Hi Guys 
i got my miners few days ago,
one of them have issue i think with hashboard,
its not going more then 9,200 HashRate
one chip the GH/S(RT) is standing between 2,400-2900 GH
HW was 19 when i checked but probably its more now .
i tried already to check with different power supply
i tried to reset it
tried to upgrade the firmware version
didn't help its still shows low hash rate from the specific chain no 7
even the tempture is low then the other chains.
