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.

English

CAUTION!

1. This motherboard supports Untied Overclocking Technology. Please read “Un-

tied Overclocking Technology” on page 26 for details.

2. 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 12 for proper installation.

3. Whether 1800/1600MHz memory speed is supported depends on the AM3

CPU you adopt. If you want to adopt DDR3 1800/1600 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

4. 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.

5. The maximum shared memory size is defined by the chipset vendor and

is subject to change. Please checkAMD website for the latest information.

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

For audio output, this motherboard supports 2-channel, 4-channel, 6-channel,

and 8-channel modes. Please check the table on page 3 for proper connection.

7. Before installing SATAII hard disk to SATAII connector, please read the “SATAII

Hard Disk Setup Guide” on page 29 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. 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

9. 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: http://www.asrock.com

ASRock 785G Pro Motherboard

10. ASRock Instant Flash is a BIOS flash utility embedded in Flash ROM.

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.

11. 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.

12. 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.

13. 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.

14. 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.

Installation

This is an ATX form factor (12.0-in x 8.8-in, 30.5 cm x 22.4 cm) motherboard.

Before you install the motherboard, study the configuration of your chassis to en-

sure that the motherboard fits into it.

Pre-installation PrecautionsPre-installation Precautions

Pre-installation Precautions

Take note of the following precautions before you install motherboard

components or change any motherboard settings.

Before you install or remove any component, ensure that the

power is switched off or the power cord is detached from the

power supply. Failure to do so may cause severe damage to the

motherboard, peripherals, and/or components.

1. Unplug the power cord from the wall socket before touching any

component.

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 anti-

static 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.
