ANTMINER U3 Discussion and Support Thread

[imap30]

Hi. I purchased 4 au3 miners off of ebay. The dude I purchased them from hated them so much he gave me 7 even though I only paid for 4.

I need two power adapters. Where can I purchase the power adapters?

Also. Your miners are stupidly unstable. is there a firmware update I can do to make them stable? They can't even stay up a whole day with out turning into a zombie...

hello

thy're no "our" miners

you'll have to learn to live with it, or just read through the thread to see the few solutions available.

You can power them using a PCI-E connector.

And if become grumpy and unhappy, I'll buy the 7 for the price of 3 

Where can I get that PCI-E connector?

Google antminer u3 pcie connector or try ebay, or make it

How much did you pay?  I cant imagine giving 3 extra's.

You can look into linux and scrypting (such as RPI) to reset.  Or easy is get a R1 from crazyguy with custom firmware - https://bitcointalk.org/index.php?topic=612390.0

Either one is a valid way to fix zombies.

It bothers me though if it is safe to leave it for a long time unattended. I mean, can it possibly fail so badly that it catches fire and burns the apartment? Do you guys take any precautions just in case?

Once they zombie out I think they are harmless.  Although I have had two molex plugs melted by a U3 and it wasn't even overclocked very high...

I didn't rely on the solid red LED up front because sometimes when it went zombie or simply went to a zero hashrate;  the red LED was still lit solid....

Mine was pretty accurate with the red light.

Mine have also been accurate with the red led, it always shuts off when they zombie.

Welcome to the U3, this is how they operate.  You'll be lucky if you can get more than 1 to work at once, also, good luck!

What would you consider a good miner? I only want to spend $100-$200 and would like to ditch these au3's for something that I can turn on and forget about.

You're pessimist Mikestang

I have 6 on my RPI

Block erupters are ok, and for 100$ you can get a bunch

Mikestang is a realist when he says they suck. Based off what I am reading the au3 is the only miner anyone really has any major complaints about. Wish I would have spent a lot more time than I did researching them before I purchased mine. The purchase would have never happened.

[zOU]

I'll buy them off you, 100$+shipping to Europe.

So you don't lose any money

OK what am I missing here? Even if you have 20 Block Erupters you still only have about 7GH/s consuming around 40 Watts. Why would anyone want that when you could have a Compac or R1 with a higher Hash Rate, 1/10 the Power and less money?

That was sarcasm

Makes a lot more sense now you put it like that....

Get an S3+, it will do 450-500GH/s (depending on clock settings) rock solid for ever and you won't have to do anything for it.  They are right in that price range, including the psu (I have one for sale for an S3 if you need one).

If you want to stay with usb miners then get like 4 compac sticks and run them 15-20GH/s each.  They are great little miners.

I use mine for lotto miners just for fun.  A S3 is a tad big for me on lotto.  I don't like paying electricity very much on lotto miners.

So I have 3 U3's and 7 compacs that make up my lotto miners.  They are working great as of now.  Rest of my miners all mine on pools.

Is there any software I can run that will reset my miners if they go zombie?

CrazyGuy's R1's if you select it come with a custom firmware that does it.

Other's have mentioned a chron job on here (I believe it was crazy guy who put it up, and others just quoted).  But that is other option.   This one I have not seen as much about people doing so might be some more work, but should be doable.

Can I plug 7 u3's into one r1?

[notlist3d]

Can I plug 7 u3's into one r1?

I have done 3 without any issues.  I have not see 7 on it.... but I think it should be able to do it.  Only thing I might suggest is looking at CrazyGuys with the auto zombie fix.  With 7 it will be more important I would think.

Or write your own mod to do it.   But I'm going to say it should... but 3 is my max so I could be wrong.

does that router have a user interface? if so, how easy is it to access?

[notlist3d]

Yes it has the GUI you would expect from a bitmain product.  It feels like any other product they have.   

The main differences I can think of with CrazyGuy's versiion vs original is the zombie fix, easy gui freq on internal chip, and being able to point internal chip to pool of your choice through gui.

But yes very much GUI and easy.
