Safety information  
Electrical safety  
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet  
before relocating the system.  
When adding or removing devices to or from the system, ensure that the power cables  
for the devices are unplugged before the signal cables are connected. If possible,  
disconnect all power cables from the existing system before you add a device.  
Before connecting or removing signal cables from the motherboard, ensure that all  
power cables are unplugged.  
Seek professional assistance before using an adapter or extension cord. These devices  
could interrupt the grounding circuit.  
Ensure that your power supply is set to the correct voltage in your area. If you are not  
sure about the voltage of the electrical outlet you are using, contact your local power  
company.  
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service  
technician or your retailer.  
Operation safety  
Before installing the motherboard and adding devices on it, carefully read all the manuals  
that came with the package.  
Before using the product, ensure all cables are correctly connected and the power  
cables are not damaged. If you detect any damage, contact your dealer immediately.  
To avoid short circuits, keep paper clips, screws, and staples away from connectors,  
slots, sockets and circuitry.  
Avoid dust, humidity, and temperature extremes. Do not place the product in any area  
where it may become wet.  
Place the product on a stable surface.  
If you encounter technical problems with the product, contact a qualified service  
technician or your retailer.

Product introduction

1.1  
Before you proceed  
Take note of the following precautions before you install motherboard components or change  
any motherboard settings.  
Unplug the power cord from the wall socket before touching any component.  
Before handling components, use a grounded wrist strap or touch a safely grounded  
object or a metal object, such as the power supply case, to avoid damaging them due  
to static electricity.  
Hold components by the edges to avoid touching the ICs on them.  
Whenever you uninstall any component, place it on a grounded antistatic pad or in the  
bag that came with the component.  
Before you install or remove any component, ensure that the ATX power supply 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, or components.  
Standby Power LED  
The motherboard comes with a standby power LED that lights up to indicate that the system  
is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down  
the system and unplug the power cable before removing or plugging in any motherboard  
component. The illustration below shows the location of the onboard LED.

Motherboard overview  
Before you install the motherboard, study the configuration of your chassis to ensure that the  
motherboard fits into it.  
Ensure that you unplug the power cord before installing or removing the motherboard.  
Failure to do so can cause you physical injury and damage motherboard components.  
C8HM70-I Series motherboards include C8HM70-I and C8HM70-I/HDMI models. The  
package contents vary from models. The layout illustrations in this user guide are for  
C8HM70-I/HDMI only.  
1.2.1  
Placement direction  
When installing the motherboard, ensure that you place it into the chassis in the correct  
orientation. The edge with external ports goes to the rear part of the chassis as indicated in  
the image below.  
1.2.2  
Screw holes  
Place four screws into the holes indicated by circles to secure the motherboard to the  
chassis.  
Do not overtighten the screws! Doing so can damage the motherboard.  
Place this side towards  
the rear of the chassis

Overview  
1.4.1  
This motherboard comes with two Double Data Rate 3 (DDR3) Small Outline Dual Inline  
Memory Modules (SO-DIMM) sockets. The figure illustrates the location of the DDR3 DIMM  
sockets:

C8HM70-I/HDMI 204-pin DDR3 DIMM sockets  
1.4.2  
Memory configurations  
You may install 512MB, 1GB, 2GB, 4GB and 8GB unbuffered non-ECC DDR3 SO-DIMMs  
into the DIMM sockets.  
Always install DIMMs with the same CAS latency. For optimum compatibility, it is  
recommended that you obtain memory modules from the same vendor.  
Due to the CPU limitation, when you install 4GB or more memory on the motherboard,  
the actual usable memory for the OS can be about 3GB or less. For effective use of  
memory, we recommend that you use a maximum of 3GB system memory.  
This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or  
less.

Expansion slots  
In the future, you may need to install expansion cards. The following sub-sections describe  
the slots and the expansion cards that they support.  
Unplug the power cord before adding or removing expansion cards. Failure to do so may  
cause you physical injury and damage motherboard components.  
1.5.1  
Installing an expansion card  
To install an expansion card:  
1.  
Before installing the expansion card, read the documentation that came with it and  
make the necessary hardware settings for the card.  
2.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw for later  
use.  
4.  
Align the card connector with the slot and press firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.5.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card.  
Install the software drivers for the expansion card.  
1.5.3  
PCI Express x16 slot  
This motherboard has a PCI Express 2.0 x16 slot (at 16x mode) that supports PCI Express  
2.0 x16 graphic cards complying with the PCI Express specifications.

Jumpers  
Clear RTC RAM (3-pin CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can  
clear the CMOS memory of date, time, and system setup parameters by erasing  
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in  
CMOS, which include system setup information such as system passwords.

Normal  
Clear RTC  
C8HM70-I/HDMI  
(Default)  
C8HM70-I/HDMI Clear RTC RAM  
To erase the RTC RAM:  
1.  
2.  
Turn OFF the computer and unplug the power cord.  
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3  
for about 5-10 seconds, then move the cap back to pins 1-2.  
3.  
4.  
Plug the power cord and turn ON the computer.  
Hold down the <Del> key during the boot process and enter BIOS setup to re-  
enter data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
If the steps above do not help, remove the onboard battery and move the jumper  
again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the  
battery.  
You do not need to clear the RTC when the system hangs due to overclocking. For  
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature.  
Shut down and reboot the system, then the BIOS automatically resets parameter  
settings to default values.
