Now they are trying to hide their shadiness by releasing S7 lite with lower hashrate!  I think they need to change this BM1385 chip in order to overcome with heating and efficiency issues. At least in S8 maybe!  That's just because that poster does not understand what that means and the miner consumption vs power consumption at the wall, there is nothing shaddy here, with the drop in hash rate, there is also a drop in power consumption. With a 90% eff psu that would come up to 1157watts at the wall~ down from 1240~ and the hashrate goes down at the same ratio. |

we cannot tell how much will BTC will be in 20 years
it may be 10$ and also may be 100K$
that is something that we can only expect but if we think in this range it would be good 10-25 have in reserve
I think the reasonable price is $100 or $1000 Not 100k or 10cent I myself trust in future bitcoin is something important at the world If bitcoin is still at 1k or less in 20 years it means it will have been failing and about to die, simple fact here. Bitcoin can't continue living unless it kick off another service from the global economy, and to do that it need to reach 5k and then 70k within 50 years or so, for the market cap into the trillions it will need to over take the every day services we use online. |

Some of the users on this forum made posts where they claim to get free power, where do they get this power from?
Some people get power included in rent - In some cases these people loose their free power when their landlord notices a much higher electric bill. Some people are students and dorm - limited free power from their dorm rooms Some people are in government housing. That the case for me, i'm in an apartment owned by a very big company, electric consumption is included in the monthly rent and it is typically cheaper for such landlords to just average out the electric consumption that way rather than install counters for every individual because the electricity here is ridiculously cheap. So what they do instead is fit the apartment with a couple of 120v 15A breakers and the panel can only support a smallish load after your big electricity spenders (heating, hot water, oven). And since its cold here 8 months a year, you don't need to pay anything for heating since you have tons of heat available from the ASICs. So anyways the maximum cost of electricity you could make use of is still a pretty low portion what you pay monthly. As such they don't even need to keep track since they own dozens of apartments in dozens of blocks all over. |

Someone already sent me $300 USD and I refunded it as soon as he asked.
If i was going to scam I would have kept it and left.
The problem is what you're saying, you haven't realized, probably, but something you said prove you don't know how what a S5 is/how it work. I also made you an offer you at which you never replied and also gave you an alternative. Would be pretty easy for you to take a pic of your miner next to a piece of paper with my forum name + your forum name + date on it and show it here if you're legit. |

Accepting PayPal or BTC for this.
It's been used for 1-2 hours max.
Price I'm taking for this is $300.
Hmu
NOTE: Only shipping to USA, UK & AUS
Why not Canada? Shipping is cheaper and and you just need to fill basic information on the shipment. If you change your mind, let me know.  He doesn't like Canadians! We are too nice for him. Also I think this may be a scam. He pm'ed me saying he would. I said i can't pick it up now, unless he want to "host it" at my place until i can pay him. I said to PM you if he wants a quick deal. So who knows, maybe he is not a scam, especially if he goes for escrow. |

offtopic question
How long you need to get the money back if you buy some s7?!
If you mean the return on investment, I would imagine that would be dependant on the price of bitcoin. Dipping to low you would not see the light of day making your money back on a purchase of one. BTC purchase (4BTC) to 4 BTC ROI is 5 month. Thats not counting deduction based on electricity cost, downtime, shipping cost and time and cost of PSU, etc. And the S7 on bitmain is sold out, otherwise at the lower BTC price, 4BTC is not too bad. However i still think its an expensive pick. |

I have just checked and instructions have improved over time. The ones in the S5+ & S7 User guide are the same and are ambiguous and as the OP found easily misinterpreted.  Also the instruction on the Website for the S5+ are equally unclear 3. Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to PSU to get power. When using several PSUs, be sure to power the hash boards first and the control board only after the hash boards have been powered. However the text on the Website for the S7 is relatively clear that the instruction only applies if you use a different PSU for hash boards and control board. 3. Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power. If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered. Rich Communication with Bitmain is not so good, at least in my experience. If you're not asking for support on a recently purchased miner and you do general inquiries or tell them to fix their stuff, then communication is kinda horrible. Its not hard to make it clear; "In the event you power the miner with more than one PSU, make sure no boards get powered after the controller." Which should make people understand as long as the boards are live before or at the same time, its fine. Controller just does not seem to support hot plugging blades. |

Who sold in the correction?? Now we've going back to $500. Hold on. Good time for buying.  No we're not going $500+ until halving, price will stay under $350 for a while i think.(hope i'm wrong) Probably not. The price fluctuate in a progressive fashion it look like. It was obligatory that after a while the price would drop sharply, having people hope it won't everytime is silly, its obligatory. It will always be up and down. Only the margin will be smaller as time go by. (And hopefully upward) If you look at the pattern from lowest to highest to lowest, we actually went exactly to expected price before dropping. It would make sense if BTC dropped to around last's slump then settle 20-30$ over. So about 260$. We're so close to 2016, i'm not sure we'll see the settling this year. |

Hi All,
Do all the Antminer s7 coupons work for the s7 batch 6 orders that are lower priced?
if so what's a fair price for it? I saw others giving them away earlier but now they all seem to want coin for em.
Cheers.
I sold mine for 0.1BTC when the prices were 1800USD per S7 with BTC at 230~ Kind of a moot point right now considering the S7 went out of order. Either Bitmain felt the price went too low and closed the listing or it sold out as 1250USD per S7 was an amazing price. |

There is no such thing as a "quiet" high flow fan, to get to the range of CFM they need to achieve decent cooling they HAVE to go with a fan that makes quite a bit of noise.
TANSTAAFL.
Ive replaced nearly all my fans with same or better cooling. And the noise is easily two to height time lower, so yea the one Bitmain use are not bad but they are very cheap and that is why they go with them, because its much more efficient cost wise to use those. |

Got paid 0.18BTC even though my page said 0.216BTC. Seems like everyone's post got limited this period.
Amph is paid everything. Check his stat. There is double standard. I wait and see will campaign managers increase rate fast like they decreased rate now when Bitcoin decrease in the price today. Nothing new, some users came through some sort of agreement and had double the limit. Probably has something to do for participating in the campaign for so long. |

I use Coinbase and i never heard of this. XT has very little support in term of hashrate, as such i don't really get what the point of the whole discussion is. I don't see what Coinbase actually has to do with this? Coinbase has no hashrate so whatever their political agenda would be, it is completely irrelevant.
In the first place, having bigger block means less tx fee, so i don't see how this benefit any companies or miners.

Thanks for the prompt responses...and especially the one on guiminer not being able to do it. Wasted a lot of time there.
It's a Phenom 4/8 core and 32GB ram...but I don't even try to use the CPU for this. It WILL do CPU mining, but it's slow as heck (of course) and stops everything else on the system.
I'll try the pool you noted, although I've looked at two "solo pools" so far, and one is already dead and the other one looks smarmy as heck.
Maybe there is a cgminer miner version you can use some -gpu argument or such. Honestly this is such a bad idea, that there is not really any work being done to support people who want to do this ongoingly. Even bad choices like buying a 5GH/s usb key that use virtually no power for 10$ is years ahead of what you want to do. Anyways, good luck; Days to generate one block mining solo: 3868327.82 Day(s) with your 400$ gpu. Yup...I did the math. I know...I'm utilizing what was available in that the R9 was donated; the main machine is my primary workstation, with a 1200w psu, and could care less. It's been paid for since '13. The exercise is re the process; it's giving a couple of folks something to do...a "mission". We're looking at some ASICs, maybe that low-end Antminer USB to start with. Not much cash to put in it, but that's probably a good thing. Peace. It doesnt really matter your past method of acquisition, what you have now, it doesn't change what would be a bad method or what a good direction to head from here would be. Whether you have free electricity or not, or you paid for what you have or not. I do have some free electricity too and i do lottery mining. There are simply good, bad and horrible way to go about it. And with how much heat you got for trying this, you can probably guess where your method would score on that scale. The best usb stick is this; https://bitcointalk.org/index.php?topic=1126705.0You even get a lightshow for free. For minimal lottery mining, this is great. However THE best way to go about it for you is probably a underclocked S1 at 275hz with a completely silent fan, pen modding the resistance down to 2.7. 140gh for 160 watts~ I got mine for 10$. Wont even have bother with running guiminer or cgminer or whichever miner that does gpu bitcoin mining. |

OK...first...please no lectures on "solo mining is useless" etc. I do understand.  Second...I'm making this new post because I've been at this for a couple of months now, have 50 yrs in IT and banking, and suddenly realize how much of a nooby I can be at 67. Thank you in advance for your patience. Anyway...I'm running a top-end mobo with a Radeon R9 290X and I've been getting consistent 825Mh/s rates with it on Slush's Pool. No problem. I really wish to do some solo mining. I've got two more R9s and mobos, and too much idle time, I guess (and I don't pay for my electricity). No matter what I do, it seems it won't happen. I've seen comments on other boards that anything past v.0.3.21 of Bitcoin Core will not support solo (I'm running the most recent). That would be a bummer. I've also tried just about every .conf and .ini configuration imaginable. I had some jpg's of the console, conf and ini files but can't figure out how to insert them here. I'll try to use text patches: Console msgs when trying to start the solo miner: 2015-11-10 14:27:59: Running command: poclbm.exe myusername:mypassword@localhost:8332 --device=0 --platform=0 --verbose -r1 2015-11-10 14:27:59: Listener for "Actual 1" started 2015-11-10 14:28:01: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:01, checking for stratum... 2015-11-10 14:28:01: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:01, started OpenCL miner on platform 0, device 0 (Hawaii) 2015-11-10 14:28:01: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:01, server error: Method not found 2015-11-10 14:28:01: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:01, no response to getwork, using as stratum 2015-11-10 14:28:11: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:11, Failed to subscribe 2015-11-10 14:28:13: Listener for "Actual 1": localhost:8332 10/11/2015 14:28:13, IO errors - 1, tolerance 2 2015-11-10 14:28:20: Listener for "Actual 1" shutting down (stopped it here) The bitcoin.conf: server=1 rpcuser=myusername rpcpassword=mypassword rpcport=8332 The poclbm.ini: { "profiles": [ { "username": "username", "balance_auth_token": "", "name": "Default", "hostname": "api2.bitcoin.cz", "external_path": "", "affinity_mask": 1, "flags": "", "autostart": false, "device": 0, "password": "pass", "port": "8332" }, { "username": "myusername", "balance_auth_token": "", "name": "Actual 1", "hostname": "localhost", "external_path": "", "affinity_mask": 1, "flags": "", "autostart": false, "device": 0, "password": "mypassword", "port": "8332" } ], "bitcoin_executable": "C:\\Program Files\\Bitcoin\\bitcoin-qt.exe", "show_console": true, "show_summary": false, "show_opencl_warning": true, "console_max_lines": 5000, "start_minimized": false, "blockchain_directory": "C:\\Users\\Caprica\\AppData\\Roaming\\Bitcoin", "window_position": [ 45, 329, 765, 288 ] The file paths have been checked and are accurate.

You could sell the gpu and get a great miner that would multiply your chances by 10 000, that would not break down because of the heat, cause noise or need to have its fans replaced all the time because they aren't meant to handle the load, assuming the VRM does not burn out because its not meant to be used 24/7 on such a heavy algo. |

just plug it in to one of the Tubes and no special way or mode to it in any way . nice to know for longer on , I'm still buying it or paying in few hours once the btc clear. i know his work or hope it does with no worry . and it's looking like , I'll be Drilling hole in a S1 or S5 heatsink, i have laying around to match, one of my PCB holes, i can't get a heatsink with the holes that match ,i dred that, being lazy. if anyone needs one and doesn't mind paying a lot go here https://www.wtcr.ca/catalog/product/bm-amuar-01. i all most did till i saw this on sell . they cost there . Wow that is super Expensive. So people must just know when buying stuff like this that you can get some cheaper. Maybe I need to start selling those LOL at 400 percent mark and still direct ship from amazon haha. Thats a bit crazy. However it would be very useful; "You can daisy chain up to 8 full Block Erupter Tubes or RockMiner T1s (32 modules total), or 4 full Prismas (16 modules total)!" Is there a cgminer and premade config for configuring each module individually? |

Going up a little bit:
Bitcoin Difficulty: 62,253,982,450
Estimated Next Difficulty: 64,938,500,384 (+4.31%)
Adjust time: After 122 Blocks, About 19.8 hours
Hashrate(?): 450,174,795 GH/s
Today is the 10th so I keep expecting to see a lot of Avalon hash added, but so far not near what I was expecting. I mean Mr. Lee was getting like 3 PH he announced, but I have not heard about sales yet in thread so I'm wondering if they are a little behind on shipping or making.j
Price is still better then the 230 but taking a little bit of a dive to 359.75 on coinbase so around 20 dollars down.
I keep expecting that too, but I'm wondering if like a lot of us, even the big players are maxed or close to maxed on power consumption and have to take some amount of equipment offline to put newer stuff on, so instead of seeing massive spikes, we're seeing a slow crawl with higher efficiency backing it. It's an interesting ride right now! I saw an S7 sell on eBay for >$2900 USD! Crazy pricing ATM.  I would love to get 2900 for one of my s-7's but ebay has so many returns. Ive actually had really good luck with it. Very good luck with miners on it compared to forums I normally get more off it. But I do only sale my old miners on there a new miner I agree is a lot of liability compared to one been used for 6 months. People tend to pay more when paypal is involved even though it can be a pain. I really understand the concerns about selling the S7 on ebay. The buyer's protection is easily abusable, even if the item is marked as no returns, if a buyer with ill intents buy the miner, they can buy it, mine with it for a while and then file a item not as described and return the miner to get a refund. Even though they may simply be a very small vocal minority, its probably a good thing to keep in mind. Not sure if there is a way around that but some users reported this. Basically without having some sort of "as is" agreement, the seller would take all the risks since the buyer can decide to abuse the system to return the miner if the miner drop in value. |

Are these still available from novak or anyone else?
And second question, you need one of these per miner or not?
I would be interested in buying 3 after Blazed get all that he need.

Reason why you need so many mid-priced PSUs is because each blade requires 3 PCIe connections and you CANT intermix them between boards, which mean an CX750W can only power 1 board.
A CX750* can power two hashing boards. But doesn't an S7 require all 3 PCIe connectors per board? Officially, yes. In reality, you should be very safe with 2 and you might be able to get away with 1(but dont do it), since by any mean thinkable, plugging 3 would be 100watts~ per connector is ridiculously overkill, 2 would be 150watts per connector and 1 would be 300 watts per. 300 watts is very limit, but with a small underclock i would think it would do just fine. Regardless always check your connectors regularly to make sure they are not heating up. So it comes down to the "warranty" if you do it, well, might not want to include that information if something unrelated break. |
