[NEW] Bitmain Announces Antminer A3

[frands1]

anyone have a guide out there on how to connect the APW3++ to the miner?

The PSU has 10 heads. 2 groups of 4 and 2 individuals.

 

Every video or tutorial I've found skips right over this. I'm begining to suspect this doesn't matter? just connect all 10 connectors and go?

Yes I had the same question, then I followed each cable and realized all of them are connected together anyway...
It should not matter at all.

The issue is when power comes from 2 different PSU

things seem pretty steady right now, since the short crash yesterday. Here's a snapshot of my 24 hour stats at siamining, you can see when i plugged in the second miner is when the crash happened and it dropped to half the hash rate for 30 minutes or so then back to normal.

Hopefully there is a proof that shows the real work that the Bitmain Antminer A3 does, and based on this screenshot it means that 14000 SIAcoin is around 566 USD which is really really good, and I think that you will reach your ROI in few days (or within the first week, most likely).
I missed the A3 Antminer and I still can't find anywhere to buy it, I understand the sellers that don't want to sell because they are loosing

thats about right. i'm getting abit over 7,000 sia daily from each A3.. you can see from the screenshot. he has 2 A3 connected for a total of 14,000sia/24hrs.

I had some trouble connecting and finally figured out it was from the wallet address, it was not working with the Bittrex wallet address for me so I ended up downloading the Sia wallet and used the address from it and it was easy after that.

[Marvell2]

why does the sia wallet generate a new address every time ?

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!

Any luck to have FW. Having same issue as above.

If you're seeing much higher than 11A power draw at 120V, check your power cable, make sure it's not getting warm. One unit drew 14A on an 18 gauge cable, causing the cable to get a little warmer than i was comfortable with. Switched to a 16 gauge cable and it dropped to 11A and the cable stays cool.

Guys if Sia decides to softfork it won't happen overnight, it takes considerable thought and planning.  This is decentralized storage  user and company files are at stake, there needs to be consensus.  Sia is not gonna just flip a switch and softfork.  If they do it will probably take a couple of months at least. 

Yeah, I think the fork rumors can stop now. Sia announced earlier today that they will not support a soft fork at this moment in time as they believe it will damage the Sia reputation and community:

Yea, its not happpening, but SIA has acted like a bunch of douchebags in this mess.... I understand how much they have invested in it....  But it was a bad play from the beginning.  They don't own the coin outright, so how could they expect it to remain untouched.  I mean, they support ASIC mining over GPU's unless it hits their bottom line.  Oh well... I gotta go read about this difficuly fork at block 139k and see its impact.

For the Sia wallet under receive siacoin tab you can save the address and gave it the name A3 miners or similar so you don't lose it or get it confused with different address

Network hashrate has gone 4x since I plugged my miner in 2 days ago.  Profitability going down by the hour.

Is there a way to configure a3 on nicehash?

Hi,
I connected mine on miningpoolhub and get that :

How come Im only at 123 GH/s?

Go to miner configuration and click on the advance settings tab and then chose default from the drop down menu.

You're frequency is way too high

I noticed the same.

Anybody out there overclocking? wouldnt this be the best time to do it since payout is higher? does it void warrranty?

I have mine set at 625 mhz with highest chip aroudn 80c and about 100 hw errors an hour.

Might bump it up a bit when I get home.

Payout is higher and it does void warranty. So it's really just the question if it's worth it or not.

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

Actually, I'm doing fine with only 1 APW3++ with the Antminer A3 on 120V.
Right now is consuming 11.54 AMPS and 1337W.
No issues at all.

Thanks for sharing.

Why is it so different for everyone? Some posting 1500 W and some 1400 W. Will power cable guage matter? Like 14 AWG pulling less power than a 16 or 18 AWG? Might sound silly. But what else could be the reason. They are not overclocking though.

A friend has it running at 656MHz @ 301GH/S with 0 HW errors. But beware, this thing is heating up like hell. Good thing that its winter here Also at that speed the 1600W rated APW3+ is at its limits! And yes, you are voiding your warranty so dont do it

One unit drew 14A on an 18 gauge cable, causing the cable to get a little warmer than i was comfortable with. Switched to a 16 gauge cable and it dropped to 11A and the cable stays cool.

Might sound silly. How does the AWG of power cable impact how much it pulls? Will 14 AWG be even better and will pull lower than 11 A?

Not doing it, just asking for a friend...
So, the minute it goes over 600 the warranty is gone? if that's the case, then no need to look back lol

Thanks for sharing your opinion...

btw, 301GH/s per board or you meant 901?

Ok thanks, it's better now, 329 GH/s in average. However, it is far from the  800 GH/s announced.. any idea how to get there? Should I just wait for the miner to slowly grow to 800?
