 WARNING

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.  About the setting of “Hyper Threading Technology”, please check page 

66 of “User Manual” in the support CD.

2.  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 16 for proper installation.

3.  DDR3 frequency options may depend on the processor. Only K-Series 

CPU can support DDR3 overclock to 2133 and 1866. 

4.  Due to the operating system limitation, the actual memory size may be 

less than 4GB for the reservation for system usage under Windows

®

 / XP. For Windows

®

 OS with 64-bit CPU, there is no such limita-

tion. 

5.  The maximum shared memory size is de

fi

 ned by the chipset vendor and 

is subject to change. Please check Intel

®

 website for the latest informa-

tion.

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

HDMI and DisplayPort 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 HDMIport.

7.  xvYCC and Deep Color are only supported under Windows

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

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

nel, 6-channel, and 8-channel modes. Please check the table on page 3 

for proper connection.

9.  ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to 

fi

 ne-tune 

different system functions in a user-friendly interface, which is including 

Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In 

Hardware Monitor, it shows the major readings of your system. In Fan 

Control, it shows the fan speed and temperature for you to adjust. In 

Overclocking, you are allowed to overclock CPU frequency for optimal 

system performance. In OC DNA, you can save your OC settings as a 

pro

fi

 le and share with your friends. Your friends then can load the OC 

pro

fi

 le to their own system to get the same OC settings. In IES (Intelligent 

Energy Saver), the voltage regulator can reduce the number of output 

phases to improve efficiency when the CPU cores are idle without 

sacrificing computing performance. Please visit our website for the 

operation procedures of ASRock Extreme Tuning Utility (AXTU).

17.  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 sys-

tem.

18.  Combo Cooler Option (C.C.O.) provides the 

fl

 exible option to adopt three 

different CPU cooler types, Socket LGA 775, LGA 1155 and LGA 1156. 

Please be noticed that not all the 775 and 1156 CPU Fan can be used. 

19.  EuP, stands for Energy Using Product, was a provision regulated by Eu-

ropean Union to de

fi

 ne 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 ef

fi

 ciency 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.
