Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
• Choose a chassis big enough to install this mainboard.
• As some features for this mainboard are implemented by cabling connectors on the
mainboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.
• If there is possibility of adopting some more hard drives, make sure your chassis has
sufcient power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port conguration of this mainboard. You can nd
an I/O shield specically designed for this mainboard in its package.
2.2 Installing Mainboard
Most computer chassis have a base with many mounting holes to allow the mainboard to
be securely attached, and at the same time, prevent the system from short circuits. There
are two ways to attach the mainboard to the
chassis base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is with
studs. Only if you are unable to do this should you
attach the board with spacers. Line up the holes on
the board with the mounting holes on the chassis.
If the holes line up and there are screw holes, you
can attach the board with studs. If the holes line
up and there are only slots, you can only attach with
spacers. Take the tip of the spacers and insert them
into the slots. After doing this to all the slots, you can slide the board into position aligned
with slots. After the board has been positioned, check to make sure everything is OK before
putting the chassis back on.
To install this mainboard:
1. Locate all the screw holes on the mainboard and the chassis base.
2. Place all the studs or spacers needed on the chassis base and have them tightened.
3. Face the mainboard’s I/O ports toward the chassis’s rear panel.
4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.
5. Install the mainboard with screws and have them tightened.
The mainboard and its component layouts illustrated in this chapter were
based mainly on model “G82UM-PVHD+”, unless specically stated.
Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to do so may cause severe damage to your
mainboard and/or peripherals. Plug in the AC power cord only after you have carefully
checked everything.
To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are
already fastened on the chassis base and are without mounting-holes on the mainboard to
align with.

2.3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the mainboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of heat sink paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specications. It is not
recommended that the system bus frequency be set beyond hardware specications since
it does not meet the required standards for the peripherals. If you wish to set the frequen-
cy beyond the proper specications, please do so according to your hardware
specications including the CPU, graphics card, memory, hard drive, etc.
2.3.1 Installation of the CPU
1. Unlock the socket by pressing the
lever sideways, then lift it up to a 90
o
.
2. Position the CPU above the socket such
that the CPU corner with the gold
triangle matches the socket corner with
a small triangle.
3. Carefully insert the CPU into the socket
until it ts place.
4. When the CPU is in place, push down
the socket lever to secure the CPU.
The lever clicks on the side tab to
indicate that it is locked.

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
2.4 Installation of Memory Modules
This mainboard provides four 240-pin DDRII (Double Data Rate) DIMM slots, (G81UM-MKII/
G81UM-PV+ provides two 240pin DDRII DIMM slots) and supports Dual Channel Memory
Technology. For dual channel conguration, you always need to install two identical (the
same brand, speed, size and chip-type) memory modules in the DDRII DIMM slots to activate
Dual Channel Memory Technology. Otherwise, it will operate at single channel mode.
To reach the performance of Dual Channel DDR2, the following rules must be obeyed:
For 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [DDR1]+[DDR2], or slots
[DDR3]+[DDR4] .
For 4-DIMM dual-channel installation:
Populate 2 DIMM modules of the same type and size on slots [DDR1]+[DDR2], and
another 2 DIMM modules of the same type and size on slots [DDR3]+[DDR4] .
[DDR1] and [DDR2] slots are made of the same color.
[DDR3] and [DDR4] are made of another same color.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only ts in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static
electricity by touching a grounded metal object briey.

Chapter 3 Jumpers & Headers Setup
3.1 Checking Jumper Settings
• For a 2-pin jumper, plug the jumper cap on both
pins will make it CLOSE (SHORT). Remove the
jumper cap, or plug it on either pin (reserved for
future use) will leave it at OPEN position.
• For 3-pin jumper, pin 1~2 or pin 2~3 can be
shorted by plugging the jumper cap in.
How to identify the PIN1 jumpers?
Please check the mainboard carefully, the PIN1
is marked by "1" or white thick line.
3.2 CMOS Memory Clearing Header
The time to clear the CMOS memory occurs when (a)
the CMOS data becomes corrupted, (b) you forgot
the supervisor or user password preset in the BIOS
menu, (c) you are unable to boot-up the system
because the CPU ratio/clock was incorrectly set in the
BIOS menu, or (d) whenever there is modication on
the CPU or memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it recongured to the default
values stored in BIOS.
• Pins 1 and 2 shorted
(Default): Normal
operation.
• Pins 2 and 3 shorted:
Clear CMOS memory.
To clear the CMOS memory and load in the default values:
1. Power off the system.
2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper
cap back to its default settings --- pin 1 and pin 2 shorted.
3. Power on the system.
4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS
setup menu right after powering on system.
