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 / Celeron® processors.  
Make sure the AC power is off before you install the CPU.  
If installing a dual-core 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.

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, make sure that you  
use only Intel®-certified 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, make sure  
that you have properly applied Thermal Interface Material to the CPU  
heatsink or CPU before you install the heatsink and fan assembly.  
Make sure 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:  
A
1.  
Place the heatsink on top of the installed  
CPU, making sure that the four fasteners  
match the holes on the motherboard.

System memory  
1.7.1  
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 figure illustrates the location of the DDR2 DIMM sockets:

Memory configurations  
You may install 512 MB, 1 GB, 2GB, and 4 GB unbuffered non-ECC DDR2 DIMMs into the  
DIMM sockets.  
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 configuration. Any excess  
memory from the higher-sized channel is then mapped for single-channel operation.  
Always install DIMMs with the same CAS latency. For optimum compatibility, it is  
recommended that you obtain memory modules from the same vendor.  
Due to the memory address limitation on 32-bit Windows OS, when you install 4GB or  
more memory on the motherboard, the actual usable memory for the OS can be about  
3GB or less. For effective use of memory, we recommend that you install a 64-bit  
Windows OS when having 4GB or more memory installed on the motherboard.  
This motherboard does not support memory modules made up of 256 megabit (Mb)  
chips or less.  
This motherboard supports Intel® ME technology. Your system may detects less  
memory size than that you installed when Intel® ME function is enabled. Refer to the  
following table for details.

Notes on memory limitations  
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 Professional x64 Edition  
The memory operation frequency depends on its Serial Presence Detect  
(SPD). By default, some memory modules for overclocking may run at  
lower frequency than the vendor-marked value. If you want to manually  
adjust the memory frequency, refer to section 2.4 AI Tweaker menu.  
To stabilize the memory modules, use an efficient memory cooling system  
that can support the work load and overclocking conditions.  
The total memory may has 16MB reduction under Single Channel mode,  
and 64MB reduction under Dual Channel mode because the address space  
is reserved for the Intel® vProTechnology and the Intel® Quiet System  
Technology.

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.  
1.8.1  
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.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
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 firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.8.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card. Refer to the tables on the next page.  
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, conflicts will arise between the two PCI  
groups, making the system unstable and the card inoperable. Refer to the table on the next  
page for details.

Jumper  
Clear RTC RAM (3-pin 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.

Clear RTC  
P5Q-EM DO Clear RTC RAM  
To erase the RTC RAM  
1.  
2.  
Turn OFF the computer and unplug the power cord.  
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.  
3.  
4.  
Plug the power cord and turn ON the computer.  
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!  
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.  
You do not need to clear the RTC when the system hangs due 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.

the BIOS Setup program so that the computer can recognize these changes and record them  
in the CMOS RAM of the SPI chip.  
The SPI 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 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.
