Gigabyte GA-7DXR+ User manual

FCCComplianceStatement:
This equipment has been tested and found to
comply with limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable
protection against harmful interference in
residential installations. This equipment
generates, uses, and can radiate radio
frequency energy, and if not installed and used
in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference
will not occur in a particular installation. If this
equipment does cause interference to radio or
television equipment reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna
-Move the equipment away from the receiver
-Plug the equipment into an outlet on a circuit different from that to which
the receiver is connected
-Consult the dealer or an experienced radio/television technician for
additional suggestions
You are cautioned that any change or modifications to the equipment not
expressly approve by the party responsible for compliance could void Your
authority to operate such equipment.
This device complies with Part 15 of the FCC Rules. Operation is subjected to
the following two conditions 1) this device may not cause harmful interference
and 2) this device must accept any interference received, including interference
that may cause undesired operation.

Installation Guide
Getting Started
WARNING!
Computer motherboards and expansion cards contain very delicate Integrated
Circuit (IC) chips. To protect them against damage from static electricity, you
should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have one,
touch both of your hands to a safely grounded object or to a metal object, such as the
power supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.
4. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
5. Ensure that theATX power supply is switched off before you plug in or remove the ATX
power connector on the motherboard.
Installing the motherboard to the chassis…
If the motherboard has mounting holes, but they don’t line up with the holes on the base and
there are no slots to attach the spacers, do not become alarmed you can still attach the spacers
to the mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard
to cut off, so be careful of your hands). In this way you can still attach the motherboard to the
base without worrying about short circuits. Sometimes you may need to use the plastic springs
to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by
the hole. Be careful, don’t let the screw contact any printed circuit write or parts on the PCB that
are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

CPU Installation
Please make sure the CPU should be supported to the motherboard.
CPU Top View
CPU Bottom View
1. Pull up the CPU socket lever
and up to 90-degree angle.
2. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper corner. Then insert the CPU
into the socket.
CPU Heat Sink Installation:
Beware: Please check that the heat sink is in good contact with the CPU before you turn on your
system. The poor contact will cause over heat, and mightcause damage to your
processor!

3.Align CPU and insert it
(Please refer to your heatsink installation
manual for application of thermal grease to
provide better heat conduction between your
CPU and heatsink.)
4.Use compliant fan approved byAMD.
5.Hook one end of the cooler bracket to the CPU socket.
6. Hook the other end of the cooler bracket to the CPU socket.
(Please refer to the cooler’s installation manual for detailed installation steps)
