Okay finally found some more love for the driver on these now that mine has arrived. I'm having all sorts of hardware difficulties when mixing and matching these with other devices and many hubs so I'm not surprised others are as well.

Anyway I've managed to squeeze some more hashrate out of them. I'm not imagining there's much left in them since this is close to the alleged spec (hopefully without fires or melting...)

At volt 800 and freq 250:

Code:

 0: AU3 0       :                         | 65.66G / 63.67Gh/s WU:889.3/m

As previously, grab latest cgminer git master or the latest windows binary 24-Nov-2014 16:35 here:
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

Thanks ckolivas, current build is working great, getting about 55-56 GH from each miner. I am able to run 3 U3s without CGMiner crashing, running them off of a PSU with PCIe to barrel plug adapters.

Question:
What is 'invalid nonce -- hw error" ?

"hw error" is short for hardware error,most caused by a lower voltage with respect to the freq you set.

It looks like for Windows 7 that the names of some .dll files are wrong somewhere using old links or references.

I fixed the no libcurl-4.dll error just by copying libcurl and renaming the copy libcurl-4.dll
this allowed the new cgminer test build to run in windows 7 x64.
Now on to test the miner

I just had another power supply melt, It is not worth it to keep trying to get these things running. I don't want to burn the house down. Bitmain needs to say something official about this.

I am also on Win8.1 x64, and replacing the EXE in the 4.7.1 folder works fine for me?

Again thanks for working on this CKolivas.

In addition, I have a test windows binary:
http[Suspicious link removed]

In windows trying to run this file returns an error message that
Libbcurl-4.dll is missing

I am on windows 8.1 and having the same problem, missing libbcurl missing, it is in the same file folder

Barbara

I am running it with Win7. Try saving the file directly into the CGMiner 4.7.1 folder and replace the .exe file. I saved it on the desktop at first then copied it to the folder, and it was giving me .dll missing message. I can still only run 2 U3s in one CGMiner instance.

Tried that. Replaced .exe in cgminer 4.7 folder, still got libcurl-4.dll missing message.

Just saw CK uploaded a new binary, will try same variations with this one. (Running windows 7)

OK, just woke up this morning and my AntminerU3 was dead and so was the power brick. Turning it over, looks like the power brick melted. I was running this thing underclocked at 0755 and it still melted. What now?

Sorry this displayed hashrate is wrong. It overestimates it, so I've reuploaded a correct one which unfortunately shows the truth is nowhere near that good. But it is what it is. I'll keep investigating to see if there's any more juice in it, but the unit I'm trying doesn't like higher voltages nor frequencies much.

Okay here goes. Even though I don't have the U3 yet, bitmainUSA let me work on one remotely in the interim so I've merged my own U3 driver into the main cgminer git master and it is now available for testing.

Note the following changes:
You do not need to specify ANY command line parameters to run the U3 (no weird options, timeouts or frequency or voltage required) for it to run at default voltage and frequency.
The default frequency is set to 225Mhz
The default voltage is set to 750mV

In addition, the following parameters are recognised, though the defaults are obviously safest.

Code:

--au3-freq     Set AntminerU3 frequency in MHz, range 100-250 (default: 225.0)
--au3-volt     Set AntminerU3 voltage in mv, range 725-850, 0 to not set (default: 750)

In addition, I have a test windows binary:
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

Of course this is all new code but so far it's looking stable, but I'm unable to test the windows binary myself.

I changed my Windows USB setting per the instructions and I still can't get mine to run more than 10 minutes or so, it goes ZOMBIE. I'm not sure which settings to use, there have been so many thrown around this forum. Really disgusted with this experience.

Try using a powered USB hub, it took care of my zombie problem. I was able to run it on ghash.io, bitsolo and peercoin.ecoining for over 24 hours now. As an experiment, I hot plugged a second U3, and they have been running for over 6 hours at PPC pool. Adding a 3rd or 4th crashes CGMiner. But I am not getting anywhere near the advertised rate, only getting 45-50 GH each (using this setting cgminer.exe --bmsc-options 115200:0.57 -o xxx -u xxx --bmsc-voltage 0755 --bmsc-freq 0782
).
