ANTMINER U3 Discussion and Support Thread

[-ck]

Thank you for the PSU warning. I have another 12v source i am using. Could you please give example .bat file or config file people can follow. I would really like to try out the 4.8.0.

I am using this and getting about 55 GH/miner cgminer.exe -o stratum+tcp://(pool) -u (username) -p (password) . I would like to know how to change voltage and frequency, if anybody would post it here, I would greatly appreciate it.

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

Code:

--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)

WOW Works like a charm. It is much better than the bitmain's cgminer. You can run multiple U3's right from the start. GREAT JOB, I love my U3's even more now. Thank You. only thing is that sometimes pool starts with too high difficulty (1024) and just have to restart cgminer couple of times and it jumps down to (16)

I should hope it works better, that's why I keep complaining when manufacturers don't involve the guy who wrote the software

If you're on a good pool that supports suggesting a diff (hint, only kano's ckpool and my solo ckpool) then you can also add --suggest-diff 42, or whatever diff you'd like it to start at, as a hint to the pool. Ideal is probably about 40 diff per U3.

Why should they involve you when you fix all their problems for free .

I'm sure they will start to include you once they include the guys building/buying their PSU's into the design process, cause running a PSU at 100% is fine, right?

Where is the binary for the 4.80 version. I have 4.71 running default. Seems to work ok cept that my miner runs really hot. I tried the included power supply which is less then a piece of crap and it barely worked. Pitched it in the garbage and hooked it up to one of my main line power supplys and it works better except for the fact that it won't hash any higher then 45gh. It bounces all over the place between 31 and 45gh and the bottom is quite hot to the touch. Hot enough that I really don't want to hold it more then about 5 sec's. Any help I would be great full for.

Where the official cgminer binary always is.

Thanks for the update CK. I tried it and it works great with my Ant U2's. However, running at default settings I started at midnight went to bed and by 8am it went Zombie. I reset the U3 (USB unplug & replug) and it has been running over 24h at about 54Gh.

I'm still pissed that I've had the device for 3 weeks before it was really usable. This could have been completely avoided.

Hi,

I'm building from git on a raspberry pi, what should i use for
./configure --              # then? 

Thx,
with the windows binary you prevented me from sending back my u3 

[spazzdla]

Seems the best idea would of been for them to make a single card S3..

Big Thanks,
but one Question: How can i configure the miner to Run in a "normal" Window and not in "cpuminer-style"

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

Agreed 100%.  I LLLLOVE my S1 and S3.

If they make an S5 that is like the S1 and S3, I will buy a couple.

I've made the first official cgminer release with support for these now (version 4.8.0). It is the same as the last binary I updated in performance but has some cosmetic improvements.

Note that these PSUs are VERY easy to destroy and I highly recommend people do not overvolt them with the provided PSU. Damaging the PSU will likely destroy the U3 as well. I'm not really sure where the fault lies but I suspect the PSUs are dodgy and if you have another power source, use that instead until bitmain can confirm whether there is an issue with the PSU. It wouldn't be the first device they've sold with a dodgy PSU.

I can only seem to get either my U3 or new R-box running at a time, and have Zadig'ed many a time. Is there no way to get these running together? I've tried multiple USB hubs, powered and unpowered.

Try putting just the U3 behind a hub and the r-box on a completely separate USB port(the hub should filter out interference or whatever is causing problems with the r-box).

In your own words

Engineering > all.

The designers of both of these devices gave them identical (crap cheap) usb communication chips and have set no identity for manufacturer or product so now about a dozen different devices look identical on the bus. The best cgminer can do is poke it with a stick a few times till it goes ouch in different ways to say "hmm, looks like a frog" and then gives it the rockminer driver. This reliability of this is variable and works in my testing on linux. Perhaps it might work better if you start cgminer with one connected and plug the other one in after since hotplug works slightly differently. Sometimes they dont like to let go of the same USB bus ID so need cold power cycling. I can no longer do any more testing since bitmain sent me 2 U3s and it appears I've fried both of them (hence my warnings earlier on).

This time I made it about 2 days before it went Zombie...

Right, I call hardware instability. Both of my U3s are now dead, as in completely dead unusable.

And as a side note. I bought my unit at MinerSource and I left a review for this item there. I thought I wrote an objective review where I detailed all of the problems I had with the unit, along with compliments for the packaging. It's now clear that MinerSource has no intent or interest in publishing honest reviews, which is disappointing.
