I'd say it's worth trying new fans first or maybe swapping front ones to back seeing as you know the back ones work. Swap them over and see if they work on the front. If they do then it's just the fans that are dead
Also before swapping the one showing 0 is it not spinning? Just checking guessing so but good advice on swapping to see what it does. A good article I used a while ago when I had S4's was this: https://bitmain.zendesk.com/hc/en-us/articles/204199879-Antminer-S4-fan-specification-and-possible-replacement-fansIt has very good recommendations on fan replacements, and of course you could order from Bitmain or BitmainWarranty. I did try one of the Sanyo's long ago they do have more RPM. But guessing most stick with Delta's when replacing. |

Adjustable chip voltage and it will be a hit...
that would be the 4.1 design yeah if it would go as low as .085 watts and as high as .12watts it would have real value I am guessing they will design them for internal use in mind. I'm going to guess it will be closer to Avalon 6 and not have the voltage adjust ability we loved in 4.1. I hope I am wrong but I don't see them going back in design. We still don't know if they will sell to general public after being bought. Has any info on this part came out? I have not seen it but again I have had a busy week so could have missed it. |

With a budget like this you could buy a few S9 miners, and still have money for extra racks and fans.
I think this would be your best value, unless you have very low power costs and could find some used S7s.
(Since you could probably buy four or five S7s for the price of each S9)
The price of your power will determine your best route.
I want to know, how long for return of investment if we invest S9? And after halving day, is mining with this unit still profit? You can't make a blanket statement of mining is profitable or not. So many variables in it but largely electricity price. So again ROI time will very between people. You can do some math and see what it looks like for you at bitwisdom: https://bitcoinwisdom.com/bitcoin/calculatorWith that link you will see how much difficulty change effect's long term. No one can give you a exact date going that far out. Also if you pay in USD BTC value can make a big effect. So even payment method matter's when calculating. If you tell us your electricity we likely can give you a decent guess of possible ROI, but keep in mind it is just that possible not guaranteed. |

We could use a drop to 550 even to 480 usd. That could really drop difficulty a lot.
I purchased 300 worth of coin at 619 a few minutes ago.
at a 480 price 8 cent power is a loser for the s-7
that will knock out some farms
at the current 619 price an s-7 at 10 cent power earns 10 cents a day
I really want a btc price drop to the 480-550 price range
I'm still hoping for it to go up in value myself. Today was a drop for sure on Coinbase around 640 dropping to daily low of around 616, which was around 24 dollars. So it was not huge but still decent. But we have gone back up currently on Coinbase to 623 meaning in past 24 hours a drop of 17 or do dollars. So after rebound not a horrible drop. I have had a busy week so kinda less watching price then I normally do. But I consider myself a long term holder for the most part so dropping is not my goal even in short term. But hard to feel to bad when looking at current bitwisdom: Bitcoin Difficulty: 213,492,501,108 Estimated Next Difficulty: 199,586,743,634 (-6.51%) Adjust time: After 237 Blocks, About 1.8 days Hashrate(?): 1,453,881,284 GH/s |

I noticed the center board on one of my S9's was hashing 0.00 last night. It was still showing all O's across the ASIC chain for that board, but no hash.
I rebooted and it would come back hashing. But 30 minutes or so later, it would go back to 0.
The rebooting worked 2 or 3 times, but now the board is completely absent from the miner status page.
I have powered down a few times to see if it would come back but it didn't.
I tried to reset it a few minutes ago, but my few attempts at getting it to reset failed.
I can't try the reset again for a few hours as I had to shut down all my miners because of a major thunderstorm and my fans could suck in the pouring rain.
Any thoughts other than trying again to get it to reset? If the reset fails, would you suggest flashing as a possible solution? It's a batch 3.
Any suggestions welcome.
Thanks!
did you try to clock it lower? say 575 or 550? It was running at 575 today. I've got them on a schedule. When I can power them back up, I'll try a lower freq. Thanks! Out of curiosity what PSU are you using with it? Have you tried another PSU? Also have to ask with mention of schedule are you dealing with extreme heats? Scheduling tends to be for heat or sound just curious which one you are using for. |

I see. If that's the case, i think i should be getting APW3. As for power cord, is there any difference for power cords? I always thought that power cords are all the same.
<facepalm> The PSU end of the power cord is a standard IEC-13 connector. The wall end.... depends on what country you are in. There are a lot of flavors for the >200v plugs. The wall end also can depend a lot also worth mentioning a lot will change based on what PDU you use (assuming you use one). Not all PDU's use the same connector going into them so it's worth looking at when buying a PDU. I personally have PDUs between miners and wall in all 240 connection's I have. It is worth noting you can find some decent to great deals on PDU's on ebay from time to time. I owe phil for one he told me about once. But if your ever in market for PDU check ebay a lot as it tends to change on what is best deal. Can i ask what benefits does PDU provides? Do we need them? I will be honest some of your questions are a little scary to me. Is this something your wiring yourself? Or is wiring already there if so take a picture of plug and we can say more. What a PDU does is allow you to run one cable with a lot of amp's to power multiple miner's. This varies on your voltage and number of amps on which PDU is right for you if any, there are a lot of different options. But basically your PDU plug's into your power outlet and basically split's it where you can power multiple miner's from it (assuming power is there). *Edit Better description then mine I think is here - https://en.wikipedia.org/wiki/Power_distribution_unit |

Hello.
I was an user that only visited the forum and never commented, but now I kind of need it.
In the country I live the internet conection isn't stable. It goes off at least one time per day.
Does i need to reconfigure my antminer if my internet goes off for about an hour? or it will reconect immediately?
Thanks
A unstable internet connection is not a great thing, the miner should reconnect once internet comes back. But if you are experiencing daily outages it makes me question how reliable electricity is. Do you have electricity outages aswell? It does not take a lot of data being sent, but I would say latency you need to look at. If you are dropping lots of packets and very slow... possible issues all depends on how much. Also I have never experienced it but some have claimed certain miners without internet going crazy. Read about it as some claim it... again I have not experienced it but worth mentioning as amount that mentioned it on certain older models. |

If you're looking for hot and sexy, the days of Terraminer racks and the huge rackminer are gone now, replaced with the average-looking S9 and no other competition. I would suggest ETH or ETC mining right now as the fork may actually make ETC more profitable; the difficulty on the ETC chain is so ridiculously low I'm solo mining with a pair of R9 290Xs and hitting blocks. I'd look for RX 480s if you're going this path, but for now, there looks to be no big and sexy miners coming our way for now. The only good shit is the S9, and you'll need to buy a few to open a mine, and those are costly.
Personally I would go into both BTC and ETH mining currently. How much into each side... that is for op to decide. But I think BTC will remain king for foreseeable future so mining it if you can do profitable makes sense long term in my opinion. OP really needs to look at electricity and price of it where investing this will make or break mining. But as far as choice on BTC currently S9 is it for a lot of miner's. If cheap electricity S7's still a great machine. GPU's are a completely different beast. They are fun in my opinion to do and also GPU's do hold value decent till next gen knocks them down. And 400 series is pretty new so you could mine with it chances are and not lose much value and sell gear eventually. Lot's of potential for possible profit if you meet right conditions. |

The only problem I see with this is the fact that Bitmain has such a strong hold on the market. Unless they have an efficiency rivaling the S9's efficiency, it's unlikely that any major farms will sell for Avalons.
Unless Avalon makes these miners insanely efficient and has big features that rival the S9s, I don't see these being too popular with all the hype Bitmain has made already in the 16nm zone. Avalon has surprised us in the past, so it is still a possibility that they come up with something good this time. I hope their build quality is the same. Avalon actually made a very reliable miner out of the 4.1 and 6.
They also were purchased for a great deal of money on Avalon. Which leads us to think they have something worth buying... how far away who know's. Also with being purchased we really don't know if they will even mess with small sell's. I would imagine they would focus on getting internal mining up once they do have a new miner ready. The question then becomes if they do bulk sell's to big mines, and also if they do small sells to miners. With buyout we really do not know on this we can speculate but I don't think info has been released on this. |

Wish we had the reason behind drop, but hard to argue with it very nice change for us miner's. Also on value around 5 dollar or so up on coinbase (it went down for a little bit to high 640's, but went back up pretty soon after). Bot little gain on value and decent looking drop looks great to me.
I am hoping I am wrong on guess and it keeps going down on difficulty. Only thing that scares me is if it is someones upgrading. In that case could be a temporary drop and end up with a bigger hash rate in the end. Guess that would be the pessimistic possible view.
any crazy big s-9 upgrade is not sensible. but another miner like bitfury,avalon, insosilicon(sp) could do that. As long as the s-9 is the only working .1 watt machine bitmaintech can go slow and force all of us to go slow. they have no need to rush as we have past the ½ing and they are the only game in town The thing I keep thinking of is most of the "big mines" for lack of better term already have put in the money for info-structure. So I don't see a lot of them going away unless they go the way of say SP and go bankrupt. I think a lot of these mines will upgrade just depends when. And honestly some of these mines might be in places where electricity is so cheap a S7 upgrade might make sense in some cases. But I could be all off base on it with upgrades. I just am surprised on drop I thought we would have seen it sooner. But it is a little bit smaller drop on bitwisdom (although not by much).

I have not had any issue's with APW3's. They are what Bitmain recommends with S7/S9. I personally have followed this and not had any issues on the PSU side. They have kept working for quite a while now on some as I sold S7's and kept the APW3's. They can power even the batch 1 S9's which had the highest hashrate's.
There will always be market of server PSU's with breakout boards out there. But until I have a problem I will keep using APW3's as far as S9's at this point. I am not knocking some of kit's out there as I have not tested them. So just making clear not knocking them just saying what has worked good for me.
At this point a lot of my ATX psu's I had laying around from previous gen miner's went to mining Ether. I have had a decent variety of PSU's over the year's. If you have the 205V+ it is the one I would go for. If under the 205V then I would look at the EVGA Supernova 1600 you mention, as EVGA does have some great highend PSU's.
Thanks for your input. Can i ask how long have you been using those APW3s? The reason why im afraid to use APW3s is because i'm afraid that it would breakdown after the warranty expires. ... Since the launch of S7's, at that time I decided to use APW3's and so far I have not regretted it. They should last long after warranty if you have the luck I have had. A LOT of these psu's are out there and there are many user's. Also I figure Bitmain themself use them in internal mining facilities.... I don't think they would use them if big problems. So I don't think you will regret decision as long as you have 205V+ and use a proper power cord. You do provide your own cord for the APW3's as there are so many different options depending on setup/pdu/etc. |

Hello internet, I was in the market for a security system. I purchased one with no hard drive. A cheapo of amazon. 169$ 8 cams 720p reso. Not bad quality. The reason for this is because I reasoned it ineffective if a break in. A smart bugler would simply take the dvr with the HD and all the evidence. Not that it matters much because a smart one would also be wearing a mask. But at least security footage may help... I quickly realized after hookup that this one will not let me save to the could  I looked around the net and couldnt really find any that would. The only solution that i have really seen is to buy IP cams and run them through Ispy. However this renders my current system useless. Another option i considered was purchasing a video capture card. I could simply record the feed to the cloud or something. Well that was a no go as they are pricey as all hell. So i dont know what to do now. My last option was to purchase a cheap IP camera and see if i could somehow film the DVR monitor with all the cams, Anolog re-routing the video feed through ISP to upload to the cloud. Major problems with this also, including not as clear as id like. Latency. And at night the infareds turn on rendering the Analog screen viewing sequence useless. Any advice would be great. I may just be screwed here. May end up just using the system as a visual redundancy . Let me know what you think. Would love to figure out something to get recording and get to cloud. Kindest regards, I think camera's are great I personally use them, but most systems tend to have local storage... so if truly broken into not sure it is the best thing to catch it happening, or even alert you. I actually have been looking into upgrading my camera system to IP based camera's myself. Still early in the process though not really a big urge as my current camera's work fine... but some IP based ones would be nice when I do finally upgrade. Depending on what your looking at it can get pricey. I think you need to decide if your trying to catch video for after it happens, or if goal is to prevent it. If goal is to prevent it I think a standard security system is what you are really looking for I use one and it is much better then just having camera's in my opinion. You can set it and actually have a real security service alert authorities if something is happening when you are gone. So camera system is nice to be able to log into remotely and see what's happening. But I think a traditional security system is better then most camera system's. But it is going to be hard to justify the price and monthly service cost for most. I think camera's alone could possibly provide a false sense of security in a lot of cases. |

Hey everyone first time poster! So I have the chance to get an Antminer S5 for around $90 usd in perfect working condition. I have a psu already for it. And the cost of electricity for it is free! I will be running it in a dorm room and since I don't pay for the electricity, its free....well technically I already paid for it with the housing price but there's no additional charges for more electricity.
So is the S5 still a viable option for mining? I'm not by any means looking to make bank with it just something to let run for the next 3 years of when I'm in college and make some money lol.
I did not see anyone focus on this part but running for 3 years is pretty unrealistic. The S5 is already 3 generation's old at this point, so add 3 more years.... hard to say what will be out. I would say I would not plan on running it for 3 year's as even if it is still in working order chances are it will be very out of date. Also know the S5 really is not quiet or cool (speaking at running at default settings). So I also am not sure I would want it running in my dorm room. I have lived in dorm room's .... not the best place for a miner I personally left my miners at my home and did not bring to a dorm. Although I think I was GPU mining back them.... been a bit. But to make it short if you are planning to mine in 3 years in advance I would wait a while to get a miner for that. We really have no idea in 3 year's what current miner's will be like, so lot's of things up in the air. |

- My electricity price is " 0.1$ for each kilowatt "
That is bit higher price for longterm profitable mining. But with Antminer S9 you should be profitable maybe up to end of this year (based on the future difficulty which noone can predict perfectly half year in advance). Then you need to resell the S9 because you wont be profitable forewer with such high electricity price. I would not recommending it to you though as it is very risky because your looking for small profit only if all goes well (difficulty go up slowly, resell price of S9 still good after many months) and some loss if things go bad, especially resell price of S9 going too low. He could mine with a S9 for a while and hope to sell it eventually and ROI that way. But it is in no way a sure bet. I would check electricity though and make sure that all taxes and fee's are included in that. As if you get any higher I would advise finding a good hosting center vs actually mining at your location.Also keep in mind it is the summer month's in many locations, so add in cooling cost's in there. What type of location are you at as summer is very hard in certain area's. Also I'm assuming no vat/import? Check that as-well as it can kill ROI. I do not have the knowledge about mining but I think your starting capital was good. Enough to build at least 5 miner I think (that was approximation) and maybe the only thing you should put into is the right altcoin or bitcoin to mine and a good plan to make your project successful. Right now it's between S9 batches. But you will not get 5 miner S9 setup for 3-4K, just pretty off on that calculation. You need to add up S9's themself, PSU's, PDU, Wiring (depends), Cooling, etc. Just is going to be far different then your suggesting on amount of miner's. Also the "right altcoin" is really hard as not much is worth mining. Ether is pretty much what most mine on altcoin's, just makes sense when comparing altcoin mining ROI. But this is all completely different gear then BTC mining. If we are focusing on BTC mining as it sounds I bolded what I think OP should look into and check before spending any money. |

If your asking if you can build an ASIC that runs windows then no, you cannot. It takes tens of millions of dollars in fabrication and design costs to get an ASIC and you would need a team that knows what they are doing. I would look into the current manufactures and buy one to run in your house to start off.
It would be windows running the asic, not the asic running window's. There is not a chance any miner comes out that uses windows as OS. Window's has ran certain miner's and honestly it does not end well on the few that focused on window's. Only one I can think off the top of my head was a Scrypt miner the SF-28 that actually had a window's only support (at least when I owned it)... and it really did not end up well long term. You can use windows to learn with a compac. Sidehack posted above... he actually get's a ton of credit with making these usb stick miner's. With it you can learn a lot with cgminer and actually using commands. It is a fun project BUT before going window's route on it I would invest in a raspberry PI. There are great tutorial's and you can run it on a low cost controller this way vs a full windows machine. But in all honestly to OP most miner's at this point are pretty GUI. Look at any recent decent sized miner you will see you don't really design anything... it's already done and you really just put in your pool info. If your wanting to "build" an asic is not really for you possibly a Ether machine with GPU's if you really have the bug to build.... but that get's into a whole different topic. |
