The campaign is not closing down  That is good to hear. I really do like being in it which has caused me to stick around for more then a year. And build up trust with you. I know you will make it right are you able to say what re-formating your doing? Thanks addressing this though so we know not closing! |

Sorting through everything and will likely re-format the campaign. Thank you to everyone bearing with us! so it's closed for the time being? I'm afraid this basically means that you can kiss goodbye to your unpaid posts made since last bot-reset. You can kiss goodbye to my posts too if that comforts you somehow at least they payed one, but in theory they should pay the other if they do not want a negative trust.... currently 0.06 are missed Actually there was the bonus Coins_Bank mentioned to 1) 7/4 - Unpaid 2) Coins_Bank Bonus mentioned - Unpaid (unsure of amount) And if tomorrow will be 7/11 so a 2nd week of unpaid moving it to 3 unpaid items. I do agree Marco has always came through I have been in capaign over a year so interested to see what changes are on re-format. At one time payments were automated as long as hot wallet had BTC. I would love if we are caught up and re-format is going back to automation. |

Just wondering if anyone else is keeping an eye out on the pool hashing rate dropping in 30 minutes? I'll be shutting down a couple home miners (leaving the ones at work as the only ones on) after the halving and was curious if there would be enough people to show a drop in the pool hashing rate?
One thing to keep in mind is it is the weekend so some might not disconnect right after having. I did mine a little after as my S7 I now need to sell. But I can see some running for a while in hopes of price going up. I think old gear coming off could be a little slow. And really it is not home miners that will cause a huge drop, it is the bigger mining data-centers. A lot of home mining gear I think will come off, be sold to lower priced electricity or "free electricity" user. I know I have a S7 that will be sold. I expect it to be plugged in somewhere else so it will only be offline for a short time. |

Any possibility to upgrade the fans to quieter ones without losing cfm or compromising performance/cooling?
At stock speeds (of batch 1 anyway) the boards are pushing their absolute limit. With a moderate underclock I believe you could swap out the crazy loud fan for a 'normal' 120x35 which would bring the S9 back to S7 levels. It is worth noting if you do this you technically have voided warranty: "a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;" Don't know chances of getting caught but if honest that would void it. I personally would not risk it on a new S9. But if you do like dogie said underclock, and also make sure to monitor heat after and see how it does. During summer it can get hot some places. |

So I have 2x S7 mining and prior to the halving they were generating about .25 BTC every 10 days or so for the last month -- now post halving the estimated payout for them to generate the same .25 BTC is now 22 days.
Even given a scenario of free power, is it really worth it at this point?
It seems to me it would almost be worth it to sell the S7s right now and switch to an alt coin as there are some out there that would generate more BTC for the same power in a given time frame.
Anyone else having the same or similar thoughts -- or is there some piece of information that I'm missing?
I read speculation before the halving that people expect the difficulty to drop post halving, does anyone think this will still occur? The only way I see diff dropping is if miners pull out and global hash rate drops.
If you have free power yes it would be worth it to mine with. They are still good miner's that did not change over having. You just want to buy at a price over time you will ROI which with free electricity... should be not to hard to do. But if I had free electricity I would not have a problem mining 1 gen old gear S7 or Avalon 6's. But I need more efficiency as I pay for electricity at a decent price. |

Many issues now friends so great to have you guys back MMuch love from the "middle ranks" to the upper ranks of the sess pool known as BTC  Ok so unit 1 (the unit we are discussing) Is running stock psu. I am changing freq now. Will report back! Ok so unit 2 having massive problems. All boards are hashing. Will start running at 4.7th then will drop to like 1.3-2 and jsust sit there. Everything says hashing. I have the PSU's sitting on top of the units I am using bitmain psu's. I had them on top before in my old place, but i had them next to the deck breezeway so much more air. Pretty sure dogie is spot on. How do I move my psu's further? Bitmains cords are so fking short. Help?? What is heat in mining area? If you have two S7's, 2 PSU's, all in summer it could be hot in some places. So really need to know more right now all we can do is give general ideas of help. Are you able to take picture of area? Saying "I have the PSU's sitting on top of the units I am using bitmain psu's" could have so many setup's that is a very broad description. So need more info and temp's of area. Even screenshot of status screen of miner slowing down might help. |

I have been slowly getting rid of previous generation gear for a while at this point. Kept 1 S7 that I ran until today, which is now turned off. It will be for sell shortly. Now I really can only run S9's to remain profitable due to electricity cost. With near 10 cent electricity I just knew this was coming.... so started selling a while ago.
I also have Ether mining I have been messing with. So kinda been playing with that as I took S7's and A6's offline. Now I need to take some pictures of that last S7 and see what offers I get.

The bot it yet not been reset. Hope the payments for this week and last week are sent out soon.
I received ~0.02 BTC, which is less than half, was that the bonus & did others get a similar amount? No .02 here is that your payment you got on the 5th? I got my full payment for 6/27 on the 5th. So far where I'm sitting at is: There were two weeks that had not been paid: 1) 6/27 - Paid (no bot reset) 2) 7/4 - Unpaid 3) Coins_Bank Bonus mentioned - Unpaid (unsure of amount) I understand now, but I was expecting the whole amount currently showing on the "bot". Hopefully, the next one will come soon... With it being almost 3 weeks on that bot it is not going to be what show's up there. Backend I believe they can see what is in which period, as we have a limit of 100 post's each period. So your first payment should be accurate on 6/27. Just no bot rest/payment for 7/4 made it show a higher number (which has yet to be sent out). |

There are 3 different files, what is the difference between them? I have not found where is the changelog document. If you have it or someone I'll be glad to read it. Thanks The difference is the frequency different batches used different frequencies. You can tell in file name: s9-20160624- 650M.tar.gz So this one is for the 650 frequency. One that uses this is Batch 1 I believe. Look at Batch 7 - https://enshop.bitmain.com/productDetail.htm?pid=000201607061255410704Cf0TyV70656 you will see on spec - Default Frequency: 600M . So you would want the 600 frequency firmware s9-20160624- 600M.tar.gz . So check batch on default frequency before selecting firmware. As always be cautious during firmware updates don't restart during or other bad things. |

Too little hashrate for a solo to actually be anything but a lotto device with going forward that you are WASTING the money and only by the very slim chance would you see anything come back.
I know I can't justify it at my more "regular" electricity rate. I personally have ran lotto mining equipment but a S7 blow's all I have used away. I did U3's for a few month's with Crazy Guy's firmware on a R1 it was not bad and did not cost me much to run. I got a lot of my money back selling them after but I got a few month's to play with 3 I believe. At the same time I also used compacs they are great and I used very little power with them even with Y adapter and OC'ing. I sold most of them to I kept a prototype, review copy, and one production copy. Sold the rest as I just was losing interest of watching them after a while. Which is great as they moved on to new homes where people can enjoy them. I find lotto to be fun idea. But I just can't justify it personally with any sort of decent sized BTC machine. |

I've got probably 40 bare chassis around the shop as well for mostly the same reason. Gimme a few months and hopefully I'll have something good for you.
Very interesting any chassis specifically? There just is a lot of variance between some. But I look forward to seeing what you have coming up. One I have wondered about is all the A1 (Dragon's). There are a LOT of them out there and after having I would think lot will be offline gathering dust. There is the controller, and the PSU that easily reusable. But heatsinks, pcb's, chips, etc are really not worth much. So a lot of useless parts that I'm curious what the bigger mines that had them will do with them. Sit in corner? Scrap metal? Due to power efficiency I had to get rid of mine quiet a while ago. |

I think the guy will like to know which country has the cheapest electricity... I think China fits the bill quite right.
Cost of living is not as high as Brazil and the place is peaceful, you do not have lots of terrorists bombing places.
There are a lot of experts there who can easily put you through should you decide to join a mining pool.
But do you speak Chinese?
If you were to truly re-locate you could easily hire a translator, and learn the language (many way's to learn language). You might even find a partner or someone to work with that is local, as they might be able to bring a lot to the table as far as connections. All kinda depends on what size were talking about. I personally think re-locating is very very hard to do as there are a lot of financial factors in it, not to mention it get's complicated with going into a foreign country starting a business (some are easier then others). But I think hosting centers will remain king over people re-locating. I mean we just don't see threads of people re-locating in any big numbers due to difficulty. |

My math had difficulty dropping to 77-78% of current with a slow pull up through September.
HOLD bitcoin until 800...
EASY ROI by November...
Am I wrong???
EDIT: My electric is .058 -.096 KWH (variable spot market -- can spike higher if I'm not watching and careful)
I see the 1500ph becoming 1250ph. but WTF do i really know? None of us really know what will happen. My number is very simplistic and based on the last halving event. Phil, I think you've put more thought into the problem by trying to estimate the number of various models that will become unprofitable. That's definitely another way to look at it. One thing I do know is that it's very tempting to be overly optimistic regarding difficulty speculation. After being burned early on, I try to be disciplined and pessimistic. Although I too have been guilty of wiggling the difficulty down in the mining calculators, just to see if I can eke out ROI if the best case happens  Anyway, I don't want to turn this into a difficulty speculation thread though. Your difficulty guessing thread is the right place to talk about this. And on difficulty I'm a tad optimistic that some old gear will finally be taken offline. I think there are some that have been running a LONG time. Now these places will still have cheap electricity but hopefully some old gear comes down when new gear goes up. So I still think gear coming offline could be good for miners. But on the flip-side if they all upgrade.... could see bigger hashrate gain. But I'm hoping some go offline and do not upgrade. Do not know how realistic this is though as they have info-structure in most of these places.... so upgrades are likely. |

And when looking at this what you specifically will want to look at is minimum payout. Unless you have a lot of these stick miners, or mixing in with other gear it might take a while to meet some pool's minimum payout (depends on pools payout how it work's). Personally I did lotto pool most of the time when mining with compac. I actually have a few I need to plug back in, but other project's have been higher priority currently. But they are very right all of this is easy to google. |

I think if you relocate for other life related purposes while fulfilling your mining dream would be more realistic and practical to a positive outcome. However, relocation solely for mining is completely different. There are many factors you need to consider other than just electricity costs. For example, Venezuela has close to free electricity but the social environment there is not that great. Keep in mind electricity is only part of your operational cost that is against your operating revenue. Social stability, farm security, government regulations, financial reporting, etc are all ought to be considered carefully.
Like others suggested, cloud mining or hosting would provide you with the most peace of mind. If you really want to pursue your goal, I would suggest you find out where majority hosting companies located and decide from there. China is also a great place if you have good local relationship there.
The country picked is not a very realistic one for a big farm. I am not putting down Venezuela though, I have learned though the forums it has many people proud of their country that mine there - https://bitcointalk.org/index.php?topic=1231822.0 . But is is very very unstable looking from outside in (my personal opinion). I think more likely would be going to China, or part's of US or Canada. (I'm sure there are others). But the money needed to relocate, then add buying mining area, building mining area, and mining gear... it get's to a point you need to have a very good amount of money to do it. And it would be hard to do as your main job unless you invest a pretty big number here. |

Awesome setup Erumara!!! THANKS for the IDEA!!! Yeah -- it is EASY in the winter -- summer is when it is tough. But, unlike those number crunchers who doom and gloom each and EVERY year -- I am just THRILLED to get the latest and greatest miners added to my hobby. I've been mining since 2011, and although I've lost a lot of coin to Gox, Cloud Mining scam, blockchain, and others (not to be mentioned), I'm STILL way ahead. It is a VERY PROFITABLE hobby -- unlike MOST hobbies. If I lose THIS YEAR -- I'm STILL way ahead!!! That is the way I look at it... Summer mining is not that bad it just takes finding out what you need in your area. It is very location based as there are multiple way's for cooling, and different climates have best way's for them. I sadly am not in a place where evaporation cooling works in my weather. So I use lot's of CFM's of fan's in my mining area it took last summer to fine tune it in but this summer was easy with it all in place. So really just takes once on setting up for summer. And it depends on how many watt's of miners your running on how much heat you have to deal with. If not a lot of miners much easier. I have two big fan's and a professional gable fan that do good for my mining area. Again goes back to fine tuning I had to get a professional gable fan as regular house one's were just not exhausting enough heat for amount of miners I run sometimes. Here is my journey to find a good way to cool my miners - https://bitcointalk.org/index.php?topic=1020826.0 |

Hi all,
Here's my backstory: My Antminer S7 batch 7 units had 6 out of 9 boards burnt out within 2 months (back in January/Feburary). Since they were still covered under warranty, I sent them to Bitmain China to repair under the warranty, and spent about $200 shipping the boards for the RMA. It took one month to get the boards back from China after they were "repaired."
Within 30 days, the exact same boards I got back from china under the warranty burnt out again (I've got Batch 8 miners that have been absolutely great since day 1 with no issues). When I pulled out the boards from the miners, every single one of the boards I got back from China under warranty has heat sinks fall completely off.
Rather than go through that trouble again, I decided to send them to Bitmain USA and pay a fee based repair. (bitmainwarranty.com)
They were delivered on June 4th. One month and 4 days later, I still have no idea what's going on with my boards. The last time I heard from them was on June 30th when they said the advanced tech needed to take a look at them. They said the boards couldn't be repaired via normal repair process and needed a "deep repair."
First off, why were my RMA boards dead from bitmain china within a month after I got them back?
Secondly, why are those same boards unrepairable for Bitmain USA, and why is it so painful to get any response? I never overclocked them and ran them in a server room... my RMA'd boards should have never died again within 30 days.
5 of the 6 boards I sent had no burn marks and falling heatsinks. One of the 7 had a slight burn mark under one of the heatsinks. And yet all of them are "unrepairable" and need a "deep repair?"
Has anyone had luck with BitmainWarranty (US fee-based repair)?
The last time they posted on the forum was back in June 13th, so that doesn't make me feel any better.
They have very good service you can contact them through website - https://bitmainwarranty.com/contact/ , or there is even a phone number you can call on site. They are very quick on customer service. To my knowledge they can do all repairs that standard China route does, but on a much quicker time frame for those in or close to US. What way's have you tried to contact BitmainWarranty? They should be able to give you a much better anwser then us guessing but from my dealings with them they are very quick when I dealt with them. So I again suggest contacting them. Questions of OP: 1. First off, why were my RMA boards dead from bitmain china within a month after I got them back? We cannot give a good reason but I would look at your mining area as burning 6 out of 9 on initial is not normal. And if you got them back and still are burning them again something is wrong.... I would look at your mining area (PSU's, Electricity, Heat, Etc). It could be something on your side is common factor though going through so many boards. This is something you should ask BitmainWarranty if you sent them the boards as they can tell much more then our guesses on forum. 2. Secondly, why are those same boards unrepairable for Bitmain USA, and why is it so painful to get any response? I never overclocked them and ran them in a server room... my RMA'd boards should have never died again within 30 days. Look above and contact them though website or phone even. They are very quick every time I have dealt with them. But if they say it's un-repairable for them it would be un-repairable for standard China route to. They have full capability when doing repairs. But again best advice is to contact them as they know more then anyone on the forum of your situation. |

Yet a little more off topic. Since I don't know jack about eth:
"So i bought 1 btc worth of eth back on the presale"
Can you explain what this means? What is/was "the presale"? I assume this means that you gave somebody 1 BTC, and they gave you N "Ethers"? You then took those N "Ethers" and got back more than 1 BTC after some period of time?
Thanks for the education (If it's OK with Phil on his thread)!
I sadly did not buy in the pre-sale you can find some about it here - https://blog.ethereum.org/2014/07/22/launching-the-ether-sale/ . I would guess he's having an amazing day if he got into pre-sale account with 1 BTC. Price they say on blog "The price of ether is initially set to a discounted price of 2000 ETH per BTC, and will stay this way for 14 days before linearly declining to a final rate of 1337 ETH per BTC. The sale will last 42 days, concluding at 23:59 Zug time September 2." So he is having a great day to say the least if he invested 1 BTC. High risk and very very high reward. Either way big congratz d57heinz. |

Either you are in long term on the BTC game or you are out. BTC is a comercial game being runned by Chinese. You need to spend at least 50-100K on new generation gear every half a year to follow up on the farms in China, but you will never be as big becasue of power prices.
If the Chinese do not see this and react, it will evntual be the death of BTC because of centralisation, but kick me if the Chinese hasnt already seen that in the mirror.
The Bitmain CEO said 30-40% of the miners are exported. So there will be less concentration in the future. Do you have the source on this one? Also what was date out of curiosity? I have not see Bitmain talk about sells numbers much so would be interesting to read this. The problem with less concentration is the same places have low electricity price for the most part. That does not change on having low electricity so I don't see a big surge in less concentrated but I would be happy to be wrong. |
