Ya, 120 MHz is bootable, but when pressed, usually falis. You might be able to get 117 Mhz stable on a BL3, but probably at 3x39 MHz, and with a peltier.

In heinsight, we probably should have made 120 Mhz the upper limit on the clock gen module, rather than 110 MHz. But alas, I doubt few people are going to try running a BL3 at 2x57 or 2x60 MHz.

I've had a few case buttons go bad - power, reset, or turbo bottons. It resuts in sporatic behaviour, resets, etc.

Yeah.. I'm not sure why people are adverse to using level shifting for a proper design. But then again I'm sure the people/AI doing the design don't have any engineering background so they don't know it is important for stability or to prevent IC damage.
