[NEW] Bitmain Announces Antminer A3

[redalert11]

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!

https://www.reddit.com/r/decred/comments/7st4fw/obelisk_51_attack_is_coming/

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!

Just because some guy said it doesn't make it true, you need hard data before you can make such an accusation.  Also isn't obelisk working with the Decred dev team? why would they attack their own livelihood?

Apparently that's not needed at all. Just look at SIA devs developing softfork, testing it out, and taking miners offline in the process.

I don't know if they're working with them or not. What I do know is that they've made mud slinging, complete fabrications, and protecting their own profits acceptable. So, that's what I'm going to do. I will mud sling, fabricate, and protect my profits just as they are doing to me. If that means fabricating bullshit about their other product to put them in the same position they're putting me in, so be it.

I'm using 3 power supplies to power a A3 using 120v power.  The miner takes almost 1500 watts using a watt meter.  

What? No. I'm using 1 APW3++ using 120v. No issue at all. Consuming ~1,200 Watts

[Darknicks]

My antminer A3 arrived one hashboard dead .
1st time I plugged in,One blade is dead.
PLEASE see the picture.

then

and
http://fantom.tokyo/A31DEAD.PNG

so I switched 18pin cable connection 1and2 and still board1 is dead(this time board1 is chain2)

So please give me advise:-(

I think you just were mining during the soft fork test. Try rebooting your miner. It should be fixed by now

well wtf I must have just wasted a ton of money buying a second PSU because I thought my miner would have many hardware errors and screw up from being on 120v

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.

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.. :-)

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

siamining is the only one working for me.

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.

Luxor is working for me now.   They bumped up the starting difficulty (8k for me on the us-east server) which seems to resolve the issues but its settling at ~800.  MiningPoolHub is still starting at a difficulty of 1 and the miner gets crazy with the HW errors and restarts.

Someone posted it is taking as much as 1500 W. What is the real truth?

I am in the same problem too. 120v and planning to use 2 power supplies.

[proteus7]

Its reading 5.9A at 240v at the wall, so 1416w with an APW3++ power supply. Its also mining a little faster than usual at 835GH, so that may be why its high.
At 120v, it would be pulling 12A..so better have a dedicated circuit for it!

Yeah, dedicated circuit is not the issue. APW3 not able to provide anything more then 1200 W on 120 V is the issue. Thats why I am planning to use APW3 and another EVGA  750 W PSU to power a single A3

Hmm anyway to setup a solo mining situation?  that way you can control your own diff.

Guess you could always underclock it to a lower frequency on a 120v to reduce wattage draw, and run it off a 20 amp circuit

I am having the same issue with 2 boards. The reset and the reboot didn't help.
The only solution left is to flash it and we need the help of the A3 community as on Bitmain website they don't have it available....
I have asked for support waiting for a miracle to happen :-)

Never had a bitmain asic before. Is it simple? Do you have an A3? Can you share what exactly to change bring this to 1200 W? Will that void the warranty or any other potential damage to the device? I understand that it will bring the hashrate down. But will avoid many issues for me.

[Moon2eth]

Bitmain specs say 1186 +/-7% fluctuation at 12v DC. Simply do that and add your psu's efficiency. 7% for titanium, 9% for platinum, 11% for gold and so on.

So the max it should draw is 1386w if you have a platinum psu. Psus also operate slightly more efficiently at 240v than 120v by 2%ish.

If the operating temperature is really hot I could imagine it going up to 1500w. 1350w is a more realistic day to day scenario.

[abdullaziz.said]

To those that have started to mine.

How much watts is it pulling? Any chance we could just run the APW3++ run on US 110 V?

APW3++ only 1200 watts on 110v. Even if bitmain overstated the draw, which they usually do....you would be cutting it awfully close.

Can someone post the power consumption details about A3 please? Really curious about a possibility to run Antminer A3 on 110V using APW3++....

Tested with 240V. Power is 1450W on wall

 On stock clock

Holeeee shit. Seems like they overclocked the shit out of these things. Just like the D3. What Frequency do they run at to get the 815mh??

Frequency running at 600.. temp is good, very stable miner..

What pool are you on ? How much is the miner earning per hour. Could you please share the configuration page, graying out confidential information. Thanks.

my pool is siamining.com
this is my configuration

Hey dt, what power supply unit are you using and are you on 220 or 120 volt?

i'm using this one https://shop.bitmain.com/productDetail.htm?pid=00020171107201722598O4kMWe280658
and i'm on 220V

I have a meter on mine too on 120 V, and its 1400 Watts at the wall!

I have also had 5 s9 antminers drawing 1525 watts on 120 volt the same way for over a month..  on the same PSU's   APW3++

I read its not safe to do that. APW3 can only provide 1200 W at 110-120 V safely. No?

Anybody else experience a collapse in mining speed / ASICs going offline this morning around 00.30 EDT? Looked the same as the dip the day before and I can see it in the global hash rate graph on siamining as well (smallish compared to earlier).

After a reboot all was fine again. Maybe my A3 crapping out or ... ?

[hellscreamer]

Switch pools , Sia Devs are at war with Bitmain , just like Dash

can you help me with your A3 Archive? I have 2 dis-functioning hashboards
