1.3.4ASUS Intelligent Overclocking features

AI Booster

The ASUS AI Booster allows you to overclock the CPU speed in Windows environment without the hassle of booting the BIOS. See page 5-26 for details.

Precision Tweaker

This feature allows you to fine tune the CPU/memory voltage and gradually increase the memory Front Side Bus (FSB) and PCI Express frequency at 1MHz increment to achieve maximum system performance. See page 4-17 to 4-19 for details.

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 the BIOS automatically restores the CPU default setting for each parameter.

2.1Before you proceed

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.

•Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components 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, and/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 should 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.

2.2Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.

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

2.2.1Placement 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.

2.2.2Screw holes

Place six (6) 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.

Place this side towards the rear of the chassis

2.3Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Quad / Core™2 Extreme / Core™2 Duo / Pentium® Extreme / Pentium® D / Pentium® 4 processors.

• Make sure that all power cables are unplugged before installing the CPU.

• Connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability.

• Upon purchase of the motherboard, make sure 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

MerchandiseAuthorization (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.

2.3.1Installing the CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

P5K SE/EPU

P5K SE/EPU CPU Socket 775

Before installing the CPU, make sure that the socket box is facing towards you and the load lever is on your left.

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

Retention tab				A			PnP cap
Load lever
				B
					This side of the socket box
					should face you.

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.

The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!

6.	Close the load plate (A), then	A
	push the load lever (B) until it
	snaps into the retention tab.
7.	If installing a dual-core CPU,	B
	connect the chassis fan cable
	to the CHA_FAN1 connector to
	ensure system stability.
