S9 Hash rate is low

[capitanraj]

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.

Hello all

I have the same problem.

I'm new and my S9 does only 4.5+0.5+4.5TH on the boards.
Firmware Update helped nothing.

Anybody can help?
