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 Select to continue the tuning process upon reboot 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.
CAUTION: Make sure to save and close all work prior to running the Tune
System function. Close all applications and do not perform other tasks
during the tuning session.
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 Default.npe file with current bus speeds
and Bestsystem.npe 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
