Yes but you are using 2x PSUs without power distribution. So you have 1 PSU connected to 2 boards, which could take up to 1050w. 425w is not necessarily enough to boot up 1 board if they are specified 525w each. I have power distribution circuit boards, so I can use 2 PSUs on the same board..

Try disconnecting all hash boards, and only boot up the control unit only. Then configure to low clock, then re-connect everything and power on again.

But if you mean blank, as in White page, no menu, can't click Configuration at all, then it sounds like you lost your firmware.
If so.. Then no clue what to tell you... Can you get SSH access?? If so then possible for someone here to send you a copy of the firmware if you trust it for no viruses .. LOL

Bitmain has not posted a copy of firmware yet...

Just thoughts

Nevermind I just re-read that. I see what you mean about the PSU not being enough.

We do have a Bitmain Apw PSU, but we're running 120V.

How would you recommend utilizing 1 Bitmain PSU and 2 850W PSUs to power this thing at 120v?

We're using 2x 850W power supplies.

I can't even get to the screen to adjust frequency, with everything blank on the main screen.

I don't think 850w is enough to power 2 boards. I am using 2x 750w supplies, but also using breakout boards to manage power distribution and fault protection. Hash board #2 is being powered by both supplies. But a single board can draw up to 520w according to specs. So try underclocking to like 350mhz, get it to boot up, then move up until you find your highest stable level.

Hi guys, can use some opinions on why my A3 is not working. Situation:

I purchased a few A3 and set them up at home. Had a hell of a time figuring out the "No Socket Connection" errors until I determined that SiaMining was the only thing that got it to run. At home, I run 240v and they were powered on one Bitmain APW3 PSU. Ran beautifully.

I sold one to a friend. He set it up with the following:

120V
2 850W power supplies (1 powering 2 boards, the other powering the main control board and the 3rd board)

No matter what we did, we could not get his to mine. We tried all of the following:

1. Reflashing the firmware.
2. Giving the miner a static IP address on the network
3. Multiple reboots
4. Multiple Resets to default settings.
5. Unplugging and re-powering

After the static IP failed to work, I tried to revert it to a DHCP Ip address, and here's where we are now stuck.

Now, the miner shows me nothing on the General Overview Page. Everything on that page is completely blank for the System fields, and all of the Memory status bars are at 0. I tried re-flashing the firmware again, and still everything is blank, and I cannot even click on any other tabs within the antminer menu. I cannot click on Configuration, or Status, or Network.

He lives in a colder climate and just got the machine yesterday, so I told him to unplug it for the night and let it get to room temp indoors before we try again. As we were troubleshooting, the A3 was on high speed with the fan, so I am wondering if it was overheated after being delivered in the cold.

Any advice on what else to try is extremely appreciated.

thank you so much for your reply! I'll go to siaming

They never found a block, and they pay PPLNS, that means they never paid anything. I think their pool is broken. There are currently 3 pools that work with the A3:

https://www.f2pool.com/
https://siamining.com/
http://mining.luxor.tech/

The three of them pay PPS with 3% fee. I recommend siamining, but you can choose the one you like.

yes, I'm using antpool.
but why I can not use it?

You're not using antpool are you? Use siamining

Guy, can anyone tell please whats happened?
my a3 works all nights, everything is ok but still 0 in a balance.
what's the problem?

Those are great "space heater" settings, actually. Keeping them for when the A3 becomes barely profitable, thanks!

Underclocked today to 350mhz.
Power consumption 3A @ 240V (720W) (-50%)
Hashrate 520Gh/s (-35%)
Ghs / Watt 0.72 (+21%)

Default settings:
600mhz
Power consumption 6A @ 240v (1440W)
Hashrate 810Gh/s
Gh/s / Watt 0.5625

The display error was just with using the search function to view your account. I've been mining there for almost a week with no issues on that end (you can just paste your wallet onto the end of the url for the same result).

My only problem was a payment that didn't go through but that turned out to be solved by doing a recovery of the wallet (rescanning the blockchain). Luxor wasn't super helpful on the support end for that, but the coins weren't lost so I'm not complaining...

619 @78% fan for me. Runs smoothly, not TOO loud (over 85% and the vibrations come through the floor), and temps all in the low 70s.

i had it on luxor several days ago but then they were having some display error so i switched to siamining - but it seemed luxor was producing more.  i'm averaging 825gh/s on siamining and getting 51 sc per hour/ 1,457 sc for last 24 hr.  what are you getting on luxor? 

Yeah I pulled back down to 650 after my crash at 700. But I am running 650 and now only 69C on hottest board.

One of my hashboards crashed at 600mhz running at 77C after about 8 hours. Hashboard came back after a restart. Moved both machines back down to 550mhz.

77C is NOT stable.

Now running 65/64/71, 62/64/65 at 550mhz with 95% fan. Stable so far.

Yeah I not had any X's or -'s or anything other than 0's in the status area, but I am only counting 57 ASICs on chain 3, and there are 3 missing 0's. Sometimes I get CRC errors in the log on bootup, and have to reboot a few times to get it running. Hopefully it lasts long enough to pay for itself.

Started playing around a little this AM myself. At default freq and 95% fan the 2 outside boards are the same temp for me. 76/69/77 & 75/68/76. They're just not getting the same amount of airflow as that center board. It might be more effective to take these things out of the case and get better airflow over all boards. Should be possible to get the temps down to reasonable levels at 600mhz.

I'm thinking, custom case to house the hashing boards.

Aye, high temperature is the enemy of electronics - about a 50% reduction in lifespan for every 10-11C increase in temp - but an ASIC miner is only cashflow positive for a few months anyway, isn't it?
