For those having a dead hashboard we need to regroup and  send a strong message to bitmain to have a quick support.
For those interested by this approach. Please send me a PM and I will add you to my message.
At the end of the day we invest a lot of €€$$ and we are loosing money everyday and we all know it will be difficult to catch

Eh... won't they just send you to their warranty? Dead boards are really common with most anminers, S9s lately have been terrible.

S9 and L3 is a long term investment you have you ROI between 4 to 9 months because it is mining different crypto. In our case it is a short term investment. Most of us have lost 800$ because of dead hashboard next week we will have maybe 8$ per day who knows bottom line we are losing money instead of few days to recover it it will take months and ROI is even longer

My antminer A3 arrived one hashboard dead .
1st time I plugged in,One blade is dead.
PLEASE see the picture.
http://fantom.tokyo/A3config.PNG
then
http://fantom.tokyo/A3ASICDEAD.PNG
and
http://fantom.tokyo/A31DEAD.PNG

so I switched 18pin cable connection 1and2 and still board1 is dead(this time board1 is chain2)
http://fantom.tokyo/A3changeconnect.PNG

So please give me advise:-(

Same happened to me with two different A3s. Did you solve the problem?

That's just a dead board plain and simple. Aside from getting warranty work done on it there's not a lot you can do. Could be power circuity, and if your good with soldering iron you might be able to fix it. But i would not advise doing it while under warranty. I'd just get it replaced. Unfortunately profitability is going to be much less by the time you'd get it back. Personally i'd ride it out on two boards till the gold rush is over, then send it in.

Unplug and replug the white control cables. CHeck them to see that the wire is actually done properly, IE the crimp to the metal pin on the inside of the plug,  you can check with a multimeter.  I had an issue with an Improperly seated connector on an S9.  replugging fixed that same problem.  If the board was dead, or the asics you would at least have PCB temps on the screen for it.  This means no data/control from the board.

It doesn't work have the feeling it is a software issue like the D3. The have an upgrade for it.......I hope they release a software.
Currently they are supposed to be back to their office but no news so fare. Will keep you posted if I have any update

On Siamining stats page, pool and network hash rates are starting to level out?  just wonder how long that will be. I was AMAZED at how many less coins per hour the A3 was doing in the last day,  went from 330 per hour yesterday to now at 164 per hour  That was over a 18 hour period.
YIKES!  as long as it makes more than an S9 I'll be happy

Forum member Mr. Bliss help me out with firmware and I flashed it.
But Ohhh one hashboard is still dead 1st shows 3 ASIC alive but in few minute dead.
So My friend our BLADE came faulty.

All we have to do is now asking BITMAIN for treatment.

People with fine A3 congratulation for nice harvest .
Who are not let's do our best .
Peace out.

That looks a lot like a Power supply problem,

Try to unplug PCIE cables from boards 1/2 and chain 1/2 --> test board 3 (see if it works)

Then,
Try to unplug PCIE cables from boards 2/3 and chain 2/3 --> test board 1 (see if it works)
Then,
Try to unplug PCIE cables from boards 1/3 and chain 1/3 --> test board 2 (see if it works)


If they all three work then chances are it's a power supply issue.

Another thing, try to move the location to a different wall outlet and test it there that sometimes works for me.

Hi boneyg001,thanks for kind advice!
I did tried one blade test actually.
But testing order was different.
From config panel it says chain 1 is malfunctioning.
So I did chain 1 first.
And it didn’t work.
Is that important the order you suggested?
Then I had better try it?

The power voltage is 1 phase 200V.
I tried 3psus 2x AWP++ and third party 1800w.
All worked fine with D3.(which I got rid of for this A3.)
So I think PSU is okay.

But one thing I wonder is when I reboot it.
When starting noises went down it shows miner status
And many times the number of ASIC is slightly different.
Sometimes chain 1 doesn’t show at all .
Sometimes it shows 3asic alive then dead.
Sometimes it shows 6asics alive then dead.
Sometimes 4........
Strange, maybe something like coil on the board is attached loose.

Anyway at this moment disassemble myA3 now is risky about warranty issues.
I will wait for Bitmain reaction.
Hope it will be quick.

I am having this issue since 3 days. Tried different PSUs, changed the data cables, plugged one hashboard after the other and still not working....same story.

Do you think someone else archive of backup can help?

Just received the miner. It is freaking loud at my apartment. I am pretty sure someone is going to complain. I tried setting the fan speed to 70% but chip temperature is going beyond 90 C. What is the ideal fan speed and temperature guys? PCB is around 70 and chip around 100.. Is that too much?

PCB can never go to 80 or it will break...

Try to keep it at 60-70 for best results.

I recommend opening your window and pointing the outtake fan towards it. Also, You can only lower the fan if you are going to lower the frequency as well otherwise it will overheat.

I recommend getting earplugs to sleep because it will be hard but would be best for right now. Either that or call a friend and ask them to run it in a spare room for the next 1 week while you buy fan shrouds, cooler, and insulated flexible duct to make a box to silent it a little.

Let this be a PSA to everyone check your temps. If the chips are over 80C you need to ramp up the fans. With 75F/24C ambient temps, mine would hit 75C with 100% fans! I moved the miner into my garage with 32F/0C ambient temps and the chips are still running 65C... If you are hitting 80C or higher you are risking a dead board during the time this thing is most (or possibly at all) profitable.

PCB temps or chip ?

my default  PCB temps are like 61-62 but my chip temps are 75-84

if i raise frequency to 625 pcb stays at 68 but chips are at 90s 80s

Using ACs to cool your miners is extremely inefficient. Your profits will be reduced considerably. 65~75 temps are fine.

Window is open and people walking outside can hear it very well. It is like a vacuum cleaner running lol

Right now, the fans are at 5800 RPM (auto mode), PCB is 65-70, chip temp is 90-92. Getting 830 GHS

I tried setting fan speed to 70%. That significantly reduced the noise but chip temp were at 100 within few mins. I switched back the fan speed to auto. If I let it say at 70%, chip temp would hit 110 I guess. lol.

Now, what is the max chip temp that is "ok" for device to at least last 6-7 month?

If I want to lower the noise, I guess I have to underclock. Is "frequency" the settings to underclock? Can you tell me what range I should try changing and play with so I can lower the noise (and also hopefully keep the temperature ideal)?

Sorry about too many questions. This is my first ASIC. Have been running GPU rigs always...

You could always just stick an AC in front of it. Thats what i did. Two x10s (50% fan speed) and one Bitman A3 (30% fan speed) . They only thing i hear is the AC and thats just a hum. When you change the frequency low or high you need to load firmware that will support it or its possible it will reject all your blocks. P.S. Im gonna work on making it look nicer when the second A3 gets here lol Good luck!!

Some local guy is trying to sell one for $8500. Will these be hard to get? I know they are sold out now.

im also selling same price. i would think so because chinese new year is approaching soon, so dont think bitmain will be releasing another batch til march.. lets hope so.

Sorry about too many questions. This is my first ASIC. Have been running GPU rigs always...

I underclocked mine to 550 and they're still running at 75C with 30F air on the input side.

I do not have a portable AC to point to the miner. Silly question - when you say input side, it is the side that has the ethernet port, right? Also, which side should face the window? Smiley The side that blows air out like crazy right? And the ethernet port side should face inside the room? Correct?

I lowered the freq to 550, PCB is at 65-70, chip temp at 85-90. Outside temperate is 30 F and the big window in the room is open but its still running so freaking hot.

Will this fan do any help for my situation? I do have that lol - https://www.staples.com/product_2143666


Have your window all the way open as much as possible. I'd aim the Hot air towards (backside without ethernet) towards the outside window so the room it self-stays cool. With the window, wide open, the cooler outside air should come in and reduce the temperature. Keep the fan setting on full and possibly consider shutting the miner off for 10 minutes and letting it chill either outside or with a cool fan blowing on it.

If you have that fan go ahead and you can point it towards the intake (front) side to try and cool it down a little. Otherwise don't bother buying that.

That's just a dead board plain and simple. Aside from getting warranty work done on it there's not a lot you can do. Could be power circuity, and if your good with soldering iron you might be able to fix it. But i would not advise doing it while under warranty. I'd just get it replaced. Unfortunately profitability is going to be much less by the time you'd get it back. Personally i'd ride it out on two boards till the gold rush is over, then send it in.

Mr. SIN3R6Y thank you for your suggestion. And that's what I am thinking of
I lost HIGH TIMES of 1/3 with dead brade and more time with tons of rebooting.
nwo I'm in siamining 'cause Luxor caused HW errors and couldn't mine.
So I stick with siamining for rest of harvest.
And later repair.

repair? what for? later it's gonna be another brick in bitmain's wall

Wow, Over 2200 new A3's went online in the past 24 hours !
Network went up from 500TH's 4 days ago to 2700THs..

difficulty is at 2.3T

have you reset it?

My case it helped.
