Chapter 2 Installation
2-1 Before You Begin
Please take note of all precautions before you install anything on to the mainboard or change any of the mainboard settings.
Turn off the power to your system and discharge your body's static electric charge by touching a grounded surface—for example, the metal surface of the power supply—before performing any hardware procedure.
The manufacturer assumes no liability for any damage, caused directly or indirectly, by improper installation of any components by unauthorized service personnel. If you do not feel comfortable performing the installation, consult a qualified computer technician.
Damage to system components, the mainboard, and injury to you may result if power is applied during installation.
2-2 Installing the I/O Shield
The mainboard comes complete with an I/O shield. When installed in the chassis, the shield blocks radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the chassis.
Install the I/O shield before installing the mainboard in the chassis. Place the shield inside the chassis. Press the shield into place so that it fits tightly and securely. If the shield does not fit, obtain a properly sized shield from the chassis supplier.
2-3 Securing to the Chassis
When installing the mainboard, you have to secure the mainboard into the chassis by fastening with nine screws. Please refer to your chassis manual for instructions.
2-4 Installing the CPU and Cooler
Follow the steps below to install the CPU & cooler correctly.
-
Open the hinge lever (a) then fully open the active lever (b).
-
Open the load plate by pushing down on the hinge lever to raise the load plate and Grasp the tab.
-
Open load plate to fully open position.
-
Remove the protective socket cover from the socket. Do not touch the CPU socket contacts to avoid damaging.

Note:
Do not discard the protective socket cover. Be sure to always replace the cover unless the CPU is installed.

2-5 Installing System Memory
This mainboard has four 240-pin DIMM sockets for DDR3 memory. These slots support 1GB, 2GB, 4GB and 8GB DDR3 DIMMs up to max. 32GB
Make sure that you install memory modules of the same type and density in the different channel DIMM slots for Dual-Channel mode.
There must be at least one memory bank populated to ensure normal operation and you can insert the memory module into any of the DIMM slots.
Memory configurations
Use the following the recommendations for installing memory.
| Location\DIMM Quantity | 1 DIMM(Single Channel) | 2 DIMMs(Dual Channel) | 3 DIMMs(Triple Channel) | 4 DIMMs(Quad Channel) |
| DIMM#1 | V | V | V | V |
| DIMM#2 | -- | -- | V | V |
| DIMM#3 | -- | V | V | V |
| DIMM#4 | -- | -- | -- | V |
("V" = Memory installed, "--" = No memory installed)

Memory Installation
DDR3 and DDR2 memory modules are physically different. Please only install DDR3 DIMMs in this mainboard.
To install the DIMM, follow these steps:
-
Pull both clips on either side of the slot outwards. Align the DIMM module with the slot.
-
Press modules straight down until the plastic clips close and the module fits tightly into the DIMM slot. Push clips inwards to make sure they are in place and the memory is securely fitted.
2-6 Installing Expansion Cards
