Yeah, unfortunately *this* is the glitch where you need to do a full reset. I would recommend staying under 70MHz AHB to avoid any possibility of corrupting your filesystem.

Okay I'll keep it under 70. Thanks

Did you use option 4 in the maintenance menu ?

I guess that Nover and the tutorials are going to be updated with big red warnings to indicate that an AHB frequency above the default of 66 MHz could yield data corruptions...

Nover has been updated.
http://tiplanet.org/forum/archives_voir.php?id=3890

The only change is that it won't let you increase the AHB at all without telling you it's dangerous (on CX).
Unlike the CPU which froze/rebooted quickly if set to a wrong frequency, it seems it's hard to find out the limit for the AHB on CX, as the file corruption is progressive and silent at the beginning.


So you should not increase the AHB above 66MHz on TI-Nspire CX, unless you'd like to help us finding out if some frequencies between 66 and 75MHz are safe.

As you see below (click to enlarge), the maximum overclock achievable with Nover really depends upon your own TI-Nspire CX.



They're all hardware revision C manufactured in 2011.

From the left to the right, the maximum is:
- CPU 222 MHz (AHB 55 MHz)
- CPU 234 MHz (AHB 58 MHz)
- CPU 240 MHz (AHB 60 MHz)
- CPU 252 MHz (AHB 63 MHz) :hyper:

If I do increase the CPU one step further, I get either a freeze or a reboot.

Note that I'm staying in safe AHB frequencies, inferior to 66 MHz.

This is awesome!! I loaded up Pokemon ruby and it runs almost full speed without overclocking with nover. Gonna try overclocking later and seeing the results then. I am gonna see about modifying my gpsp files on my psp and working that out on my cx. Great job to everyone able to make this a possibility! :)

@yeongJIN_COOL I tried that... unfortunately I wasn't as lucky. I figured out that I could free up some memory by reloading some of the missing roms and then deleting them but for some reason when I tried to reload one of the roms (Pokemon Fire Red), the calculator rebooted and a message displayed on the computer saying that there was a connection error. I'm positive that my calculator was correctly connected so I'm not sure what happened. I was able to regain 15 MB of the 30 lost so I feel a little bit better :) . But still, I could use an extra 15 MB...

As I think I was the first one to experience filesystem corruption 7 months ago, you need several passes in the maintenance menu to fully recover from it.
- remove OS
- complete reformat
- remove OS
- complete reformat...


The diagnostic software might help too, but I didn't use it.

 I bet you could get this going a lot faster by having a different frame system. For the moment the emulator refreshes the whole frame.
How ever you could have refresh every other row each time.

That would be slower than frameskip, because it would have to do extra work for every frame even though the whole thing isn't displayed. Plus, this wouldn't work well at all with double-buffering or scaling.

Something else to note is that speed is also dependent on the game you are playing. While Pokemon Ruby runs at full speed, Mario Kart is awfully slow at the same settings.

EDIT: Also watch out when playing large games. Pokemon Mystery Dungeon restarted the calc at first run, but ran it the second time. There probably wasn't enough ram allocated the first time to play a 32mb game. Speed is excellent once it gets started though.

EDIT 2: It would be nice if there was an ndless program that could clear out the ram instead of having to restart the calc. If you close out of the rom and reopen it, it restarts like the ram is full again. Slightly annoying, but will definitely be overlooked.
