First thing is to try it on a mainstream pool like btcguild. |

My B2 S4 works perfectly running 7 x 24 for two weeks, but two days ago the hashing power goes from aprox. 2Ths to 0 without any reason. I'm able to access the miner, that shows the hashing downgrade. Soft re-start makes no difference and I need to manually restart it to get full hashing power again.
Do anyone else have the same issue? Any work around it?
Thanks!
One of my S4 has been doing this for a few days as well lately... any ideas? Can you give me a screenshot of the status page please? |

..... It looks like its a fixed voltage pump with the 4th pin unconnected to the actual harness. The other 3 pins would be +12, -ve and rpm sens.
dogie- You're wrong again. Write the better things that you know. C1 not only regulate pump speed, C1 even shows the speed of the pump. I said I think, no need to be so aggressive. Then, when using the harness, its varying the voltage of everything on it down. But to answer the original question, its not using PWM. |

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. |

Antminer S3 is basically okay. Support from BITMAIN in Europe however is not existent.
I have some bricked controller boards as well, emailed them, some emails back, no result. I would pay for the controller boards, not an issue.
Why do you think that people open threads with bounties to run the hashing boards on a RaspberryPI?
PM BitmainWarranty and they'll sort you out, support is getting so much investment of time and systems at the moment. |

Is the cooling kit necessary?
100%, yes. If you want something similar but without watercooling, pick up an S3 or S5. Great work on the guide! I gave up on the gibberish instructions with the kit. I am noticing a massive amount of "discarded" shares...
Is this normal?
Discards are entirely normal and shouldn't really be displayed at all as they're meaningless in regards to mining performance. Think of it as someone counting how many times you close your front door on the way to work, in a work performance report. Alright, great. Anything on overclocking yet? I did see a field for that but have no idea what voltage to select. Also, where' s the SSH? Also, any guides about the S5? I don't typically include overclocking as it varies unit to unit, voids your warranty and for 95% of users isn't applicable. I haven't seen much OCing data for the C1 but to be honest I don't expect there to be a huge amount of headroom. Hardware wise its not dissimilar to S3s which max out at 480-510, and we're already at 505x2. S5 is soon TM |

I've been having the same problems but for the last month or so. Donate page goes down, wiki stays up.

Hmmm, I have a 1300 SUPERNOVA G2 Running two aintminer S3's My electric service to my house is 120v 50 amp "MAIN BREAKER" My miners are on a 20 amp sub breaker by itself. I really need 100 amp service I Don't think Adequate Power is coming from the wall that's why this happens. I took them to my cousins house he has 100 amp 220v service I can oc them to 524 "262" and they work fine.
power isnt everything.. these miners have a mind of their own.. i highly doubt you are reaching 20 amps.. you can try to wire in an outlet to 220.. i hear people have good success with this. As long as you're a professional, know what you're doing and can do it safely. The last thing you want to do is burn your house down, incur a hefty bill from the power company for repairs or invalidate your home insurance. |

I remember seeing this posted but can't get it to come up in search.
What fans are used in the S4? I have one that went bad and want to order before taking it apart.
Also is anyone using a quieter replacement?
Thanks in advance.
I never found out as they're genericly marked. If you dropped a front fan you can replace it with one of those high performance high static pressure Corsair fans that are easily attainable now, as only the rear fans are important in this layout. Temps literally don't change (I did it on my S4). |

You could plug the pump directly to one of the hashing board headers
Has anyone tried this? Could feedback response time be a problem? Constantly running the pump at a set speed that would be less a problem but slow that fluid down and this could warm up quickly. I suspect I will absolutely need an outdoor pre-cooler once it gets warm this spring. I have a thermostat circuit I use for a DIY egg incubator. Less difficult controlling a 12vdc pump to put water onto an outdoor pre-cooler that will have air passing over it. The system isn't pressurized so the sensor can be mounted in the water outflow of the pre-cooler. I lived in Tuson back in the early 1970's and the place had a cooler on the roof. A large box-like enclosure with the 4 sides having material much like air conditioning filter material. Water would pass down thru the material and in the center air was sucked into the home. It's very dry in Arizona so it worked there without the home becoming too humid. Running water over an outdoor pre-cooler wouldn't raise the humidity of the home here. Georgia is much more humid than Arizona. The first harness did this it was not the greatest. If you make one with higher quality wire and keep wires from touching each other it could work. I would personally go for molex to fan connector. You get a constant speed. With it you don't get a variable speed, but you will always have it being powered when unit is on. Also saves troubles you will see twords first of thread. That cable wouldn't send any PWM signals and I don't believe the pump would accept them anyway. It looks like its a fixed voltage pump with the 4th pin unconnected to the actual harness. The other 3 pins would be +12, -ve and rpm sens. |

Hello
Opentoe, I know one person with the same problem with one C1 bath 1.
We configure the miners with standard voltage 0725, the chips to 256Mhz save and aply. Wait 1 minute for save and apply and turn off the miner 1 minutes. Turn on and wait 10 minutes. In the hash rate is less of 900Gh, we continue turn off, wait 1 minute and turn on again until the hast rate is near or 1Th.
Please, is important wait 1 minutes between turn off and turn on.
Regards.
Antuam.
Really? This is actually a batch 2 unit, but anything to try I guess. The longer it runs, the lower the hashrate. So I'm thinking a buggy firmware with a memory leak that's killing it because when I power cycle it, jumps back up to 1005TH and then slowly starts dropping, real slow. I'll try this "trick" once it gets back down to 900 again. Thanks. Which pool is it on? I don't think its the solution but worth a shot. |

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. |

|

So you've had the same? I'm confused as to why some people would be able to flash the firmware and others not :s Any ideas? Edit: Also reported to engineers |

Yup, Slush's avg ghs is bringing me back down to reality...Its stating 114.5...
But I am noticing a big difference in ghs depending on which version of CGminer i am using...4.5 & 4.6 show the biggest ghs, 4.7 & 4.8 are more or less in-line with what i am getting at the pool...I won't load 4.9 because my virus-scan thinks CGminer is infected and quarantines it - Lol...
Still running the box at -- rock freq 350 - temps around 35c with ambient temps of 16c...was running at 43c with ambient temps of 24c...Did R-Box put out a recommendation on temps?
Dogie - thanks for the advice on multiple R-boxes and putting this post up...
They're BE200s so can run quite a bit hotter without problems, like 50C hotter before you even consider them hot. CGMiner displays may differ because CK may have altered displays or code for certain products in between versions, but the latest version is always going to be the best. |

I've still got some questions that I think went unaddressed - besides the holiday I've been phlegmatic and unconscious for most of this week. Regarding the expected hashrates from a 0.8V chip (22GH according to the first-post chart) and 60 chips per machine, why the machine's hashrate is rated at 14% under that. Also what provisions were made to keep node currents stable during chip use fluctuations. One user keeps asking for the ability to disable individual chips, which for a string miner would be a pretty bad thing to have happen but if chips disable themselves, what provision is there for proper currents to keep flowing? Are there any provisions for chips overvolting? Like say, using a server PSU that's reading high and outputting 13V instead of 12 (which isn't terribly uncommon), giving you an 8% overvolt - say one node in your string fails short and now you're running 14 nodes. You're now 15% overvolted on all chips. How is that handled? I'm not really looking for proprietary trade secrets, I already know how I'd do it if I were making a string miner. I just want to know that some of these safety measures were not overlooked. It's entirely too common for string miners to catch on fire - they're a really good idea, but with a few particular tricky details that shouldn't be left up to chance.
Forwarded again to engineers, I did before but no answer yet. |

  These are not even the same building, yet this is what Michal claims his office to be located. Office pics from his website deleted in 5...4...3... (I'm battin' a 1000 here). To be fair that does very much look like the same building, just the back of it. The numbers would match up as well as they're sequential. The L shape of the building is at the rear corner which is obscured in the first picture. |

http://web.archive.org/web/*/http://emic.com.pl/en/wp-content/themes/emic/images/Hey, Michal! You're doing a lot of work for nothing, i.e., deleting your images, for I'm already archived them and have them saved on my computer. A fact that I've presented to you twice already, but you now feel it prudent to delete, hence more evidence that what you're trying to accomplish is a scam. It must be sad for you to have not only suffered a major bump on the head when you were a lad, but also being Polish. We came here to make it as easy as possible for you to perpetuate your scam, but you just keep on fuckin' up not wanting to succeed.Seriously, look at all the moneys you're leavin' on the table simply by not heeding our advise. Surely, Alex Sovu and Joshua Zipkin aren't smarter than you, are they? It sure the hell looks like it. Fixed your link |

Hi there!
I have some S4 running at BTCGuild (2048 diff) and some at another pool (around 1700 diff, varying). The ones at Guild are all showing zero bestshare, the ones at the other pool are showing actual bestshare values. Hash rate seems good, better actually at BTCGuild than the other pool. Does anyone have an idea what could be the bestshare problem?
Thanks!
It's an Antminer bug. All of them after the S1 don't show best share if the difficulty is a factor of 2, say 512, 1024, 2048, 4096, etc. M Isn't best share just an indicator of how 'close' your random chance got to finding a block? Is there another use for it? |

My miner status webpage "Cgminer or luci" what ever its called is giving me the wrong figure I posted two pics one from the pool site and one from my web GUI you can see what I mean I have to stop/start/restart cgminer or reboot it completely then The web GUI shows is correctly is there a fix for this ?
What is the second picture from, that's not the normal miner interface? |
