IBM G52-72361X2 manual Spread Spectrum, Adjust CPU FSB Frequency, Adjust PCI Express Frequency

BIOS Setup

Important

The settings shown in different color in CPU Voltage, DDR Voltage and NB Voltage help to verify if your setting is proper for your system.

[Gray]	Default setting.
[White]	Safe setting.
[Yellow]	High performance setting.
[Red]	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 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, 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 MSITM’s 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.
