Chapter 1: Product introduction
1.6.2 Installing the CPU heatsink and fan
Intel® LGA775 processors require 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 processor 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:
1. Place the heatsink on top of the
installed CPU, making sure 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.

Do not forget to connect the CPU fan connector! Hardware
monitoring errors can occur if you fail to plug this connector.
The retention module of some third-party CPU heatsink and fan
can interfere with chipset components at the bottom of the board.
Before purchasing a separate CPU heatsink and fan, make sure that
it will not interfere with the chipset components.

1.6.3 Uninstalling the CPU heatsink and fan
To uninstall the CPU heatsink and fan:
1. Disconnect the CPU fan cable
from the connector on the
motherboard.
2. Rotate each fastener
counterclockwise.
3. Pull up two fasteners at a
time in a diagonal sequence to

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:
P5N-E SLI 240-pin DDR2 DIMM Sockets
Channel
Sockets
Channel A
Channel B
DIMM_A1 and DIMM_A2
DIMM_B1 and DIMM_B2
1.7.2 Memory configurations
You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
•
For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same
(DIMM_A1 + DIMM_A2 = DIMM_B1 + DIMM_B2).
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from
the same vendor. Refer to the DDR2 Qualified Vendors List on the next
page for details.
•
•
Due to chipset resource allocation, the system may detect less than 8
GB system memory when you installed four 2 GB DDR2 memory modules.
If you install four 1GB memory modules, the system may only recognize
less than 3 GB because the address space is reserved for other critical
functions. This limitation appears on Windows® XP 32-bit operation
system which does not support Physical Address Extension (PAE).
•
If you install Windows® XP 32-bit operation system, a total memory of
less than 3GB is recommended.

Note on memory limitations
The motherboard can support up to 8 GB on the operating systems listed
below. You may install a maximum of 2 GB DIMMs on each slot.

•
A DDR2 DIMM is keyed with a notch so that it fits in only one
direction. Do not force a DIMM into a socket to avoid damaging the
DIMM.
•
The DDR2 DIMM sockets do not support DDR DIMMs. DO not install
DDR DIMMs to the DDR2 DIMM sockets.
1.7.4 Removing a DIMM
Follow these steps to remove a DIMM.

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. 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 firmly 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.
1.8.2 Configuring an expansion card
After installing the expansion card, configure the 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. 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,
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.

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 •words.
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!

Make sure to re-enter your previous BIOS settings after you clear the
CMOS.
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.

The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise,
the system would not power up.
The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
3. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) to wake up the computer
when you press a key on the keyboard (the default is the Space Bar).
This feature requires an ATX power supply that can supply at least 1A
on the +5VSB lead, and a corresponding setting in the BIOS.

BIOS setup program
This motherboard supports a programmable Low-Pin Count (LPC) chip
that you can update using the provided utility described in section “2.1
Managing and updating your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the configuration 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 reconfigure 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, restart the system by pressing
<Ctrl>+<Alt>+<Del>, 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 first 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 Default
Settings item under the Exit Menu. See section “2.8 Exit Menu.”
