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 Threading Technology”, please check page 29 of “User Manual” in the support CD.

2. This motherboard supports Untied Overclocking Technology. Please read “Untied Overclocking Technology” on page 19 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 12 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® XP and Windows® VistaTM. For Windows® XP 64-bit and Windows® VistaTM 64bit 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 check Intel® website for the latest information.

6. Before installing SATAII hard disk to SATAII connector, please read the “SATAII Hard Disk Setup Guide” on page 23 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.

7. Power Management for USB 2.0 works fine under Microsoft® Windows VistaTM 64-bit / VistaTM / XP 64-bit / XP SP1 or SP2 / 2000 SP4.

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:

9. Featuring an advanced proprietary hardware and software design, Intelligent Energy Saver is a revolutionary technology that delivers unparalleled power savings. In other words, it is able to provide exceptional power saving and improve power efficiency without sacrificing computing performance.

10. 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.

11. 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.

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.

For the installation of Intel 775-LAND CPU, please follow the steps below.

775-Pin Socket Overview

Before you insert the 775-LAND CPU into the socket, please check if the CPU surface is unclean or if there is any bent pin on the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.

Step 1. Open the socket:

Step 1-1. Disengaging the lever by depressing

down and out on the hook to clear retention tab.

Step 1-2. Rotate the load lever to fully open po-

sition at approximately 135 degrees.

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

sition at approximately 100 degrees.

Step 2. Insert the 775-LAND CPU:

Step 2-1. Hold the CPU by the edges where are

marked with black lines.

Step 2-2. Orient the CPU with IHS (Integrated

Heat Sink) up. Locate Pin1 and the two orientation key notches.

For proper inserting, please ensure to match the two orientation key notches of the CPU with the two alignment keys of the socket.

Step 2-3. Carefully place the CPU into the socket

by using a purely vertical motion.

Step 2-4. Verify that the CPU is within the socket

and properly mated to the orient keys.

Step 3. Remove PnP Cap (Pick and Place Cap):

Use your left hand index finger and thumb to support the load plate edge, engage PnP cap with right hand thumb and peel the cap from the socket while pressing on center of PnP cap to assist in removal.

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 4. Close the socket:

Step 4-1. Rotate the load plate onto the IHS. Step 4-2. While pressing down lightly on load

plate, engage the load lever.

Step 4-3. Secure load lever with load plate tab

under retention tab of load lever.

G31M-VS motherboard provides two 240-pin DDR2 (Double Data Rate 2) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DDR2 DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single channel mode.

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

2. If you install only one memory module or two non-identical memory modules, it is unable to activate the Dual Channel Memory Technology.
