Nover 3: Accélère ta Nspire avec l'overclock auto pour tous

[critor]

Tu trouves que ta TI-Nspire est trop lente? Il était déjà possible de lui redonner une seconde jeunesse en l'overclockant avec notre outil Nover 2.

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

L'overclocking consiste à augmenter la fréquence de fonctionnement de composants électroniques.
Il a d'ailleurs été utilisé par Texas Instruments sur les TI-Nspire ClickPad/TouchPad, la fréquence de fonctionnement du processeur qui était initialement de 90MHz est en effet passée à 120MHz à partir de la version 2.1 du système, soit un gain en performances de 33,3%.

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 te permettait:

• d'augmenter la fréquence de ton processeur TI-Nspire ClickPad/TouchPad encore plus loin jusqu'à 150MHz!
• d'augmenter la fréquence de ton processeur TI-Nspire CX/CM de 132 à 220-240MHz, et donc de gagner 66-82% en performances!

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!

Sur TI-Nspire ClickPad/TouchPad, c'était donc ultra simple: il suffisait de régler les fréquences au maximum et ça marchait!

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

Sur TI-Nspire CX/CM, c'est une autre histoire puisque la fréquence processeur maximale de 378MHz n'est pas stable, et que la fréquence stable maximale varie d'une machine à l'autre, usuellement entre 220 et 240MHz. Il fallait donc suivre une procédure de recherche afin de déterminer cette fréquence.

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.

La nouvelle version Nover 3 publiée ce soir améliore grandement ce dernier point et est désormais destinée à tous, même ceux qui n'ont aucune connaissance en overclocking.
En effet, elle recherche elle-même, la meilleure configuration d'overclock stable pour votre calculatrice!
Il suffit de l'enregistrer dans le dossier de démarrage de Ndless, de redémarrer la calculatrice et en seulement quelques minutes la configuration d'overclock optimale sera détectée et enregistrée!

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 !

La recherche automatisée suit en gros la procédure du tutoriel, utilisant donc un chemin d'exploration sûr. Il se peut que la calculatrice redémarre ou se bloque pendant cette recherche, et c'est normal puisque le programme se doit de tester la stabilité des configurations-candidates. Ces plantages, qui seront au moins deux sur TI-Nspire CX/CM, ont été confinés à une zone non critique du code. En cas de blocage, il suffit simplement de redémarrer la calculatrice et la procédure continuera automatiquement.

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.

Voici par exemple un prototype TI-Nspire CM Chinese Edition EVT1, que Nover 3 fait passer de 132 à 234MHz, soit un gain de 77,2%!
L'installation a généré ici seulement deux blocages, et a donc nécessité trois redémarrages avant d'opter pour le 234MHz.

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.

Voici un petit échantillon de calculatrices TI-Nspire CX/CM réunis pour vous donner une idée. Après installations de Nover 3, voici les résultats:

• 1^ères, 234MHz: prototype TI-Nspire CM Chinese Edition EVT1 + prototype TI-Nspire CX TA3 + TI-Nspire CX CAS révision matérielle F (juillet 2012)
• 2^nde, 228MHz: TI-Nspire CX CAS révision matérielle D (septembre 2011)
• 3^èmes, 222MHz: TI-Nspire CX CAS révision matérielle D (septembre 2011) + TI-Nspire CX CAS révision matérielle C (juillet 2011)
• 4^ème, 210MHz: TI-Nspire CM-C CAS matériel non révisé (avril 2012)

N'hésitez pas à compléter ces statistiques en répondant à l'article.

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)

Nover 3, ou l'overclocking automatisé pour tous

Nover 3, or the overclock automate for everyone

[Laurae]

Traduit en anglais

Un stress-test de quelques minutes c'est suffisant pour déterminer la stabilité sur Nspire ? (sachant que sur un ordi c'est pas le cas)

[critor]

J'avais un stress-test au départ, et puis je l'ai retiré car il ne fait jamais planter la TI-Nspire CX/CM, en tous cas pas dans la zone 220-240MHz.
Quand la calculatrice plante sur un overclock, c'est à froid et en lien avec des choses extérieures au programme Nover:
- si les interruptions sont activées et qu'il y a relâchement du processeur avec sleep
- immédiatement à la fin du programme Ndless ou quelques secondes après

Je ne sais pas ce qui nous empêche d'aller au-delà, mais ce n'est clairement pas le processeur.
Je procède donc de façon totalement différente pour détecter les instabilités, avec plusieurs tests de 'cool-down'.

[Handers]

234 MHz pour moi, sur une cx cas

P-0312D --> model de production, révision matérielle D produite en mars 2012 ?


Par contre 234 MHz c'est sur c'est bien pour de gros calculs mais le pendant c'est que l'AHB n'est plus qu' 58 MHz...

The short story is I bricked my calculator from trying this out and I'm hoping for some help.

The long story is I used this nover to replace the other nover 3 that I had working at safe levels.
After that I restarted, waited a little bit for the new nover to do something.
when nothing happened I entered my zlock passcode and opened the nover file directly.
The settings were as I left them so I raised them to just before nover told me they were dangerous.
I pressed var, enter, and the other option. after I realized my calculator froze I restarted and was taken to a white screen.
I tried restarting a few more times all with the same result, having "pp1234" in the top left corner (what does that mean?) as usual.
during this I also had 3.1 / 3.6 switch installed (on 3.1 at the time)
I'm using a ti-nspire cx cas and last I checked I'm on Boot1 3.0.0.99, Boot2 3.1.0.16
I haven't messed with the Boots at all

I've tried every number combination in maintenance mode and every time i try to install os 3.1 or even 3.2.0.1212 (to then downgrade back) I get the same error "[M7] You cannnot install a version of the OS that is older than the currently installed version."

Please Help!

[Lionel Debroux]

Check the boot2 version that your calculator is now running, through the Nspire computer software or TILP.
* if your calculator still has boot2 3.1.0.16, just reinstall nLaunchy (it is in the switcher pack), which doesn't care about the anti-downgrade protection.
* if your calculator has 3.2.4.7, then it means that you somehow transferred a recent OS the wrong way, in such a way that the anti-downgrade protection was raised... and you're toast (lest you reflash the boot2 through the RS232 port using extra, if cheap, equipment).

The fact that the anti-downgrade protection was raised is not a direct or indirect effect of Nover.

Modern versions of Nlaunchy overclock the processor when one of the OS 3.2 or 3.6 versions is detected, but that doesn't occur for OS 3.1.

Thanks for the help! I was able to check and I am still on 31016
Whenever I try to 'install os' nlaunch.tcc that I found in the switchpack file, the progress bar gets halfway before i get this error from ComputerLink "Ecperienced a problem while communicating with the handheld. A retry may be successful." and the calculator disconnects from computerlink and instantly goes back to the 'os not found' screen.
A retry has never been successful so far

[critor]

The installation is partially random, and the tutorial tells to retry if it didn't work.

But before retrying, check that the required files are still present in the calculator 'nlaunch' folder, as some of them are removed during an installation attempt.

ohhh, ok. I didn't think the folders would do anything without ndless being installed after formating the calculator.

IT WORKED! Thank you guys so much! This was the most bizarre problem i've ever had!
