Spread

When the system clock generator pulses,

[Enabled], [Disabled]

Spectrum

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.

 

 

 

 

HT Spread

Enables or Disables HT Spread Spectrum.

[Enabled], [Disabled]

This feature controls the availability of the

[Enabled], [Disabled]

Instructions

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.
