Topic: Anyone else having issues with their Antminer A3? (Read 2291 times)

hello
i have bought a A3 recently.
the hash rate in siamining is around 40GH/s
is it normal?what should i do?
(antminer a3 815GH/s?)
please help
im new

who has the device still in use?

just another suggestion guys...under your advanced settings in miner config....set your freq to 600...the system seems to default to that....I had the issue also and I manually set the freq and fan speed to 75%.

Save and reboot.

While debugging the device according Bitmain instructions I came to know, that two hash boards are faulty. I sent them back to Hongkong for repair... It is unfortunate situation, the post is really costly and this device seems to be really time dependent, the profitability falls rapidly down...

I have the same problem with the brand new A3 miner. The fans power on, but there is no green nor red light, there is no IP, reset button doesn't work...I cannot do anything with it...is it a control panel malfunction or what? fan is going on and off every minute. logs show that FAN1 too slow, FAN2 too slow. Hardware version shows as "Socket connect failed: Connection refused". Tried reboot and reset. Nothing worked. can anyone help with this?

Hi,

I just received my first Anminer - A3 version and having similar problems, only 1 hash board is functional. Using Bitmain PSU@220V. I will try advice that JacobHarding suggested, do you have any other advices that has worked for you? I will also check to reconnect the PCIe and localize the not working hashing boards. My hash board #2 is visible, but having xxxxx instead of 0000... and the third hash board is not detected at all...

Thanks for any advice

I have a problem with the brand new A3 miner. The fans power on, but there is no green nor red light, there is no IP, reset button doesn't work...I cannot do anything with it...is it a control panel malfunction or what? I tried everything including flashing via SD card and nothing helped. Help anyone who can

My device is being repaired

Ok kids,

You all look like awesome boffs.

But looking at the kernel log of john smith back there he look like he is having the same issue i was.

Pop out your control board. Yep disconnect all your cables.

Flip the cboard over and look at all the solder connections.

I found horrible white powder. Yep the low silver content causes the connections to 'decay'.

I fixed it by getting a new toothnrush and give the ol girl a good scrub to clean any of the offensive unwanted powder out.

Whack her back in and see how she winds up.

Ask me my sia coin addy for a generous doni if it works.

Power supply makes barely any noise if it's a APW3++.  The fans on the antminer A3 itself are very loud (6000 RPM) at about 85DB.   

Plenty of methods to make them quieter and cooler, just look it up on youtube.  Better yet, put them somewhere they won't bug you and let them go.

Just buy another power supply.   The power supply is the noisiest part. 

David71j could you confirm you have a failed board by switching it to another set of connectors and seeing if it in fact is a failed board and reads CHAIN 0 has 0 ASIC again in kernel log, this should confirm if you need to send it back to BITMAIN

Yea I doubt this thing will survive any form of air constriction or deprivation too tight with heat sinks... OP sorry bud seems everyone has hijacked your post with not much help

Network issue likely, check static/dhcp settings

HW errors are not a big deal there is a formula I posted in earlier pages of this topic variation in hash is not unusual

Ok the A3 does not like high temps above 90 Celcius at all. this will probably cause issues with HW faults and then become dead XXXXXX. For some reason its fans appear not to push enough air flow when I have it set up with my other set of four antminers 4 inch vent tubes going into the homes ventilation system per a 48 inch vent box that is sealed and connected using a 2 inch by 12 inch vent riser. I can feel a back force of air when tube vent not hooked up to back of A3, so I instead ran a separate straight outside through my window by 4 inch tubing and a 4 inch vent that is screwed to a board sitting in the window. now my temps are at about 80 on all board chips of A3. I figured it out by testing on desk for 1 hour with temps only reaching 75 celcius and never had an issue but a few HW. I originally had a failure after I left It running for the first time went to sleep and it was all XXXXX on boards, after looking at the statistics page per my miner address I found out it quit at about 2 hrs and I'm sure the temps raised up to 90 and above, I highly doubt that it ever got to 100 celcius because when I tested this morning and when I got off work it would fail at about 95 across all 3 boards of the miner, so don't believe when elsewhere I seen someone post Bitmain told them acceptable temps up to 115 celcius. good luck. By the way I did play with the frequency by lowering it but it never helped me I still got many faults every time at the 3 minutes running mark of the A3 when rebooted.

tssssss

how can i reset the control board  its locked up

Hello guys.i have situation about quantity of errors of A3.All chips are 000 but the quantity of errors is about 110K after 1d5h restart with 850-880Gh and frq 631m,it's after when i made it down for one step frq,before it was even more errors about 450k for 9hours work.
and hashes so jumping up and down from 850-890gh is it normal situation for this machine?temp on chip 61-68
who can recommend smth?

i will send 75$ coin bounty
