Chapter 1: Product introduction
1.2 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.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, 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, or components.
1.3 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts.
Ensure that you unplug the power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard components.
1.3.1 Placement direction
When installing the motherboard, place it into the chassis in the correct orientation. The edge
with external ports goes to the rear part of the chassis as indicated in the image.

1.4 Accelerated Processing Unit (APU)
F1A55 R2.0
F1A55 R2.0 CPU socket FM1
This motherboard comes with an FM1 socket designed for AMD® Fusion™ A- & E2- series
accelerated processors with AMD® Radeon™ HD 6000 series graphics.
Use an APU designed for the FM1 socket. The APU ts in only one correct orientation. DO
NOT force the APU into the socket to prevent bending the pins and damaging the APU!
1.4.1 Installing the CPU
Unplug all power cables before installing the CPU.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1155 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.
To install an APU:
1. Locate the FM1 socket on the motherboard.
2. Press the lever sideways to unlock the
socket, then lift it up to a 90°-100° angle.

3. Position the APU above the socket such that the APU
corner with the gold triangle matches the socket corner
with a small triangle.
4. Carefully insert the APU into the socket until it ts in place.
The APU ts only in one correct orientation.
DO NOT force the APU into the socket to
prevent bending the pins and damaging the
APU!

5. When the APU is in place, push down the socket
lever to secure the APU. The lever clicks on the side
tab to indicate that it is locked.
6. Install a APU heatsink and fan following the
instructions that comes with the heatsink package.
You can also refer to section 1.6.2 Installing
heatsink and fan for instructions.
7. Connect the CPU fan cable to the CPU_FAN connector on the motherboard.

DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if
you fail to plug this connector.

Chapter 1: Product introduction
1.4.2 Installing the heatsink and fan
Use only AMD-certied heatsink and fan assemblies.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed CPU, ensuring that the heatsink ts properly
on the retention module base.
• The retention module base is already installed on the motherboard upon purchase.
• You do not have to remove the retention module base when installing the CPU or
installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, apply Thermal Interface
Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.

Your boxed CPU heatsink and fan assembly 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.
