I already have a S5 controller so i'm just wondering if the S5 controller run the S5+ blades with the S5 firmware or it need to be flashed to something else.
And that user refuse to sell outside the US so i would need a seller that doesn't mind filling a 30 second form for shipping to Canada. So i cannot pick up that deal. Also 30cents per GH is a bit too expensive, especially when you add import/shipping costs.
Yes. it works with S5 controller. But I do not recommend the use it with S5 software. Or use at your own risk. With S5+ software you get six phantom blades with temp 0 and 3 normal blades with normal temp. If you tink, that 2,8 BTC for 2,5-2,7TH/s at 0.445J/GH miner is too expensive, then how much is in your opinion normal price for 2 x S5 2310 GH/s at 0.51J/GH ? The cheapest Canadian price for S5 I have seen here 300 USD , if you buy a whole batch. In what Province you live ?

Looking for confirmation here. Let say i buy 1/3rd of a S5+ without a controller, i CAN run those 3 blades of a regular S5 controller, right? All i need is flash the S5+ firmware on the BBB or?
There are posts where people have run it the other way. Tupsu would be the one to confirm about doing it this way. I would make sure before I laid the money out, but even if I had to buy an s5+ or S7 controller it would be worth it to me. If you have an S7 ordered you can certainly run them along with the S7 boards from the S7 controller. I definitely remember someone posting recently they ran S5+ boards using the S5 firmware. I have little doubt what you want to do will work. Regarding chip communication, the string design, the hardware interface, it is all the same. The S5+ simply introduced more ports on the controller when discussing anything in the context of what you are doing. If you know of someone selling S5+ hash boards please PM me as I am interested. I need to check out some places. You can buy here https://bitcointalk.org/index.php?topic=1178317.0 |

you think that is cheap?  Considering I bought them for $400-450, yes $375 is cheap and I am leaving in some room for negotiations. Plus, they are still profitable. Still profitable, but not for long. 1 TH/s Antminer S5 produced Today 0.0082 BTC if 100% pool Luck 0.0058 BTC with 70% pool Luck 0.003 BTC with 36% pool Luck Antpool 2015-09-21 produced a big minus for this day |

will it be possible to make these watercooled with c1 s3 s5 waterblocks?
thanks for anyone thaking the time to explore or anwser.
Why is this necessary? S5 is 0.51J/GH S5+ is 0.445J/GH Too little difference, too much of a concern about cooling. Yesterday I built another water-cooled S5. 2 x S5 in 2 x C1 housing welded together. 4 water blocks . Only on the one side is S5 blade and the other side water blocks is a small radiator of Antminer S3 . 2 x S3 Fan, syscooling SC-BC2 antiminer cooling kit radiator and pump. All 8 radiator fans work with 7.5 V. Water temp 35 krad Celcius. S5 software, FANs 1800 RPM at 34% Very quiet heater . |

... that the difference are 20 gh / s?
PS: do not worry about the thread, you can quit at any time
Why do you feel concerned about it, if the difference is only 20 gh / s ? Your math is terrible. Make yourself clear , how many GH/s is in one TH/s. The best you can do with your thread, is to put it in the lock. |

Yeah you are correct. I like the way bitmain reports correct numbers.
It is caused by greed. The only reason why they do it. They come back sales Tax from Chinese government from export. The part I don't get is how is it done out of greed? Isnt the vat/tax when mailed going to that goverment? I think customers are paying government the vat not bitmain. Am I wrong is the vat somehow going twords bitmains profit? Sales Tax in China is 17% Bitmain pays it , when buys something internally. From export declared sales tax will not be paid. That comes back from Chinese government. The more you export, the more you get back. |

S7 will make you a pile of money.
12 of them brings in about $3000-$4000 before electricity.
Nice thing is that it is half the power
Now every $100 I make I have to pay $50 in electricity.
With s7 you pay $25 in electricity.
Half the power needed half the heat
Win win
They will start to ship again next Friday
Until I can buy S5 for 0.8 BTC, it is still a bad investment. S5 1 TH/s earning is today 0.0082 BTC |

Doesn't really matter what Bitmain "commands" you to do or if they do it themselves. You are putting yourself at risk.
I wrote them, that I will send 2 x S5+ blades to him with the real customs value. 2/10 for 2300 USD I received a reply that if I do so, then it will be sent back to me. Therefore, I had no choice. |

All these posts complaining/suggesting that Bitmain should do fraud for their personal gain made me laugh.
They did it also in the past (up to February 2014)... I don't see how this is a good argument to legitimize a crime. Bitmain do not have any problem to cheat own country's customs. If Bitmain support commands you send 2 x Antminer S5+ blade with the declared value no more as 30 USD together and your parcel get lost , it is also good reason for laugh. |

But expecting Bitmain to continue RMA at their own cost and have spare part for miners 1 year after they have been sold, when the life run of an ASIC is like 6 months, is like saying a car should be on warranty for 15years at the manufacturer's cost. That simply... not... right. xD
What i'm saying is, if you can ROI a miner in 6 months, with how volatile the Bitcoin scene is at the moment, its probably a bad purchase from the start.
Bitmain simply lied about S5 spare parts.They are still in Stock: 610 Antminer S5 in Hashnest Shop. Price: 367.0 USD(1.53386348฿) Stock: 610 https://www.hashnest.com/hash_currencies/24/shopOwns Bitmain Hashnest or not? |

I have three S7's of which one stopped working after two days due to a defektive controller.
So I currently have three hash-boards and two fans for spare.
So whenever you encounter the misere of having a spare controller please let me know.

Depends on how rare they are. I sell 0.1 BTC a piece.
If you're interested -PM.
I've already paid 200 euros for shipping back to China S5+ blades, and they refuse to compensate shipping costs.

Estonia- only 20% VAT from price of the item and price of the shipping costs.
No other tax from Bitcoin Miner.
The declaration can be completed online, by logging in with your ID card.

people like this are why companies stop selling their miners to the public
And people, like you, are like sheep. I have 6 x S5+ blades shipped to China from DOA arriwed miner. Shipped at own costs and paid over 200 euro for shipping with EMS. Is it my fault , that they sent me old miner with old steel sheet housing , which was supposed to break with transport? This, after they were sent before to me 2 x S5+ in aluminum housing. Is it my fault that they forgot my last S5+ order which was paid with USD , and sent me the S5+ miner, that was bundled with three different batches from blades. They were not able to deliver them safely , even in China. See pictures here http://www.cybtc.com/article-1921-1.htmland say that it was their fault.  Click to enlarge
The only fault is to be so stupid, to buy again miner from Bitmain, and hope that this time be lucky . We are lab rats, who are paying for the tests at own pocket. |

Mine has two fan connectors, doesn't seems to be that one.
EDIT: also 4 blades connectors
This topic is pointless. If you are unable to read pins, then measure the difference between PCI-E plugs. Pictured are only one of 16 pin versions. There are also 16 pin version, with four data cable connectors and 2 fan connectors. Which is more common, than the one which is in the picture. Probably you have 18 pin version, however, it depends on the production time. I even got with the same batch and order botch version of miners a single shipment. |

Buy Block erupter cube ASIC 38gh/s miner and you get two compatible PCI-E sockets.
I think, that connectors from Asicminer Cube are not rated at 13A per contact... I used it for two cubes. No problems with original Y cables. This is true, I couldn't get the solder on my cube to liquify. I ended up just scraping off the melted plastic and calling it a day. You'll need to cut off the old plug and heat each leg separately . |
