ASUS Q-Fan
ASUS Q-Fan technology intelligently adjusts the CPU fan speed according to system loading to ensure a quiet, cool, and efficient operation.
Core Unlocker
ASUS Core Unlocker simplifies the activation of a latent AMD® CPU— with just a simple switch. Enjoy an instant performance boost by simply unlocking the extra cores, without performing complicated BIOS changes.
The actual overclocking result depends on the system configuration.
ASUS Anti-Surge Protection
This special design prevents expensive devices and the motherboard from damage caused by power surges from switching power supply (PSU).
ASUS EPU
ASUS EPU is a unique power saving technology that detects the current system loadings and adjusts the power consumption in real time.
ASUS M4N68T-M Series |
1-3 |
ASUS AI NET2
ASUS AI NET2 remotely detects the cable connection immediately after you turn on the system and any faulty cable connections are reported back up to 100 meters at 1 meter accuracy.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction on the use of Hazardous Substances (RoHS).

Chapter 1: Product introduction |
1.4Before 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, switch off the ATX power supply and detach its power cord. Failure to do so may cause severe damage to the motherboard, peripherals, or components.
Onboard 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.

1.6Central Processing Unit (CPU)
This motherboard supports AMD® Phenom™ II / Athlon™ II / Sempron™ 100 series processors.
The AM3 socket has a different pinout from the the AM2+/AM2 socket. Ensure that you use a CPU designed for the AM3 socket.
1.6.1Installing the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.

2. |
Press the lever sideways to unlock the |

|
socket, then lift it up to a 90°-100° angle. |
|
Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the CPU will not fit in completely.
3.Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle.
4. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation.
DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!

5.When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.
6. Install a CPU heatsink and fan following the instructions that comes with the heatsink package. You can also refer to section 1.6.2 Installing heatsink and fan for instructions.
7.Connect the CPU fan cable to the CPU_FAN connector on the motherboard.

1.6.2Installing the heatsink and fan
Ensure 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, ensuring 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, ensure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.

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.
2.Attach one end of the retention bracket to the retention module base.
