pro-tip: some of the wiring on the A9 cannot handle the current when overclocked in a safe manner.

-j

Still within all factory specs so hopefully it can handle it. There are also 2 efuses that need to be careful not to trigger.

But thanks

edit.... The voltages are actually in the same range as the miner would set in one of its modes. It also appears that the miner is ignoring the 2nd and 3rd T1pllx from the config file.

Yup - the voltage stuff has been documented for many months now.. and one of the places where additional code needs to be added to support it.

My comment on current was not made out of the blue -- burnt wiring will happen if you push these.

core voltage is expected to be no more than 900mV "in range as the miner would set".

re: efuse. Don't mistake the existence of these on the die for "what is in any of the code paths". Check and see if pin16 is high or low -- probably low. And if so, that means you can't trigger them via SPI, which means you can't trigger them via "the firmware".... plus it just isn't clear that they do anything, whether they are single fire, or resettable. in other words, nothing to pay attention to nor be "careful not to trigger". ... and if it is high, then simply don't write to d08000000 via SPI.
