ANTMINER U3 Discussion and Support Thread

[jailBot]

Cool. Thanks for the info.

I decided to pop the case open and peek inside and it doesn't look like PWM control is an option. If I had to guess, the miner uses thermostatic control to prevent overheating. The fan header being used is a 3-pin so I think the only way to gain control with the same kind of granularity as PWM would be to build a voltage regulator for it. This would be more work than one miner is worth.

I was looking as both sides but like you said, the long term average is fine. I was just curious about what the behavior is indicative of. I'll try messing around with diff setting.

I dont want to send anything back , unless you think its broken

What does Zombie mean? does it mean its broken and cant be fixed? Is there anything I can do to ensure that it stays mining and not saying ZOMBIE ?

I have an antminer u3
7 port Powered USB HUB, with AC adapter
ZADIG 2.1.1
CGMINER 4.8.0

I actually also had this problem at the beginning. After removing the powered hub between the antminer and my Raspbian, it stopped displaying Zombie in the cgminer

That's a good idea. Going zombie on these is typically due to some form of interruption, the most common being power / USB power related.

Mine goes ZOMBIE about once per day. Sometimes twice in one day, sometimes it runs for 2 days straight. Is it a defective unit or not? I use CGminer 4.9.0 with no options. Plugged directly into a USB port on my desktop PC.

No. Good old 2.0. No one ever said USB 3.0. was a requirement.

There are lots of small, annoying things which can make it go zombie as there only has to be a very brief interruption for it to kick out. It might be you're using USB 3.0, or using it via a powered USB hub, or not using it via a powered USB hub, or the power supply overheats / flickers. Or, the product itself could be flickering to the point that its 'faulty'. Either way, you're free to return the product for replacement to our US base.

Thanks. As a point of reference, the Ant U2's in the same type of USB ports NEVER go Zombie. The only difference is that they don't have a power supply.
I will return it, but I believe I need an RMA #, right? I'll send it to the CO location.

Yes, I will have someone PM you to arrange the return.

Disabled antivirus downloaded bitmain cgminer and tried again, still same problem.

Yes, cgminer shutdowns as soon as the 2nd freq shows up, i never get to the actual mining thingy.

Are you starting it by cgminer.exe or a .bat file? If its a .bat file, add stop to the end so it will pause and give you the error screen before it closes.

[Iskavan001]

cgminer.exe --bmsc-options 115200:0.65   -o stratum.btcguild.com:3333 -u Iskavan_Icarus -p 123  --bmsc-voltage 0800 --bmsc-freq 1306
stop

and i tried echo stop, and stop directly at the end of this, still closes i manages to take a screenshot real quick and it just said stop was unrecognizable or something like that.

My bad, "pause". It will tell us which bit of the .bat is wrong.

I added pause, this is what i got. if i press enter it closes.

Its doing what its meant to be doing, I still suspect its some form of antivirus or windows defender which is closing it as its shutting down at a point that cgminer never would do so itself.

But, i can mine with my graphics card, at 500mhs. I just allowed cgminer through my firefall though just to make sure, still the same. all went into task and turned off all antivirus.

It has to be something silly im missing.

So i downloaded cgminer 3.8, ive been trying every version now. and i got this . . . when i plugged it into usb 3.0 slot, usb 2.0 it does the usually.
What does this latest event mean?

But you're not mining on your graphics card with this particular instance of cgminer. Maybe CK will have some ideas as to what's going on once he's back.

Are you using a USB hub? Is it powered? USB 2, 3 etc?

Probably a hardware issue, most likely vreg bugging out.
