Bitcoin / Mining support / Re: Antminer U3 problem >90% error

on: April 23, 2015, 12:01:29 PM

Quote from: Amph on April 20, 2015, 02:57:42 PM first thing are you using the correct miner cgminer 4.9.0? command line should be like this cgminer.exe -o http://127.0.0.1:8332 -u fred -p password --au3-freq 225 --au3-volt 800 --btc-address <address> I'm using the last cgminer with minera. I don't really know where to check those command lines, I'm not really familiar with console commands and Pi stuff, just getting started here I'm not using a USB hub, my U3 is directly plugged into the Pi. Is it a problem? Not enough amps?

Quote from: Amph on April 20, 2015, 09:04:30 AM it can be for multiple things, like the software for mining, the usb as you said the pc/raspberry you are using, or defective unit check first your command line(bat file or desktop shortcut), maybe it's not mining correctly proceed with exclusion, it's the best method to find the problems Ok, but what am I looking for? As I said I'm very new to all this and it is a bit confusing. I thought it would be easier

Bitcoin / Mining support / Antminer U3 problem >90% error

on: April 20, 2015, 07:54:09 AM

Hi I finally managed to get my Antminer U3 working (I was trying to mine Scrypt based currency with it - silly me) I got a Pi with Minera and my own USB cord. I get >90% error rate and don't understand why. Is it from the power supply? From the USB cord? What can affect error/rejected rate?

Hi I'm trying to make my U3 to work but it just won't. I'm using a Pi with Minera I changed the USB cable I'm using a solid 12v power supply I just don't know what I'm doing wrong, but it doesn't work. I'm a noob with all this and don't understand it at all.

I chose cgminer. I'm a bit confused with the settings... What is Append JSON conf (-c /var/www/minera/conf/miner_conf.json)? How should I set the other on/off buttons? (Script, auto login, auto-debug...) My miner seems to be recognized, but I can't get a hash rate And what exactly are error/rejected rates? Thanks a lot for your answers!

Ok I installed the latest Minera version, accessed it from my computer. It's very nice btw. How do I make my U3 to start mining? Just plugging it ? No need to configure it, no need for drivers? I'm very new new to all this and I must admit I'm a bit confused.

Hi I'm an absolute beginner with mining and Bitcoins. I had a Raspberry Pi lying around and thought I could use it to mine, so I bought an Antminer U3, and now I'm clueless on how to use the damn thing. I made all updates on my RaspPi but I dont know which version of cgminer to use, how to install it or how to configure my Antminer. Anyone know a good tutorial? Anyone can help me? I feel quite lost.
