CAUTION!
1. Intel®CoreTM i3 and Pentium®G6950 processors do not support Intel®
Turbo Boost Technology.
2. About the setting of “Hyper Threading Technology”, please check page 41
of “User Manual” in the support CD.
3. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 25 for details.
4. This motherboard supportsDual Channel Memory Technology. Before you
implement Dual Channel Memory Technology, make sure to read the
installation guide of memory modules on page 13 for proper installation.
5. Due to the operating system limitation, the actual memory size may be
less than 4GB for the reservation for system usage under Windows®7 /
VistaTM / XP. For Windows®OS with 64-bit CPU, there is no such limitation.
6. For those CPU that only support up to DDR3 1333, the XMP DDR3 1600
is supported through overclocking.
7. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check Intel®website for the latest information.
8. Before installing SATAII hard disk to SATAII connector, please read the
“SATAII Hard Disk Setup Guide” on page 28 of “User Manual” in the support
CD to adjust your SATAII hard disk drive to SATAII mode. You can also
connect SATA hard disk to SATAII connector directly.
9. Power Management for USB 2.0 works fine under Microsoft®Windows® 7
64-bit / 7 / VistaTM 64-bit / VistaTM / XP 64-bit / XP SP1 or SP2.
10. It is a user-friendly ASRock overclocking tool which allows you to surveil
your system by hardware monitor function and overclock your hardware
devices to get the best system performance under Windows® environment.
Please visit our website for the operation procedures of ASRock OC
Tuner.
ASRock website: http://www.asrock.com/feature/OCTuner/index.htm
11. Featuring an advanced proprietary hardware and software design,
Intelligent Energy Saver is a revolutionary technology that delivers
unparalleled power savings. In other words, it is able to provide exceptional
power saving and improve power efficiency without sacrificing computing
performance. Please visit our website for the operation procedures of

13. The software name itself – OC DNA literally tells you what it is capable of.
OC DNA, an exclusive utility developed by ASRock, provides a conve-
nient way for the user to record the OC settings and share with others. It
helps you to save your overclocking record under the operating system
and simplifies the complicated recording process of overclocking settings.
With OC DNA, you can save your OC settings as a profile and share with
your friends! Your friends then can load the OC profile to their own system
to get the same OC settings as yours! Please be noticed that the OC
profile can only be shared and worked on the same motherboard.
14. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
15. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
16. EuP, stands for Energy Using Product, was a provision regulated by
European Union to define the power consumption for the completed system.
According to EuP, the total AC power of the completed system shall be
under 1.00W in off mode condition. To meet EuP standard, an EuP ready
motherboard and an EuP ready power supply are required. According to
Intel’s suggestion, the EuP ready power supply must meet the standard of
5v standby power efficiency is higher than 50% under 100 mA current
consumption. For EuP ready power supply selection, we recommend you
checking with the power supply manufacturer for more details.

Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
2. To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the carpet
or the like. Also remember to use a grounded wrist strap or touch
a safety grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded
antstatic pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the
motherboard to the chassis, please do not over-tighten the
screws! Doing so may damage the motherboard.

For the installation of Intel 1156-Pin CPU,
please follow the steps below.
Before you insert the 1156-Pin CPU into the socket, please check if
the CPU surface is unclean or if there is any bent pin on the socket.
Do not force to insert the CPU into the socket if above situation is
found. Otherwise, the CPU will be seriously damaged.

Step 1. Open the socket:
Step 1-1. Disengaging the lever by depressing
down and out on the hook to clear re-
tention tab.
Step 1-2. Rotate the load lever to fully open posi-
tion at approximately 135 degrees.
Step 1-3. Rotate the load plate to fully open posi-
tion at approximately 100 degrees.
Step 2. Remove PnP Cap (Pick and Place Cap).
1. It is recommended to use the cap tab to handle and avoid kicking
off the PnP cap.
2. This cap must be placed if returning the motherboard for after
service.
Step 3. Insert the 1156-Pin CPU:
Step 3-1. Hold the CPU by the edges where are
marked with black lines.
Step 3-2. OrienttheCPUwithIHS(IntegratedHeat
Sink) up. Locate Pin1 and the two ori-
entation key notches.

2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3)DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-
type)DDR3 DIMM pair in the slots of the same color. In other words, you have to
install identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1;
white slots; see p.2 No.6), so that Dual Channel Memory Technology can be
activated. This motherboard also allows you to install four DDR3 DIMMs for dual
channel configuration, and please install identical DDR3DIMMs in all four slots.
You may refer to the Dual Channel Memory Configuration Table below.
Dual Channel Memory Configurations

(2)* Populated Populated Populated Populated
* For the configuration (2), please install identical DDR3 DIMMs in all four
slots.
1. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of white slots
(DDR3_A1 and DDR3_B1).
2. If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot;otherwise, this motherboard and DIMM may be damaged.
4. Please install the memory module into the white slot (DDR3_B1) for
the first priority.

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits 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.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and theDIMM is properly seated.
