Where are you located?
If youre in the US then you could try Bitmain Warranty in the states.
I am not in the US, but is way closer and cheaper than hong kong, sorry but I wasn't aware there is a bitmain dealer in the US, I just open the ticket and that's what they told me, just send them back. how do I contact bitmain in the US? Here is there profile on the forum:- https://bitcointalk.org/index.php?action=profile;u=383527All contact info is there  |

Two lots of negative feedback on your profile and you want to trade with PayPal which is reversible. Btc isn't reversible. . I doubt you will find anyone to trade with but good luck.

Ja. Glad I ordered my (probably last) s9 yesterday. This will make 8 of them and hopefully it will be as good as most of the others have been. It already started shipping so should show up Thurs or Fri methinks. Too bad the R4 never came up for sale -- I'd rather have gotten 2 of those for space heating use... I hope they do come back up for sale I'm hoping to get one if I mine enough on my current setup  |

Noise is not quiet!! Quiet Miner be R4 Has anyone turned the fan speed down on their S9? Just how quiet can you get it? Im asking as im considering one for home (currently have an S7LN) and ambient temperature isn't a problem so overheating wont be either. Just thinking that an S9 would have more resale potential if I decide to give up on mining.
Yes but the resale value of an R4 is probably not as good as the S9. Also with the S9 I can run one board at a time and keep two as spares (due to limited amount of power I can use). But the noise is the factor. Hence why I asked if anyone has turned the fans down at all and what the volume is like. |

I wasn't aware they had an amazon store I thought they only sold direct through their website  |

I wonder if these batches are going to be more reliable? Also strange to suddenly have very precise hashing figures compared to previous batches of all miners.

My voltages are 0.776, 0.780 and 0.779, but I keeping getting bad hash rates using the cgminer-gekko-win32 in Windows 10 x64.  Doesn't look like you ran that very long before waiting for a screenshot. I get the expected hashtags at a given frequency on a raspberry pi 3. |

R4's are more efficient than S7's you want S9's to be really profitable.

I'd say your having a psu problem then as the voltage drops too much when it trys to start hashing.
Yes that is correct but when i connect only control board with PSU then it is not stopping When hash board are conected then for little time it will work well then it will on off like in video which i shared The control board is only using about 100w or something the main draw are the hashing boards. That's what's putting the psu under strain. Have you got a psu that is definitely working properly that you could swap? |

You need your price per KWh if you know it.

Send it back to bitmain if it's still under warranty.
It is of S9 batch 2 so it is not under warranty Only option is to send it to bitmainwarranty in the USA and pay for a repair. |

I assume you are going to mine an altcoin as mining Bitcoin with a computer is outdated by years |

This should be in the hardware section really But to answer your question thoroughly you need to tell us your electricity cost. |
