HARDWARE SETUP

This chapter provides you with information about hardware setup procedures. While doing the installation, be careful in holding the components and follow the installation procedures. For some components, if you install them in the wrong orientation, they will not work properly. Use a grounded wrist strap before handling computer components. Static electricity may damage the components.

CPU & Cooler Installation for AM3

When you are installing the CPU, make sure the CPU has a cooler attached on the top to prevent overheating. Meanwhile, do not forget to apply some thermal paste on the CPU before installing the heat sink/cooler fan for better heat dispersion.

Follow the steps below to install the CPU & cooler correctly. Wrong installation will cause the damage of your CPU & mainboard.

1. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-degree angle.
2. Look for the gold arrow of the CPU. The gold arrow should point as shown in the picture. The CPU can only fit in the correct orientation.
3. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.
4. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.
5. Position the cooling set onto the retention mechanism. Hook one end of the clip to hook first.
6. Then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism. Locate the Fix Lever and lift up it.
7. Fasten down the lever.
8. Attach the CPU Fan cable to the CPU fan connector on the mainboard.

IMPORTANT

* Mainboard photos shown in this section are for demonstration only. The appearance of your mainboard may vary depending on the model you purchase. * While disconnecting the Safety Hook from the fixed bolt, it is necessary to keep an eye on your fingers, because once the Safety Hook is disconnected from the fixed bolt, the fixed lever will spring back instantly.

Installing Memory Modules

1. The memory module has only one notch on the center and will only fit in the right orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.

IMPORTANT

* DDR3 memory modules are not interchangeable with DDR2 and the DDR3 standard is not backwards compatible. You should always install DDR3 memory modules in the DDR3 DIMM slots. * In Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots. * To enable successful system boot-up, always insert the memory modules into the DIMM1 first.

Spread Spectrum

When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves.

IMPORTANT

* If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and performance. But if you are plagued by EMI, select the value of Spread Spectrum for EMI reduction. * The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system will become less stable. For the most suitable Spread Spectrum value, please consult your local EMI regulation. * Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up.

Load Optimized Defaults

You can load the default values provided by the mainboard manufacturer for stable performance.
