ANTMINER U3 Discussion and Support Thread

[Speedster1978]

Just a preliminary post, "BUT" I may know why these things aren't hashing correctly and I don't think it has anything to do with the chips or power.

Can you give us more information?

[dogie]

Can you apply more then one coupon to an S4 order or just one? With this coupon, instead of $1400, it would just be $1000 right?

Just one coupon per S4 order.

[Nightshiftgirl]

Dogie,
 Is that one coupon per S4 or one coupon per total order?

Try this:

Code:

cgminer.exe --bmsc-options 115200:0.65   -o xxx -u xxx  --bmsc-voltage 0800 --bmsc-freq 1306

Using these settings raised my GH/s from 40 to 50 but now I am getting large number of Hardware Errors saying Invalid Nonce.  The vast majority of all frequency settings spit out this same error except for 0755 voltage 0782 freq and 0755 voltage and 0882 freq, but I only get 30 and 40 GH/s on these settings.

Also, I haven't been able to get it to run for more than 12 hours without going ZOMBIE or just sitting there hashing at 250 MH/s.

Any ideas before I just get rid of this thing?

EDIT:  Lasted for a whole 7 minutes at 50 GH/s, now is ZOMBIE.  Going back to the 0755 setting for a whopping 40 GH/s.

Hi, asking for some help getting my two new U3's up and running.

Using this guide:
https://www.bitmaintech.com/files/download/AntMiner-U3%20user%20guide.pdf

Running on W2K12R2 on ZBOX ID84 Atom CPU, bitmain cgminer does not detect U3, seems to be a timing problem.
Same machine running official CGMiner 4.7.1 using old USB blockerupter works fine.

Running on Win8.1 x64 on Corei7, bitmain's cgminer-run-windows-20141027 detects U3, but keeps reporting "Waiting for work to be available from pools".
Debug log shows the real error is "JSON stratum auth failed", "Method 'mining.extranonce.subscribe' not found".
Log here: http://pastebin.com/gqrN6RmK

Using the real CGMiner 4.7.1 and the old blockerupter works fine with stratum.antpool.com and with stratum.bitcoin.cz.
Seems to me that something with bitmain's 4.6.1 based CGMiner and the stratum pools don't like each other.

Any ideas?
P.

Try this:

Code:

cgminer.exe --bmsc-options 115200:0.65   -o xxx -u xxx  --bmsc-voltage 0800 --bmsc-freq 1306

Thank you, This seemed to fix the GH/s issue. Now my U3 is mining around 61Gh/s. Now i need to figure out how to get multiple U3 miners working in one cgminer. Somebody suggested that once cgminer is running with one U3 just keep plugging more miners and it will detect them. It is working like this for about 5 to 15 minutes and then in random order they will all turn ZOMBIE and can not initialize incorrect device. So i unplug the ZOMBIE miner and plug it back in and it will recognize it and start mining, but soon after it will be ZOMBIE again. I have connected four U3 miners and i can mine only with single miner. If anyone has a tip or instructions on how to mine with multiple miners or how to get rid of the ZOMBIE issue please let me know.

I only have ZOMBIE issue when i plug more than one miner to my usb hub. Then random miner will turn zombie. Wierd, seems like software issue not hardware issue, Maybe weak power supply? not sure

[zsmith]

I just have the one miner hooked up to the computer's USB port.  It has never lasted through the night, every morning it is no longer hashing.   Other than today, it's only went Zombie one other time, usually when "it's not hashing" it just sits there showing 120 MH/s or 250 MH/s on cgminer and zero hashrate at the pool.   

Between all the downtime and the low hashrate, I'm averaging 18.33 GH/s per day on this device.

I agree that it sounds like a software issue.  I think the driver and/or the cgminer fork need more work.

EDIT:  Just went ZOMBIE again, right after I made this post.  Restarted cgminer and it never found the device, restarted computer same deal.  Changed the Baud rate from .65 back to 1, ran cgminer, still nothing.  Pulled USB and Power Cord then plugged power then USB back in, ran cgminer again, now is hashing back away at 40 GH/s.   That lasted about 10 minutes.  For some reason, ever since I changed the settings to 0800 and 1306 and .65, it won't run for more than 10 minutes without going zombie, even though I changed the settings back to what it was sort of working on before.  I've just unplugged the miner for now.  I'm going to try and install it on one of my other computers tomorrow to see if that makes a difference before I give up on this device and Bitmain forever.

another thing i forgot to mention that you could try is got to control panel > power options > change plan settings > change advanced power settings > USB settings and make sure that usb selective suspend is disabled. See if it still goes zombie.

[zsmith]

Thanks I changed the setting and it is running (so far), I'll see in the morning if it is still running, if not I'm doing a fresh install on another PC.

[And1129]

I just got mine ordered off eBay too and i'm having difficulties.  I was able to get and correctly install the right drivers, but still haven't gotten it to work. I see the command line going around has helped a lot of people...  I hate to ask a total n00b question here, but how and where do I go about entering that command information in CGminer?  I'm not too families with theses things yet, but I've been learning a ton lately and have been controlling my other usb miner with BFGminer on Slush.  Any help greatly appreciated here.

right click on cgminer.exe and go to Create Shortcut

right click on the shortcut, and go to properties

Go to the shortcut tab, then where it says "Target" put in all the info such as pool name and config parameters.

Instead of cgminer.exe - Shortcut, I set mine to be "Cgminer.exe - Pool Name" so I can have a shortcut for each pool I want to try out

Bitmain's cgminer can be downloaded here https://bitmaintech.com/files/download/cgminer-run-windows-20141027.rar it is the only mining program that supports U3 at the moment. Once you extract the cgminer, make TEXT FILE in that folder and rename it cgminer.bat then right click on it and choose edit. then copy and paste this command line there (cgminer.exe --bmsc-options 115200:0.65 -o POOL:PORT -u USER -p PASS --bmsc-voltage 0800 --bmsc-freq 1306)
Ofcourse change the POOL to your mining pool PORT to the pool port USER to your username in that pool and PASS to the password. Start cgminer from the newly created cgminer.bat file. It will run the command and start mining.
Let me know if that helped

[And1129]

Hey guys, thanks so much for the help. I'm not there yet, but now one step closer in the right direction. I created the .bat file, but then i couldn't get CGminer to start from it (open the .txt file with CGminer?) Then, i used that code to try the shortcut method again, and it worked this time!  CGminer opened and responded, but it still isn't hashing. It seems to be caught in a loop where it: sends votage, ok, send golden nonce, bmsc golden nonce timeout...other stuff spaming... then
Bitmain detect <5:3>  failed to initialize.<incorrect device?>

So still nothing. So far i've only tried it with Slush's Pool and a few other here mentioned having issues on Slush with this as well; might that be it?  I'm done for tonight, but i'll be back at this tomorrow!  Thanks for the help so far.

I wouldn't recommend this for others just yet.  Also if anyone knows a better one to reach what was promised please let me know but for now this is stable.  I will attempt to post video's and Picture's tomorrow to show what lengths I had to go through to get this to work.  Granted the base components are 1x120mm Fan, 1 Gridseed Power Connector, 1 "Cincinnati Tool CO."

Also if Bitmain has anymore then just coupon's that I can't use to give me, please let me know.  (I don't spend BTC for mining equipment...  USD ONLY....) to add please do?  Also added name here to name there.  I got 1 from minersource.net.  You will see what I want to order in my cart.

When is Bitmain going to merge U3 support into the main CGMiner? The CGminer that supports U3 does NOT work with my Rockminer!

As per all previous bitmain hardware, they have slapped together a driver as quickly as they possibly can making for a mess of code that doesn't merge into mainline cgminer, and they haven't approached us about either getting our help, merging their code, or providing hardware for us to fix the driver for them. Someone else will probably send us some hardware and we'll eventually write our own driver is what normally happens (and bound to happen again).

[BITMAIN_JLXUE]

Not sure if this is the right thread for this anymore...

I got CGMiner compiling on OSX and per the suggestions above for settings ran it with:

Code:

./cgminer --bmsc-options 115200:1 --bmsc-voltage 0720 --bmsc-freq 0782

And this is the output:

--bmsc-freq 0D82 is setted at a large frequency. You shall modify '0D82' to '0982' which is the max frequency for U3.

[BITMAIN_JLXUE]

This is pathetic! I can't believe Bitmain would release a product with no solid instructions or mining software to support it.

Maybe if we all email bitmain asking for an Rpi image for the U3 that works they would post one (and for anyone not planning to use an Rpi we could always deconstruct it if we know the cg version used).
I have tried everything I could think of using the settings designed for the new chip. I am now going through options settings for the old ones to see if any work (i.e. icarus options with amu setting etc.)
 So far no luck with anything.                                        

Waiting on engineer (currently 8am).

Hi,

Pls try to install USB driver again referring to manual https://www.bitmaintech.com/support.htm?pid=007201404130632574925y76a4v50657
Make sure you select CP2102   USB.
