Automatic Tuning 

 

The NVIDIA nTune performance manager uses a complex searching algorithm 
to determine the best possible and most stable performance for you system. 
The nTune tuning engine pushes your system to the limits to test the highest 
possible performance settings. Because of this, there may be instances of system 
hangs during the testing. When you restart the system, nTune continues its 
tuning process until the process is complete. It is highly recommended that you 
check the 

 box at the 

bottom of the Tune System screen. The effects of the tuning process apply to 
the current Windows session only. 
The nTune tuning engine runs internal benchmark tests on your system and 
creates performance profiles and rules.  
 

 
Three tuning options are available on the Tune System menu: 

‰ 

Course tuning takes approximately 20 minutes to run while it adjusts 
system bus speeds and parameters. It first saves current bus speeds as two 
profiles: the 

 file with current bus speeds and 

 with the highest passing settings. 

‰ 

Fine tuning takes approximately three (3) hours and performs a more 
complex tuning on bus speeds, memory timings, and voltages. This more 
complex testing achieves maximum performance.  

‰ 

Tuning using custom settings allows you to select specific areas to test 
and the duration of the tests. Remember that a longer tuning session results 
in more precise and stable settings. The progress of your test and the results 
upon completion are displayed when the benchmarks are being executed. 
You can cancel the tests at any time.
