Please realize that there is a certain risk involved with overclocking, including adjust-
ing the setting in the BIOS, applying Untied Overclocking Technology, or using third-
party overclocking tools. Overclocking may aect your system’s stability, or even cause
damage to the components and devices of your system. It should be done at your own
risk and expense. We are not responsible for possible damage caused by overclocking.
1. Whether 2400/2100MHz memory speed is supported depends on the AM3/AM3+
CPU you adopt. If you want to adopt DDR3 2400/2100 memory module on this
motherboard, please refer to the memory support list on our website for the compatible
memory modules. ASRock website: http://www.asrock.com
2. Due to the operating system limitation, the actual memory size may be less than 4GB
for the reservation for system usage under Windows® 32-bit OS. For Windows® 64-bit
OS with 64-bit CPU, there is no such limitation. You can use ASRock XFast RAM to
utilize the memory that Windows® cannot use.

is is an ATX form factor motherboard. Before you install the motherboard, study
the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Make sure to unplug the power cord before installing or removing the motherboard.
Failure to do so may cause physical injuries to you and damages to motherboard
components.
• In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.2 Installing the CPU Fan and Heatsink
Aer you install the CPU into this motherboard, it is necessary to install a larger
heatsink and cooling fan to dissipate heat. You also need to spray thermal grease
between the CPU and the heatsink to improve heat dissipation. Make sure that the
CPU and the heatsink are securely fastened and in good contact with each other.
en connect the CPU fan to the CPU FAN connector. For proper installation,
please kindly refer to the instruction manuals of the CPU fan and the heatsink.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology.
Dual Channel Memory Conguration
e DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the DIMM if you force the DIMM into the slot at incorrect
orientation.

1Populated Populated
2Populated Populated
3Populated Populated Populated Populated
1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR3 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one or three
memory module installed.
3. It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot;
otherwise, this motherboard and DIMM may be damaged.
4. Please install the memory module into DDR3_A2 and DDR3_B2 slots for the rst
priority.
5. If you adopt DDR3 2400/2100 memory modules on this motherboard, it is recom-
mended to install them on DDR3_A2 and DDR3_B2 slots.
