Title: AValon 1246 83T unstable Post by: Havane on October 28, 2021, 09:30:15 AM Hello
Since few days, I have difficulties with my Avalon1246 83T : Hashrate drops, and it reboots often. Problems occur in normal or turbo mode Previously, It worked without problem. Here are log and picture. I could catch a log with SYSTEMSTATU[Work: Out Over Hot, Hash Board: 3 ] error ; but I always see 26° / 66° in the dashboard, not high https://pastebin.com/uGH0PH9w It's not an internet provider problem, because just next to it in the same room an other 1246 85T runs perfectly. Note that fans run at 6500 RPM (whereas on other 1246 85T runs at 3500. Maybe it's ok) https://i.imgur.com/me93WKo.png Here a view of minerstat where ou can see it works during hours (days) and then it has problems https://i.imgur.com/p9yVJUM.png Any idea of the problem ? Title: Re: AValon 1246 83T unstable Post by: BitMaxz on October 28, 2021, 03:56:25 PM According to your logs, one of the ASIC chips reach 110c which I guess is the maximum chip temp before the temp protection was activated.
Here are the logs that I'm talking about check the PVT_T0 begin counting on the last 27 to the left Code: PVT_T0[ 66 69 77 74 68 69 67 69 72 72 70 66 67 72 76 75 69 69 70 72 75 76 70 68 67 70 73 73 70 67 67 71 74 73 71 67 67 69 73 75 74 70 66 69 74 70 67 67 64 67 68 70 69 65 62 68 68 62 64 64 59 61 58 61 62 62 64 61 60 63 60 63 64 67 66 64 65 64 66 64 61 63 65 82 66 65 61 64 66 64 65 63 64 110 65 67 65 65 64 62 68 66 66 64 61 61 83 66 64 63 63 61 67 62 65 66 59 57 63 64] I just include voltage because I saw 350 under PVT_V0 of the first chip before the next chip reaches 110 temps. That was your 1st hashboard the 2nd hashboard doesn't show any high temp and the 3rd hashboard it has 104c. What I guess may be the first hashboard has a bad heatsink bad adhesive or solder on that chip same on the 3rd hashboard. However, would you mind try replacing the PSU I see weird under Vo it shows 0 so it might be your PSU giving a false signal?

As the avalon is still under waranty, with log problem I coul'd ask for a new one Title: Re: AValon 1246 83T unstable Post by: Havane on October 28, 2021, 09:31:12 PM Title: Re: AValon 1246 83T unstable Post by: BitMaxz on October 28, 2021, 10:42:06 PM Thanks for your help. Where do you see "weird under V0" ? As the avalon is still under waranty, with log problem I coul'd ask for a new one Check your whole logs again you can find it there not on the part that I posted above. Look for this "Vo[0]" without quotes it shouldn't be 0 as I said above it's just my theory that it could be a PSU. You can also try to flash it first with the latest version since it is still under warranty we couldn't do anything inside your miner it can only void your warranty. Since your miner is still under warranty why not contact the support and send it back there for replacement or repair?

Title: Re: AValon 1246 83T unstable Post by: Havane on October 29, 2021, 09:20:13 PM I get the new firmware "A1246-A3201-Plus-P3600W-New-Temp65_21071301" from canaan.
Same temp problem, and with it, it can't go up to 73 TH in turbo mode here are the temp from log https://i.imgur.com/65DpxUL.png Title: Re: AValon 1246 83T unstable Post by: NotFuzzyWarm on October 29, 2021, 10:41:13 PM I get the new firmware "A1246-A3201-Plus-P3600W-New-Temp65_21071301" from canaan. 1st, it's nice that Canaan is still using temp sensors in each chip :)Same temp problem, and with it, it can't go up to 73 TH in turbo mode here are the temp from log https://i.imgur.com/65DpxUL.png Seeing that table tells me that either those specific chips have faulty sensors or the chips/cores themselves have issues. Either way, assuming the miner is happy running in normal mode that's how I'd run it and not bother with repair because of the time involved. Query: In normal mode I take it those chips are still reading higher temps than the others but are not in the danger zone? That said, I'd 1st see what Canaan has to say about it. With the Avalons at least the end user can actually replace bad hash boards themselves if they are comfortable doing it. Title: Re: AValon 1246 83T unstable Post by: Havane on November 01, 2021, 04:28:22 PM After a power on off, it loops and can't mine. It doen't accept temp > 110° on a chip. ???
Same problem if y put it outsite where it's 13° C Will try canaan support by email. https://i.postimg.cc/tg9G899M/My-Picture92.jpg (https://postimg.cc/4Y209k76) I captured the log just before the crash and after a crash before crash after 202s, where we have theses max value for temp : MTmax[108 74 111] MTavg[62 59 63] https://pastebin.com/xNDqrmRG after crash 206s, where we see "out over hot", and wrong PS value : PS[0 1214 2 0 0 1272] https://pastebin.com/ZtejwG4x if someone have the previous firmware (Version 21042001_4ec6bb0_61407fa), i'm interested Title: Re: AValon 1246 83T unstable Post by: Havane on November 12, 2021, 12:23:30 AM 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. " Title: Re: AValon 1246 83T unstable Post by: NotFuzzyWarm on November 12, 2021, 12:58:12 AM Glad to hear it's working now :)

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.

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. Title: Re: AValon 1246 83T unstable Post by: BitMaxz on February 13, 2022, 11:45:45 PM ~snip~ 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 Title: Re: AValon 1246 83T unstable Post by: unicornmangle on April 21, 2022, 12:20:36 PM 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?

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. Title: Re: AValon 1246 83T unstable Post by: unicornmangle on April 21, 2022, 07:56:44 PM 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?
Title: Re: AValon 1246 83T unstable Post by: unicornmangle on April 21, 2022, 09:51:34 PM correction its still showing 131073 for middle hashboard however before flashing firmware the unit still hashed with two boards
Title: Re: AValon 1246 83T unstable Post by: BitMaxz on April 21, 2022, 10:41:13 PM 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. - https://www.zeusbtc.com/ASIC-Miner-Repair/ Title: Re: AValon 1246 83T unstable Post by: unicornmangle on April 21, 2022, 11:06:25 PM 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!

I also tried the Aging tab and prior, the machine ran at 75TH on normal mode, and 88TH on performance. Now it is showing 88TH in normal mode. Thoughts?
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.

Usually, you can check it on API logs under WORKMODE if it's 0(normal) or 1(performance).
