Nover 3: boost your Nspire with the automatic overclocker

critor

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!{:thumbsup:}
• to increase the processor frequency of your TI-Nspire CX/CM from 132 to 220-240MHz, giving a 66-82% performance boost!{:thumbsup:}
  

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

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!{:thumbsup:}
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 ! :D

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!{:thumbsup:}
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:

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

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

Well, that's great.
Before my CM's death, I have tried Nover2 on it, and I was shocked, it could boost to 246MHz and passed my stabilization test(play videos with Nspire Movie Player for an hour).

critor

Yeah, CM prototypes seem to overclock quite well. :)

And I'm also interested in HP Prime over clocking, as far as I know, S3C2416 could be boosted to 533MHz easily.

after the 2nd reset,my calculator has been locking on the "looking for best safe overclock..." for 10 minutes.
i wonder how i can know whether it's finished and  to press which button
this is my first time to use nover;)

You should reset your calculator manully in this case.

oh,sorry.i continued waiting,after 3rd reset ,it seems to be able to work.thanks for so wonderful app

and i want to ask for some suggestions for best stable config

im looking forward to nover3 for prime.

sorry for my  english.

Prime has not been cracked yet. But as it used a common processor, cracking should be much easlier than nspire {:smile:}

should i delete this software after my overclocking？

critor

You should not delete it if you want to keep the overclocking.

Indeed, the software will have to apply the overclock on each restart/reboot.

It worked on my cx well at first,but after i tried to overclock to 252mhz,it all ends up with a systemerror and reboot just doesn't work.I'm using ndless3.6.
