Hi,
I currently am running 4 antminers s1 ... One of them is connected to a corsair RM750 psu and the hw error is 0.04 whilst I have two other miners with a corsair cx600 psu and the hw error is 1.25 .... why is there this huge difference between the values ? Could it be from the psu? Also these are running on a clock of 393.75mhz .... 200gh/s approx
It could be because you overclocked it and there isn't sufficient cooling. Try lowering the clock.
