[NEW] Bitmain Announces Antminer A3

[klwolf2000]

I ran my A3 overclocked at 930 Gh/s average for over one month with (low hardware errors under 2k/day per board)


I used 120V power on APW3++ and it worked like a charm!
Temperatures averaged around 62-65C for boards and outside room temps were between 60F-80F

I would say bitmain's PSU is stronger than it seems and does work well!

This is a dangerous example, since overloading the power supply may end up breaking it.

The input circuit in the APW3++ is designed to be able to handle max. 1200W at 110-120V and max. 1600W at 220-240V mains voltage.

I've also been running miner around 900-930 Gh/s (Overclocked from 600-650) and the power doesn't go above 1200W, it stays around 1180W on my A3's. Temps on boards are around 88C-93C with good air circulation and before at room temperature the miners would run stock at 80C-85C. After talking to Bitmain support the boards can run up to 115C before overheat protection kicks in but I would not like for the boards to get above 95C.

Ok if that's the case, then I stand corrected.

But it is close to the max. limit which the input circuit can withstand.

I think you mean those are for CHIPS temps, not BOARDS

Hi!.

How to get a power of 1180-1200W?. When I set the A3 to 650, my power is at about 1450W!!. Do you have an APW3 power supply?.

Did bitmain tell you that the board supports up to 115C ?. I think it's a very high temperature..

Anyway, when I put more than 640, it starts to give a lot of errors and the hashrate fluctuates a lot.

Best regards.

I have a problem with the brand new A3 miner. The fans power on, but there is no green nor red light, there is no IP, reset button doesn't work...I cannot do anything with it...is it a control panel malfunction or what? I tried everything including flashing via SD card and nothing helped. Help anyone who can

[AlexxB]

Hi there, there are 67 pages, I have read most of the at the beginning when A3 was announce.
I am asking someone who is willing to help me with an information, the question is simple:

Where can I exchange Siacoin to Bitcoin?

1) https://bittrex.com/ - Don't accept new members.

2) https://hitbtc.com/ - when trying to deposid SIA there is this: Please note that deposits are temporarily unavailable due to technical maintenance. Please accept our apologies for the inconvenience.

So it there an exchange that is working now to exchange Siacoin to Bitcoin?

Thank you in advance!

I'm using an APW3 power supply. What I did was overclock to 650 then after the settings are changed I rebooted the miner. When it first comes up I can see the power spike to over 1400W and then after a few hours it slowly settles in at around 1180W-1200W. Yes bitmain support said the chips on the boards are rated for 115C but from my background in computers I wouldn't recommend going over 100C. All miners are different but mine seem to like to be at around 650-662 which appears to be the limit of the boards because any higher they start to get lots of errors.

Hello,

In the last 24 hours, my reward has been 820 sia, with one A3. This is getting worse.

Well, I manage to create an account today but I am a noob when exchanging siacoin to bitcoin.
I saw this for tutorial https://www.youtube.com/watch?v=OX3Rod1ZKFI.
If anyone here has a noob tutorial video or text om how to exchange siacoin to bitcoin I would really appreciate it!

Thank you

[Miningtry]

I have opportunity to buy used A3, how much A3 makes these days?

[junkieforcoinzzzz]

Hi

Can someone tell me the stock heat readings for the boards/chips is for this device ?

I can run my l3+s up to about 75 Degrees - 80 without any issues (btw I am in Australia whatever)



So I am wondering what is the max safe reading you guys are running at the moment - People in sub zero temp environments need not apply

I ask as I plugged one these into the rig and would reach 100 quite easily and higher....Dont really want to turn it back on if that is normal....

https://www.shapeshift.io/ is a great site for exchanging Sia, good rates too, especially if you use precise.

Superminator is right, Shapeshift is super easy.

If you are looking to trade on bittrex it can be a bit confusing when you first start out but you get more confident in it. 

With shapeshift you can trade for whatever you would like that they offer.  In bittrex, you will be trading your sia for bitcoin...maybe ethereum (i cant remember if that is a pair off the top of my head)  and then you can trade that out to gdax or coinbase or USDT if you want for cash  (USD, EUR, etc.)

If you are just wanting another coin, then use shapeshift.  If you are cashing out.  use bittrex.

PM me if you need any help.

So...when I loaded my A3 out of the box it was pulling 820 - 900.   Did y'alls start at 600?  I thought the 820 was standard and it's been running fine no errors or drops.   It is loud as all get out though, blows the L3+ out of the water in terms of dB.  The power cord is warm too, it is generating heat way beyond the L3+.  I unplugged it once and touched the 3 prong and burned my hand they were so hot.

Also, there were pre-configured settings for mining using antpool  (this is direct from bitmain, not an third party or ebay sell).  Is this standard?  I don't remember that for the l3+

Using standard APW3  and I haven't touched A3 in terms of OC.

I I got today the first A3 with DHL, tomorrow comes one with UPS and one with  TNT.
All ordered and paid in the same hour.
The next day ordered A3 comes still on  Tuesday.

That's 4x A3 Yeah, I'm greedy.
But I also bought 32x D3 and one A5 (which does not work anymore).
3x D3 blades came from a warranty repair yesterday.

Little money comes with 47x L3+ and 6x L3 .
In addition, there is a gift from Innosilokon- one A4 + (Already mined 2.5 LTC. A long way  go to
10 500 USD, what i paid to Innosilicon for A5 and PSU-s.)

Total Litecoin miners Speed   26 000 MH/s , 3.5 LTC per day.
The money to pay for electricity comes from here.

So I  do not plan spend SiaCoin before soft fork.

1st batch had come out with 600 MHz frequency and they are indeed pretty hot my 5 pieces are running at 72-75 Celsius on boards and around 90 Celsius on chips, underclocked at 550 MHz
