Hi community,
I turn to you as I need some help if possible.
I have an Antimner a3 and one of the boards is not working. Tried changing power, moving back and forth but always the one in the middle (board 2) do not work. Tried booting the Antimner only with it connected also did not work.
Sometimes the board will not show at all, sometimes (when I lower to 550 )will show with few Asics but all XXXX XXXXXXXX.
Tried factory reset few times, tried power off/on, restart .... none of it changed anything.

Any ideas if there is any chance I can fix this other then sending back to Bitmain?

p.s. if anyone manages to help me to solve this will permanently mine for you for a day.

I just kept it at 525 for a while and after 20 or so resets (which it does by itself!) it started hashing again. Then kept changing frequencies until it hashed at 600 again. Good now for a day.

Same middle hash board with the lowest number of HW errors and running coolest of 3.

Tried that but didn't work, tried even lowering down to 400ish but still same situation. Actually for these settings the board is disappearing if I move it back to 550 it shows up again and it shows 47 ASICs existing but is not hashing at all.

Had same issue. Tried everything! Different PSU, swiched cables, I/O board, factory reset, reflash, frequency changes, nothing helps. There is a lot of us that received A3 machines with one or even two dead or semi-dead hash boards. There is nothing you can do. First determine which board exactly is dead, open up the back of the miner and take it out (https://www.youtube.com/watch?v=ycDbpWVHQEs). Then open a support and repair ticket with Bitmain and hope for the best. 

PM me if you need more help with the hashing boards. I can also send you the original FW for reflashing the miner. There were reports that some guys managed to solve the issues with that. I had no luck...

Hi has anyone noticed any transactions/payouts from Siamining pool missing in the Siacoin wallet?

I've had one payout 3 days ago not show up in my Sia wallet and again another one few hours ago not showing up in my Sia wallet. See circled transactions in image below.

All-Time Paid Out: 34,695.83 SC from Siamining, but confirmed balance in wallet is: 32098.87 SC, so i'm missing 2596.96 SC

If anyone's experienced this please let me know what you've done to recover the missing payout.

BTW, I'm using Sia-UI version 1.3.1 wallet.

Difficulty starting to rise?  Or increasing hash power?  See that I am getting fewer coins since yesterday....


No missing payments on my side....

Very common problem with the 1.3.1 UI Wallet, I've talked with other pool ops and their users have the same issues. See here for how to fix it https://siawiki.tech/wallet/lost_transactions_troubleshooter

You can always verify the pool has issued the payout by checking the TXID and looking at in the explorer.

Yes, I use the same wallet am also missing a payment from SIAmining from a few days ago. The payment is on the blockchain, so it is a wallet issue.  I located these same recovery instructions but have not tried it yet because it seemed sort of cumbersome/risky.  At some point in the future, I will probably empty the wallet before attempting recovering the payment, since it looks like you have to completely delete and 're-seed' your wallet.

Thanks xurious for the quick reply. I'll give lost_transactions_troubleshooter a try,
but like Tekno2020 (thanks for your tip) mentions at a later date after I've transferred existing Siacoins out of the wallet.

Hi Man, I had the same problem and after a few reboots and refirmwares I got all fine... but still not hashing.... so i sent it back to china. They "repaired"it pretty quick I have to say. Got it back today and guess what... it works!! but only if I do not change any setting. so even changing one pool result in losing connection and not being able to mine. 

so after trying several things it seems a pure luck combination of resets and got it back to work. it is just insanely HOT and have to cool it with -4 degrees outside ait and even then its still 83 degrees!! CRAZY!! its all but quality if you ask me. anyway, answer to your question: its a bad product and have to be lucky to get it to work and keep it a bit cool. maybe BLISZZ will come and make some nice piece of custom software for it.

I've order one from this batch. Fully expecting the difficulty to go up so much in the next couple months while I waiting for it that it will just be a paperweight by the time I receive it haha

[Dlikrot]

If the price was 500 usd I would grab a couple.... Now I won’t bother...

[johnny_blaze]

there's no microSD slot on A3 in comparison with S9...
does that mean that i will be unable to unbrick my A3 if sh1t happens?

[Ulewap]

what is the tolerable HW for each board running 24 hours ?
I got my HW on each board:
1. 11,000
2.  1,121
3.  3,444
For board #1, is it still okay for running 24 hrs already?

as long no XXXX appears is good. I think its inevitable with the A3. I have them too

[Ferr]

Is anybody could order on EN site with shipping to Hong Kong? For now site said that "unable to ship to mainland China"

[Sanctum09]

My experience with the A3: Total of 4 purchased direct from Bitmain. All are overclocked by +668, running in a 2-car garage with the door closed and zero ventilation, along with 4 other ASICs and 1080 Ti x16 GPUs. Mining non-stop since January 27th with zero reboots, averaging > 900 GH/s per A3. Have no choice but to give it 5/5 stars so far.

Could be because of the clean power: all are fed dedicated 220V 30A, 2 units are using EVGA 1600W T2, rest are on AW3++. Also keep the units low to the ground where the cool air stays, tho the garage stays around 90F+ (outside temps are 50F). Bitmain says operating temps max out at 104F, so fine solution until Spring/Summer.

Haha nice.

My A3's been acting up ever since day one and I think a hashboard just died on me. Temperatures are really low, with the outside cold the chip temps are ±60C. I see spikes in HW errors on all boards (bursts of 10k's of errors, leading to stale/invalid shares, and the one with the least amount of errors just left the building... Weird!

I would like to know if its really necessary to spend that much money for a EVGA or Corsair PSU? Does anyone have really better experience with non Bitmain PSUs?
thx

Along with Tekno2020:

Deleting and restoring from seed is a safe operation. There is no data loss as you have your original seed to recreate the wallet from. It's the same as restoring from seed using an electrum wallet.

hong kong is the country, not china. I had the same

I have 5 EVGA 1600 G2 PSUs and 1 Bitmain APW+++ PSU.
THe APW+++ is powerful enough and quiet to for any Bitmain miners.
The EVGA 1600 G2 has much better quality, and very quite. but it is too expensive.

Using the APW+++ PSU for antminers is the most economic way  IMO - but you would need 240V

[Neo-Geo]

I have EVGA 1600W T2 x23 units, and wish I had bought more back when the prices were $400 shipped for NIB and < $400 when used on eBay as it was an incredible value for having the best, but now they average $800 in today's market. The most I had ever paid for one was $409 shipped from Newegg, and they had no limit on order quantity. Lowest purchased was $340 on eBay for used. It's the highest voltage, highest quality, quietest, most efficient, longest warranty (10 year) computer PSU available. Also includes the longest cables (31") and the largest quantity of cables bundled with it of any PSU.

The AW3++ cables are too inconveniently short, and didn't even include a power cable, which is why I had to use EVGA 1600W T2s for 2 of the A3s on delivery day. Regardless, I would have used the AW3++ as I bought 1 for each A3, but I didn't have any c13 to c14 cables on hand, only had extra c19 to c20, and my town (Memphis, TN) and the surrounding suburbs don't stock such cables or adapters. I've since bought plenty of c13 to c14 cables from online. Using the EVGA 1600W T2 was just a temporary solution for the A3. Best if used for A3/S9/L3+ on 120V circuit or for GPU rigs. Eventually, I hope to see a 2200W T2 PSU (Titanium rated) from EVGA:

mine has one  

Can you please post a photo of where it's located?
it's definitely not the same as S9...
