Getting Started
1.1 Safety Precautions
Warning!
Always 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 CPU card. 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
1.2 Packing List
Before you begin installing the single board, make sure that the following materials are
included in the package:
1 x EAX-Q77 ATX Motherboard
1 x CD-ROM contains OS drivers/QIG/User’s Manual
2 x COM cable
2 x SATA cable
1 x I/O shield

Hardware Installation
2.1 Before Installation
Before installing the motherboard, take note of the following considerations and safety
information.
Warning!
Always disconnect the power cord from the chassis before
working on the motherboard.
Only experienced electronics personnel should open the
PC chassis.
1. Ensure that the motherboard can fit into the chassis.
2. Always unplug the power cord before installing or removing the motherboard or
any of its components.
3. Use a grounded wrist strap or touch a grounded object before handling any of the
components.
4. When attaching screws to secure the motherboard to the chassis, do not over
tighten the screws to avoid damaging the motherboard.

2.2 Installing the CPU
Perform the following steps to install the CPU:
Note: Before installing the CPU, ensure that the surface of the CPU is clean and
the pins are not bent.
1. Press the lever and slide it out of the hook.
2. Lift to open the socket cover.
3. Install the CPU making sure the gold triangle is located in the correct direction.

6EAX-Q77 Quick Installation Guide
Warning!
Do not force to insert the CPU into the socket. If the CPU
does not fit, check for proper orientation. Forcing the CPU
into the socket may damage the CPU.
4. Close the socket cover.
5. Press the lever down and slide it under the hook.

2.3 Installing the CPU Fan and Heat Sink
Perform the following steps to install the CPU fan and heat sink:
1. Apply the thermal grease onto the center of the CPU socket surface.
2. Align and install the CPU fan and heat sink.
3. Tighten the heat sink screws.

4. Connect the fan header onto the CPU fan connector on the motherboard.
Note: Make sure the heat sink and the CPU top surface are in total contact to
avoid CPU overheating problems that may cause the system to hang or be
unstable.

2.4 Installing a Memory Module
EAX-Q77 provides four (4) 240-pin DDR3 Dual In-Line Memory Module (DIMM) sockets
which support data transfer rates of 1333 and 1600 MT/sec. The total maximum memory
size is 32 GB.
Perform the following steps to install a memory module to the motherboard:
1. Press the retaining clips outwards.
2. Align a memory module on the slot taking note of the break on the module and the slot.
3. Insert the memory module completely until the retaining clips at both ends lock up and
the memory module is seated in place.
Note:
(1) Do not change any of the DDR3 DIMM parameters in BIOS setup without
acquiring technical information in advance.
(2) Static electricity can damage the electronic components of the computer or the
optional boards. Before starting these procedures, ensure that you are
discharged of static electricity by touching a grounded metal object briefly.

2.5 Jumper and Connector List
2.5.1 Jumper List
You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper, connect the pins with the clip. To
“open” a jumper, remove the clip. Sometimes a jumper has three pins, labeled 1, 2, and 3.
In this case, connect either two pins.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.
The following table lists the jumpers on your board.
