WA R NING

Please realize that there is a certain risk involved with overclocking, including adjusting

the setting in the BIOS, applying Untied Overclocking Technology, or using the third-

party overclocking tools. Overclocking may affect your system 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.

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 46.

3. This motherboard supports Untied Overclocking Technology. Please read

“Untied Overclocking Technology” on page 38 for details.

4. This motherboard supports Dual Channel Memory Technology. Before you

implement Dual Channel Memory Technology, make sure to read the

installation guide of memory modules on page 19 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 /

/ XP. For Windows® OS with 64-bit CPU, there is no such limitation.

Vista

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. You can choose to use two of the three monitors only. D-Sub, DVI-D and

HDMI monitors cannot be enabled at the same time. Besides, with the DVI-

to-HDMI adapter, the DVI-D port can support the same features as HDMI

port.

9. xvYCC and Deep Color are only supported under Windows

Deep Color mode will be enabled only if the display supports 12bpc in

EDID. HBR is supported under Windows® 7 64-bit / 7 / VistaTM 64-bit /

Vista

10. For microphone input, this motherboard supports both stereo and mono

modes. For audio output, this motherboard supports 2-channel, 4-channel,

This convenient BIOS update tool allows you to update system BIOS

without entering operating systems first like MS-DOS or Windows®. With

this utility, you can press <F6> key during the POST or press <F2> key to

BIOS setup menu to access ASRock Instant Flash. Just launch this tool

and save the new BIOS file to your USB flash drive, floppy disk or hard

drive, then you can update your BIOS only in a few clicks without prepar-

ing an additional floppy diskette or other complicated flash utility. Please

be noted that the USB flash drive or hard drive must use FAT32/16/12 file

system.

16. 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.

17. 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.

18. 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.

19. Combo Cooler Option (C.C.O.) provides the flexible option to adopt two

different CPU cooler types, Socket LGA 775 and LGA 1156. Please be

noticed that not all the 775 CPU Fan can be used.

20. 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.

This motherboard is equipped with 1156-Pin socket that supports Intel 1156-Pin CPU.

Please adopt the type of heatsink and cooling fan compliant with Intel 1156-Pin CPU

to dissipate heat. Before you installed the heatsink, you need to spray thermal

interface material between the CPU and the heatsink to improve heat dissipation.

Ensure that the CPU and the heatsink are securely fastened and in good contact with

each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see

page 12, No. 3).

For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink.

Below is an example to illustrate the installation of the heatsink for 1156-Pin CPU.

Step 1. Apply thermal interface material onto center of

IHS on the socket surface.
