I've been playing with both of the settings, to see what works best. I haven't found much luck, as The log says to disable lazy asic, but there doesn't seem to be a way to change it.

Fan is set at auto, as this thing gets noisy. I plan on switching out the fan later.

When I bought the machine used, it had come overclocked, as I think these were from a large operation where they had the room between 15 and 20° C, and it looked to be overheating. I set the minimal voltage lower so when it gets too hot it can still mine but it's at that perfect point where it will cool down while keeping a good hash rate.

I am having a problem with my spondoolies sp20 Jackson, as it tends to restart every 10 or so minutes. I get this in the log:

I marked where it says (Asic IDLE when should not be IDLE), as i believe this is the problem. I just cant figure out how to fix this.
Any help is appreciated.
