ANTMINER U3 Discussion and Support Thread

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!

[winspiral]

perhaps bitminter...
I think about giving away my bitminter account with a little dust on it.

oupsss I believe it is not possible...

If you've only got  U3 then that's all you will get. I use bitminter for all my miners (2xS3+ 2x U3 and 1x gecko stick) and only make about 0.07btc when a block is found. I get that much because the pool hashrate is around 3500ghs-4000ghs whereas kano.is is 30,000-35,000ghs so your earnings are small by comparison. The onlhy thing with kanos pool is that the payouts to your btc address are as soon as the block has been confirmed, whereas bitminter you can set a minimum payout amount which gets sent out as soon as its been reached, effectively like a bank account, it will store your earnings until the threshold has been reached.

But bitminter don't get as many blocks as kano, but the payouts are larger, so it kind of evens out really, just aslong as you don't mind waiting.

I wouldn't have asked if it had been working this way from the beginning. But it has been stable for several months at about 55 GH using an ATX PSU and default cgminer settings. I hope that's only one chip malfunction out of 4 and not some general degradation or something.

What do you mean? That I will never get payments with any kind of pool if I only use 1 U3?
Thanks for the tip! I have now set Antpool PPS as mining pool. What do you think about that one?

with a single U3 you'd better try your luck at solo mining (what I do with my 3xU3)

kano.is doesn't pay under 0.0001BTC earning, so basically anyone with under 140Ghs with pool hash at 35Phs doesn't get paid

(35000000*0.0001/25)

Is there a pool that pays when you use a low hashrate miner? Like Antpool PPS,  do they payout when you reach 0.0001 ?

Eclipse offers PPS, but im not sure what the payout threshold is for them. Should be quite low as I tested an Antminer S1 on there (underclocked ofc) and I got paid with their PPS. They aren't a big pool, but they do have pretty good rates.
