Do you think that your Nspire is too slow? It was possible to boost it through an overclock with our Nover 2 tool.

Overclocking means increasing the chips frequency.
It has been used by Texas Instruments on TI-Nspire Clickpad/TouchPad, as the initial processor frequency was 90MHz and has been increased to 120MHz since OS version 2.1, giving a performance boost of 33,3%.

Nover was allowing you:

• to increase the processor frequency of your TI-Nspire ClickPad/TouchPad even more at 150MHz!
  
• to increase the processor frequency of your TI-Nspire CX/CM from 132 to 220-240MHz, giving a 66-82% performance boost!

On TI-Nspire ClickPad/TouchPad, it was really easy: you just had to put all frequencies to the maximum and it worked directly!

On TI-Nspire CX/CM, it was something else since the maximum processor frequency of 378MHz is unstable, and according to reviews and tests on different calculators, the maximum stable frequency is between 220 and 240MHz. You had thus to follow a tutorial in order to determine the highest stable frequency.



The new Nover 3 version tonight thus has great improvements - as you don't even need to follow the tutorial anymore, nor to know anything about overclocking.
And thus, Nover 3 seeks the best stable overclocking for your calculator by itself!
You just have to put it in the Ndless startup folder, reboot your calculator and after a few minutes the best overclock configuration is detected and saved !

The automated search follows the tutorial steps, using the safest seeking-way. Your calculator may reboot or freeze while doing the automated search, and it's normal since the program tests if the current configuration is stable. Those (two at least) crashes on TI-Nspire CX/CM happen in a non-critical code zone. When freezing, you only have to reboot the calculator and the process will go on.



Here you can see a TI-Nspire CM Chinese Edition EVT1 prototype, with Nover 3 boosting the frequency from 132 to 234MHz, meaning a 77.2% performance boost!
The installation process made only two freezes, thus needing 3 reboots before opting for the 234MHz.


Here are some statistics with the frequencies automatically set by Nover 3 installation on some TI-Nspire CX/CM I've gathered for you:

• 1^st, 234MHz: TI-Nspire CM Chinese Edition EVT1 prototype + TI-Nspire CX TA3 prototype + TI-Nspire CX CAS hardware revision F (july 2012)
  
• 2^nd, 228MHz: TI-Nspire CX CAS hardware revision D (september 2011)
  
• 3^rd, 222MHz: TI-Nspire CX CAS hardware revision D (september 2011) + TI-Nspire CX CAS hardware revision C (july 2011)
  
• 4^th, 210MHz: TI-Nspire CM-C CAS non-revised hardware (april 2012)

Feel free to complete those statistics by answering in the topic.

You can still mess with the settings if you want to as no feature has been removed.

If you don't want Nover 3 to automatically set the overclock, you just need to run it after sending it to the calculator and to set & store your own overclock.
Indeed, the automatic overclocking process is triggered on startup only if the config file is missing.

And even if Nover did set the overclock automatically, you can still modify the settings it chose (for example increasing/decreasing the base frequency by one step) by just running it.

I always have my calc running at 230-something MHz, never had issues.

Nice update critor

@Wayne -> On the emulator it will reach 378MHz, bon you won't really notice a boost in the performance.
But it works the other way - if you downclock the cpu it really runs slower

Is there a battery saver option? Bazinga

You can downclock to save battery, yes. But I have no statistics about that.

This has been tested on the B/W nspires?

Yes, but there is nothing new useful on B/W Nspires, as you can simply set all frequencies to the maximum on those models.

humm. very well. ty

Does AHB frequency affect performance?
Does base frequency affect performance?

Both do.

By the way, is 252MHz safe even if it doesn't reset?

More so than 69 MHz AHB, at least.
