i had the strangest reply from bitmain support today. one of my new s9's has been running 1.5th/s slower than it should be since the day i got it which is out of spec by more than double the numbers posted by bitmain. anyway i was talking to a very nice person names "barbara" which im sure is a fake name like when you call comcast support and get someone in india or south america....but anyway she was working with me then randomly this person with the username "overseas" takes over my ticket and asks me to do everything that i already did and when i replied back telling him no i already did all of this he came back and said basically my miners are cooled too well. he said i need to raise the temps in the rooms i run my miners in because my miners are running too cold. the funny thing is all of my s9's are in one room while my s7's and titans are in another room in the building next to it. each room has its own dedicated ac unit pumpin nice cool 65/70 degree air into the room. the room with all s9's runs perfectly (same with the other room of course but this is about the s9 miner not the other miners) except for that 1 s9 that runs out of spec.
i usually back bitmain to a certain point unless im wronged because i cant go by anyone elses experiences except my own but who would have thought i would get a reply back telling me to run all of my miner hotter and harder in order to fix this one miner running outta spec? all of the other s9's run perfectly at the temps selected in the room so what makes this particular miner less willing to run at spec? it doesnt get anymore extra cooling that the other s9's dont already get. its plugged up to the same 230v apc 5000w pdu as 2 other s9's are but somehow these speeds are my fault and not bitmains fault....lol not likely. just thought i would throw this info out there because i found it amusing.

if your miner using there new auto freq firmware
i lost 3 TH/s from mine and after a week with them on a ticket i told barbara to move my ticket to some one more experiences and he did
after that (Customer Service-Overseas) take my ticket and they asked my kernel log more than once, every time this issue happen
after all they told me that (There is a bug in our latest firmware. We have fixed it.)
my miner now working for 1d18h31m41s without losing hash rate but i will upgrade it now for there latest
