Please realize that there is a certain risk involved with overclocking, including adjusting the setting in the BIOS, applying Untied Overclocking Technology, or using thirdparty overclocking tools. Overclocking may afect 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.Whether 2400/2100MHz memory speed is supported depends on the AM3/AM3+ CPU you adopt. If you want to adopt DDR3 2400/2100 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® 32-bit OS. 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.

Chapter 2 Installation

his is a Micro ATX form factor motherboard. Before you install the motherboard, study the coniguration of your chassis to ensure that the motherboard its into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard components or change any motherboard settings.

Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause physical injuries to you and damages to motherboard components.

In order to avoid damage from static electricity to the motherboard’s components, NEVER place your motherboard directly on a carpet. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle the components.

Hold components by the edges and do not touch the ICs.

Whenever you uninstall any components, place them on a grounded anti-static pad or in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not overtighten the screws! Doing so may damage the motherboard.

2.2 Installing the CPU Fan and Heatsink

Ater you install the CPU into this motherboard, it is necessary to install a larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU and the heatsink to improve heat dissipation. Make sure that the CPU and the heatsink are securely fastened and in good contact with each other. hen connect the CPU fan to the CPU FAN connector. For proper installation, please kindly refer to the instruction manuals of the CPU fan and the heatsink.

2.3 Installing Memory Modules (DIMM)

his motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,

and supports Dual Channel Memory Technology.

1.For dual channel coniguration, you always need to install identical (the same brand, speed, size and chip-type) DDR3 DIMM pairs.

2.It is unable to activate Dual Channel Memory Technology with only one or three memory module installed.

3.It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot; otherwise, this motherboard and DIMM may be damaged.

4.Please install the memory module into DDR3_A2 and DDR3_B2 slots for the irst priority.

5.If you adopt DDR3 2400/2100 memory modules on this motherboard, it is recommended to install them on DDR3_A2 and DDR3_B2 slots.

2.4 Expansion Slots (PCI and PCI Express Slots)

here is 1 PCI slot and 3 PCI Express slots on the motherboard.

Before installing an expansion card, please make sure that the power supply is switched of or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation.

PCI slot:

he PCI1 slot is used to install expansion cards that have 32-bit PCI interface.

PCIe slots:

PCIE1 (PCIe 2.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE2 (PCIe 2.0 x16 slot) is used for PCI Express x16 lane width graphics cards. PCIE3 (PCIe 2.0 x16 slot) is used for PCI Express x4 lane width cards.
