Silicon lottery aside for the moment, at default frequency, what's the lowest voltage people have been able to maintain? At 710.4mV right now, 598MHz, seems to be stable, HW errors are reasonable

I had 598 at 740.1 mv errors were 0.6%
I am now testing

598 at 722.85 mv errors are 0.9%

Cool good to have a comparison, at 710.4mV, I'm running 1.3% errors. At stock voltages and frequency (eco mode not custom) i'm around 0.9% error to 1.1% error.

If I go to 697.95 volts
and 559Mhz freq

I get 93.92 hash with 1% errors

and I can set fan to 10% temps are 54.88/50.22 in a very warm room.
I will run this for a day

I suspect if you don't mind losing a little hash rate

you can set lower

lowest volts is .644
maybe with 500mhz freq
5% fan
