ANTMINER U3 Discussion and Support Thread

Interesting. I wonder if it can be implemented on Windows.

or how it can be on Linux ;p

Look through my posts in this thread.

For those of you running on Linux, it appears there may be an easy solution for restarting your U3 without unplugging the USB cable. With the antrouter, Bitmain's cgminer-u3 init.d script stops the udev daemon(linux device manager) when it stops cgminer, and then starts it back up in the cgminer start function, if it is not already running. This allows me to restart cgminer when a unit goes zombie, through the init.d script or UI, and not have to unplug the device. You should be able to port this command to another linux based system and monitor cgminer then restart cgminer/udevd when needed.

On cgminer stop

Code:

start-stop-daemon -K -n udevd -s TERM

On cgminer start

Code:

 ps |grep -v grep|grep udevd  > /dev/null
if [ $? -eq 0 ];then
        echo detect hotpluging USB miners
else
        /sbin/udevd --daemon
        echo start detecting
fi

here it is !

thanks

I had zero freeze/zombie issues and a "set it and forget it" mentality with this config:

RasPi 2 (with freeze watchdog enabled)
MinerA (with auto reboot set when miner stops hashing)

One U3 would be solid hashing then die randomly;  and within 5 min it resets itself and bam.  back hashing.

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.  But this could be due to using windows I was on a windows machine with them just as I had it on.     So not sure how much that effected it.

I went from it to the R1 from crazyguy.

FWIW windows 10 here.

Mine has the LED on even when the PC is in sleep mode.

I can say I did not try it during sleep.  Why would you not have sleep mode off with a computer mining?

I had sleep off as PC was on always. It is actually a PC I mainly use for teamviewer.  But it allows me to use it as a controller if needed as always one.

No, I mean if I manually put it in sleep mode. It's probably because the USB hub still has power on then.

This watchdog ?: http://blog.ricardoarturocabral.com/2013/01/auto-reboot-hung-raspberry-pi-using-on.html

What setting in minera do you use ? Because I tried several, without success...

If i tell the miner to restart after 600sec (10mn), it restarts after 1mn anyway...

i cant quote on the watchdog, but its well documented;  I followed an online tutorial.

Thats the correct setting for minera;  just set a sane timer for reboot (2-15 min?)...

I always saw a solid hashrate bar in the readouts; and can normally see blips in the hashrate graph if it reset....

With MinerA I believe I used bfgminer;  gridseeds the regular cgminer.

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.

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...

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
