1. Please turn off the power and unplug the power cord before installing the CPU. 
2. Pull the lever sideways away from the socket.  Make sure to raise the lever up to a 
90-degree angle. 
3. Look for the gold arrow on the CPU. The CPU can only fit in the correct orientation. Lower 
the CPU down onto the socket. 
4. 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.    
5. 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. 
 Installing AMD Athlon64 CPU Cooler Set 
When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached 
on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your 
dealer to purchase and install them before turning on the computer.  
1. Detach the shield of the backplate’s paster. 
2. Turn over the mainboard, and install the backplate to the proper position. 
3. Turn over the mainboard again and place the mainboard on the flat surface. Locate the 
two screw holes of the mainboard. 
4. Align the retention mechanism and the backplate. Fix the retention mechanism and the 
backplate with two screws.

13 Cell Menu 
 
Current CPU/DDR Clock 
It shows the current clock of CPU/ DDR. Read-only. 
High Performance Mode 
This field allows you to select the DDR timing setting. Setting to [Optimized] enables Adjust DDR 
Memory Frequency automatically to be determined by SPD. Selecting [Manual] allows users to 
configure these fields manually. Setting options: [Optimized], [Manual]. 
Aggressive timing 
This item allows you to enable or disable the memory clock. When [Enabled] is selected, the 
timing delay of memory will be shorten to increase the performance. Setting options: [Enabled], 
[Disabled]. 
Dynamic OverClocking 
Dynamic Overclocking Technology is the automatic overclocking function, included in the MSITM
 
newly developed CoreCellTM Technology. It is designed to detect the load balance of CPU while 
running programs, and to adjust the best CPU frequency automatically. When the motherboard 
detects CPU is running programs, it will speed up CPU automatically to make the program run 
smoothly and faster. When the CPU is temporarily suspending or staying in the low load balance, 
it will restore the default settings instead. Usually the Dynamic Overclocking Technology will be 
powered only when users PC need to run huge amount of data like 3D games or the video 
process, and the CPU frequency need to be boosted up to enhance the overall performance. 
Setting options: 
[Disabled]  Disable Dynamic Overclocking. 
[Private]  1st level of overclocking, increasing the CPU frequency by 1%. 
[Sergeant]  2nd level of overclocking, increasing the CPU frequency by 3%. 
[Captain] 3rd level of overclocking, also the default value of Load High Performance 
Defaults, increasing the CPU frequency by 5%.  
						

							 
14  [Colonel]  4th level of overclocking, increasing the CPU frequency by 7%. 
[General]  5th level of overclocking, increasing the CPU frequency by 10%. 
[Commander] 6th level of overclocking, increasing the CPU frequency by 15%. MSI Reminds You...  Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. We suggest user to make sure that your CPU can afford to overclocking regularly first. If you find the PC appears to be unstable or reboot incidentally, its better to disable the Dynamic Overclocking or to lower the level of overclocking options. By the way, if you need to conduct overclocking manually, you also need to disable the Dynamic OverClocking first.  
Spread Spectrum 
When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses 
creates 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. 
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, set to Enabled for EMI reduction. 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. 
HT Frequency 
This setting specifies the maximum operating frequency of the link transmitter clock. Setting 
options: [1x], [2x], [3x], [4x], [5x]. 
Cool’n’Quiet 
It provides a CPU temperature detecting function to prevent your CPU’s from overheading due to 
the heavy working loading. 
Adjust CPU Ratio 
This item lets you adjust the CPU ratio. Setting to [Startup] enables the CPU running at the 
fastest speed which is detected by system. Setting options are: [Startup], [x4]~[x25]. 
Adjust CPU FSB Frequency 
This item allows you to select the CPU Front Side Bus clock frequency (in MHz). Select the 
number between [200]~[300] for needed frequency. 
Adjust AGP Frequency 
This item allows you to select the AGP frequency (in MHz). Select the number between 
[66]~[100] for needed frequency. 
CPU Voltage 
This feature allows you to trim the voltage of CPU.  
Memory Voltage 
Adjusting the DDR voltage can increase the DDR speed. Any changes made to this setting may 
cause a stability issue, so changing the DDR voltage for long-term purpose is NOT 
recommended. 
AGP Voltage 
AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP 
display card when overclocking, but the stability may be affected.
