Parameter Spread Spectrum HT Spread Spectrum SSE/SSE2 Instructions Description Options When the system clock generator pulses, [Enabled], [Disabled] 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. [Enabled], [Disabled] HT is Hyper Transport between CPU and North Bridge. This feature controls the availability of the [Enabled], [Disabled] processor's SSE and SSE2 instruction sets. When enabled, the processor's 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 processor's 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 processor's MMX instruction set will still be available for use. It is highly recommended that you leave this BIOS feature at the default setting. 32
