The device is running with its standard settings (ie. sleep mode fans at around 60%)

Current sound (Decibels) taken next to it: https://imgur.com/a/rBPaPuQ

And sound generated by it through a door and being 10 meters (32 feet) away from it is https://imgur.com/gallery/Wqme014 https://imgur.com/a/cgMXWZ7

Note to Bitmain: make them run a half the Wattage and I could actually afford to mine home  Grin

Thank you philipma1957, glad I could give something back to this amazing place.

I still cannot make the photos visible from links, will look into it.

go to imgur.com

click auto resize then make the imgur photo size   1600x1200  or  1280x1024 or 1024x768

First fail in 8 hours of testing is this one (translated by google to mean: 'No Data!'):



*my first image that works, thank you philipma1957

Causes unknown, kernel log will not help with much yet, but will email Bitmain to see what they say.

Only settings mingled with was the fan speed locked at 60% which appear to have been overridden to 100% as seen above.

So far the solution to it was to disable the fan control speed and restart the miner and wait for an amazing 10 to 15 minutes for it to start hashing again

Edit:
This has now happened again, 1 hour after the first time.

Watch your PCB temps.

According to https://support.bitmain.com/hc/en-us/articles/360005088914-Miner-normal-operating-temperature-range

T17 max temp is only 75deg C

It appears this model is very sensitive when it comes to temps (it must be to protect the cheaper/weaker chips used in the T model as compared to the 'better' ones used in the S models?! ).

I believe now that the power off (weird as it stopped hashing but the ventilators were going at 100% I believe) mode was due to protecting the hashing boards.

What I still hope to understand is why did it reoccur even after disabling the fan limit.

This has not happened again in the past 21 hours

As with all things mechanical and otherwise...everything is "trade offs". As far as ASIC capacity goes, manufacturers are pushing the limits of these new chip densities. I am far from impressed at the fortitude of the 7nm technology. They are all relatively fickle and overly sensitive. Of course I am spoiled. I doubt we will ever see units as robust as the S9's. I've had ventilation go off in my facility and every single S9 shut dwn due to very intense heat. Let them cool down for a while and fire them back up. ( with the ventilation fixed of course). They just jump back online and hash away happily like nothing ever happened. These new units...if this happens or they get too hot...it's RMA city. Dead boards, cooked PSU's etc. My S9 attrition rate on units that were 2-3 years old last year was less than 5%. Now with a fair representation across the 7nm entrants, I'm pushing 12-15% RMA within months of onboarding the gear. This is even with augmenting cooling and ventilation in the facilities.

This is how options look for S17e. All I had to do was go inspect elements and change "display:none" to "display:HERE" (I used caps so it can be visible on picture), you can use anything instead of "HERE".

When the newer bitmain miners stop mining due to heat the control board stays alive, just the hash boards are powered off.

I have the opposite problem. They stop hashing when it becomes too cold. Say -13C oustside temp, not sure what’s it inside the data center.

You do know that recommended ambient temperature is 15 to 35C?

yeah my one t17e running well in a warm room 80f
and my other t17e running poorly in a cold room 30f  this will soon be put into place in clifton the warmer room.

Most miners I have seen have 0-40C range.

The new 17 series of miner S17,T17 Do not like the cold with their firmware. If you load my aftermarket firmware it slowly warms up the chips if it is too cold out and will still run. We have a client in Siberia that runs them at -20C

t17+ in the house  64 th version

9:07 pm     3630.74kwatts on meter  65.2th
7:07 pm     3624.14kwatts on meter  65.3th
6:07 pm     3621.18kwatts on meter  65.2th
5:37 pm     3619.71kwatts on meter  65.2th
5:07 pm     3618.23kwatts on meter  64.9th
4:37 pm     3616.74kwatts on meter  65.5th
4:07 pm     3615.24kwatts on meter

so far 1500 watts in 30 minutes
doing about 65.5 th
early numbers  are  3000watts /65.5th = 45.80 watts a th

now 2990 watts in 60 minutes   2990/64.9th = 46.07 watts a th

now after 3 hours 45.43 watts a th
now after 5 hours 47.54 watts a th

need to get longer reads but if true to this a nice unit
I am very impressed at the power used  for my t17+  64 th

it just arrived today

Could you take a photo front and back of the controlboard?

maybe tomorrow.

I am a bit sick most likely the flu.  I just moved it from my garage test bed to buysolar's solar array.

I don't feel up to driving back over his place at the moment.

does very well on via btc



full size

https://i.imgur.com/MExXvvX.png

this unit is a freaking beast.

64-66th

and 2990-3010 watts

i wish i had gotten two of these and only 1 t17e

to be clear my t17+ 64th crushes my t17e 50th


basically 14 or 15 th more and 300-400 watts less.

lets say 350:less watts.

at five cents is a 150 per year in power cost.
at ten cents is a 300 per year is power cost.

it is 65th lets hope it just runs.
