Hi, I have a A1246 87TH and trying to use this command for the static fan setting and it just sits on the "running command" progress bar. I also tried the Aging tab and prior, the machine ran at 75TH on normal mode, and 88TH. Now it is showing 88TH in normal mode. Thoughts?

Did you include the bold tag? Remove it just like this below

Code:

[{"command":"ascset","parameter":"0,fan-spd,90"}]

About 88th in normal mode how did you know if it's running at normal mode? Usually, you can check it on API logs under WORKMODE if it's 0(normal) or 1(performance).

And if you choose a normal mode on the pool configuration it doesn't mean it will run in normal mode it will still automatically run at performance mode if your temp is running at a cooler temp.

Is there a way to make this permanent?

Correct it was the bold brackets stuff that I didn't take out. Normal mode was observed from the configure screen showing normal selected and Log workmode=0, it is stable at 76TH now in normal at 59c temps fan at 65%.

Thank you for your help

Update, Got the correct Fan command line and it works. Machine now running at 75TH in Normal mode, it Ramps down from 90TH at the start or when changing the fan speed on the command. This is the behavior after clicking Aging on FSM one time.

can you send the command for autotuning of chips, my one chip is exceeding 120c mark and voltage is around 338, although miner is working good at 82th stable.

can you share the command line please,
thanks , looking forward for your reply

Try to refresh the miner's ASIC chips through the FMS tool you can download it from this link below

- https://canaan.io/wp-content/uploads/2020/03/FMS_V2.3.3_Windows.zip

And then look for the aging tab and select any hashboard with high ASIC chip temp.

If it still overheating manually set the fan speed to 100% to test if it can help to cool down those chips

Quote from: BitMaxz on January 04, 2022, 06:21:42 PM

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.

Thank you for all your time and help i really do appreciate it. I had interests in learning as much as I could about the different units antminers ive had no issues fixing but for some reason i just cant get any information that i can put to use for this avalon i really wanted to get deeper into asic repair and tweaking but teh knowledge i just so spread out and picking it apart piece by piece is so time consuming. Example my miner says its a 1066 pro but they sent me 1246 firmware and said it was the same thing.

My take is the 1066pro means I have a Avalon 10 based miner which is reiterated with the AVA100 in the api logs. The original controller with the firmware they provided me gave me the same problem I even soldered on connectors and a jumper so i could flash over usb to the MM. in the end i purchased an ebay board for $300 and it worked without issue until i applied their firmware again which i now realize is a mistake.

Again i do really appreciate your help and i would of sent this to a repair tech probably but shipping is costly i have already over invested which is my mistake but i really thought miners were meant to run for years without issues. All of the information is so coveted and im kind of the opposite in that regard i love teaching people and learning myself. I think i just arrived into the mining community 5 or 6 years too late and missed the boat. I have no monetary desire i crave instead knowledge and learning of new technologies!

You are awesome BitMaxz!

If it is still showing a problem on the middle hashboard it's a hardware issue under your control board because you already swap the cables and hashboard it means that the middle hashboard is working since you said before that you buy a replacement control board and maybe you receive a defective one.

If you don't have technical knowledge if I were you I better hire a technician that knows about ASICs repair.

Try to ask ZeusBTC from this link below and also try to check the list of repair centers under that link maybe there is some repair center near your area.

correction its still showing 131073 for middle hashboard however before flashing firmware the unit still hashed with two boards

I have swapped the bad hashboard with another cable from another hashboard and the board shows up and the board i used to swap the wire now shows as bad. Do all these hashboards need to be connected in order for this to hash? There is no signs of corrosion on the terminals the control board was brand new. Do you know anyway i can revert the firmware to an older version?

Here is the log I had flashed to this newest firmware that was sent to me from Canaan through email as it's not listed on their website on the original board that came with this miner and it ended up doing exactly what its doing now. I bough

Check the logs carefully under ECHU and HASHS one of your hash boards is not communicating properly try to check the cables or swap them to another known working one.

Or maybe the middle hash board is dead. But try to clean the middle terminal first and maybe it has full of dust and rust use thinner lacquerflo to clean the terminal with brush.

Here is the log I had flashed to this newest firmware that was sent to me from canaan through email as its not listed on their website on the original board that came with this miner and it ended up doing exactly what its doing now. I bought a replacement board and it ran by then around thanksgiving 1 hashboard went out so i ran it with just two hashboards then thought maybe updating the firmware could fix hashboard as the hashboard didnt have any physical signs that something was wrong. After flashing it just says IDLE at the top.

I'm assuming its a firmware problem FMS does not let me roll back the firmware. I have tried all of the top pools so its definitely not a pool problem Im just trying to get this working so i can sell it and recoup what i can. This miner is under warranty but the process is too much for me to do. 3 weeks of usage and a hashboard dies. I realize im a nobody but i can't afford a total loss. any help is appreciated thank you.

Also im curious if in the manuals from canaan it says web ui upgrade will always fail, if this is the case why does it even have the option in the ui?

Actually, I don't know why but if you can give us the whole API logs maybe we can see the issue there.

And what pool do you mine? Take note if you are mining on Nicehash ASICboost pool even their non ASICboost pool expect for the abnormal status of your miner you should mine on other pool. Canaan gears are mostly do not support Nicehash pool so I suggest you try other pools like ViaBTC, slushpool or kano or you can try any pool from this https://miningpoolstats.stream/bitcoin

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.

Do you know why an avalon 1166pro fails to start hashing after a firmware flash? The first time i ended up having to order a new control board and it fixed the problem and after a few weeks i flashed it with upgraded firmware that was emailed to me from canaan and now it just boots and says IDLE in the webui it connects to the pool just will not start hashing.

Canaan has been horrible with customer service i dont understand how you can sell a machine at such a high price and just brush off anyone who asks questions. at the very least they could give the tools required for people to diagnose their own machines. canaan told me if i buy a lot of machines i get support and warranty. im not rich and this is truly a hobby for me and i have bled about 15k so far on mining equipment in the last 6 months.

My avalon experience lost controlboard after 3 days(had to order from ebay for $300 canaan wouldn't sell me one), lost a hashboard after 3 weeks, lost whole machine now after 8 weeks. I wrote canaan it was under warranty when they ran the serial number but there was so many steps to get it returned and they wanted me to remove the hashboard and heatsink which i started doing but they put thermal paste all over every part of that board even the slots on the case the board slides into. So many steps as in (let us remote to your machine, disassemble whole hashboard, waybill, give us your company full information(im an individual), ship, insurance, wait time etc)

I even found a broken drillbit that was used to drill the holes in the avalons enclosure stuck in the fins of one of the hashboards. I know it was for this purpose because of the size of the drillbit and it still has 4 or 5 rings of alumnium attached to it.

can you send the command for autotuning of chips, my one chip is exceeding 120c mark and voltage is around 338, although miner is working good at 82th stable.

can you share the command line please,
thanks , looking forward for your reply

Try to refresh the miner's ASIC chips through the FMS tool you can download it from this link below

And then look for the aging tab and select any hashboard with high ASIC chip temp.

If it still overheating manually set the fan speed to 100% to test if it can help to cool down those chips

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.

Quick news. After contacting canaan by email, they gave me a firmware. And with a command to auto-tune the frequency and voltage , it works fine at initial hashrate, with still few high temperature, but ignored.

For them, "The temperature is faulty caused by the IC temperature sensor" ,but I "could ignore the issue ,because the actual temperature is almost same with nearby IC temp. "

can you send the command for autotuning of chips, my one chip is exceeding 120c mark and voltage is around 338, although miner is working good at 82th stable.

can you share the command line please,
thanks , looking forward for your reply

It can also be bad thermal contact between that particular chip and the heatsink
