Hi,

is it possible to underlock the antminer s1?

I would like to reduce the heat (and therefore the noise!).

Let's say I would like to underclock it from the standard 180 Gh/s to ~150 Gh/s. How much noise would I have to expect? And does it also have a significant reduction of power consumption?

Thanks

Yes you can, and there are settings already in the /etc/config/asic-freq file. Just comment out (add # in front of) the 3 lines that are currently loading for 350M, and remove the # from the lines for 300M, or 250M to underclock. Save the file, and reboot the Antminer.

It will lower the temperature, fan speed, watts, etc. For me it's around 25watts per 25M I lower it. Setting it to 250M makes my fan run at <2000RPM which is much quieter.

I tried that already with no luck. Sad
