ASUS EZ Flash 2

ASUS EZ Flash 2 is a utility that allows you to update the BIOS without using an OS-based utility.

1-2 Chapter 1: Product introduction

ASUS EPU

The ASUS EPU (Energy Processing Unit) provides total system power management by detecting current PC loading and intelligently moderating power in real-time. It automatically provides the most appropriate power usage to save power and money!

ASUS Express Gate

Express Gate is an ASUS exclusive OS, which lets you instantly access the Internet and key applications before entering the Windows® OS.

• ASUS Express Gate supports installation on SATA HDDs, USB HDDs and ash

drives with at least 1.2GB free disk space. When installing it on USB HDDs or

ash drives, connect the drives to the motherboard USB port before turning on the

computer.

• The actual boot time depends on the system conguration.

• ASUS Express Gate supports le uploading from SATA HDDs, ODDs and USB drives. It supports le downloading to USB drives only.

ASUS AI NET2

ASUS AI NET2 remotely detects the cable connection immediately after turning on the system, and any faulty cable connections are reported back up to 100 meters at 1 meter accuracy.

Turbo Key

ASUS Turbo Key allows you to turn the PC power button into a physical overclocking button. After the easy setup, Turbo Key can boost performances without interrupting ongoing work or games—with just one touch!

Anti-Surge

Anti-Surge prevents expensive devices and the motherboard from damage caused by power surges from switching power supply (PSU).

C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.

Green ASUS

This motherboard and its packaging comply with the European Union’s

Restriction on the use of Hazardous Substances (RoHS). This is in line

with the ASUS vision of creating environment-friendly and recyclable

products/packaging to safeguard consumers’ health while minimizing the

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

1-4 Chapter 1: Product introduction

1.5 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to ensure that the motherboard ts into it.

Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components.

1.5.1 Placement direction

When installing the motherboard, ensure 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.

1.5.2 Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.

P5P43T

P5P43T CPU socket 775

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme / Core™2 Quad / Core™2 Duo / Pentium® dual-core /Celeron® dual-core processors.

• Unplug all power cables before installing the CPU.

• Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.

• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.

• Keep the cap after installing the motherboard. ASUS will process Return Merchandise

Authorization (RMA) requests only if the motherboard comes with the cap on the

LGA775 socket.

• The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

The motherboard supports Intel® LGA775 processors with the Intel® Enhanced Intel SpeedStep® Technology (EIST) and Hyper-Threading Technology.

1.6.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, ensure that the cam box is facing towards you and the load lever is on your left.

ASUS P5P43T 1-7

2. Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.

To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3. Lift the load lever in the direction of the

arrow to a 135º angle.

4. Lift the load plate with your thumb and

forenger to a 100º angle (4A), then

push the PnP cap from the load plate window to remove (4B).

5. Position the CPU over the socket, ensuring that the gold triangle is on the

bottom-left corner of the socket then t

the socket alignment key into the CPU notch.

6. Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer.

Some heatsinks come with pre-applied thermal paste. If so, skip this step.

DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin, ensure that you wash it off immediately, and seek professional medical help.

To prevent contaminating the paste, DO NOT spread the paste with your nger directly.

7. Close the load plate (A), then push the load lever (B) until it snaps into the retention tab.

ASUS P5P43T 1-9

1.6.2 Installing the CPU heatsink and fan

The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

•

When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel®-certied multi-directional heatsink and fan.

• Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.

• If you purchased a separate CPU heatsink and fan assembly, ensure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.

Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.

To install the CPU heatsink and fan:

1. Place the heatsink on top of the installed CPU, ensuring that the four fasteners match the holes on the motherboard.

Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector.

2. Push down two fasteners at a time in a

diagonal sequence to secure the heatsink and fan assembly in place.

The type of CPU heatsink and fan assembly may differ, but the installation steps and functions should remain the same. The illustration above is for reference only.
