I can tell you that bitmain instead recognize that if there is a fault in their products you change them as collateral, the problem lies in the distance, I am in Italy and last week I sent my pcb for replacement, now I and realized I was stuck in customs, because by mistake my wife has put a value of 100 euro, then surely they contacted the recipient had to pay and he refused, and then was blocked, now I have to wait for Monday to get in touch with and tnt solve the problem, some bitmain could already send me the new pcb, who still has not sent me
I am sure that you received the letter with same instructions : Bitmain, Apr 7,
Hi

I think this batch of 5 antminer s5 have problems, too many issues fall of power, I send to my pcb in serbia I paid $ 50, usually when a user sends in security should not pay anything, RMA exists for this, all payable by the seller, not the buyer
My 2 kg shipment to Serbia costs me less than 30 euros. Why do not you use a cheaper service? http://www.posteitaliane.post/english/index.shtml |

FTFY Tupsu Just kidding... I am sure if you have the money you can get some ASIC's. A lot of money.   |

...
Both purchases were made by BTC transfer, and my original idea was to post them as well. However, as it was delicate info and I pretended to do things correctly, I asked them permission to disclose that info. They allowed me to publish the order confirmation and invoices, but not the btc transfer because ]<<it is a document confirming a purchase. Distributing such information is regulated by Tax and Customs Board and without their approval it is forbidden to publish financial operations>>. It is really a pity I am not allowed to do so, and personally I don't think is the right way to do things, but in any trade agreement both parts have to agree to disclose that info. So it is their decision. Besides, by doing it I would break the terms and conditions, thus risking my purchase. And remember: in this stuff MY money is the only thing at risk.
Finally, I think I will not post anymore in the forum for a time. After I was treated here, I think that this community doesn’t deserve my help and my ideas. Frankly, I expected much more. I will make this follow-up of the purchase, just because I said I would do it. But I think I am mostly done here. I am really sad.
Happy mining, guys

Is there a guide to adjust so that it is running faster?
Thx.

Cries will not help here. I'm happy with my 40 TH/s Antminer S5. The best miner at the moment. |

I was told that for s5 overclocking voids the warranty, my miner was ..........
sorry if the question will void your warranty because putting this function?
Yes. However, you can erase your pictures and change posts. |

I reversed the blades and now it works, but the problem that remains in the blade where it goes attacked the controller remains burnt, so I should have a new blade guess right? but the thing that I do not admit is that I have to pay as well the Italian customs to get back garanzia.basta write a piece in the declaration hardware parts replaced under warranty because the product has already been paid previously
I got my parts with DPD direct From China . No VAT. artic mx-4 and not exceeding mx-2?
MX-4 is more expensive than the MX-2
now and reassembled, and the small 4-pin connector that goes from the blade hashboard
This is the controller's power cord. |

this morning I packed all the miner, and reversed the blades, and I reassembled everything and went back to work, the problem is gone, now it works again, but the problem that remains is that part of the blade is not working so if you were to burn well this the miner does not work anymore. What do you think I should do? bitamain should send a new blade, but I think this is impossible, that I definitely want to send him the blade, or all of the miner to review it, and spends much time in addition to spending more money to send the miner from italy up in china. what should i do?
I sent all my broken Antminer S5 parts to Bitmaintech (Serbia). Read more Bitmain tech support and warranty I used the MX-2 http://www.arctic.ac/us_en/mx-2.html65 g tube |

But if you could run 4 boards on the controller and figure how to get 10 volts to work with 2.2th hashing it would be a nice machine.

how does the new software work (more stable, less stable, no difference)?
thanks
...... The first software does not support 4 blade.
All of the following Bitmaintech S5 software versions supporting 3 or 4 blades at one S5 controller.

Youre right, but now i must scream at all corners this firmware for advanced users and blah blah blah. Sad, that people don't realize simple thing that this firmware not official, so no guarantee not to fry something  Btw that's the reason i think, why bitmain stay at cgminer 4.8.0 i should keep an eye on their github repo for updates Luckily my 4 blades all working , but I got more, as 120 degrees Celsius , after syscooling pump failure. This is the first time that I had to replace the hoses after miner overheating. I'm even pleasantly surprised, that all 4 blades survived. After remove the hoses, came out only hot steam and boiling water The warranty is only 90 days , shipped 2015-01-13. So is warranty already over. I have several S5 built to 4 blades. Water-cooled and also the air-cooled models. 2,3 TH/s miner is better than the 1,15 TH/s, if I have a total of 35 Antminer S5. The only problem is that You began to modify Bitmaintech first S5 software. The first software does not support 4 blade. All of the following Bitmaintech S5 software versions supporting 3 or 4 blades at one S5 controller. |

You're doing right reminding people about that they can loose warranty. I live in Russia so warranty for me is usless and i know how such things works, so i can repair it easly, as i mentioned i don't care 1. With Four blade, he can not turn itself off at 80 degrees. 2. This soft is not been able to work with three-or four-blade . example http://www.perearstike.ee/S5/4.blade.Sm.jpg |

Can the 18pin data cable be replaced/purchased? getting 1 hw error per minute. have narrowed down to one of the data cable
Presumably, this is not a data cable fault. I got a different longere cables from inside broken TVs. (plasma and LCD) 16 pin and 24 pin . With awl You can take out the cables from one plug and place to another plug. So I made a longere cable. |

You can use new S5 Hash PCB ( 18 pin connector) with S5 Control PCB (16 pin connectors) Need only a 16 pin cable.
But what if I have S5 control PCB (18 pin connectors) and S5 hashing blades (16 pin connectors and 16 pin cables)? Can I use them together and if yes - than how?.. Bitmain was not able to give me an answer... You Need S5 Control PCB with 16 pin connectors. I have some spare ... |

I'm sure it depends on which board. You should contact them to see if they have the model in stock. They were very helpful when I needed one. I cant remember how much but it was a fair price and plus shipping I believe. They were very nice and very quick. I was surprised how quick I do remember that .
