2-5ASUS T3-P5945GCX

2.5 CPU installation

• Your boxed Intel® Pentium® 4 LGA775 processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match
the CPU documentation, follow the latter.

•

Check your motherboard to ensure that the PnP cap is on the CPU 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.

2.5.1 Installing the CPU

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

To install a CPU:

1. Locate the CPU socket on the motherboard.

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

2. Press the load lever with your thumb

(A), then move it to the left (B) until it
is released from the retention tab.

2.5.2 Installing CPU fan and heatsink assembly

The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.

• When you buy a boxed Intel® Pentium® 4 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

®

Pentium® 4 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 the
Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.

To install the CPU heatsink and fan:

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

2. Push down two fasteners at a time in

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

2.6 Installing a DIMM

The system motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline

Memory Module (DIMM) sockets.

The following gure illustrates the location of the sockets:

• Installing DDR2 DIMMS other than the recommended congurations
may cause memory sizing error or system boot failure. Use any of the
recommended congurations in the table on the next page.

• Install only

identical (the same type and size) DDR2 DIMMs in DIMM_A1

and DIMM_B1.

• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor.

• Due to chipset resource allocation, the system may detect less than 2 GB
system memory when you installed two 1 GB DDR2 memory.

• This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules.

2.6.1 Memory congurations

You may install up to 2 GB system memory using 256 MB, 512 MB, and 1 GB
DDR2 DIMMs.

5.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) chip that you
can update using the provided utility described in section “5.1 Managing and

updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to“Run Setup.” This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration of your computer in the future. For example, you can enable the

security password feature or change the power management settings. This

requires you to recongure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the

LPC chip.

The LPC chip on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press

<Del> during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise,

POST continues with its test routines.

If you wish to enter Setup after POST, reboot the system by doing any of the
following procedures:

• Restart using the OS standard shut-down procedure.

• Press <Ctrl>+<Alt>+<Del> simultaneously.

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to
force reset from a running operating system can cause damage to your data

or system. We recommend to always shut-down the system properly from the

operating system.

The Setup program is designed to make it as easy to use as possible. Being a

menu-driven program, it lets you scroll through the various sub-menus and make

your selections from the available options using the navigation keys.

• The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Default Settings item under the

Exit Menu. See section “5.7 Exit Menu.”

• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
