2.2 Before you proceed
Take note of the following precautions before you install components into the
system.
•
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.
The system motherboard comes with an onboard standby power LED. This LED
lights up to indicate that the system is ON, in sleep mode or in soft-off mode, and
not powered OFF. Unplug the power cable from the power outlet and make sure
that the standby power LED is OFF before installing any system component.

2.4 Installing a CPU
R
CPU Socket 775
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.
This system is designed for Intel® 65W desktop processors. Other Intel®
processors higher than 65W may not provide optimum performance.
Refer to ASUS CPU support list for more details.
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us.
2.4.1 CPU installation
• Your boxed Intel® 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 make sure that the socket contacts are not
bent. Contact your retailer immediately if you see any damage to the socket
contacts/motherboard components. ASUS will shoulder the cost of repair
only if the damage is shipment/transit-related.
• The product warranty does not cover damage to the socket contacts
resulting from incorrect CPU installation or removal.
Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, make sure that the socket box is facing towards you
and the load lever is on your left.
2-5ASUS P3-P5G31
2. Press the load lever with your thumb (A) and move it to the left (B) until it is
released from the retention tab.

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.
4. Lift the load plate with your thumb
and forenger to a 100º angle (A),
then push the PnP cap from the load
plate window to remove (B).

5. Position the CPU over
the socket, making sure
that the gold triangle is
on the bottom-left corner
of the socket. The socket
alignment key should t into
the CPU notch.

6. Close the load plate (A), then push
the load lever (B) until it snaps into
the retention tab.
The CPU ts 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!
The motherboard supports Intel® LGA775 processors with the Intel® Enhanced
Memory 64 Technology (EM64T), Enhanced Intel SpeedStep® Technology
(EIST), and Hyper-Threading Technology. Refer to the Appendix for more
information on these CPU features.

2-7ASUS P3-P5G31
2.4.2 Installing the CPU fan and heatsink assembly
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®-certied multi-directional heatsink and fan.
®
• Your Intel
and requires no tool to install.
If you purchased a separate CPU heatsink and fan assembly, make sure that
the Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.
LGA775 heatsink and fan assembly comes in a push-pin design
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.

DIMM_B1
DIMM_A1
The motherboard comes with two 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:
ChannelSockets
Channel ADIMM_A1
Channel BDIMM_B1
Install a memory module in DIMM_A1 slot to support the Intel® Quiet System
Technology and for optimum performance.
2-10Chapter 2: Basic installation
2.5.1 Memory congurations
You may install 256 MB, 512 MB, 1 GB and 2 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
conguration. 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.
• If you are using a Windows 31-bit version operating system (e.g. 32-bit
Windows XP, 32-bit Windows Vista) without the Physical Address Extension
(PAE) support, the system will allocate a certain amount of memory space for
system devices.
• We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;
however, the system can not use this excess memory space and the
system will display less than the total size of physical memory installed.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
4 GB on the operating systems listed below. You may install a maximum
of 2 GB DIMMs on each slot, but only DDR2-800 and DDR2-667 2 GB
density modules are available for this conguration.
Windows
Windows® 2003 Server
Windows
• Some old-version DDR2-800 DIMMs may not match Intel®
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR-667. If this happens, contact your memory vendor to check
the ODT value.
