Topic: [NEW] Bitmain Announces Antminer A3 - page 35. (Read 22419 times)
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
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.

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

Mines running pretty cool and I upped the frequency from 600 to 625 so getting around 867 GH/s - chip temp around 72 for high but outside air is good and cold as im up north
How did you set up the miner pools?

I'll be back in a bit I have to go walk my dog now

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 too much by selling the mining rigs, but I have a feeling that the mining thing in SIA will not have this high reward for a long time because the hashrate difficulty will be increased this year and the difficulty will be increased exponentially.
Anyone else notice their A3 running pretty hot on the chip side? Mine was approaching 90C on one board, had to go in and manually set the fans to 100%. Now running low 70's. This is with 70F ish ambient temps. These run quite a bit hotter than my L3+'s it seems.
ANY source to A3 firmware. Sadly after crashing need to flash my miners.
Would be grateful for support and assistance. Currently my two miners gives my total of 800Gh with only total 3 boards working

Doesn't matter just make sure that all ten are connected, i usually have a certain way of doing it as you have to have it turned a certain way for the length of the cords to work properly as it sits next to the miner, usually with the plug outlet facing the front and on same side as the control board plugin.
It does matter which way they snap in though, notice a little clip like thing on one side, you have to match those with the miner, when done right they will snap in place and then you have to squeeze them to get it to release.

As the difficult goes up the rewards go down. There is only so many siacoins rewarded a day and it has to be split between all the miners.
There is so many siacoins per block mined and it changes over time.

Switch pools , Sia Devs are at war with Bitmain , just like Dash
I'm on siamining... what other pool do you recommend?Jump to:
