Nover 3 "reset detected" loop nspire CX II
« on: December 22, 2020, 11:45:07 pm »
I just discovered that it is possible to overclock my nspire cx II, and I wanted to do this so that I could have a smoother experience using the GBA emulator and playing Doom. The only issue is when I follow the instructions for nover 3 to try its auto overclock it loops the message "Reset detected - restoring"and then never does anything, and when I try to do it manually it just freezes for a few seconds and tries to set these crazy numbers, so I have to reset it to get back to the home screen. What's the deal with this, and is nover 3 so old that it's not even worth trying to use? If so, is there a newer program I can use?

Nover 3 was created ~7 years ago for the nspire. The nspire CX II is similar, but fairly different and I would be surprised if nover 3 even worked on the CX II. That said, I don't really follow the CX II series, so I could be wrong. I just know the software and hardware have changed since the original CX models.

Okay so first, Nover 3 is not compatible with the CX II (yet), so do not expect it to work at all. I only know this because I caught some nspire devs talking about it somewhere and might be misremembering but given that it's not working for you it's probably correct. It's also not too much of a priority because all nspire games until now were written to run at the CX I's 180 MHz and the CX II runs at over double that. You should definitely not need to overclock to run e.g. gpsp.

Even on newer CX I models (like my rev AB), the auto overclock doesn't work (it actually got stuck in a boot loop that required a filesystem reformat to fix). In any case what I ended up doing was to just save the highest stable overclock values and restore them manually on a reboot (these settings were 204 MHz, 204 MHz, and 68 MHz). Then just disable hibernation (regular sleep doesn't use that much battery power anyway) and you will basically never have to worry about it unless your battery runs out.

Actually, something else that is to be noted is that the default AHB frequency was waaay to high (94 MHz, with >66 MHz being considered dangerous according to Nover 3's readme). So overclocking-related things have definitely been changing before they even started working on the CX II. It is a wonder it even ran on my rev AB (in ndless's compatibility mode).
English is not my native language. If I make any mistakes, please correct me so I can learn.

NoverII (alpha) was just released by critor: https://tiplanet.org/forum/archives_voir.php?id=2671594
The main shortcoming is that the clock speed is reset every time the calc is turned off/on. According to critor's testing the highest stable clock speed was 492 MHz.
