Hyper-Threading Technology  
The processor uses Hyper-Threading technology to increase transaction rates  
and reduces end-user response times. The technology treats the two cores  
inside the processor as two logical processors that can execute instructions  
simultaneously. In this way, the system performance is highly improved. If you  
disable the function, the processor will use only one core to execute the  
instructions. Please disable this item if your operating system doesnt sup-  
port HT Function, or unreliability and instability may occur.

PCI/PNP Resource Management  
This section describes configuring the PCI bus system and PnP (Plug & Play) feature.  
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to  
operate at speeds nearing the speed the CPU itself uses when communicating with  
its special components. This section covers some very technical items and it is  
strongly recommended that only experienced users should make any changes to the  
default settings.  
Clear NVRAM  
The NVRAM (Non-volatile Random Access Memory) is where the BIOS stores re-  
source information for both PNP and non-PNP devices in a bit string format. When the  
item is set to [Yes], the system will reset NVRAM right after the system is booted up  
and then set the setting of the item back to [No] automatically.  
Plug & Play O/S

Not recommended setting and the system may be  
unstable.  
Changing CPU Voltage, DDR Voltage and NB Voltage may result in the  
instability of the system; therefore, it is NOT recommended to change  
the default setting for long-term usage.  
Spread Spectrum  
When the motherboards 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,  
select the desired range for EMI reduction. Remember to disable Spread Spectrum  
function if you are overclocking, because even a slight jitter can introduce a tempo-  
rary boost in clock speed which may just cause your overclocked processor to lock  
up.  
Adjust CPU FSB Frequency  
This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and  
overclock the processor by adjusting the FSB clock to a higher frequency. Setting  
options: For CPU FSB200: [200]~[500]  
Adjust PCI Express Frequency  
This item allows you to select the PCI Express frequency (in MHz). Select the number  
between [100]~[133] for needed frequency.  
CPU Dynamic OverClocking  
Dynamic Overclocking Technology is the automatic overclocking function, included in  
the MSITMs 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.

Important  
1. 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 overclock regularly first. If you  
find the PC appears to be unstable or reboot incidentally, it's 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.  
2. Meanwhile, there are two functions to protect user's system from  
crashing.  
- There is a safe key "Ins" in BIOS. In case the overclocking fails, you can  
press "Ins" key while system rebooting to restore to the BIOS defaults.  
- If the system incidentally reboot for four times, the BIOS will also be  
restored to the defaults.  
Auto Disable PCI Clock  
This item is used to auto detect the PCI slots. When set to [Enabled], the system will  
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interfer-  
ence (EMI). Settings: [Enabled], [Disabled].  
Adjust PCI Frequency  
This item allows you to select the PCI frequency (in MHz). In default this value will  
change automatically in accordance with the setting of Adjust CPU FSB Frequency.  
However, you may adjust the desired fixed PCI frequency you like by using the <+> &  
<-> key. Setting option: [33.3].
