HARDWARE SETUP

CPU & Cooler Installation for AM3

When installing the CPU, make sure the CPU has a cooler attached on 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.

The surface of the AM3 CPU.

Remember to apply some thermal paste on it for better heat dispersion.

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

When set to [Auto], the system automatically determines the HT link speed.

Adjusted HT Link Frequency (MHz)

This item allows you to set the frequency of the memory and PCI. Only for advanced users.

Auto Disable DRAM/PCI Frequency

When set to [Enabled], the system will disable unused memory and PCI frequencies, which will lead to a reduction in electromagnetic interference (EMI).

CPU Voltage (V)/ CPU-NB Voltage (V)/ DRAM Voltage (V)

This item allows you to adjust the voltage of the CPU, memory, and chipset.

Spread Spectrum

Since the system's clock generator generates pulses, its operation can cause electromagnetic interference - EMI (Electromagnetic Interference). The Spread Spectrum function reduces this interference by modulating the generated pulses. If you do not have problems with interference, leave the value [Disabled] (disabled) for better stability and performance. However, if you encounter electromagnetic interference, you can try using this function by setting it to [Enable] (enabled). Do not forget to disable the Spread Spectrum function if you overclock the system board. This is necessary because even a slight fluctuation in the clock generator can cause the overclocked processor to fail.

WARNING

• If you do not have problems with interference, leave the value [Disabled] (disabled) for better stability and performance. However, if you encounter electromagnetic interference, select Spread Spectrum to reduce it. * The higher the Spread Spectrum value, the lower the level of electromagnetic interference, but the system will become less stable. To choose the appropriate Spread Spectrum value, refer to the levels of electromagnetic interference set by legislation.
• Do not forget to disable the Spread Spectrum function if you overclock the system board. This is necessary because even a slight fluctuation in the clock generator can cause the overclocked processor to fail.

Setting Default Values

You can load the default settings for the system, which are set by the motherboard manufacturer.
