CAUTION!

1. Whether 2400/1866/1600MHz memory speed is supported depends on

the CPU you adopt. If you want to adopt DDR3 2400/1866/1600 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

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

less than 4GB for the reservation for system usage under Windows®8 / 7

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

limitation. You can use ASRock XFast RAM to utilize the memory that

Windows®cannot use.

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 third-party overclocking tools. Overclocking may

affect your system’s 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.

1.3 Pin Header Easy Installation Guide

ASRock motherboard is equipped with pin headers with obvious colors which indi-

cate you to recognize the crucial headers more easily. Please refer to below illustra-

tions for the pin deﬁnition of onboard headers. If you want to have more information

about the usage of these headers, please refer to “Jumpers Setup“ and “Onboard

Headers and Connectors“ for details.

1.4 Jumpers Setup

The illustration shows how jumpers are

setup. When the jumper cap is placed on

pins, the jumper is “Short”. If no jumper cap

is placed on pins, the jumper is “Open”. The

illustration shows a 3-pin jumper whose

pin1 and pin2 are “Short” when jumper cap

is placed on these 2 pins.

Jumper Setting Description

Clear CMOS Jumper

(CLRCMOS1)

(see p.2, No. 26)

Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the

system parameters to default setup, please turn off the computer and unplug

the power cord from the power supply. After waiting for 15 seconds, use a

jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,

please do not clear the CMOS right after you update the BIOS. If you need

to clear the CMOS when you just ﬁnish updating the BIOS, you must boot

up the system ﬁrst, and then shut it down before you do the clear-CMOS ac-

tion. Please be noted that the password, date, time, user default proﬁle, 1394

GUID and MAC address will be cleared only if the CMOS battery is removed.

1.5 Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place

jumper caps over these headers and connectors. Placing jumper caps

over the headers and connectors will cause permanent damage of the

motherboard!

Serial ATA3 Connectors These four Serial ATA3

(SATA_1: see p.2, No. 12) (SATA3) connectors support

(SATA_2: see p.2, No. 13) SATA data cables for internal

(SATA_3: see p.2, No. 11) storage devices. The current

(SATA_4: see p.2, No. 10) SATA3 interface allows up to

6.0 Gb/s data transfer rate.

this motherboard. Each USB 2.0

header can support two USB

2.0 ports.

(9-pin USB8_9)
