I don't think it's a problem. Both mine do that when cold. If I let them run for a few minutes and then do a hard reboot, all the ASICs come back. They do something after the hard reboot where they run for a couple minutes, then it does a automatic softboot even though I don't touch anything and come back with all ASICs and the HW errors reset to 0. One then starts getting about .029% and one gets 0.0003%.
Very good numbers 0 errors and the asic is back.
it is pulling 442 watts about .21 watts a gh
this is with the stock enermax psu
and this one to gb fans set at 20% for true quiet note 0 hw and it also does about 442 watts with oem psu.
