[NEW] Bitmain Announces Antminer A3

[Tssar]

Harper86 and Cryptonica helped me out getting a backup of the A3 firmware. thanks for that guys!   As others already found out as well: The A3 and D3 are very similar. I even found out that the software inside the controller chips on the hashing boards is exactly the same.
Out of curiosity I tried to run the A3 firmware on the D3 and the A3 firmware actually detects the ASIC chips and tries to  start mining on the D3 hardware. Looking at the logging it's fine, but it doesn't accept the work as Bitmain did actually changed something on the ASIC chips I guess. I do think they used the D3 as a base and stripped out 10 of x11 algorithms.

For now the conclusion is that you can't convert the D3 to an A3.
It probably does need reprogramming of the ASIC chips on the hashing boards itself.

Blissz please help us out with the A3 FW image you already have. Me and Tssar have the same problem (2 out of 3 hash boards not showing up). I tried everything, PSU, cables, turn on/off boards one by one, Factory reset, nothing helps. Before I open a ticket with Bitmain, Id like to try reflashing the FW as a last resort. That way I succeeded in revitalizing a D3 with similar hash boards issues a few weeks ago! On Bitmains support page there is no trace of A3 reference, manuals or files

Keep up the good work mate!

That would be helpful!
Thanks

UPS is asking for $72 import fee. Anybody else got the same?

All and all with my sound proofing box and such this ended up $3.3k. I hope I make it back lol.

Yes, I paid it too. I paid it twice for x2 A3. I have also paid for L3 and S9 as well, however its typically in 50's but for A3, its 72$.


On to different topic,

I just now plugged in one of my A3 in Siamining, Is there a option to set the payout threshold ?.

no, you will get firstly 500 coins, then payout every 6 H

Curious, they have so massive interest these days in altcoins and they decided to become unactive on this forum, just see bitmain's profile.
What do you think guys, does it worths to buy this miner? Maybe it's out of stock now, haven't seen but can buy in a good price.
Also what about price of those coins which are minable by antminer a3? Did their difficulty grew much these days?

Hi Abdulaziz,

Hi,

Would it be possible if you can share the A3 FW image.
We are 2 in this situation

Thanks

[Tssar]

Hi,

Can you assist us by sending the image of the A3 FW please

Hi, could anybody enlighten me if there is a working nicehash blake2b pool? It's not on the stratum list, tough in WTM its listed.

That sounds cheap to me... I bets its going to be more for me... hoping for friday

On NiceHash the blake2b is listed as Sia, since its the only coin minable with blake2b.  But i havent been able to get NiceHash to work for me....

I cant get it to work.  I got Mining pool hub to work for a bit, then it stops,  ie like 1 minute...

Funny how there is so little places to use this paper weight.. :-)

The network hash rate has doubled since yesterday, expect the difficulty to keep rising and the profitability decreasing as more miners join the network.  By how much its difficult to say as Bitmain has not released total units sold/produced.  Some estimates are that 10k units have been sold judging from the bitmain bch receiving address but this doesn't account for power supplies and other miners.

An anonymous guy told me 5k sold on day 1 (he was also right about the d3 fwiw)

If anyones interested on how my miner performed over 24h I created a video on it as well as the fork drama

I had this similar issue with a S(,  Unplugged the white controller cables, then plug them back in, on both ends, and the hash board that was not lit up, started to work..  Power off of course

[AerialGopher]

FYI  For anyone who considered Luxor.  I did, just to see, and the has rate was all over the place.  in 1 hour i got about 150 SC.  I trying siamining and in the last 10 minutes that I had this up and running there I am at 60SC already...  so..  you whatever they have the most hashing power, but there is a reason.

IF anyone has Mining pool Hub working, please let me know the settings you used.   I looked in the kernel log when it was there and I saw the error of Share submitted but it had an error..  I'd like to do that so I can get BTC automatically with the coin exchange they have set up.

Thanks

Still can't get it working.... ugh.

siamining is the only one working for me.

I think I need flash firmware of my A3 but I don't know where to get it :-(
How you get it??

[proteus7]

Same here. Siamining is the only one working. Not good, since they have over 51% hashrate. They also have a high 3% fee... Luxor, miningpoolhub, nicehash, etc all need to step up their game.

[redalert11]

Luxor works but they report hashrate every 4 minutes and total coins earned maybe every half hour.  Siamining shows you stats in real time.  Seems Siamining gets more coins per hour for me which is strange because my ping is 2ms to Luxor EU as opposed to 1000ms to siaminng.

Support me on the decred redit. Let's push the decred community to soft fork to defend itself against the obelisk dcr1 miner. The SIA development team have proven themselves untrustworthy. Who knows what they will do with all that decred asic hardware?! They will probably 51% attack the network! I heard that they sold 1 million miners!

1 million miners! yeah that doesn't sound credible.

Hey, a guy said it. It must be true. Just like how siacoin community believes that bitmain produced 100,000 A3's. Some guy said it, must be true. Let's work together to defend decred from obelisk!
