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 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.

CAUTION!

1. About the setting of “Hyper Thre ading T echnology”, please check page 57 of “User Manual” in the support CD.

2. This motherboard supports Untied Overclocking Technology. Please read “Untied Overclocking Technology” on page 35 for details.

3. 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.

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® XP 64-bit and Windows® OS with 64-bit CPU, there is no such limitation.

5. For those CPU that only support up to DDR3 1333, the XMP DDR3 1600 is supported through overclocking.

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. 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.

Pre-installation PrecautionsPre-installation Precautions

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

1. Unplug the power cord from the wall socket before touching any component. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

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 antstatic 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.

tion at approxi mately 135 degrees .

Step 1-3. Rotate the load plate to fully open posi-

tion at approxi mately 100 degrees .

Step 2. Remove PnP Cap (Pick a nd Pla ce Cap).

1. It is recommended to use the cap tab to handle and avoid kicking off the PnP cap.

2. This cap must be placed if returning the motherboard for after service.

Step 3. Insert the 1 156-Pin CPU:

Step 3-1. Hold the CPU by the edges where are

For proper installation, plea se kindly refer to the instruction ma nuals of your CPU fan a nd heatsink.

Below is an example to illustrate the installation of the heatsink for 1156-Pin CPU. Step 1. Apply thermal interface material onto center of

IHS on the socket surface.

Step 2. Place the heatsink onto the socket. Ensure

fan cables are oriented on side closest to the CPU fan connector on the motherboard (CPU_FAN1, see page 2, No. 5).

Step 3. Align fasteners with the motherboard

throughholes.

Step 4. Rotate the fastener clockwise, then press down

on fastener caps with thumb to install and lock. Repeat with remaining fasteners.

If you press down the fasteners without rotating them clockwise, the heatsink cannot be secured on the motherboard.

Step 5. Connect fan header with the CPU fan connector on the motherboard. Step 6. Secure excess cable with tie-wrap to ensure cable does not interfere with

fan operation or contact other components.

Please be noticed that this motherboard supports Combo Cooler Option (C.C.O.), which provides the flexible option to adopt two different CPU cooler types, Socket LGA 775 and LGA 1156. The white throughholes are for Socket LGA 1156 CPU fan.

2.3 Installation of Memory Modules (DIMM)2.3 Installation of Memory Modules (DIMM)

This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install identical (the same brand, speed, size and chiptype) DDR3 DIMM pair in the slots of the same color. In other words, you have to install identical DDR3 DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1; white slots; see p.2 No.7), so that Dual Channel Memory Technology can be activated. This motherboard also allows you to install four DDR3 DIMMs for dual channel configuration, and please install identical DDR3 DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration Table below.

Dual Channel Memory Configurations

DDR3_A2 DDR3_A1 DDR3_B2 DDR3_B1

(Blue Slot) (White Slot) (Blue Slot) (White Slot) (1) - Populated - Populated (2)* Populated Populated Populated Populated

* For the configuration (2), please install identical DDR3 DIMMs in all four

slots.

1. If you want to install two memory modules, for optimal compatibility and reliability, it is recommended to install them in the slots of the same color. In other words, install them either in the set of white slots (DDR3_A1 and DDR3_B1).

2. If only one memory module or three memory modules are installed in the DDR3 DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory T e chnology.

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

4. Please install the memory module into the white slot (DDR3_B1) for the first priority.

Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Unlock a DIMM slot by pre ssing the retaining cli ps outward. Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the break

on the slot.

The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully

There are 2 PCI slots and 5 PCI Express slots on this motherboard. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI

interface.

PCIE slots:

PCIE1 / PCIE3 / PCIE4 (PCIE x1 slot; White) is used for PCI Express cards with x1 lane width cards, such as Gigabit LAN card, SATA2 card, etc. PCIE2 / PCIE5 (PCIE x16 slot; Blue) is used for PCI Express x16 lane width graphics cards, or used to install PCI Express graphics cards to support CrossFireXTM or SLITM function.

1. In single VGA card mode, it is recommended to install a PCI Express x16 graphics card on PCIE2 slot.

2. In CrossFireXTM mode or SLITM mode, please install PCI Express x16 graphics cards on PCIE2 and PCIE5 slots. Therefore, both these two slots will work at x8 bandwidth.

3. Please connect a chassis fan to motherboard chassis fan connector (CHA_FAN1, CHA_FAN2 or CHA_FAN3) when using multiple graphics cards for better thermal environment.
