If you want variable you could buy a fan controller to hook to them. But Dogie is correct about all the watercooling in most cases being constant.
That's a good idea, if you want to add some control you could wack the pump and others through a fan controller (making sure it can take the W per channel of a pump first!). Although, why exactly do you want to lower the pump, its probably saving you power by running at max rpm and keeping board temps cooler. |

What happened to the 25 EMIC Miner V1 miners that somebody tried to order on September 21, 2014? Must have been special otherwise you wouldn't have taken the sceenshot back then.
Link seems dead, no? Your linking of the link looks good, so maybe rehost it if you've still got access. |

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. |

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. [...]

is not the USB port version 3.0 [blue color inside]? 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. |

What do each of these images mean? Does this mean we're getting a +1 and a 'favourite' feature?
They are just some icons bundled in the current new forum software development, they might be used or they might not, but the fact that they have created them shows that most of that icons will be used. I need my beloved thumbs up  Or a little dog symbol |

I would think even with connecting a copper radiator to an aluminum heatsink if one used distilled water it would be okay for a while. As the water accepted ions it would start to become conductive.
Even distilled water / distilled water mixes are going to contribute to the problem after a while. I personally would stick to a premix / non water base. Ethylene Glycol has a heat carrying capacity only half of pure water. It's also used as a desiccant (from the Wiki). We aren't talking about sufficient heat to vaporize water in the miner heatsink so perhaps the Ethylene Glycol alone will be good enough. Reduced heat carrying capacity would mean that some ASICs will be running hotter at the output. Not having a C1 yet I wonder if the pump speed varies or simply runs continually. I've read some posts about running the cooler fans from an unused fan connector on a C1 hashing board. Pure water would carry the most heat away so if the pump runs constantly at a set volume per minute and if the fans are made to run relative to the mid-hashing board heat sensor, pure water means less fan usage, better hash rates, generally lower temps if the pump runs constantly. Listening to my two S3+'s and two S3's in an unheated room with windows open, it gets very quiet at sub-65°F. My pump at least is constant RPM and doesn't vary. The C1's fan does vary with chip temps, but is very conservative until things really start to heat up. So do the fans on the cooler have a controller board that vary those fan rates? The only variable fan is the C1's fan, which plugs in directly to one of the PCBs and is software controlled. |

I'm not going to discuss this any longer in this thread as its off topic. If you want to have a conversation about it, find a more appropriate venue for it and let me please. |

From BitmainWarranty: "C1 uses a similar looking PCB to S3 or S3+ hashing PCB, but it is little different, so Please DO NOT mix them as the connector even facing differently."
So the C1 boards are NOT S3 boards just a bit clocked up correct? Just for clarification please.
In terms of hashing power they are. Wow now I do see what others are saying is true. When I first started reading your review threads over a year ago I really got behind what you were providing to the community, they were both very helpful to most, and an enjoyment to read. I am not sure what happened but maybe you have spread yourself a little thin. Your justification for the inaccurate answer you provided to the original question is childish at best I am sad to say. Please try to get back on point Doge. Sorry, half my post is missing there (was on a phone). He is right, the PCB is not identical as there are some modifications to aid the use of waterblocks. |

I got a U3 for Christmas and after tinkering for a few hours under the tree yesterday, it's happily hashing at ~56GH/s. I settled on an RPi running the cgminer build from the most recent Minera img. I let it run overnight and there doesn't seem to be any major issues. However, there are a few specific questions I have that I wasn't able to dig up answers for.
1. Has anyone come up with some general thresholds (safety/stability) for the voltage and frequency settings? I'm messing around with the stock equipment until I can integrate into my mining rig back at school.
2. Is there any way to forces PWM values to the fan controller? The fan runs at a sluggish RPM and I'm past the point of letting miner fans bother me. I'd prefer to crank it up and cool things down.
3. What causes the fluctuation of the hash rate? Over a 15 minute period, it'll bounce around the 35-70GH/s range. I see the same thing with my big rig, but I've never looking into the cause.
Thanks!
1) Anything higher than 800, even 800, is considered high regarding voltage. 2) Not that I know of 3) Are you reading the hash rate miner or side or pool side? If its miner side I wouldn't be too fussed, even pool side as long as the longer term average is good. Setting a lower difficulty would even out some of the random effects. |

With the class action against AMT being official, just curious if AMT ever actually went ahead to sue IMET or it was otherwise settled? Any info here?
They probably filed an initial complaint then ran out of money to continue. |

Is it all of your S3s that have the same problem? What do the status pages look like when they stop mining? Are the units on DHCP or static? What firmware are you on? If its a firmware after 1024, you will want to revert back to 1024 or the beta firmware below. Can I get some beta testers for a new S3 firmware please? Download link is here, it *should* be good to go but as you know.... Rolls back to the last good patch in Oct (1024), but fixes voltage adjustment and the important reset button. Hopefully.... let me know. MD5: 7DF1B12D28B25E10AAC37E2EAFC7397B Ps in the future, please try and find support in the S3 thread rather than making a new one. they are all static and yes it is happening to any of the 14 at totally random Before you resort to buying more hardware you can try DHCP'ing at least a few of them to see if they stay up. DHCP usually sorts a few problems out, and you can stick devices on to always retain the same IP. |

Please enjoy MOQ 1 while supply last!!! Did they get rid of the purchasing 2 requirement?
You nearly had me there. Had my finger over the buy button but just couldn't do it with the shipping as well. I'd really really like an S5 but just at the current cost/difficulty level plus what I pay for electricity I just can't bring myself to do it. Coupons may sweeten the offer though  But really, thank you for listening to your customers. I know there's a lot of whinging and complaining here about certain things but as a whole I've had a good experience with you guys (Tim, your support guy especially)  That's why the MOQ was there in the first place, as its represents better value to the consumer. No one (including Bitmain) likes paying delivery charges for a single miner. |

The problem here is Dogie claims to remain indifferent in how it claims to rate each company. No individual can remain completely unbiased when you are employed by one of them. If you go through many of his posts in other forums, they are usually one liners auto scripted, at times taken out of context. In bitmain forums, he rarely helps anyone to completion. Rather he hands off the problem to bitmain directly, wasting everyone's time.
The final straw, he has insulted way too many people here. No company with any logic would hire him with his lack of community.
Pat, we all know what you're doing - you need to make some more accounts if you want to keep flaming from secret. Dogie, please confirm that the highlighted text is a typo, that you actually meant pak as in pak13 the author of the text, and that you were in no way referring to me. Again. Just to be ensure there is no confusion. No I mean Pat, or workinginconcertwithPat. This entire string is off topic though so please take it elsewhere. |
