Parameter Description Options
Spread
Spectrum
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.

HT Spread
Spectrum
Enables or Disables HT Spread Spectrum.
HT is Hyper Transport between CPU and
North Bridge.
[Enabled], [Disabled]
SSE/SSE2
Instructions
This feature controls the availability of the
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.
