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€?
