Title: Antminer S9 good hasboards but not hashing! Post by: Morescratch on May 06, 2018, 03:07:52 PM I have several S9's running with good hashboard status but the GH/S(RT) is "0.0000" for every board. When I reboot they start hashing but quickly fall back to "0.0000". The chips are running hot at 90+. Any ideas on what is going on? Could it be network?

You can try different firmware. If you brave and stupid (like me), you can try the fixed frequency firmware as a last resort. So far, I have not bricked anything doing that, and once in awhile it helps, but your mileage may vary. Basically you have a card that is failing. The trick is to see if you can find some firmware that bypasses whatever is going wrong. Good luck, and welcome to the world of shitty, but cheap, S9s. I have personally sworn off of them, after buying about 150, and only buy Avalons now when I can catch a good sale. Title: Re: Antminer S9 good hasboards but not hashing! Post by: Morescratch on May 06, 2018, 03:39:04 PM Actually, looking at the kernel log I see that the temperature is too high! Bummer. Any idea on why this particular machine might be experiencing this? I have many other machines on the same rack and they are all running at "normal" (e.g. 70-80 degrees).
Code: Fatal Error: Temperature is too high! Title: Re: Antminer S9 good hasboards but not hashing! Post by: ccgllc on May 06, 2018, 06:09:09 PM Open it up and see if you have dust, dead moths, or lose heat sinks?
Title: Re: Antminer S9 good hasboards but not hashing! Post by: fanatic26 on May 07, 2018, 07:23:28 PM It says read failed for gathering temps so I think it is basing things off of the last recorded high temperature. Something weird going on there for sure.

IF it does start hashing above the thermal limit it will shortly catch on fire. Title: Re: Antminer S9 good hasboards but not hashing!
