Installing and Configuring the NVIDIA nForce 650i Ultra Motherboard
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
