Topic: problem with my a1 (Read 182 times)

hi
check your psu and replace with another one.
maybe your psu is bad.

Not a good option if you are going to buy this unit there is no support here or support website for this unit.

I suggest you better ASIC miners that have support like Antminer.

If you want to look for a list of manufacturers then I suggest you read this thread

Hello,

I am planning to buy a Aisen A1 Pro. Are these reliable machines? I know some miners have trouble operating under high heat such as the avalonminer and some are better at higher heats such as whatsminer. How would you rate these Aisen miners?

Overall, would you recommend these miners?

FYI, I basically have access to almost free electricity.

Best,
Obi

Where did you get a replacement wire? It will melt if you are using very thin wire or cables.
I'm a bit confused do you have stocks of hashboard as a replacement?

What exactly second mode are you talking about?

A mostly short circuit is the reason why wire and cables are melting without a multitester we do not know if the hashboard is shorted or not.

If I were you hire a professional Hashboard technician to repair your hashboard you can check this https://www.zeusbtc.com/ASIC-Miner-Repair/

You can also get an idea of how to repair hashboard at the bottom of that page.

if found out that the wire wasnt good, so i replaced it. But the 4 hashbord heat the wire melt, so i found another hashboard and everything is fine. What is the second mode?

Chain 1 got some error at the first run but it works for a while. Unlike chain 3 stop working causes a low hash rate.

Would you mind trying to run them one by one or only chain 3 if it can run stable and know if the PSU is not giving enough power?

Also, try to clean up all PSU terminals and swap all cables to another hashboard then check for changes.

Is that Love core Aisen a1 miner?

Actually, there is no official support for this unit here or website but I will try to help you find a solution to your problem.

Would you mind posting the whole logs make sure it is the whole logs and put them into the insert code tag a # button you can find them when you edit your post above or if you have limited character use pastebin.com and paste the logs there and paste the URL here

For now the only thing that I could suggest is to try to flash it you can download the firmware from their old link below

Hello friends i am new at mining. One of my cards on my a1 suddently stopped hashing(seems 0mh). I reboot my machine and i only see three cards(chains). I saw the log file and i thin i detect the problem, but i cant understand what it really is.

First a problem with chain 1
chain1: power down

seems that chain 3 is dead but something wrong with chain 1? My miner its not new but second hand
