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 third-
party 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
of “User Manual” in the support CD.
3. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 19 for details.
4. This motherboard supportsDual 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.
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 64-
bit 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 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.
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.

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 prepar-
ing 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.

Pre-installation Precautions
Take note of the following precautions before you install mother-
board 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.

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.

2.3 Installation of Memory Modules (DIMM)
G41M-VS motherboard provides two 240-pinDDR2 (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 theDDR2DIMM slots to activateDual 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.

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and theDIMM if you force theDIMM into the
slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully
snap back in place and theDIMM is properly seated.

2.5 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.

PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.2 No. 1) +5VSB (standby) for PS/2
or USB wake up events.
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
ClearCMOS
(CLRCMOS1, 2-pin jumper)
(see p.2 No. 15)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. 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 2 pins on
CLRCMOS1 for 5 seconds.

EUP LAN/ EUPAudio Jumper
(EUP_LAN1,3-pin jumper, see p.2No.20)
(EUP_AUDIO1,3-pinjumper, see p.2 No.19)
Note: EUP_LAN and EUP_AUDIO jumper design decreases the power consumption
of this motherboard to meet EuP standard. With an ASRock EuP ready
motherboard and a power supply that the 5VSB power efficiency is higher
than 50% under 100mA current consumption, your system is able to submit
EuP standard. The default setting (short pin1 and pin2) is EuP enabled. If you
want to disable this power saving function, you may short pin2 and pin3.
Please be noticed that when EUP_LAN jumper is set to enabled, the
Wake-On-LAN function under S3 (Suspend to RAM), S4 (Suspend to Disk),
and S5 (Soft Off) will be disabled.

This motherboard supports Untied Overclocking Technology, which means during
overclocking, FSB enjoys better margin due to fixed PCI / PCIE buses. Before you
enable Untied Overclocking function, please enter “Overclock Mode” option of BIOS
setup to set the selection from [Auto] to [Manual]. Therefore, CPU FSB is untied
during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can
operate under a more stable overclocking environment.
