That is a great link, thank you. I am going through it, a lot of posts. For one i tried a value for 200/60, and i get 12gh. Well still not quite there yet, but its better than 0, in the right direction. The other thing is i'm not downvolted as much as them so i'm not sure how that affect the required configuration. But i'm working on it. Also the turnpot resistor is dope. |

I bought the APW3-12-1600 PSU and the antminer S7.
I connected the PSU to the wall and that powered on just fine. The fan came on and it seems to be ok.
I then connected all 9 connections to the 3 hashing boards, as stated in the instructions which came with the S7, but nothing happened on the miner. No lights or no fans turning.
I tried connecting the last connection to the control board and that didn't do anything either.
I tried powering off the PSU with everything left connected and plugged back in and nothing.
So I started to look for a power switch on the unit and I looked at some pictures online and realized the button which I believe is the power button was pushed all the way in and stuck behind the metal plate which is right next to the QC sticker and Ethernet port.
I used a small nail to pry the button out from behind the metal, and that worked, and if I push the button I can feel a click, but the unit still doesn't turn on. I tried the same with the control board PCI-e connector disconnected and plugged it in after and still nothing.
I held down the button I freed up for over 10 seconds and nothing.
Anyone have any hints / tips for me?
1. that was not a power button, that was a reset button. don't know what happened to it after you "pried it out". 2. there is NO power button on S7 3. there is a power switch on PSU 4. did you switch the PSU off before connecting it to miner? I hope so. 5. Did you use 220V? It does not work on 110/120V Also he only mention 9 PCI-e plugs. There are 10. The controller need to be powered, which is how everything else is turned on. Please verify this is not simply the answer to the current problem, even tho so unlikely. Might be possible since he was trying to turn the reset switch into power on.  |

So, we just got a share that would of found us a block, but it was stale. The tooltip says "Share was submitted 1 minute too late." Does this mean the miner submitted too late to the pool late, or did we simply legit lost the propagation race?
The miner should never have been working on the stale work in the first place. The pool had informed all miners of the block change and the need to change work 69 seconds earlier. Older mining hardware/software is probably the reason - bear in mind this doesn't mean this miner is getting paid for stale work as his rejects are higher and they're not paid for. Thank you very much for the explanation. I get it now. It is unfortunate that this may happen because a miner's software did not react properly to the job change notification. Being one of our (new(?)) biggest miners here at Kano's C/K Pool, i hope jbravo will fix anything there is to fix, if there is something to fix and if it was simply just not a fluke. @Kano i see your reply just now. Thank you for the in depth log. Not changing job 1 min after a job change seem like the miner would be wasting a lot of shares. |

Yeah that one or the noctua...still I think the TwisterStorm has better stats and you may control manually the RPM Thanks for your time. I have the 3000 rpm noctua it is not that good on the s-5 ah yes ? Allright. The noctua and the TwisterStorm are about the same...Will wait to receive it and if it worth the shot ill make a review. Please do. On paper it look more performant than the S1 fans i use on some of my S5. Having a cooling upgrade while reducing noise produced would be a relief, but they look kind of flimsy compared to the fans that really does the job. |

Hmm, pools eh, what pools you run them on? Have you tried GHash.io? For some reason Tubes work best with ghash. Give that pool a try for a bit and see if they are stable.
So, they have not crashed once since then. I am pretty disappointed, even though not having to restart them at random is also a relief. I guess the miners are not in such a bad shape after all, but i'd really rather have a miner that can mine where i want it to mine. What a bother. Thus i decided to leave this thread open to see if i can get some more offers for these, if not i'll just let this thread die. |

HELLO EVERYONE GREETINGS FROM INDIA  i am young entrepreneur , looking forward to begin crypto-mining . can & will undertake bitcoin & other altcoins mining . i have been studying a little i understood about the required hardware and neccesary environment for effective mining . trouble is that i really do not have a programming background & understand absolutely nothing software part. i do understand about hardware and can certainly make simple math calculations . i want to start small / really small just to check if i can do it or not . what will be best for me to start with ? kindly guide. thank you Interfacing with your miners nowaday is as easy as checking your e-mails. The process is pretty simple. You connect to your miner using the web interface (with most miners using a controller), tell it where to mine, done. Tell the pool where to send the BTC, done. If you can mine or not, it depend on your electricity rate. Anything over 0.08$USD/kWh is bad. 0.06$ is decent, 0.02~0.03$ is great. Free is best. |

This community helped me alot, and also learned me how to make some buck on the side , so i want to contribute to all you guys. Ok, so here is my setup, and after a year there is still no major problem, only few miners show x from time to time, but no big deal! I'm reading all the time that all you guys have problems with burned out boards,PSU, everything! 1. ALL HAPPENS FROM POWER SPIKES and NOT REGULATED VOLTAGE! of course you will have to have professionally installed electrical installation, so if anything happens the "automatic power breaker" does the job! This is cheap way to go without UPS but still control your voltage spikes that do nasty stuff. I was logging the spikes in my house and saw that when the power outage occurs and when the power come back again, one time hit the 400V and our grid is 220V!! All electrical equipment have some tolerance for this spikes, BUT not for 400V AC, that is too much, the low voltage also make huge problems! Our equipment needs constant regulated voltage to operate in normal parameters. First see this picture  So i control the voltage spikes with the response time regulator which is set to 0.1sec, and my low threshold is 210VAC , high 242VAC, so when the power outage occurs the relay stops the voltage to the contactor and the power is out for the miners, so they don't get fried when the voltage spikes to haven, and when is back it turns on but only when the voltage is in my setup limits so only when is between 210<>242. This beautiful monitoring relay, watch that spikes and responds every time ON TIME! The main power is also going through 50AMP automatic breakers, my max amp per Phase is 64A. That's it guys, for ~0.5BTC you can do this setup and keep your equipment fresh and happy What would this do, for miners that are behind PSU with Under, Over, etc volt protection? As far as i understand, if a spike happen, the surge protector is supposed to catch it, and if the PSU's 12V output would fluctuate, the PSU protection would either stabilize it or shut itself down if it can't? Hereby protecting your miner from exploding due to the volt spiking dangerously. (?) |

I'm not sure what i think of that tweet. Why would having more efficient miners on stock prevent already centralized hashrate mines to acquire more hardware and continue to decentralize the hashrate?

With the halving upon the horizon, every ASIC manufacturer from Avalon to Zeus will have produced a great deal of hardware that has achieved "legacy" status. The question being posed is this; what happens when all utility from these machines lost? Take for example the Antminer S1, "the staple of the home miner" is how BITMAIN described the S1 and they were right... for the time. Currently the S1 only has utility to those that DIY and make custom solutions with the blades, or to those that want to mine for a incredibly small amount of BTC and use the unit for a heating source. As of today's date a S1 will make about 0.004 a week. In year or two, I don't think it would be unreasonable to assume that the utility of these devices will be rapidly approaching those of a USB stick miner today.
So the question is this; just what the hell do we we do with all of this old mining equipment? S1's can be had for 20-$30 shipped to your door now, people are basically selling them at a loss just to get rid of them. What happens this time next year? Do they just wind up in the dump because nobody wants them? The Atari 2600 can still play games, a 386 PC can still run applications that wont work on newer hardware, the miners of today on the same timeline....
Do you think ASIC manufactures should potentially begin a recycling process with their products? Apple will recycle their products free of charge as well many other tech companies today. We've seen USB miners made from recycled parts, why not create more? Maybe offer a slight discount / loyalty program and send in your outdated hardware and receive a discount on the newest models? What are your opinions? Thanks for reading!
Thats a good question / statement. It would be nice to see Bitmain take some S3's that are becoming more and more power hogs everyday, and to be able to get credit towards say an S7 miner. But they still sell right now for about $150 via eBay but by the time halving comes theyll drop dramatically. My suggestion: Sell them now, and keep a few or one for the history books to show your kids / grandchildren. That would never happen. Its cheaper to get brand new components than let say recycle the re-usable components on S1/S3 boards. Recyling stuff cost more money than just getting new stuff. Also if you re-use used PCB components, maybe you'll have things near death that still pass the check, but will die soon. I am not sure what that would do to the failure rate of the rebuilt miner. |

Ok comrades, my Antminer is slowing down and I need to figure out what her deal is. First, the details.
Miner Type: Antminer S5
Hostname: antMiner
Model: GNU/Linux
Hardware: 3.4.3.0
Power Source: Corsair CX 750
I remember when I first started this unit that it averaged about 1100Gh/s but now according to the system it's dwindled to about 555Gh/s. One of the first things I noted that was different was that the cooling fan shifts between speeds at random. One of the blades is showing a red light next to one of the power connectors.
Steps I've taken:
1. Reset the device
2. Increase the frequency from 350m to 400m.
Both yielded negative results. I'm requesting suggestions on what I should do next.
Thats half the speed, so i'm guessing its the common issue of a blade stopping to hash after a while. While it could be worsen by a bad PSU, it normally resolve itself. Did you try updating the firmware? 400m is too high, but on stock voltage, 393 should work for 1.29TH/s. |

So, at 193 or 200hz (the only 2 freq i have listed under 250hz) cgminer miner start but show 0 hashrate. For the skeptics that still need a screenshot; http://imgur.com/kWVVXXE #option 'freq_value' '0781' #200M #option 'chip_freq' '200' #option 'timeout' '70' #option 'freq_value' '4f02' #193M #option 'chip_freq' '193' #option 'timeout' '70' Both does not work, tested on different S1's, the same thing happen, they are penmodded to 2.8-3 ohm. My goal is to undervolt them to the max, rumored to go down to 90GH/s for 80watts, any input would be appreciated. |

why does your amazon link for 1000W PSU when power draw is 1100?
1100Watts at the wall would mean 1000w~DC, a PSU such as EVGA G2 1000w would do this fine. I don't know the corsairs much, but if they come from the same High quality OEM, like superflower or Seasonic, there would be 0 problem doing this. The only downside of doing 100% load on a PSU, is that you lose 1.5%~ efficiency or so compared to let say, paying an extra 100$ for a 1300w. |

Price at 449 currently.... it took a little dive  . Not fun to watch it go down. hopefully stays up as this difficulty needs it. I'm wondering what caused the downward trend any info out there on why? I don't know, just normal stuff i guess? If you look at; https://bitcoinwisdom.com/markets/btce/btcusd6, 4, 2, 1hour... its all the same. Goes up a bit, goes down a bit less, goes up a bit more, goes down a bit less, over and over. And this one right now is pretty small, so i'm not worried. |

Sounds like a smart idea. Would the Miners also benefit from another fan to help them push that hot toward the exhaust as the 120MM Fans can only push the hot air so far or would the exhaust fan pull enough air where it wouldn't matter and would already provide this extra circulation? Do you have a picture of your setup by any chance?
Not that would properly show this. But anyways, i have a Boxfan jammed IN the window, and the miners are almost against it, just a few CM away. The air pressure of the miners are actually very high, i can feel the air of the whole setup at 5m away (because right now its inverted for a reason not relevant to this). (This will produce noise because the exhaust of the miners will hit the fan) So anyways, if you point the exhaust of your mine toward the exhaust fan, you will have no problem, the fan you linked move plenty of air, you would not need a second one, unless you're blowing your S7's hot air all over the place, and even then it probably has enough CFM to cycle all the air you will need for 8KW. |

Hello,
i got some btc from a friend and i wanted to buy a bit hashing power on nicehash.
I want to mine in the antpool but i cant really find out how it works.
I have the Ips (there are 3 of them) and they put in in the example "antminer.1" but how do they pay me?
I have edited my account on the antpool with my btc adress but i cant add a worker only a "group".
Is it only possible to mine there with an antminer?
My antminer s3 is defect :/
Why would you want to rent hashrate at Nicehash at a premium, to then mine it on Antpool by paying a second premium, to mine some BTC back at a loss? Like you could put in 1BTC and you might get 0.85BTC back. Whats the point? Actually look at nicehash they have ran under price of BTC for quite a while. They are no where as good as once was on profit. It currently paying -5 percent of BTC mining... so why anyone mines there I don't know. But that with fee's there and pool fees in most cases you still lose money. Most that do it and gain are the ones who solo mine and are lucky. And some lose big with being unlucky. Because it goes from -2% to -5% which is cheaper than PPS and is effectively PPS. But Nicehash also take 2% on in and 2% on out. Then Antpool has "no fee" but keep all the TX fee = it has fees. So even at 100% luck you would lose out. |

Can checks be revoked? That would be bad because you can't get back your bitcoins right?
You're fine after it clears, which is why this is a kind of an issue. It takes time to clear, so this would be a very slow way to buy bitcoins. Therefore its going to be a very unpopular way of doing it. Not necessarily true there are a few possibility's that might be rare but can happen. Say someone is writing checks and forging name of someone else might pass... and person notice on billing cycle. There are other ones two. But yes clearing does help with most issues. When a check is cleared, you are guaranteed to keep your money, because the process of clearing the check is verifying if its a legit transaction in all aspect. Clearing is not equal to receiving your money. You actually receive the money before the check clears. This is because the banks legally have to give you the money within a week, but it actually take longer for a check to actually clear. So while you will receive the money after a few days in your account, if you want to legally spend it, you have to wait for the check to actually clear, which can take days to weeks longer. Because this literally takes forever, people don't use check for this. The seller would have to wait something like 3 weeks before releasing the BTC. This would be pretty pointless for the buyer as well. TLDR: Using Personal checks is bad for Bitcoins. But i guess a certified check would work fine. You would be right in most cases. I just don't believe in saying 100 percent all is true. In most cases yes clearing would be great and your all set, but I think of flaws. Say a payment from a check comes out that you did not authorize it's possible to get cleared by bank, you don't notice till next statement. There could be different reasons for this. Low possibility of it happening but it is not unheard of. But I can see your point on it being right almost all of the time. And I could be wrong I am not a banker so in no way expert in checks. That would mean that the check is counterfeit, and that they verified the counterfeit check and that it was verified to be legit, with a legit signature. I don't think thats possible, but if it happened, at that point they probably destroyed the check and it would be impossible to prove that it is. That would sound like a nightmare. Its not something that can happen with the electronic version, so i think this method should just get phased out of existence seeing how inefficient it is. |

So you think those 2 fans should be sufficient for this 100 SF Shed? I wanted the circulatory fan to help cool the Miners a bit too. They're both low wattage enough where it is still practical to use. Now I just need to figure out the best way to design the Exhaust FAN area outside to avoid rain or moisture coming in on strong rainy days.
P.S Would love to see other people's setup, lesson learns and what to avoid.
Well i can tell you why i was suggesting it that way. I can describe you my setup; I have my miners blowing the hot air directly into a box fan that is pushing the air out a window, this way waters can't get in anyways. If you do it this way you really wont need 2 fans. You should be coalescing your miner's exhaust to that output. It will make it so the first fan you pick to be completely overkill anyways. |

Your electricity cost is way, way too high then. You'd have to go for something more efficient and even then, if you can't ROI before the halving, you probably wont at all. You could run the Math with a S5, see if you can get your return before then.
I might be able to lower the electricity cost, but I don't want to count on that. I'm working on the "worst case". S5s are really harder to find. Given that, even with the halving, I will still gain a minimum by the difference. How much will difficulty increases affect the revenue? How are hardware prices related to halving? I know this is just the second one in history, but I guess that a mining machine, after the halving, will be much less valuable than now, isn't it? The halving is kind of distant right now, but when its close, a ton of people are going to dump their hardware. So whatever you get now, you need to plan to get your ROI before then. And for difficulty. A 100% raise equal a 50% loss in BTC income. Effectively the same as a halving. |

Considering 1.1 J/GH is still profitable here and i live in Canada, which is not a place with effectively free electricity like Venezuela, we still have a long way to go before 0.75J/GH become unprofitable. After all, many industrial setups have even cheaper electricity than be, where they can run 2 J/GH at the moment profitably.
With the BTC price rising, the difficulty will not only be sustainable at 95B but will most likely raise by another 30-50% during the next few months.
At a difficulty of 95,000,000,000 and with a Bitcoin worth around $450 you will earn roughly 10 cents per hour with one Terahash. So a 1.1 J/GH system will be economic to keep running if you pay less than about 9 cents per kWh. With a 2 J/GH system it would only be worth running if you pay less than 5 cents per kWh. The issue over the next few months is how far difficulty will rise as the large mining farm roll out their 16nm miners. I believe that with sub 0.1 J/GH 16nm systems appearing and systems such as the SP50 that a tripling in difficulty is possible before the halving. I'm at 0.06 so 2J is no good for me. However if i had industrial electricity the price would be 0.02~0.03~. So i'm guessing many place in the world has it for even cheaper and thats where most of the hashrate is. So it does not matter if all the home users stop using 0.75J/GH (its not actually the case) because is such a minority of the hashrate anyways. |
