ANTMINER U3 Discussion and Support Thread

[FluttershyRocks]

Hello everyone!  First time here, been mining with a U3 for about 8 months, and it's been working fine until so far.

I have been transitioning my miner to a small install of Ubuntu Server, and the first time I ran cgminer, the program and miner both worked fine and started mining right away at ~60GH.  I shutdown the miner to write a script file for the miner, and when I tried to restart, I was getting this:

Code:

 [2016-03-09 10:43:49] Started cgminer 4.9.0

 [2016-03-09 10:43:58] Shutdown signal received.

I am at an absolute loss for what's going on, I've gone from voltages from  0750 - 0850 volts and ANY frequency listed in the U3 user manual.  None of them have worked.  Any ideas?

You can't use Bitmains arguments(BMCS) to control the U3 with any version of CGMiner EXCEPT Bitmain's F'd-up Fork. If you want to run updated software then you need to review the included ReadMe file and script with the correct commands.

If you want to run updated software then you need to review the included ReadMe file and script with the correct commands.

And rather than 4.9.0 you should try using 4.9.2, it had updates specific for the U3 in it.  Do not use 4.9.1, though, it will not recognize the U3 (bug).

4.9.2 fixed the freq and volts for me. Only way I could get 60ghs was to use 4.9.0. And change the settings. Only zombies once in 7 days so far. Waiting on an antrouter to act as a controller as we speak

Make sure when you get the R1 that you get Crazyguy's custom software for it, makes owning a U3 rather enjoyable as it all but cures the zombie issues that plague these machines.

Already on the todo list  

On a different note I'm going to be hooking up the U3 to my PSU via a 6pin pci cable that I'm going to sabotage and connect to a barrel plug which has screwed down terminals. How many of the pci 12v and grounds would I need to connect? Two of each to power the u3?

PM sent, let me know if you're interested or not.

If not I'll keep the dead U3 around for a little longer before sending it to the e-recycle bin.

User jlauzon has not got back to me yet.  I'll keep the dead U3 for another week then it's off to the e-recycle bin.  If anyone else wants it, let me know. 0.03btc to cover shipping to lower 48 and it's yours.

One more week has passed and never heard back from jlauzon or any other user so the offer is withdrawn and the unit is off to e-waste.

Mike,
If you have not shipped it off to e-waste, I'll take it.

[Mikestang]

Mike,
If you have not shipped it off to e-waste, I'll take it.

I sent you a PM, I still have it.  If you are in the 48 continental states then it's yours for 0.03 btc.

I answered your PM.
I'll take it.
I'm in CA same as you.......

 Perhaps for less than .03 btc then?

 

[Mikestang]

Replied to PM.

Price is for a flat-rate medium USPS box, so afraid it doesn't get less expensive.

If you don't mind me asking, what are you going to do with it?  Who knows, maybe you'll luck out and it will work for you as mysteriously as it stopped working for me.

Initially, that's the first plan................

Second plan is to build something cool with it.


I got a Version 2 model from e-bay last month. Did not get around to setting it up until last week.
Had the "Zombie" issue at first.

Then found this thread on the forum. Started reading, on and off from the first page. Got to the last page this morning.
Learned a whole lot from all of you here.
 So. Thanks for that!

Anyhow. Tried some settings yesterday. And so far, knock on wood, she's been hashing away for 30 hours without issues. But at a low hash rate.
Will continue to tinker until I find her limits.

Well in that case what you really want in the bitmain R1 w/Crazyguy's software patch on it, that will basically eliminate the zombie issue.

Good luck with it, let me know if you are able to do anything cool with it.

[Swifft1]

You bet. 

Thanks again!

It made a big difference in my life before it I was using windows as controller.  I had zombies every morning and evening... so always resting then.  And during day they did it and I missed out on hashing time.   I was using 3 U3's and the R1 with crazyguy's mod made my life much easier.

I have a R1 again, just need get it set up.  So that is a project sometime this week for me.

does anyone have and used or new antminer u3's for sale? willing to pay $50 canadian each with shipping to toronto,ontario.

does not need to include the powerbar...thanks

looking to buy 5 of them...thanks

When you do get it going again come join the German R1 fun run, it's something to give purpose to the R1 besides using it to control U3.  Well, not much purpose, but it is fun at least!  https://bitcointalk.org/index.php?topic=1411813.0

I already got one... my old one in fact.   It's on my list of projects to get around to.  Thanks for that link looks like it could add some fun to it.  I have spent some of my hobby time playing with my drone lately.

Thanks to selling it via ebay/paypal is why I got it back.  Happy customer day 1 great feedback left about sale... and little less then month later he wanted refund.  I'm guessing he grew bored of it.   But it is almost scary how easy he was able to return a working device and keeping it and running for almost a month.

First miner I have gotten back via papal luckily it was a small R1.  I have been selling since A1 day's on ebay... guess I have been lucky to have gotten good customers in other sales.

My unit is always slowing down to 40-something GH shortly after restarting. Does it mean it'll die soon completely?

Doubt it without pushing them and using default psu that comes with them 40 something is not a completly uncommon number.  So I don't think it is a sign of dying personally.

But I could be wrong U3's... are interesting creatures.

Hi,

I'm wondering what pool I should best use with the U3.

Kano.is is saying I'm having dust payouts (list of dust BTC rewards < 0.0001 BTC) and don't reach threshhold to receive a payout? I don't understand exactly how this works, but I want to get paid out for my hashing power.

So what pool could you advise me to use or any other tips?

thanks!
