I'm curious of the same thing - I have undervalued (0xfe) and overclocked (612) - curious of the effects and energy usage. Sadly I don't have a wattmeter other than what the power company is telling me; which doesn't help when it's summer time and A/C usage is already higher than usual. I am curious however if anyone else has undervolted + overclocked and what their experience was - hashrate/power consumption/stability - etc. My unit has ran significantly cooler on the undervolt setting. It's outside in window well because of the noise. Outside temps reach ~100 F some days. PCB usually peaks at 76 C.

I love what this can do - Any interest in creating one for the A3 miner?

Hey team. Thanks for the sweet script FNT. A quick question about this - If I unplug power, and plug it back in, do the voltage settings remained unchanged? If I reboot the device from the Antminer config page, does it retain the custom voltage settings in that case also? Sorry, I did not see this question asked/answered already; I'll blame poor eyesight.

Thanks again for the help. Any suggestions on a good place to better understand voltage settings in hex for the ant miners? Curious what you all picked to save the most energy while maintaining an average hashrate of 815GH/s or above.
