Got somebody better settings for the U2? I know i can put it up to0A81 for 2.2 but i think for that my usb hub is to weak. tryed it and my errors went from 13% to 70
That is a U1 config i found i just put the clock rate from 0781 to 0981 (2GHs)

I should have mine in a couple of days.  I'll see how far I can push it with a USB3.0 hub (more power than USB2.0 hubs).

I'll test it right now. I just got a new hub that should power it enough for 0A81...I hope :/

What's the verdict?  Will it hit 2.2 or 2.4?

I can't get a stable hash 0A81...I'm not sure if it's my Hub or what; I'm still trying. I can get it to pulse 2.5 then it drops off. I'm going to compile CGminer 4.2 for win later today and try that. I've been on the most recent BFGminer.

AMU0 = U1
AMU1 = U2

Using:

Code:

bfgminer.exe -S antminer:all -o A_BTC_Pool:3333 -u User -p d=16 --set-device antminer:clock=x0981 --icarus-options 115200:2:2

0A81 drops off lower than these settings... :/

   I don't think BFGMiner recognizes the Icarus values any longer. It just ignores it. Once you get up to 4 AMU's running together BFG will run for a few minutes then bumps up the minimum diff to 4 and after about 20 minutes it will automatically increase the que also.

[Proteu5]

Yea, I've been noticing that with the Queue. The new CGminer requires you to recompile with --enable-" " strings. I'll try it later; I'm hoping to see something nice.

I run with my settings (see abouve pic. 2 GH/s even (2.08239). If i use 0A81 I get a 70% Error rate...USB hub to weak?

Maybe.  I know that on the U1s, if you tried it without doing a voltage mod, you'd get something similar.  It's quite possibly the same thing.

If its a lot of Hardware Errors then probably need better power to the hub, if you have a good adapter check the cable to the computer.

Just got mine today.  I was able to get them up to 2.4 with 0% hardware errors after almost 2 hours of runtime. 
They do take up two slots each on my Anker 13-port hubs, limiting me to 6 per hub (without cables).

Nice would you like to share your config file. cuz mine is not running to stable anymore. would be awesome. Run my U2 on CGMiner 4.2.3 on a Raspberry pi

Here it is after 8-10 hours:


I'm using MultiMiner with the BFGminer 4.0 beta.

Code:

-S antminer:all --set-device antminer:clock=x0B81 --icarus-options 115200:1:1 --icarus-timing long=90

My results

Hmm ok I am not a expert here and I just start playing with bitcoin stuff. As I mentioned before I use a Raspberry Pi with CGMiner Ver. 4.2.3 and one U2. So honsestly I dont have any idea what all the settings do. What I know is that I went thru alot of forums to find a answer;)

I know the numbers GH/s is high but the pool stats show only 1.3gh/s . Everybody in the web is just copies from forum to forum the same old stuff. Can somebody be so kind and explain their own settings if poss. using cgminer. The unit is cooled by a 120mm Tower fan i  riped out of a old tower, cut the cable and soldered it to a micro-USB charger cable.So the unit is pretty cool.

You are using icarus options inappropriately and telling cgminer to report double the hashrate. Don't use icarus options at all, they're totally not required with current cgminer and most people use them wrongly as you have.

That's correct.  Setting it to 2:2 causes it to display results 2x higher than actual.  1:1 is the correct setting.  It looks like you are getting a lot of hardware errors which is causing the low reported speed.  How are you powering the Antminer?

Ok so do I just delete the entire icarus-options line outof the config or do I have to thange the value to something else

Delete icarus options and icarus timing entirely.

[jomant]

Ok done. Is there anything else you would change to optimize the performance (add or remove)
BTW I make sure to post I to adafruit other forums and blogs as a sign of being greatful. I know you guys have to deal with alot of noobs/Beginners. After I posted in your offical CGMiner forum i saw that some people got upsaid so I was reading thru the entire readme and found the change with the clock settings;)
ohh here how it looks now.
