Topic: Antminer u1: BFGminer: How to set up to mine Bitcoin (Read 46120 times)

this thread is a bit old, but I'll try my luck. I recently bought a used Antminer U1 (v1.1), but I have trouble to get it to work. I'm using the latest bfgminer version compiled on a cubietruck under ubuntu 14.04.
There were no compilation errors, and it starts just fine, but it just can't find the Antminer.

Judging by dmesg, the device should work:


Do I need a powered USB hub? I'm not trying to overclock, I just want it to work. Any suggestions?

EDIT: I just tested it under windows, and the miner works out of the box. So, I'm either missing something, or it's really a power issue?
EDIT2: It's not a power issue. I just tested cgmier and it works without problems. so why can't bfgminer find the device?
EDIT3: it works now, had to run with sudo -.-

Looks like you only have one - at the --set-device part, it needs to be 2 -

bfgminer.exe -o stratum.bitcoin.cz:3333 -u AK47OK47.NUMBERONE -p P313135 -S antminer:all --set-device antminer:clock=x0781

Use the drivers from this page, along with latest BFGMiner

http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx

From the looks of it its a driver issue. Which windows are u using? I have been more successful with cgminer on windows and bfgminer on minepeon but everytime the device is not recognized it means a driver issue. 

Hello yall!!! I'm really really new to the Bitcoin world!!

I am stuck.....

I have a Dell inspiron 15 laptop with Core I3 processor. I have a sabrent powered 13 port USB hub connected to my laptop via USB, with 04 Antminer U1's in it with the artic breeze fan on top of those.

Here is my issue....

I have tried CGminer, Guiminer, BFGminer.... and I cant get any to work..... I have no clue what im doing wrong....

I read this and, yes it is very helpful, but I cant get it to work... I tried changing drivers, changing around words in the bat file...

speaking of which this is what my BFGminer bat file reads... any problems? guess Ill start here and work my way down the list....

bfgminer.exe –set-device antminer:clock=x0781 -o stratum.bitcoin.cz:3333 -u AK47OK47.NUMBERONE -p P313135 -S antminer:all

I have also put in...

bfgminer.exe –set-device antminer:clock=x0781 -o http://api.bitcoin.cz:8332 -u AK47OK47.NUMBERONE -p P313135 -S antminer:all

and nether one work..... SOOOOOOOO..... any advice??

note*my password isn't really that one above....

I wanted to know how to remove the win32 Driver

Actually I have a question, since my first U2 is arriving tomorrow and the second should arrive saturday or monday I will soon be setting them up, and I have found several guides now that differ on the matter of clockspeed:

My current understanding is that:
The original U1 was designed to run at 1.6 GH/s and should do so fine without any additional cooling needed.
The U2 basically is a modified version with improved cooling and some adjustment on the two R1 and R2 things (whatever the are I am no engineer and have no idea of such things) that allows for overclocking up to 2.2 GH/s and should run fine at 2 GH/s without additional cooling (at least some product descriptions in shops say so).

What I could not get a definitive answer to is at what point of overclocking will I need additional cooling?

Also all threads/posts/articles I've found allways speak of the necessity of a powered hub especially when running several U2's on the HUB. That makes sense to me. But what about running just two of them directly on my PC's USB ports? Will that work at all?

Read the first post of this thread. It explains quite clearly how to set the clock speed to the end of the post.

Also thank you @ the OP. Very nice guide. Looking forward to getting my U2 running.

I am new here to. But from what I have read is that you need a powerd usb hub for this to work off a hub as it consumes a bit more more then a regular hub can provide. I ordered one and should get the usb in today.


Also Can anyone tell me how to underclock this as I want to run it cooler maybe running it at 1.8Ghz would keep it cool.

I'm in something of an odd situation here, I don't know what's going on.

I ran through the instructions and had a successful start-up with my shiny new Antminer U2. But then I had to restart my host computer -- basically the desktop crashed, and then I couldn't open any folders.  So I clean shut down BFGMiner, then dirty shut down the host -- had to, whatever killed the desktop also prevented log out. Now, if I rerun the exact same command, BFGMiner can't find the Antminer, it tells me I have no devices. Device manager sees the Antminer ASIC at COM16, but even using M / + I can't get BFGMiner to see it.

I have tried unplugging and replugging the Antminer from the hub, and the hub from the machine. Note: The Antminer ran successfully before, so I don't think it's a problem with hub power.

Any suggestions?

Edit: Never mind... plugged it directly into the computer and it started mining right away. I guess there's something wrong with the hub...

I get minimal rejects and error rate at 2 gh/s but when I overclock past 2 gh/s i get error and rejects which negate the overclock on bfgminer/minepeon.  This is for both the U1 and U2.  Is this normal? I've been running at 2 for a while now and happy with very small rejects and error.  It would be nice to ramp up to 2.2/2.4/2.6 with under 5% error though.  I have a fan and the heat sinks are cool to the touch.

The A: value is ACCEPTED.  It should continue to increase every time you see the message Accepted xxxxx

The R: next to is is REJECTED, hopefully a low number

Thank you for this guide,

I am looking forward to setting up my antminer

I am new to this and am planning to order the u2 version of this miner. I had a few questions.  I know one is really hard to answer but here goes.
1)How much power per hour do one of these take?
I know it says 2w but does that mean 2 watt per hour?
2)I already have a system running 24/7 due to requirement of place of ownership will the pc it is attached to consume extra power or will it be what the pc is already using?
3)Expected income. I am not looking for profit calculation. I am just asking how much do I expect to make bitcoins wise per month from one of these?
I know this is hard to answer but those of you who are mining with this can give me an idea by taking into account how much you made last month I know it can very but just need an idea?
I live in a third world country and the cost of 1kw/h is only $0.29cents so I do believe if this device only uses 2w/h it can be very profitable here.
Lastly I would like to thank the author of this post who posted such in detail setup of this device.

PS I have read that you can run this with a raspberry pi is there a detailed tutorial on how to set-up a raspberry pi with this?

Thanking you all in advance.

What kind of system setup do you have? I was playing with a couple of these on an 06 Dell XPS M1210 laptop and was getting 1.5 out of one and .7 out of the other. I switched to a Raspberry Pi running a powered Rosewill 10 port hub and am getting a steady 2.0 out of both with the appropriate clock setting. It looks like the onboard usb header on the laptop didn't provide enough juice for both miners to be happy.

Also: Start the miner, grab a cup of coffee, have a coke and a smile, and come back a while later. I've found that the antminers can take a little bit to really find their stride. Hashrates will fluctuate for a while until you find a steady rate. For me working with two miners, I've found that this can take up to 15 minutes. ymmv.

Here is my updated string:

Once launched, I manually changed the S to 30, E to 60 and Q to 15 like your example.  For some reason, it rejected those settings from the command line.

Now, I'm getting around 1.5Gh/s, but I still can't get higher.  If I change from 0781 to 0881, 0981, or 0A81, my Gh/s rate in the third column drops to 0.  Obviously 1.5Gh/s is much better than I was getting, so I'm happier, but I'd love to figure out why I'm still not getting 2.0Gh/s like the U2 is supposed to be capable of.

Also, I noticed in your screenshot that the A: value is always 0 or 1, but mine is A: 34 at the time of this screenshot and climbing every few seconds.  What does this value mean?

Finally, you asked about my USB connections.  Right now, I'm not using any hubs, splitter, cables, etc.  I'm plugging directly into an on-board USB port.

It could be a simple fix, I ran into that issue in the beginning. For me, I find that antminer:all doesn't always pickup one of my Antminer's. I found that using "amu:all" works nice for me.

Before we go further, just for the sake of troubleshooting, run BFGminer with no commands, arguments, etc., and enter your Pool, User, and then PW manually. Next, press "M" and then "+", after that type either "all"; "amu:all"; "antminer:all"; or manually find your AMU's device COM Port and try that way - anyway will work, we just want to run a quick test. After BFGminer recognizes your device and connects to your pool see if your hashrate changes. If it does, we know the issue is simple. If not, try my configuration below.

I run this for solo-mining. For a pool you'll want --no-submit-stale as to keep stale/bad shares off of the pool. On high-hashing Network ASIC's you can get your pool worker banned for an annoying term because of HW (Hardware Errors) and bad shares. The first new argument (or Parameter - I forget what it's technically called) is "-s" This is Scan Time [BFG Readme: --scan-time|-s Upper bound on time spent scanning current work, in seconds (default: 60)]. The next -E is Expiry [--expiry|-E   Upper bound on how many seconds after getting work we consider a share from it stale (w/o longpoll active) (default: 120)]. Finally is -q or Queue [--queue|-Q    Minimum number of work items to have queued (0 - 10) (default: 1)]

I am hoping this fixes everything...

Your HashRates (The one that you need is the lowest)
/5 second exponentially decaying average hash rate/An all time average hash rate/An all time average hash rate based on actual nonces found, adjusted for pool reject and stale rate

Play around with those -s, -q, -E, settings. After you are connected and running, just hit "S" and you can change them live. Just change the -o Pool address and your -u / -p user/pass info before you copy past into a .bat or CMD.

Hope it helps!


EDIT:
I remembered something!
Are you using a USB Port, Extender, Splitter, or HUB?

Mine only can supply enough wattage for five AMU's, this is what happens to the 5th:

http://i58.tinypic.com/10gbcsz.jpg

So for myself, these AMU's on a laptop are 100% worth it and profitable.

I'm really having some trouble understanding what's going on here.  I've been running a single USB Block Erupter with BFGminer for several weeks and have seen ICA 0: with 337/332/355Mh/s.  I just upgraded to an AntMiner U2 and used this guide to configure it, and it seems to be running ok around 2Gh/s, but the third number is always much lower and my pool reports much much lower speeds than even with my USB Block Erupter. 

What am I doing wrong with the AntMiner to get slower speeds?  And what do those three sets of Gh/s values actually mean?


Block Erupter
bfgminer.exe -o stratum+tcp://stratum.btcguild.com:3333 -O xxxx_1 -S all --icarus-options 115200:1:1 --icarus-timing 3.0=100

AntMiner U2

First off, yes, I am a newby, so smack me if I sound way too stupid. I'm running 3 ANTminers at this point, trying to get a "proof of concept" if you will. I just can't get the bat file to work the way You've indicated it should. I've tried setting up the .bat file and if I put everything in it that you've suggested, the command screen pops up and quickly disappears, leaving me with no "visualization". Can't seem to get it to do anything unless I run it directly from a Command prompt window (run as admin), and then it does report the "errors" it's experiencing. It's running on a Windows Vista system with absolutely nothing else on the machine. The reported errors start off with "-S Antminer:all" all is not a number, and then move on to "--set-device antminer:clock=x0781" unrecognized option.

If I delete the "-S Antminer:all" option and the "--set-device antminer:clock=x0781" option, the miner will begin, but does not initially recognize any devices. I can type "M" and then "+" and type in "amu:all", hit "return"  and it will then detect and start up all of my ANTminers. So I am operational, up and running, making money like gangbusters (hehehe yeah right) operating at 1.6GH/s on each, but I can't for the life of me figure out how/or if I could "overclock" them to get a little boost in hash rate. I'd just like to know what I'm doing wrong, and why the bat file isn't working for me, and how I might adjust it so that it doesn't require so much extra interaction/keyboarding to get it running. There are times when I'm at my "real" job and may notice that for some reason, my miners have gone on strike, and would like to be able to call home, have my wife just click the bat file and not have to lead her by the hand to get it back up and running. I'd hate to miss out on that $0.22 lost to the other members of the pool.

This is a great guide. I have been looking for a very easy to use guide.

Thank you

Hi,

Very useful. Hard to find very clear info on what and how to do! So much conflicting data in the world.

Little question if anyone can help.

I have one antminer and two block erupters.
Using BFGminer 3.10.0 with drivers correctly installed.
Have had to manually add each device after starting BFGminer.
Windows 7 64bit.

Can I run all three using the same .bat file?
Can I still overclock the antminer?

Any advice on how to write the .bat would be great . Been slowly pulling hair out for about 8 hours now!
I have read the comments above but im still slightly confused.

Cheers
