Parameter Spread Spectrum
Description When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus reducing EMI. This benefit may in some case be outweighed by problems with timing-critical devices, such as a clock-sensitive SCSI device. Enables or Disables HT Spread Spectrum. HT is Hyper Transport between CPU and North Bridge.

This feature controls the availability of the [Enabled], [Disabled] processors SSE and SSE2 instruction sets. When enabled, the processors SSE and SSE2 instruction sets are enabled. Software applications can make use of those instructions to better process large amounts of data quickly. When disabled, the processors SSE and SSE2 instruction sets are disabled. Software applications will not be able to use those instructions to process multiple data elements simultaneously. However, the processors MMX instruction set will still be available for use. It is highly recommended that you leave this BIOS feature at the default setting.

The following table describes the parameters found in this menu:
Auto Detect DIMM/PCI CLK Manufacturer CPU frequency Spread Spectrum
This option allows you to enable/disable the feature of auto detecting the clock frequency of the installed PCI bus. This item specifies CPU Manufacturer This item specifies CPU frequency When the motherboards clock generator pulses, the extreme values (spikes) of the pulses create 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, setting to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are overlooking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your over lock ed processor to lock up.
