Right now it's winter so it's much easier on cooling down then winter. How many watt's of gear are you powering? I used a heck of a lot of CFM's to move hot air through my hobby mine during the summer: https://bitcointalk.org/index.php?topic=1020826.0 The good news is I now have enough cooling gear to make it through summers without a problem now. |

Hi
I have the same problem.. So i instold antminer s7. i used apw3-12-1600w(PSU). I connecting my miner directly to a router via class 5, I use Ip Reporter to get an ip number. I made sure that the ethernet cord is firmly attached and connected 1600W PSU(s) to the miner. Sorry for my English and thanks anyway!
So is unit powering on? We need to know if this is power problem or ethernet problem. What voltage are you plugging that PSU into? If it is on what is your normal IP range for your network? This could be a problem if using a different subset of IP's then it's static. |

Hi everyone , can you pls make a step by step tutorial (main tasks) what i need to make bitcoin maining pool from start to the end .
thank you
Have you thought about using a solo pool that is already out there? For example CK's pool - https://bitcointalk.org/index.php?topic=763510.0It is set up has the hardware running for a BTC solo pool. If you are thinking you will make pool and profit chances are slim. If your thinking for learning... then I could see that. But it's not going to bring you profit. |

I was except the front plug is on fire hot now on the same board. Just the wires are hot to the touch while the opposite board shows no sign of heat.
Unplug it don't run if it's "fire hot". If you do this it's just going to melt the last one and you are literally playing with fire. Best thing would be to find someone who is able to solder decent, and have them put a new PCIe plug on the melted on. If you cant find local might ask on board. But don't run it "fire hot" unless your just looking for trouble. |

I opened a survey to ascertain the statements that bitmain send at customs, but no one is voting, this is bad, because we can save money,
we all know that governments steal of all, this is because each one of us does not notice, or does not care, or is convinced that the seller kind bitmain declares the right,
but are we really sure about all this?
Snip
I got the the heart of it. I don't think it's that no one cares it's just that it's the government that has high vat/import tax. You can get mad at bitmain for making it full value or what it is declared.... but at end of day it is the government who is making you pay crazy import tax. With you being in Europe it is quite high in a lot of places. I personally would suggest a lot of Europe on big miners to find a data center outside of Europe. You can question and pool all you want it won't change your governments import tax. No matter who files it in or what it's filled out to the government is one getting the tax. And I don't mean to seem un-caring. I think it stinks for EU miners on import/vat taxes. I wish it was cheaper so it was easier to mine there. Im all for people beiong able mining. But my wishing it was cheaper does not change governments taxes. |

you think those temps are okay? I don't but maybe I am wrong. Batch 8 with a slight OC. Anything higher raises the errors above .01  I would want to know ambient temp. But that is getting up there. What does it run not OC'ed?? I to think it is most likely to high. I don't think Batch 8 was made to OC as much as some might want it to, it simply is already very high on frequency. And it's sure not worth losing warranty for a slight OC. |

does bitmain still have a warranty place in the USA? I remember when i had my S5's they had warranty services on the USA out of colorado i think. anyone know if they still do warranty stuff or is it all china now? Edit: found "BitmainWarranty" on here. in there sig it says you can return stuff to CO Bitmain Tech Support & Warranty: +1-844-BIT-MAIN (844-248-6246) Skype: BitmainEnglish (Voice Only) E-mail: support@bitmain.zendesk.com Теперь сервисное обслуживание доступно на Русском и Украинском языках! Return Address: Bitmain Warranty 3700 Quebec Street, Unit 100-239, Denver, Colorado 80207, USAI don't think that will do you any good as far as returns. You might speak with them on phone, but you will still be RMA'ing to China. There are some who have claimed to buy from them and pay extra and are able to use them... but I was not ever 100 percent sure on that. But you can ask them I'm willing to bet they still have you ship it from china. *Edit looks like hawkfish007 confirmed this |

my bad, too much time wasted in bed watching tv series  sorry and thank you! 453.45$ => diff going up! loved btc at 220bucks!  What I like is earning money in 220ish day's and holding... and it doubles. Now that is a great feeling vs if I had it in my regular low risk checking account it would have made almost no interest. But there is a lot more risk. I hope we see it go up even more. I really think with China being a big part with their stock doing kinda crappy we might have more from there looking at holding BTC. |

If this is true, I would kill for this opportunity. If you truly have free electricity, it's a no brainer in my opinion. I would probably invest in S7's, you get warranty, better GH/J, and more GH/m2. If you are not limited by m2/squaremeters, and could get used S5+ from a trusted source, it would probably be a good idea to get some, as they probably give better GH/$. Surely you have a limit on your free power? In that case I would go for the S7's. Btw, if this real, I want in.  I do have a limit but it is huge i gotta have 50 s7 running at least to get to the point where the flat tariff we pay rises Even then here electricity is 0,003$ kwh with no limits. And thats an industrial facility in an industrial zone we pay even less than 0,003 wich is almost paying nothing ALSO in Venezuela there is a Currency Exchange strict control but there is a huge currency black market if u have any meanings to earn foreign currency you can live like a king here Problem here is security but like i said it is a facility with guards and CCTV, alarms etc etc. I was checking a lot of 16 SP20 fore sale what you guys thing of SP20 vs S5? he made me an offer of 16 SP20 with PSU included for 6072$ i made the calculations with a 8% difficulty increar only a monthly 2% raise of BTC price and i break even in 6 months and taking into consideration a halve of blocks in july i still can make 3000$ by january 2017 Im thinking of starting with a small investment of 15 or 20 Antminers S5 or make a big investment (At least for me) of 20 Antminers S7 PD: I would love in a future if i can run a succesful farm to host other ppl miners for a fee i have everything in place in that facility to do it easily thats how i got interested in bitcoin mining I would start off smaller personally. To go from no miners to 20 of anything.... is a lot of growing pains. You will need proper electricity wiring, and cooling. I don't think a normal factory has been setup for bitcoin mining so you will need to make a area most likely if you have 20 miners going. Is it 220/240? Do you need to wire the electricity? Add breakers or other things? Do you have PDU's the list goes on and on. But try a few and see how it goes... then build up if it works good. Don't start with 20 with being new to mining. All this ^ Plus S7s, you can get a few and have more hashing power, less power use, less gear needed, learn some stuff about miners than think bigger after a trial period. He is in a country with extremely cheap (not the most reliable) electricity. Part of reason I say start low is just the power alone I don't think he will be setup for 20 S7's. Now if his warehouse really does have a lot of power... and he can get it wired then he could try it out and move quickly. But I do think he underestimates the amount of planning and setup needed for that much electricity. The cooling alone I think will be something he has never dealt with. Also did not mention but with location security would be huge. Do you have guards 24x7 there? That is just a country I would not invest big in if there was not good security. |

the next step would be to see how many wattage this place can deliver, and how much is your investment
then you can go ahead and buy a s7, don't bother with other asic, as they require more wattage, which mean more psu
Avalon 6 has a group buy it looks like currently that might be worth looking at if stuck on 110/120. But your right if they are able to power the S7 it is cheaper as far as hash currently. I think he needs to figure out the wattage like you said though. Unless his line is 220/240 I think one modern miner will use most of his "2 power outlets but are on the same power line" |

By your standard (less than 8c/KWH) my electric is cheap - yet I've NEVER had any of the calculations I've done show that the S7 will ever pay off. Usually not even all that close to doing so.
VERY VERY cheap (3c or under) maybe, though right now even at the way-too-late drop in S7 pricing it's still looking VERY iffy.
NOT 7.5c
I would agree on cheap being closer to 3C or so. The big guys can chase this electricity price and build where ever they find it. This is why they have a huge advantage. Some gear even at halving at 3C chances are they still can run. Us more "regular" user's would be 8-10 cents or so I think. And above 10 get's tough unless your one of those who say's they use it for heat in winter... then it get's a little more complex. Unless they own their own land or building (millions in capital expenditures, not including equipment) including the maintenance and real estate taxes that would add .02 to .03 to whatever wholesale rate they are paying for electricity this is where the small guy doesnt have that over head, however the small guys cannot get .03-.-6 electricity rates. Yes but these big guys can invest once in land/building and a lot of the setup. Then they can re-use that and replace gear when needed. So a lot of it is a one time investment. And on electricity they are getting some of the lowest there is out there. They actually build with this in mind on most I believe and find cheap electricity before starting an operation. And overhead get's paid of pretty quick with these mega mines. Your not thinking of the scale they run. We are not talking a few machines, were talking a ton. So they are a huge amount of hash. |

So, magically I remembered my dad installed a 240v outlet in our garage. I'm going to get a 240v cord which can handle the total amperage, only thing I need to figure out is if that outlet can deliver up to 3000W. Now I just have to extend ethernet to the garage.....
I would suggest asking your dad if he installed it. I would suspect he knows if you have the amps to pull it off or not. But finding that out is important. Is this 240 connected to your main? Or is it a subpanal? But that is your next step to look into it more. |

I tried that and it simply won't turn on without all 4 boards plugged in. I also tried moving the remaining three connectors to different places and no luck, still won't turn on. I have the latest firmware too if that makes any difference.
eta: I tried something potentially risky and swapped the controller with another C1 that has 4 good boards. Seems to have fixed it. It works now with any combination of boards connected with the other controller. Kinda strange but I'm not complaining. Thanks for the input VirosaGITS. I appreciate it.
My C1 was able to run with a board down. I had one that eventually had 1 board I could not get fixed, and one that was hit/miss. But I'm pretty sure I was able to unconnected the ones that didn't work (it's been a while). Eventually I parted out on it, and made more then I thought I would. I have no idea on market no compared to then but you might look at parting it out. |

I have been running my B3s since I got them, they are almost out of warentee - then I get to play with them in "other" ways.
One thing I'd like to play with is running more hashboards per controller, to free up some controllers for"other experiments".
What I'm looking for, for the "other experiments".....
***** BURNT BOARDS ... I've seen some pics of just BBQ'ed board... I'd like to play around with those. Don't pick at the boards, don't pull the wires, cut the wires if the connectors seem to be stuck.
***** DEAD BOARDS, the ones showing all --------------- I would like to also play around with those.
It does not matter what batch they are from. I just want the hashboards, not the whole unit unless the whole unit is crispy cooked and not easily disassembled.
Please keep in mind these burnt/dead boards are just scrap as they sit - the only value of those boards is gold recovery value... or a memento of wasted money & bad luck.
Since I do not have any burnt or dead boards of my own, I'm going to need some that I can play with to see if I can help the rest of the S7 community with developing a process to recover some, most, maybe, just maybe all hashrate.
If anyone has a board or two that I can "play around with", maybe finding a work around to get these operational again, please let me know what you have and what you would want for the boards.
Thank you

Most burnt/dead board i saw had recoverable chips, which would make the board pretty valuable. Just something to keep in mind. Also Bitmain used to buy back bad boards at a good price for the same reason i presume. Yes, Bitmain may buy back the boards to "refurbish" and stick into later batches or use as warentee replacements. BUT the end of the production run has arrived, That buyback may not be available. As for recoverable chips, yes, the chips contain gold. A very minute amount of gold. But, unless you know how to extract that gold, which happens to be a toxic, very hazardous and creates hazardous waste extraction process - not something to do in the home.... and have a significant amount of the chips, that ~VALUABLE~ aspect is out of reach of most people. Sure you and take the burnt/dead boards to a scrap buyer, get a few $ per pound, or donate/sell the boards to me and I'll try to come up with a process or method to help the S7 community to repair/reuse their out of warentee boards to get them hashing again. Winter is here, I need a project while I hibernate in the basement workshop. Thanks bbOOmm Wisconsin, USA Those chips could become next generation sidehack sticks. If you are interested, someone is selling an entire dead S7 on eBay http://www.ebay.com/itm/Bitmain-Antminer-S7-Bitcoin-Miner-4-73TH-s-AS-IS-/301840247762?hash=item464714abd2:g:Ig8AAOSw3KFWfF22I would be a little careful on that one the seller say's it was not diagnosed but he has sold other miners. I am thinking he likely tried to diagnose.- http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=acuratlny&&_trksid=p2047675.l2560&rt=nc&iid=301840247762&sspagename=VIP%3Afeedback&ftab=FeedbackAsSellerI would suspect he tried to fix it and knows a little more hes saying (but that is speculation). I don't know how he would know just 1 board shorted with out trying to diagnose. I think anyone would try to do a few things to see if controller works, move to boards, etc. I find it hard to sell with 0 looking into fix. But your right if just wanting chips it could be decent for that. |

i really doubt he can hit the block the second year, the average for one block for a single s7 is very bad
assuming no diff increase one s7 right now can hit a block on a average of 1111+ days, this mean 3 years at least...
There is a reason why some call solo mining "lotto mining" the odds are against you. It is not something you can really justify I don't think with 1 S7. I would pool mine it as I said before. Only if a decent hobby mining operation can pay for 1 doing it for fun would I even look at it. Even then I still personally don't solo mine anything that big. I stick with U3's and compacs. Those I can do for cheap on solo mining. |

It is better to buy S7. It might still be useful after the difficulty rise and block halving. It is more efficient than old generations.
There is so many different factors like electricity price, if customs, if using 110/120 or 220/240. It is not one size fit's all. Some are better off with S7. But if cheap electricity good chance a older one would be better. They can get it cheaper and might ROI. If they can ROI on a old one quicker that is where they should go. But again this is very different for different people. |
