Safety Precautions
Warning!
Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections while
the power is on. Sensitive electronic components can be damaged by
sudden power surges. Only experienced electronics personnel should
open the PC chassis.
Caution!
Always ground yourself to remove any static charge before touching
the mainboard. Modern electronic devices are very sensitive to static
electric charges. As a safety precaution, use a grounding wrist strap at
all times. Place all electronic components in a static-dissipative surface
or static-shielded bag when they are not in the chassis.

1.4 Before you proceed
Take note of the following precautions before you install motherboard components or change any
motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Use a grounded wrist strap or touch a safely grounded object or to 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.
• Before you install or remove any component, ensure that the ATX power supply is switched
off or the power cord is detached from the power supply. Failure to do so may cause severe
damage to the motherboard, peripherals, and/or components.

15
1.5 Mainboard Overview
Before you install the mainboard, study the configuration of your chassis to ensure that the motherboard fits
into it.
Make sure to unplug the power cord before installing or removing the mainboard. Failure
to do so can cause you physical injury and damage mainboard components.
1.5.1 Placement direction
When installing the mainboard, make sure that you place it into the chassis in the correct orientation. The
edge with external port goes to the rear part of the chassis as indicated in the image below.
1.5.2 Screw holes
Place the screws into the holes indicated by circles to secure the mainboard to the chassis.
Do not over-tighten the screws! Doing so may damage the mainboard.

1.5.3 Mainboard Layout

17
1.6 Central Processing Unit (CPU)
This mainboard supports Intel® 65nm Core™ 2 Quad (Q6x00 Series), Core™ 2 Duo (E6x00, E4x00
Series), Pentium® 4 (6x1 series), Pentium® D (9xx Series), Celeron 440 in LGA775 package (with
1333/1066/800MHz FSB only). When you are installing the CPU, make sure to install the cooler to prevent
overheating. If you do not have the CPU cooler, consult your dealer before turning on the system.
• Your boxed Intel® LGA775 processor package should come with installation instructions for the
CPU, fan and heatsink assembly.
• Upon purchase of the mainboard, make sure that the PnP cap is on the socket and the socket
pins are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket pins/motherboard components. BCM will shoulder the cost of
repair only, if the damage is shipment/ transit-related.
• Keep the PnP cap after installing the mainboard. BCM will process Return Merchandise
Authorization (RMA) requests only if the mainboard comes with the cap on the LGA775 socket.
• The product warranty does not cover damage to the socket pins resulting from incorrect CPU
installation/removal, or misplacement/loss/incorrect removal of the PnP cap.
1. Overheating: Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste between the CPU and the
heatsink to enhance heat dissipation.
2. Replacing the CPU: While replacing the CPU, always turn off the ATX power suppply
or unplug the power supply’s powr cord from the grounded outlet first to prevent
damage to the system and the system.

18
1.6.1 Installing the CPU
To install a CPU
1. Locate the CPU socket on the motherboard
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 have
installed the CPU.
3. Lift the load lever in the direction of the arrow to a 135°angle

19
4. Lift the load plate with your thumb and forefinger to a 100°angle (A), then push the PnP cap from the
load plate window to remove (B).
5. Position the CPU over the socket, making sure the gold triangle is on the bottom-left corner of the
socket. The socket alignment key should fit 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 fits in only one correct orientation, DO NOT force the CPU into the socket to prevent
damage to the socket pins or CPU.

20
1.6.2 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 purchase 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.
Note: Make sure that you have installed the mainboard 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.
Note: Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan
connector.
Make sure to orient each fastener with the narrow end of the groove pointing outward.
(The photo shows the groove shaded for emphasis.)
