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.This motherboard supports CPU power up to 65W. Please refer to CPU support list for compatible CPU. ASRock website: http://www.asrock.com
2.About the setting of “Hyper Threading Technology”, please check page 36.
3.This motherboard supports Untied Overclocking Technology. Please read “Untied Overclocking Technology” on page 24 for details.
4.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 16 for proper installation.
5.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.
6.The maximum shared memory size is defined by the chipset vendor and is subject to change. Please check Intel® website for the latest information.
7.Before installing SATAII hard disk to SATAII connector, please read the “SATAII Hard Disk Setup Guide” on page 23 to adjust your SATAII hard disk drive to SATAII mode. You can also connect SATA hard disk to SATAII connector directly.
8.Power Management for USB 2.0 works fine under Microsoft® Windows® VistaTM 64-bit / VistaTM / XP 64-bit / XP SP1 or SP2 / 2000 SP4.
9.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
10.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. Please visit our website for the operation procedures of Intelligent Energy Saver.
ASRock website: http://www.asrock.com

11.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 preparing 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.
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.

Chapter 2 Installation
G41M-VS is a Micro ATX form factor (8.8" x 6.7", 22.4 x 17.0 cm) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
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.
2.1 Screw Holes
Place screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-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.
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 antistatic pad or in the bag that comes with the component.
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.

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 position at approximately 135 degrees.
Step 1-3. Rotate the load plate to fully open position 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.

2.4Installation of CPU Fan and Heatsink
This motherboard is equipped with 775-Pin socket that supports Intel 775-LAND CPU. Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU to dissipate heat. Before you installed the heatsink, you need to spray thermal interface material between the CPU and the heatsink to improve heat dissipation. Ensure that the CPU and the heatsink are securely fastened and in good contact with each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see page 10, No. 3).
For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink.
Below is an example to illustrate the installation of the heatsink for 775-LAND 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 10, No. 3).
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.
