Done some more testing her, got hand on another u3 as well, total of 3 now.
1) Did work for a little while pretty well. then stopped functioning at all. Test different psu, cables, powered hubs etc. Cleaned up inside, still dead. Got a refund from Cryptocrane
2) The other one from Cryptocrane worked, but a bit slow. Faster now with the cgminer 4.8 build from Antminer, might be that one optimizes a bit better than i managed myself. Cleaned it up inside as well, no issues with just this alone now, nearly ever zombies. Directly connected to the pc, usb 2 port.
3) the new addition, reportedly unstable and zombie'ing. Cleaned it up inside, applied new paste etc. Working pretty well, but something wrong with usb recognition. I have to install the winusb driver again if i unplug it, even if back to the same port.
If i start cgminer with both connected, it fails. Starting cgminer, adding one, waiting till it runs, then adding the other, and they seem to be stable for quite a while. Not working with both of them on the same hub.
Zadig freezes if it believes driver install failed (even though it actually installs)

It is the right operation

Question:
What is 'invalid nonce -- hw error" ?
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.
Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
Hello,
I have been kind of busy and dropped off here. I got a S3+ it set up like a dream, why cant they do that with this?
I burned up one power supply running as they suggested. Now I have dialed things back to -bmsc-freq 0782 --bmsc-voltage 0750. They will run for about 5 hours and then just quit. Not Zombie, Just not hashing.
I have one powered off a Molex and one with the original power supply, I put a small fan blowing on the Bitmain power supply,
Each runs at about 34 gh, which is a long ways from the Supposed 63.
I know Bitmain monitors this forum, would someone let us know what is going on?

Try multiple pools:
eg. -o xxx -u yyy -o mmm -u nnn with other parameters you set.
with voltage 0750.please set freq 0882 or 1106
And we make a new U3 manual to help set freq and timeout.

Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
Is it possible to power the U3s from a Molex with the correct adapter? I melted, a power supply last night running at bmsc-voltage 0780 --bmsc-freq 1306, which was as high as I could get w/o too many h/w errors
Is Bitman going to replace our burned out power supplies,
Guess that is kind of two questions

for freq 1306, voltage 0780 is lower.set it 0800
Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
currently trying new U3 since last week.
with the latest cgminer fork from bitmain's website it seems to work without zombie now.
But:
is there a way to have an U3 and U1 mining on the same Win7 machine? I know U1 is like a joke, but all this kinda below 1 TH is a game these days.
any way to monitor temp of u3 and adjust the very NOISY FAN?
this here is never ever at 25 db (at 20 celsius room) more like 60-70 db.
Just get the U3 mined as usual,after it worked ,connect U1 to your Win7.Since the setting is not suitable for U1,both of the miners work,but U1`s hashrate is lower as indepdent,with the latest cgminer fork from bitmain's website it seems to work without zombie now.

Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
Try this:
Code:
cgminer.exe --bmsc-options 115200:0.65 -o xxx -u xxx --bmsc-voltage 0800 --bmsc-freq 1306
Using these settings raised my GH/s from 40 to 50 but now I am getting large number of Hardware Errors saying Invalid Nonce. The vast majority of all frequency settings spit out this same error except for 0755 voltage 0782 freq and 0755 voltage and 0882 freq, but I only get 30 and 40 GH/s on these settings.
Also, I haven't been able to get it to run for more than 12 hours without going ZOMBIE or just sitting there hashing at 250 MH/s.
Any ideas before I just get rid of this thing?
EDIT: Lasted for a whole 7 minutes at 50 GH/s, now is ZOMBIE. Going back to the 0755 setting for a whopping 40 GH/s.
try voltage 0800 freq 1286 with --bmsc-options 115200:0.57
about ZOMBIE issue,we have answer in another post #210
Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
This is pathetic! I can't believe Bitmain would release a product with no solid instructions or mining software to support it.
Maybe if we all email bitmain asking for an Rpi image for the U3 that works they would post one (and for anyone not planning to use an Rpi we could always deconstruct it if we know the cg version used).
I have tried everything I could think of using the settings designed for the new chip. I am now going through options settings for the old ones to see if any work (i.e. icarus options with amu setting etc.)
So far no luck with anything.

Re: Antminer U3: Decentralization continued. Order now, Ship on Nov. 5th
Got mine today. Plugged it into my machine which is currently running 2 Ant U2's with CGminer 4.4.2. I used Zadig to install the WinUSB driver for the device.
Do I need to update CGMiner or change my command line to get this to work?
UPDATE: Tried CGMiner 4.7.1 and no improvement.
Icarus detect (1:11) fialed to initialise (incorrect device?)
Is no one using else using their U3 yet?
