which is uncompetitive if people are looking at just $$ mining alt coins on 1070s or 1080ti's has a much faster ROI and better resale down the road.
I just gotta know how much crack you are smoking to think you can ROI with a 1080Ti faster than an ASIC at the insane markup prices the GPU market is experiencing. Thank you, while GPU mining has it's benefits it's far from the end all be all. I repeatedly see these sockpuppets posting about how GPU is the only way... It's not, it is just a different tool-set. |

AH! OK, I thought you were referencing the URL bitmainwarranty  I logged in and reached the support site no problem, but I do not have a ticket open. Maybe email their support address and see what's up. |

Oh this is board only...Silly me... Yea i found the PSUs around 199$ but its only 750-1400W, there arent 2k+ W  But you can run multiples (just read the warnings and set it up right when doing so), $199 is too high for a server PSU. I'd search around eBay for used 750-1100W. Here's an 1100w for $40.00, probably can find better with some more throughout searching. https://goo.gl/FuKT6z |

myrig.com is NOT related to Bitmain
Neither is bitmainwarranty. Do you mean support.bitmain.com? Can you post the link you're talking about? |

Sent my Antminer D3 for repair, now that i check the status it says error 404. Is it just me or everyone because it seems very suspicious it only happens right when the D3 has arrived.
I think they are in the process or renaming to myrig.com I bet someone forgot to set up a redirect |

Uhmmm do i see those numbers really good? 2400W for 55$? That is really cheap... for price of 1 Bitmains + shipment, i can buy 3 of this.... Thanks for this! TIL!
You'll still need a server PSU But yeah those can be had for pretty cheap, they are rated to run 24/7, and are usually at least Gold rated. |

Thanks for the replies. The ebay seller provided an invoice today:  Does this look legit? My understanding of the order process with Bitmain is you must watch Twitter for them to tweet about a batch and then you must go to the link they provide and commit before they are all sold out which happens in minutes. Is this correct? And you must pay by either USD wire transfer or BCH? So they showed you an invoice, but that proves nothing. For all you know they've been mining since late Dec early Jan. You do have to keep an eye on Bitmain, Twitter, Facebook, and the Telegram bot along with this forum will help you a lot. |

Damn those are some scary numbers! :O Thats almost 40% of them are dead. I know that you shouldn't be cheap in therms of PSU, but which PSU is in same/similar price range(but better quality(not sure am i being cheap here)) then Bitmains? Some 1800W PSUs are around 400$ in my country which is rather...x3-x4 times more expensive then Bitmains...
A lot of folks are using server PSUs with breakout boards from https://www.parallelminer.com/product/x11-breakout-board-adapter/ or eBay. My preference would be Parallelminer's version. |

how come?
Is my only option to run the fans at 100% all the time?
In my specific scenario I have a lot of antminers and need to keep my overall temperature low for the time being
In my opinion you're going about this wrong. Generally you address the cooling issue rather than try to modify the miner to run at a lower hashrate. Do you truly see the fans at 100% in the status page? What are your miner temps? Where are you keeping these miners? |

Noted.... In the future don't use Bitmain PSU's.... I knew they were suspect, but this is really bad performance. If it's one or two units then not really a big deal, but when spread across an 800 unit deployment it definitely has an impact on our engineering for this particular deployment.
I wonder if it is the PSU or the miner? Maybe swap a PSU from a 1.4 over to a 1.5 and see what happens? |

I had an order due January 21-30th and it actually showed up just after Christmas, pretty much a full month early.
Same, I think this is a lesson on why you should only order via Bitmain directly. |

Is that not within the +/- 10%?  Actually on edit the OPs #'s ARE outside the 10% for a 13.5. But I would chalk it up to prod variances, yes it's disappointing for sure. |

Is it possible to configure bmminer to aim for a target temperature by throttling the antminer?
I see that cgminer as a bitmain-temp parameter but when i do bmminer --help on the antminer this parameter does not seem to show up.
Any ideas?
You don't want to throttle the hashrate, that's what the fan logic is for. |

Yes, the homework is done. Looking for actual hardware. Though if you have experience and any tips - will only be welcomed!!
Only way to buy a Antminer and keep your warranty. https://shop.bitmain.com/main.htm?lang=en |

Don't want to rain on anybody's parade, by the Xilinx SoC (System on Chip) is the controller for the S9, not anything related to the SHA-256 hashing chips. They could readily replace the Xylinx with something compatible and still retain the rest of S9 frame and hashing boards. I don't think this says anything about a possible S11 miner. Absolutely, which is why I simply stated future. It's just nice to glean some (any) sort of news about our favorite vendor |

So the last time the OP responded was Dec 3rd. Either he's counting his money or...

3 phase is different, but if you simply use 2 pole breakers and leave the 3rd leg alone it's no biggie.
disagree that is not balanced. and depending on the transforms it can be an issue Interesting, I have a 200A 3 phase panel, only my AC is actually 3 phase. Everything else uses 2 pole breakers and is fine, including my sub-panel. Not arguing, just saying. don't know your transformer that feeds it. If it is from the street to the panel the transformer on the pole is bigger then what I linked. if it is in-house maNY COMPANIES HAVE 3 OR 4 LIKE I LINKED leading to sub panels. balanced OK, sorry, yeah I did not follow the link. Yes mine is straight from the pole to the building. |
