There is no way just in some minutes to perfectly prove that a config is stable/safe.
You have to use your calculator normally for several days/weeks and check if it does crash or not.

Buf if Nover3 did set your CPU to 252MHz, then it means that it did crash at 264MHz but did pass the little test at 258MHz.

As the test is not perfectly reliable, it uses a safe margin and only sets the CPU to 252MHz which should be almost stable/safe.
Your calculator might even be able to work perfectly at 258MHz.
If it is not completely stable at 252MHz, then 246MHz will probably be ok :)


And congratulations for reaching such a high frequency I couldn't get on my units! :D

I actually got 260MHz working, but then for some Lua games it would crash on my CX CAS. But wow was it fast xD

How safe is 70MHz AHB anyway? I know AHB is dangerous, but overclocking in general is.
I'm trying to reduce the lag on GBA roms :P

Not. NAND Flash memory corruption occurs quickly with AHB at 72 MHz, less so with AHB at 69 MHz. On the CX series, the AHB should simply never be overclocked when NAND operations are involved ;)

Hi, I'm kind of new in using TI hardware, but is there some kind of unique variation between identical models of these calculators, or do the warnings in nover vary?

I've seen my friend follow a video where a guy clocks the CX CAS to: CPU 222MHz, ADB 74MHz
No problem.

But when I try to clock it I get a warning about the ADB being too high.
The best I've got was: CPU 198MHz, ADB 066MHz

Haven't tried it (in case if it's a software error)
However, if I try to clock it to 198, 066 will I get a brick worth of 154€?

74 MHz is an area of definite memory corruption, which requires reformatting the filesystem through the (built-in) maintenance menu. Just don't overclock the AHB, there's too little headroom.
198 MHz is alright.

Note that with an AHB slightly over 66MHz, the memory corruption is progressive.
So yes in the video for some seonds, 78MHz AHB will seem to work perfectly.

But the result will be the same, a full reformat some days/weeks later.

BTW, ADB = Android Debug Bridge. :trollface:
send it

I tried this and my calculator broke, didn't overclock into the "dangerous" numbers. Just tried it, restarted it and it's forever stuck on the clock... My pc doesn't recognize it anymore so no reinstall of the software... Thing's dead :banghead:
