Installing the heatsink and fan
The AMD Athlon 64/AMD Athlon 64 FX/AMD Athlon 64 X2 and AMD Sempron processors require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
Make sure that you use only AMD-certified heatsink and fan assembly.
To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base.
The retention module base is already installed on the motherboard upon purchase. You do not have to remove the retention module base when installing the CPU or installing other motherboard components. If you purchased a separate CPU heatsink and fan assembly, make sure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.
CPU fan CPU heatsink Retention module base
Retention bracket Retention bracket lock
Your boxed CPU heatsink and fan assembly should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter.
Attach one end of the retention bracket to the retention module base.
Align the other end of the retention bracket (near the retention bracket lock) to the retention module base. A clicking sound denotes that the retention bracket is in place.
Make sure that the fan and heatsink assembly perfectly fits the retention mechanism module base, otherwise you cannot snap the retention bracket in place.
Push down the retention bracket lock on the retention mechanism to secure the heatsink and fan to the module base.
When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.
GND CPU FAN PWR CPU FAN IN CPU FAN PWM
M2N/M2N DH CPU Fan Connector Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. This connector is backward compatible to the 3-pin CPU fan connector. Only 4-pin CPU fan supports Q-Fan function.

For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum power of 600 W. Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will not boot. Use of a PSU with a higher power output is recommended when configuring a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.

If you are using Windows XP: 1. Click the Start button then select Turn Off Computer. 2. Click the Turn Off button to shut down the computer. 3. The power supply should turn off after Windows shuts down.
Using the dual function power switch
While the system is ON, pressing the power switch for less than four seconds puts the system to sleep mode or to soft-off mode, depending on the BIOS setting. Pressing the power switch for more than four seconds lets the system enter the soft-off mode regardless of the BIOS setting. Refer to section 4.5 Power Menu in Chapter 4 for details.
This chapter tells how to change the system settings through the BIOS Setup menus. Detailed descriptions of the BIOS parameters are also provided.
