT OPEN
Do not over-tighten the screws as this can stress the motherboard.

Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that data
is being read from or written to the hard drive. For the LED to function properly, an IDE
drive should be connected to the onboard IDE interface. The LED will also show activity
for devices connected to the SCSI (hard drive activity LED) connector.
Front Panel Header
The front panel header (PANEL1) provides a standard set of switch and LED headers
commonly found on ATX or micro-ATX cases. Refer to the table below for information:

InstallingHardware
Installing the Processor
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change these settings by making changes
to jumpers on the motherboard, or changing the settings in the system Setup Utility. We
strongly recommend that you do not over-clock processors or other components to run
faster than their rated speed.
This motherboard has a Socket 478 processor socket. When choosing a processor, consider
the performance requirements of the system. Performance is based on the processor design,
the clock speed and system bus frequency of the processor, and the quantity of internal
cache memory and external cache memory.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentary-contact
switch that is normally open. When the switch is closed, the board resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-
contact switch that is normally open. The switch should maintain contact for at least 50 ms
to signal the power supply to switch on or off. The time requirement is due to internal de-
bounce circuitry. After receiving a power on/off signal, at least two seconds elapses before
the power supply recognizes another on/off signal.
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount
resistors with the clip of the cooling fan. If the clip of the cooling fan
scrapes across the motherboard, you may cause serious damage to the
motherboard or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the motherboard and processor socket.
Warning: Over-clocking components can adversely affect the reliability of
the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides power
on/off, sleep, and message waiting indication.

13
InstallingtheMotherboard
1 Install your CPU. Pull up the lever away
from the socket and lift up to 90-degree
angle.
2 Locate the CPU cut edge (the corner with the
pin hold noticeably missing). Align and insert
the CPU correctly.
3 Press the lever down and apply thermal
grease on top of the CPU.
4 Put the CPU Fan down on the retention
module and snap the four retention legs of
the cooling fan into place.
5 Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan
power cable to the CPUFAN connector. This
completes the installation.
CPU Installation Procedure
The following illustration shows CPU installation components.
To achieve better airflow rates and heat dissipation, we suggest that you use a
high quality fan with 4800 rpm at least. CPU fan and heatsink installation
procedures may vary with the type of CPU fan/heatsink supplied. The form
and size of fan/heatsink may also vary.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installing Memory Modules
845PE-A800 accommodates two 184-pin 2.5V unbuffered Double Data Rate (DDR) SDRAM
(Synchronous Dynamic Random Access Memory) memory modules, and supports DDR400
(overclocking)/333/266 memory modules. Each module can be installed with 1GB of memory,
the total maximum memory size is 2 GB.
