2.4.1 Overview

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

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.

2.4.2 Installing CPU

2.5.1 Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket.

The gure illustrates the location of the DDR2 DIMM sockets:

Channel Sockets

Channel A DIMM_A1 and DIMM_A2

Channel B DIMM_B1 and DIMM_B2

2-8 Chapter 2: Basic installation

2.5.2 Memorycongurations

You may install 512 MB, 1 GB, 2 GB, and 4 GB non-ECC, unbuffered, DDR2
DIMMs into the DIMM sockets.

• Due to chipset behavior, to obtain memory frequency higher than DDR2
800, you can manually adjust DRAM Frequency in BIOS settings. Refer to

5.4 Ai Tweaker menu for details.

• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
conguration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

• It is recommended to install the memory modules from the yellow slots for
better overclocking capability.

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

• When installing total memory of 4GB capacity or more, Windows® 32-bit

operation system may only recognize less than 3GB. Hence, a total

installed memory of less than 3 GB is recommended.

• This motherboard does not support memory modules made up of 256 Mb
chips.

• Due to chipset limitation, this motherboard can only support up to 16 GB
on the operating systems listed below. You may install a maximum of 4 GB
DIMMs on each slot.

64-bit

Windows® XP Professional x64 Edition
Windows® Vista x64 Edition

• The default memory operation frequency is dependent on its SPD. Under
the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value. To operate at the vendor­marked or at a higher frequency, see section 5.4 Ai Tweaker menu for
manual memory frequency adjustment.

• The memory modules may require a better cooling system to work stably
under full loading (4 DIMMs) or overclocking setting.

2.6 Expansion slots

In the future, you may need to install expansion cards. The following sub-sections
describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion
cards. Failure to do so may cause you physical injury and damage motherboard
components.

2.6.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a
chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw
for later use.

4. Align the card connector with the slot and press rmly until the card is

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.6.2 Conguringanexpansion card

After installing the expansion card, congure it by adjusting the software settings.

1. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 5 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support “Share

IRQ” or that the cards do not need IRQ assignments. Otherwise, conicts will

arise between the two PCI groups, making the system unstable and the card
inoperable.

The Vintage V-Series P5G45 barebone system comes with an ASUS motherboard.
This chapter provides technical information about the motherboard for future

upgrades or system reconguration.

4.2 Motherboard layout

4-2 Chapter 4: Motherboard info

4.3 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 onboard button
cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the onboard battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins
2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS setup to
re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

4-3ASUS V-Series P5G45

• If the steps above do not help, remove the onboard battery and move
the jumper again to clear the CMOS RTC RAM data. After the CMOS
clearance, reinstall the battery.

• Yo u do no t n ee d t o cle ar th e RTC when the sy ste m han gs du e to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

• Due to the chipset behavior, AC power off is required to enable C.P.R.
function. You must turn off and on the power supply or unplug and plug the
power cord before rebooting the system.

2. USB device wake-up (3-pin USBPW1-4; USB7-10; USB1112)

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).

The USBPW1-4 jumper is for the rear USB ports. The USBPW7-10 and

USBPW1112 jumpers are for the internal USB connectors that you can
connect to additional USB ports.

• The USB d evice wake-up feature require s a power supp ly tha t ca n

3. Keyboard power (3-pin PS2_USBPW56)

This jumper allows you to enable or disable the keyboard and USB port 5-6

wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can
wake up the computer by pressing a key on the keyboard (the default is
the Space Bar) or using a USB device. This feature requires an ATX power
supply that can supply at least 1A on the +5VSB lead, and a corresponding
setting in the BIOS. The USBPW56 jumper is for the internal USB connectors
that you can connect to additional USB ports.

4.3 Connectors

1. Floppy disk drive connector (34-1 pin FLOPPY)

This connector is for the provided oppy disk drive (FDD) signal cable. Insert

one end of the cable to this connector, then connect the other end to the

signal connector at the back of the oppy disk drive.

Pin 5 on the connector is removed to prevent incorrect cable connection when
using an FDD cable with a covered Pin 5.

4-6 Chapter 4: Motherboard info

2. IDE connector (40-1 pin PRI_EIDE)

The onboard IDE connector is for the Ultra DMA 133/100/66 signal cable. There
are three connectors on each Ultra DMA 133/100/66 signal cable: blue, black,
and gray. Connect the blue connector to the motherboard’s IDE connector, then

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

SPI chip.

The rmware 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, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if

the rst two failed.

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 Setup Defaults item under the
Exit Menu. See section 2.9 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.
