Title: Problems of U3 Post by: Chris301197 on July 12, 2015, 11:59:57 PM Hi at everyone! I still have some problems with my U3: hash rate low, difficulty very low (8) and too errors (no valid hash rate for over 2 seconds and blocks rejected) Can you show me a good configuration on Mhz and mV? I modify that on the cgminer.cfg file and work very well.
Title: Re: Problems of U3 Post by: DavieT1337 on July 13, 2015, 01:50:59 AM I made my steps with the Anminter u3+ and got stuck on the default settings.
I got Problems with the Hashrate and god also some Hardwareerrors showin up. After tryin different configs i figured this out for myself to be the best for the Antminer. cgminer.exe --bmsc-options 115200:0.54 -o stratum+tcp://stratum.bitcoin.cz:3333 -u DavieT.1337 -p x --bmsc-voltage 0830 --bmsc-freq 0982 I used zadig to convert the drivers for the USB. Otherwise Mining on my laptop where difficult with an Antminer u3. I used a config and get 72 gh/s instead of 62gh/s. So you can also try: cgminer.exe --bmsc-options 115200:0.5 -o stratum+tcp://stratum.bitcoin.cz:3333 -u DavieT.1337 -p x --bmsc-freq 0B82 --bmsc-voltage 0800 hope i could help ;) have phun regards DavieT1337 Title: Re: Problems of U3 Post by: Chris301197 on July 13, 2015, 01:18:58 PM Sorry, but this script doesn't work. I've tried but the cgminer open the cmd and close it. Can you show me an other solution, please?

Can you show me an other solution, please? Could u please quote ure config, so I can see whats the Problem - Otherwise only 1 of ure Miners should be connected while startin the .bat File. After gettin Hashes from ure first Device. Start connecting the others, if u got more. regards DavieT1337 Title: Re: Problems of U3 Post by: witch on July 13, 2015, 06:59:38 PM Did U try the setting with Pause @ the end like I said in your other post?
Title: Re: Problems of U3 Post by: Chris301197 on July 13, 2015, 10:30:02 PM Sorry at everyone! I've connected the U3 at my pc gaming and the hash rate was 62Ghash/s and very stable for all time! The problem was the notebook that went very slow because it has got only 2 Gb of RAM and a dual-core processor. But the current is more than 800 watt!!! So I'll try to build a new computer quad-core with 4-8 Gb of RAM, a power supply of 300 watt max and to connect more antminers U3 with a very big USB hub. This may is the best solution but only during the day because I've the solar panels and I can save much current. ;)

In case u want to ride the antminers in a Hub. U should inform urself how much u can put on one hub/computer. I got 4x Antminer u3 on my normal Gaming pc and it works quit well. It`s normal there are drops while using the Computer, but it`s not much. Every Miner uses 60 Watt and the Machine runs on a 350W. So it`s quit more phun than the ROI ;D :D regards DavieT1337 Title: Re: Problems of U3 Post by: witch on July 13, 2015, 10:42:10 PM Np, and have a Blast man! ::)
