170 Appendix
Advanced Displays processor type and current BIOS settings for processor clock speed,
processor multiplier, front side bus (FSB) clock, and CPU core voltage. These
settings may have been set by performance tuning applications or may change
depending on settings in performance applications that you have installed.
For systems with Intel Extreme processors, the following fields are adjustable
through the BIOS:
• Processor Clock Speed: Adjusts the multiplier of the processor. For processors
that cannot be overclocked, this field reports the current settings and cannot
be changed.
• Performance Application Support: Enables software applications to display
and modify key system parameters to tune system performance. These
applications are not installed or supported by Dell. The default is Off.
NOTE: To enable overclocking of other system components, you first need to
enable the Performance Application Support option in BIOS and then download
an application like NVIDIA nTune version 5.0 or higher.
NOTE: Pressing <Alt><F> returns your system to the factory defaults including
RAID settings.
