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 thirdparty 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.


1.This motherboard supports Untied Overclocking Technology. Please read “Untied Overclocking Technology” on page 30 for details.

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 14 for proper installation.

3.Whether 1066MHz memory speed is supported depends on the AM2+ CPU you adopt. If you want to adopt DDR2 1066 memory module on this motherboard, please refer to the memory support list on our website for the compatible memory modules.

ASRock website

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 and Windows® VistaTM. For Windows® XP64-bitand Windows® VistaTM 64bit with64-bitCPU, there is no such limitation.

5.The maximum shared memory size is defined by the chipset vendor and is subject to change. Please check AMD website for the latest information.

6.1080p Blu-ray(BD) /HD-DVDplayback support on this motherboard requires the proper hardware configuration. Please refer to page10 and 11 for the minimum hardware requirement and the passed 1080pBlu-ray(BD) /HD-DVDfilms in our lab test.

7.Before installing SATAII hard disk to SATAII connector, please read the “SATAII Hard Disk Setup Guide” on page 30 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.

8.Power Management for USB 2.0 works fine under Microsoft® Windows® VistaTM 64-bit /VistaTM / XP64-bit /XP SP1 or SP2.

9.It is a user-friendlyASRock 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:



ASRock A780FullHD Motherboard

10.Featuring an advanced proprietary hardware and software design, Intelligent Energy Saver is a revolutionary technology that delivers unparalleled power savings. The voltage regulator can reduce the number of output phases to improve efficiency when the CPU cores are idle. In other words, it is able to provide exceptional power saving and improve power efficiency without sacrificing computing performance. To use Intelligent Energy Saver function, please enable Cool ‘n’ Quiet option in the BIOS setup in advance. Please visit our website for the operation procedures of Intelligent Energy Saver.

ASRock website:

11.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.

12.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.

13.This motherboard supports ASRock AM2 Boost overclocking technology. If you enable this function in the BIOS setup, the memory performance will improve up to 12.5%, but the effect still depends on the AM2 CPU you adopt. Enabling this function will overclock the chipset/CPU reference clock. However, we can not guarantee the system stability for all CPU/DRAM configurations. If your system is unstable after AM2 Boost function is enabled, it may not be applicative to your system. You may choose to disable this function for keeping the stability of your system.
