What is the command to start cgminer in lower difficulty. Bitmains user guide suggests --diffstart 6. Cgminer just starts and closes when i have that in command line. Is there different command i can use?

I've been running two units, they never stay online longer than 24 hours, unplug USB and replug and they start mining again. Today I happened to be near when I heard one of the units making a weird noise, from the console I could see it had just stopped mining. The sound is like a hissing capacitor discharge, the red LED kept flickering, and the fan was going on and off.
I unplugged the power and USB, replugged both, and mining resumed.
My bet is on the PSU crapping out. I am running the standard values per the PDF doc.
I ordered a replacement higher capacity PSU.
Anybody else notice the hissing when mining stops?
P.

The more I read here, the more it becomes evident that Engineering has been over-ruled in favour of Marketing, Sales and artistic design.

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 ).

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. --au3-freq <arg> Set AntminerU3 frequency in MHz, range 100-250 (default: 225.0) --au3-volt <arg> 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.exeOf course this is all new code but so far it's looking stable, but I'm unable to test the windows binary myself.

I used the official CGMiner 4.7.1 package, and just replaced the EXE file.

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.

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 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.

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?

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

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

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.

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

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.
