Title: Diminishing Hash Rate Over Time Post by: shitmexanon on December 15, 2021, 03:54:38 PM Hello all
Have a Canaan AvalonMiner 1166 Pro that has been losing about ~0.1TH/s per day. The boards are not overheating (62° C, 65° C, 67° C,), and the fan speeds remain under 60% (~4500 RPM). These temperature/fan-speed conditions have remained fairly constant for over a month but now the hash rate seems to be slowly but consistently decreasing. I am not clear as to what could be causing this behavior. The ASIC was advertised to get 81 TH/s, but really never performed above 79 TH/s when I first got it. For months it performed in the 76-78 range and now is around 73.6 TH/s and decreasing with each passing day. Any thoughts? Actions I can take? Should the boards vary that much in temperature? Thank you Title: Re: Diminishing Hash Rate Over Time Post by: BitMaxz on December 15, 2021, 04:30:53 PM Have you tried to reboot the miner? Let see if it could fix the issue.
If not then post the API logs here and don't forget to put them on the "insert tag" with a # icon or use pastebin.com and paste the URL here. The hashboard temp sensor is different so maybe we can see the real temp of the chip under PVT_T0, T1, T2, and maybe one of the chips is overheating that cause this issue?

In fact as I am typing this up my miner just restarted its self. It seems to do this ~1x per week, unclear why. This time was <4 days. These are the logs minutes before it just restarted.

Title: Re: Diminishing Hash Rate Over Time Post by: HagssFIN on December 15, 2021, 08:55:02 PM I could not find meaning for number 4.
Can you try tightening the connection between MM board and the hash boards? Just in case if it is loose after transport or something. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on December 15, 2021, 09:05:42 PM I'm not sure what MMboard stands for or even which part of the miner that is. Internet searching hasn't been helpful for this term unfortuantely.
Title: Re: Diminishing Hash Rate Over Time Post by: HagssFIN on December 15, 2021, 09:15:04 PM The help is more close than you think, have a look at my Avalon troubleshooting guide https://bitcointalk.org/index.php?topic=3224256
It's the control board for your hashboards. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on December 15, 2021, 09:32:54 PM perfect thank you. Do you suggest I just un-plug and replug the ribbon cable, tighten any screws on the MM board, and ensure the hashboards are slotted in well again? Anything else?
Title: Re: Diminishing Hash Rate Over Time Post by: HagssFIN on December 15, 2021, 09:34:44 PM Yes, that's pretty much all there is to it.
Title: Re: Diminishing Hash Rate Over Time Post by: mikeywith on December 16, 2021, 09:22:18 PM The ASIC was advertised to get 81 TH/s, but really never performed above 79 TH/s when I first got it. For months it performed in the 76-78 range and now is around 73.6 TH/s and decreasing with each passing day. I think most asic miners are rated at +-5% so 3-4TH missing on an 81TH miner is pretty normal, what's not normal is the diminishing hash rate, this is a very strange problem, I believe your miner is auto-tuning itself and for some reason, it doesn't see the miner at a stable state with the current hashrate so it tunes the frequency to a lower figure just to keep the miner stable. I don't own a similar gear but speaking from experience with other miners, the tuning part can go wrong at times, so try to flash a different firmware just to make sure the firmware isn't falling at tunning the hash boards. Title: Re: Diminishing Hash Rate Over Time Post by: BitMaxz on December 16, 2021, 11:36:25 PM Hello Everyone I had the same issue with 1166 pro-81TH but from yesterday, my miner keeps rebooting itself. Can anyone help me to diagnose the problem? Yes, both of you have the same ECMM[4] which is abnormal but we do not sure what is ECMM[4] you can't find that number on their description logs. However, this is what I noticed and found this under your logs WORKMODE[0] which is it's running at normal mode it means the hashrate drop to normal hashrate maybe around 50-60TH/s What I would like to suggest is to force the miner to the high-performance mode you can find it under configuration then work mode or use the FMS app to force it to high performance. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 04, 2022, 10:17:39 PM Been a few weeks since I last updated here. I have not yet taken the machine apart to ensure all wire connections are snug and screws tightened. Since then I have notice the miner still restarting itself about once every 3 days, even in cold easter (<50 degrees F). Today for the first time it turned off and simple did not restart itself. I had to manually unplug and replug it. Looking at the logs the ECMM[4] is still showing and this error code is not documented in their manual. Additionally I noticed the HW code frequesntly changing with values ranging from 97 to 119 for the few minutes I monitored the logs. The number only increased over time. The manual simple says HW means Hardware Error but provides no guidance on the codes.
If anyone has any idea what is going on here please do advise. Thank you. Title: Re: Diminishing Hash Rate Over Time Post by: BitMaxz on January 04, 2022, 11:21:42 PM If the logs you have are still the same as your previous logs above then I suspected that some chip temp is fluctuating above 85c. Since you have a large number of HW or hardware errors some chips are overheating and the hashboard will automatically disconnect if it happens then you will get ECMM[4] because it's disconnected automatically for protection and it will attempt to restart.
Another thing that I noticed from your previous logs is that the fan speed is not stable. What I would like to suggest is to try to set the fan speed to at least 80% or 90% and let see if it will run stable for long. Just try even you have low room temp. To set the fan speed you must have the FMS tool and then go to diagnostic and put this command below Code: [b][{"command":"ascset","parameter":"0,fan-spd,90"}] [/b] Fan-spd,90 it's a fan speed with 90% you can replace it with 80% or 100% to try if it fixes the issue. Another solution that I would like you to try is to use the aging you can find it on the FMS tool along with the Diagnose it can calibrate all ASIC chips. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 04, 2022, 11:52:00 PM Interesting. I will have to get a Windows machine in order to get FMS running. Likely a weekend project. The ran speed is and has been always fluctuating up and down about every 30 seconds or so. The rooms ambient air is in the 80 degree Fahrenheit range but the machine is drawing outside cool air under 50 degrees Fahrenheit. I would like to get FMS going and set a fixed fan speed.
Title: Re: Diminishing Hash Rate Over Time Post by: NotFuzzyWarm on January 05, 2022, 12:33:24 AM You would be better off having the down right cold outside air mix with the room air and having the miners draw in the now cooler room air. Thing is miners do not like to run at chip temps much below 60C (140F). Reason is that being a power device, high temps are a natural part of the territory and semiconductors behave differently as temp rises. That is why miners have a pre-heat cycle before really starting to ramp up to full speed.
Ja the miner will try to control the temp by adjusting fan speed but that relies on Canaan properly tuning the temp/speed control loop... Point is the miners may just be too cold.

Another solution that I would like you to try is to use the aging you can find it on the FMS tool along with the Diagnose it can calibrate all ASIC chips. I got FMS installed. You suggested using aging which I do not see in the tool (I have tried V2.3.3 and V2.1.0). Do you know where I can find a list of commands or manual to know how to make the commands for the diagnose console? Doesnt seem to be in their manual. Thank you.

Other versions of FMS don't have an aging button there are two FMS v2.3.3 the one is the app version that doesn't have an aging button. You can find that button in the FMS v2.3.3(batch version) you can download it on Canaan technical support. Or check this link below to download the batch version. - https://canaan.io/wp-content/uploads/2020/03/FMS_V2.3.3_Windows.zip Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 10, 2022, 04:03:24 AM Ok I installed and ran the aging tool. Now may hashrate is diminishing rapidly. Within 10 mins of reboot it got up to 76 TH/s then over the next 20 mins declined down to 68 TH/s. Fan running at a constant 51% with temps steady between 63 and 68 degrees. Any thoughts on cause or action to take?
Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 10, 2022, 05:35:56 AM Linked image of a graph showing hash over time and how it dropped down.
https://i.imgur.com/E4wQKbS.png I see the ADJ field in the logs has a value of 0 which the manual indicates means aging is in progress. Perhaps this hash behavior is a result of the process? Any idea how long aging takes to complete? update: ADJ[2] now shows indicating aging finished. Do I need to do a restart or do I let her keep running? Hashrate now up to 71 TH/s (still low) Title: Re: Diminishing Hash Rate Over Time Post by: BitMaxz on January 11, 2022, 12:00:10 AM You didn't follow what I suggested in my previous post as I said try to run the miner at higher fan speed. Because I notice TMAX reach higher temp.
Also, keep updating the API logs here so that we can analyze your issue well. And normally you can't force this unit to run at high-performance mode but you can prefer to switch work mode to performance mode. You can find it under configuration on Web UI. This unit is not running stable at high-performance mode it automatically switches if they detect high ASIC temp. Look at your previous logs TMAX it shouldn't reach above 85c as a recommended chip temp. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 12, 2022, 04:11:15 AM After the aging process completed and I wait a few more hours, the hashrate is up to 77TH/s. It seems that the aging did do some good work. As for your suggestion of running the fan speed in the 80-90% range to see if it will run stable for long, if I notice the chip temps dropping below 60 should I end the experiment? I fear that this will keep the chips on average too cool. Seeking your opinion before executing the experiment. I don't believe the ASIC has toggled off of the performance mode before but I also haven't checked to make sure, my only evidence is that in the nomral mode it will hash in the 50TH/s range and in high performance above 70TH/s. At no point did the ASIC ever hash consistently in the 50s, except for the few hours during the aging process. Here are some current logs:

Watch this at the end of your logs WORKMODE[1] it means it's running at high-performance mode. Well, you said it's running fine now after the aging process, so keep monitoring the miner for 24hrs and let's hope it will run stable at that speed. Title: Re: Diminishing Hash Rate Over Time Post by: shitmexanon on January 13, 2022, 01:14:50 AM great thank you for your help. High performance mode is enabled. Something must still be happening that occasionally the TMAX will get high every few days and cause the machine to restart. Will see if that still happens now that I have done the aging.
