Performance Tuning
System Setup Based Performance Tuning
For some Dell systems, the settings available under the Advanced page of
System Setup provide users with enhanced access to the options and controls
that allow for computer performance to be manually tuned.
NOTICE:
System Setup allows users unrestricted access when setting
performance related parameters. Improperly configuring these settings or choosing
options outside the capabilities of the installed components may cause system
instability, reduced component operating life or permanent component damage.
For more information on accessing System Setup, see "System Setup" on
page 307.
Software Based Performance Tuning
NVIDIA Enthusiast System Architecture (ESA) is a PC protocol for real-time
monitoring and control of computer’s thermal, electrical, acoustic and
operating characteristics.
If your computer includes components compatible with ESA, Dell has pre-
installed applications for monitoring and "tweaking" the performance of the
components.
For more information about ESA, see nvidia.com/object/nvidia_esa.html.
NVIDIA Performance
The NVIDIA Performance application integrates many of the functions
previously available in the NVIDIA nTune application into the Performance
section of the NVIDIA Control Panel.
NOTE:
When using the Performance section of the NVIDIA Control Panel, you may
be required to accept an End User License Agreement.
