[Disabled] Disable Dynamic Overclocking. [Private] 1st level of overclocking. [Sergeant] 2nd level of overclocking. [Captain] 3rd level of overclocking, also default of Load High Performance Defaults. [Colonel] 4th level of overclocking. [General] 5th level of overclocking. [Commander] 6th level of overclocking. Performance Mode Allows you to control the MAT (memory acceleration technology) function of CPU. MAT is MSITM exclusive technology, specialized in optimizing the data transfer rate among CPU, N/B chip and memory, and also in procuring better memory performance and bandwidth up to 10%. Selecting [Fast] enables MAT. Note that not every memory is compatible with MAT. If the system fail to reboot for four times, the BIOS will be restored to the Default value ([Normal]). Setting options: [Normal], [Fast]. CPU Ratio Selection This setting controls the multiplier that is used to determine the internal clock speed of the processor relative to the external or motherboard clock speed. DRAM Frequency Use this field to configure the clock frequency of the installed DRAM. Settings are: PSB 400: [100-355MHz] PSB 533: [133-500MHz] PSB 800: [200-500MHz] Spread Spectrum When the motherboard 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, activate the Spread Spectrum 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. Options: [Disabled], [Enabled]. Adjust CPU Bus Clock (Mhz) This item allows you to select the CPU Bus clock frequency (in MHz) and overclock the processor by adjusting the FSB clock to a higher frequency. Also the setting you choose will change color for warning if the value is of over the specifications. DDR Clock (Mhz) This read-only item allows you to view the current DDR clock. 13

[Disabled]
Disable Dynamic Overclocking.
[Private]
1st level of overclocking.
[Sergeant]
2nd level of overclocking.
[Captain]
3rd level of overclocking, also default of Load High Performance Defaults.
[Colonel]
4th level of overclocking.
[General]
5th level of overclocking.
[Commander]
6th level of overclocking.
Performance Mode
Allows you to control the MAT (memory acceleration technology) function of CPU. MAT is MSITM
exclusive technology, specialized in optimizing the data transfer rate among CPU, N/B chip and
memory, and also in procuring better memory performance and bandwidth up to 10%. Selecting [Fast]
enables MAT. Note that not every memory is compatible with MAT. If the system fail to reboot for four
times, the BIOS will be restored to the Default value ([Normal]). Setting options: [Normal], [Fast].
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock speed of the processor
relative to the external or motherboard clock speed.
DRAM Frequency
Use this field to configure the clock frequency of the installed DRAM. Settings are:
PSB 400:
[100-355MHz]
PSB 533:
[133-500MHz]
PSB 800:
[200-500MHz]
Spread Spectrum
When the motherboard
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, activate the Spread Spectrum 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. Options: [Disabled],
[Enabled].

This item allows you to select the CPU Bus clock frequency (in MHz) and overclock the processor by
adjusting the FSB clock to a higher frequency. Also the setting you choose will change color for
