I thought something odd was up.
I think it was power supply, I resoldered switch line, checked for shorts across pos and neg (hp server PSU) and seemed to have a short. Nothing visual.
I've done this 3 times now and last time seems to have done it.
I think PSU was flicking on and off randomly.
One thing couldn't reset to factory using button, tried all the combos??
Hash rate showing pool side, still can't see GUI though, could be a DNS cache issue now my end.
Thanks for the help any ways.
What would be the recommended min diff for the pool for these?
Any one tried overclocking yet?
I think its hard to say what is wrong without narrowing it down. If you have a different PSU I would try it and see what happens. If you can eliminate PSU problems I would try flashing micro sd card. It seems that a few had had problems with corrupt SD's. I uploaded a good copy that Dogie has in second post. |

For this amount you are better off buying BTC or LTC.
You will be buying a out of date miner, and will never get it back on money. It would take quite a bit more for a current gen miner.

(Hell i was running BFL 5gh & 11 x 10.7 blades up until my last electricity bill - i tell u what it was hard to turn off 130gh that i had paid so much for that was now costing me too much to run)  It hurts but you have to cut the cord on those. For me it was around 8500 watts of GPU that I hated unplugging. But if I don't make money I'm willing to pull the plug. Right now you need low cost electricity and miner cannot be anything near as old as the blades to profit. |

The expensive / hard bit is getting waterblocks made that will fit miners, and then getting new ones every 3-6 months as you change your miners. You're probably better off with some form of ducting and moving air about.
I would agree it would be very hard to keep up on doing this. New miners come out too quick to do this each new generation. You mention a pool.... I cannot imagine how many Bitcoin miners it would take for a pool. It seems like you would spend a small fortune just on electricity for heating a pool with miners. |

Dear Sirs! I’m a new in crypto currency. The case is that I have an Idea for business activity and its related to Bitkoin. [/quot, "Bitkoin " LOL  That is not only misspelled word. That is part of reason I thought decent chance of troll. Second post of his was much better, just still no idea why he got denied. Lacks details. What country, what is causing a deny, etc |

You can spend a ton on cabinets... immersion... i think in end you will figure out most use lots and lots of air. They extract the heat with massive amount of air.
I hope i'm wrong and you make a huge amount, I always wish business with bitcoins luck. But in this case i think you will find eventually most use air (fans, cooling, etc) and will not spend the money for the cabinets with cooling in them or immersion.

It was a while ago but they did have a few block erupters on a raspberry pi. I'm not sure if they ROI'ed on them or not. Personlly i ran all of them on windows as I was using a lot more then the 5 or so they had with it.

This project is proven to been feel interesting. Yes, right now my cabinet is 3.5kw capacity. The question is how capacity should I upgrade my design. Talking from point that I have pictures shown as working production for another application already. So I like to find a spot in bitcoin mining. But the one I have does not fit the capacity requirements yet.
Thank you for your advice mate
I am racking my brain to understand what situation someone would ever use a 20kW contained-cooling rack. Usually these are used with 1-2kW of gear as a sound-dampening enclosure, not meant to actually cool a large amount of power. OPTION 1: You put 20kW of equipment in an open rack or on shelving. It costs <$400. 20kW of heat is blown out the back of the cabinet. OPTION 2: You put 20kW of equipment into a sealed enclosure with a 1.3 PUE AC built in. It costs >$5000 and weighs >300lbs when empty. 26kW of heat is blown out the back of the cabinet. oh, and option 2 is a little quieter, you only have the noise of a 20kW-capable air conditioner. Seriously - this is a product with no market. Liquid Immersion cooling tanks are the obvious alternative, and are quieter, FAR more power efficient, and can move the heat outside of a building by pumping the hot liquid to a radiator located on the roof. It might allow a data center without the airflow to host a few miners. But cost I don't see this as feasible. The true data centers for bitcoin have massive airflow. And they would never need this. I would have to agree to expensive to hobby miners, and no market for these in a true bitcoin data center. |

I have 4 RM-1000's never had a problem. Most quiet PSU ive ever had. |

I'm not sure if your trolling......
But register a business and have all credentials and I am willing to bet you can open a bank account. Unless you are selling miners, or something bringing in income from others I don't see the advantage. A personal account has a lot of protection. It's only if your wanting like a LLC i could understand other account.

I recommend block erupters. BEST value in SHA256 MH/S.
Are you in 2013? USB ASICs are not even profitable right now, they can't even breakeven with the skyrocketing difficulty. It is only a collector item now, you won't be able to earn with a USB ASIC. Pretty sure he meant these: https://bitcointalk.org/index.php?topic=791827.0Or... at least I hope he did. Otherwise, either a) he's a complete tool... err... troll or b) it was sarcasm. I think it was sarcasm. Block erupters are the usb sticks. No matter what miner you look at do some ROI math. |

When the difficulty hits 50B at current tech & current avg watts, big players will start thinking about calling a world-wide truce. Hashrate will top out somewhere after 400PH and well before 700PH unless someone invents a quantum miner.....
Next gen ASIC is claimed to be 0.2w/GHs (SP). 700PH is entirely possible. To to mention i know some mega miners are expanding with 3 cents per KWh contract. They will keep expanding to get a bigger pie. Only idiots like OP keep using "bitcoin calculator" with wrong variable. yeah thats right and when btc drops to 200 usd they go fully red and belly up. I never said they won't expand I just say they will expand very slowly. The 10 % you see is the exception under 5 or 6 will be more common. Sadly i think home miners will hurt worse then most big mining operations. I have winter that will help. Decent priced electric, with quite a bit open to expand still. I agree it was unusual, but the previous 2 were very low. I think we will find a common ground between theGue 2's and 10's. What that is depends on how many operation go online. Guess we will find out in a week or so and have a good idea. When the price declines far enough, the big mining operations will be the first to slow down/stop their expansion. I would say that at-home miners likely have higher electric costs then the big mining farms, however they also are less aware of the breakeven price that bitcoin needs to trade at in order for it to be worth it for them to continue to mine. As a result, the corporate miners will likely start to take their miners offline (and attempt to liquidate) their miners as the price of bitcoin approaches their breakeven point Dumbest shit i've heard You talk like the difference in electrical rate is marginal. Home miners pay avg at $.10/KWh Mega farms pay avg at $.5/kKWh. Good luck with your wishing noob yes but they pay to set the gear up wire the place cool the place. coins dropped from 1150 to 310 even lower 289 a few weeks ago. we all know they (data centers) have a big edge. but 300-330 usd a coin is close to an edge/cliff for them that I don't face if I double my capacity. If I go from 6 to 12 s-3's my cost for setup is $0 above my price for the s-3's if a big farm goes from 1 to 2 ph yeah they get a good price on the s-3 better then me but they have to do setup and 1ph in s-3's = 2000 s-3's or 700 asic miner long tubes . I have psu's paid for on hand they don't. All easy for them to do these outlays when coins are 500 usd at 320 usd not easy. the coins drop to 200 from 320 and they die. me I am out 6 x 200 = 1200 bucks. oh big farms don't pay .5 a kwatt they pay .04-.06 a kwatt. but that is just the power not the wires the psu's the rent the cooling the salaries. So I know where you are coining from. it is hard for the little guy to compete. BTW you are amazing when it comes to the insults and rudeness you display from thread to thread. Have to hand it to you. I'm in same boat as you. I can expand with current electrical. Even have a building or two left.... I finnaly ran out of my stash of PSU's so I would have to buy those. And it' winter so I can use air outside for free / super cheap cooling. And cameras and security is already set up. Miner cost for them is at a discount (most companies at least). They save on shipping as they go by pallet. Some even can drive truck loads from manufacture to data center (look at china). Each has it's pros and cons. I think the big data center has biggest advantage (and they have huge capital in most cases). I do not think home mining is dead though. For the lucky its alive. Now those who pay vat and huge electricity I would agree they are dead, unless hosting somewhere. |

I dont know about mining speed required and things, can anyone tell me that how much Bitcoins i can earn per hour from that speed? You can search on the web: http://www.bitcoin.org. It is so ok for your question.thanks From 2 video cards very small. Also do ROI most GPU mining cost more then it brings. And I have not heard of anyone for a long time ROI when paying for cards mine with. |

thnx again  do u have a post with free bitcoin sites or vister sites?  "free bitcoin site" you need to look up faucets. And know it is a VERY small payment. You could work at them all day and get pennies if that. |

well, I finally received my antminer C1. It is all set with cooling kit and operational. But it does not work. The web interface does not show up.
If I manually set up a pool in conf file using ssh. It still keeps working for some unknown pool because the PSU is consuming 1000+watts.
Anyone has received it and has it working yet?
Yes i had one working and one with this exact problem. I uploaded the firmware to be helpful. Most likely you have a corrupt SD image. You will see dogie posted my upload here - https://bitcointalk.org/index.php?topic=841344.msg9389747#msg9389747 . I can say these are amazing quiet with cold ambient temperature. I would think most hosting companies would love these. So much less heat then Dragons and some older gen miners. If cold ambient these run like a dream and quiet. Have used free winter air to cool  |

Don't trust your Anti-virus software 100%. They don't work that great. http://www.forbes.com/sites/ciocentral/2014/05/21/duck-test-antivirus-software-wont-detect-advanced-malware/The caveat here is that it is possible that AV vendors can achieve better detection rates than those measured here because those vendors may use other external signals and/or more aggressive configurations to detect malware-like code and behavior. Nevertheless, simple analysis of the raw data reveals a significant trend of missed malware and slow detection rates:
On Day 0, only 51% of AV scanners detected new malware samples
It took an average of two days for at least one AV scanner to detect malware that went undetected on the first day
Detection rates bumped up to 61% after two weeks, indicating a common lag for AV signatures
In one year, no single AV scanner caught every new malware sample in even one of the test days
After a year, 10% of the scanners still do not detect some malware
The 1-percentile of malware least likely to be detected was undetected by the majority of AV scanners for months, and in some cases was never detected
I'm amazed at the amount of people saying don't worry. Always ask on software what is in it for maker.... this is free software... it says it will make you money essentially... sound to good to be true.. yes. |

I recently asked a question whether Tor can be used with web wallets with precautions to things like malicious exit nodes...didn't get any answers though.
Tor has had problems in the past with attacks on exit nodes. I would NEVER use anything important over it. Yes they fix it... and eventually another attack pops up. Don't risk it on your wallets. |

Watch out the site has pop-ups.... next time please use a better image site.
Yes those speeds are higher then normal. You could load firmware on it hoping it is software that i wrong. Be careful as always with flashing firmware. If that does not work then most likely the sensor is having problems. There are 2 sensors on S3 so you can still feel safe from not over heating is the good thing

Even though miners like me have good prices, these corporations have a advantage of putting their data center in very low electricity. I do agree low price will cause R+D of them to slow down. They will be much less likely to throw a few million at a new chip if price is so low. |

9 MH in scrypt is not a whole lot. It will be slow payout if that is what you are asking. And cloud so fees aswell.
If you want "quick" btc buy, only mine if have time. Always do ROI math cloud or not.
