Tôi không hiểu thuật toán mà nó sử dụng, bất cứ ai có thể tìm thấy nhiều thông tin về nó?

Hello,

What strategy are you following with sia coins?, are you holding them or are you trading to BTC?.

Best regards.

Holding for now
Really not selling any but I think my ideal strategy will be hold a percent,  swap some for other coins to hold to diversify, and sell some to pay for mining power ...

Hi!, your proposal is interesting. I have everything still in altcoins, but I think that we would have to sell something to make a profit and pay for mining power. What method do you use to convert it to USD?

Regards!.

Depending on where you live an exchange like Kraken or Coinbase (GDAX) would be an option for trading fiat currency for bitcoin and selling bitcoin for fiat currency.

Hi guys,

I ask again, could somebody with a D3 be so nice and post
a hex dump of the PIC16F1704?

Thanks and bye, FNT

Send me a link with instructions on how to make the dump and I'll get it for you. I have 2 D3's and 6 A3's. I also flashed the D3's with the firmware for the A3's and after a few minutes the board went to all XXXX. I ended up flashing the D3's with the blissz firmware.

Inform me on success

Can this unit be ran on 110v power with a 1600w power supply?

If it's the Bitmain APW PSU, then the simple answer is NO.  Not unless you want max out the psu and potential burn your unit down.  It will run, I tried it for a couple of days... but the hash rate and amp draw will be swinging all over the place.   For a stable draw you need a 220v circuit OR a PSU rated to deliver 1400W+ at 110v.

Don't risk it.

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!

930 GH ?!?

Oh my God, you sure? What frequency you use for it? Mine are running at 550 Gh with 90-94 degrees Celsius on chips and 70-75 on boards.  It's true, it's a pretty hot ambient too.
But 930 Gh.....

Boney, can you please share your configuration

Also, the firmware that the A3 has, does it have the option of adjusting the speed of the fans?
the S9 does not have it but in S3 & S7 the option exist

thanks

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

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!
