23/11 Blissz is working great:
Frequency = default 487
Voltage = 9
Hashrate = 17100 MH/z
Fan = Performance auton (4020rpm)
PCB temp = 55-57c
Chip temp = 71-71c
HW = 0

I'm wondering what makes temp rise above stock (65c) while under volting and stock clock? Hashrate is about the same with stock firmware.

The default auto fan speed is a little lower. Set it to performance and your temps will lower. Furthermore I think you can undervolt a bit more at that frequency.

Now asic voltage is 3-4, frequency default, fans 3810rpm, chip temp 69-70c and 17100MH/s (0 HW).

What the real values in asic voltage scale lowest-highest?

I think you're on a sweet spot then. The fans run slower compared to bitmains default now and power consumption will be ~150 watt lower compared to stock.
I don;t know about ASIC chip voltage, but for the total voltage per chain it's close to this. (I can't tell exactly as my unit hardware modded as well)

lowest = ~7.5v,
default bitmain (setting 10 - 13): ~8.2v,
highest setting: ~8.8v

Thanks for this info! Now after short reboot test I think your firmware has fixed my boot problem. Before with bitmain firmware it was in "test loop" 8 out of 9 boots.

I need to check watt usage shortly. I bet it's lower than before!
