I haven't used anything realted BitFury so I have some questions and will be glad if anyone answers me.
Can we upgrade antminer s9 boards with BitFury chips? Or only antminer s5 as writed in this thread? Has anyone ordered BitFury chips from seller from this thread? I understand if I'll change board than there won't be warranty but if I buy BitFury chips, will it have warranty? Also can I buy this chips from Official Bitfury?
No, the OP was proposing to design an entire board sized to fit in existing S5 miners (using the frame and fan, possibly the heatsinks, and perhaps the microcontroller). You can NOT just put Bitfury chips into anything else, they're not compatable that way at all. I'm sure if you wave $1 million under Bitfury's nose, they'll be glad to sell you chips. |
I'm no longer legendary just in my own mind!

The page is down Can you quote or tell us the news? It's up for me now. Seems like it's in russian, so I can't read it, though. I'll run it through google translate and see how much of it I can comprehend afterwards Edit From what I can see, it's modified S5 firmware on standard beaglebone, with a marker for efficiency and hashrate. Looks like 0.09J/GH at 3300 GHS or so, not terrible for a simple upgrade, to say the least. I can't read all of it, but from the pictures, it looks like prototypes are at least working now. S5 chassis isn't the most durable thing imo, but any progress is welcome. |

Yeah it worked now and I was able to look into this.
I contacted Hotmine and I try to create an order for 1x "X6 Miner", let's see what they say.
I would be happy to have a reliable European miner and support an European business.

Yep, working on mine right now. I didn't really glean anything from the text since I can't read Russian, but there was some valuable data in the pictures. I now have a better idea of the performance points of the Bitfury chip, since I haven't been able to test hardware yet. One of the drawbacks to being a solo operation, with product manufacture and maintaining a 100KW data center on top of design work, is that design can't always get done quickly.

Google translate link for it https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=https%3A%2F%2Fforum.bits.media%2Findex.php%3F%2Ftopic%2F30990-nabory-dlia-apgreida-antminer-s5-na-chipakh-bitfury%2F&edit-text=And damn fine point the article makes about PCIe connector ratings AND lifespan. All connectors have a rated mating-cycle lifespan. For most it is surprisingly few. Each you plug/unplug some of the plating and spring tension is lost increasing resistance. Point is connector ratings are based on being mated/unmated anywhere from just 1 to perhaps a dozen times. In the X5 link his solution is to tighten the female sockets EACH time before plugging in. Not bad but still not final solution which is to lower the max current per-pin. And um, even better, perhaps use silver flashed pins? edit: Also interesting in that it looks like they got it to work with the Bitmain GUI  So both share the same API's I take it? There has to be some driver translation somewhere... |

It's not bitmain gui, it's some open source modified router firmware. And API is likely cgminer's in both cases

Sorry, I forgot that bits.media has some trouble now related to moving from one hosting provider to another. Temporary solution is to add the following to your "hosts" file (if you are under Windows): 176.9.19.12 forum.bits.media
78.46.244.226 bits.media |

78.46.244.226 bits.media I got to read it. thanks 1 fast question. can you down clock and or under volt to get lower then .099 or .101 watts a gh? Say 2500 hash and 46 freq setting at .090 or .088 watts? |

According to this video https://www.youtube.com/watch?v=3zPpj1JYw38 one can go down to below 0.07 W per GH which for 52 chips and 40GH per chip is ~2TH Then the next one https://www.youtube.com/watch?v=zZPum2zqGPE shows that at 75GH per chip it is 0.086W per GH or 3.9TH with 52 chips As you can see X6 is advertised as 3.3TH and 0.1W/GH or ~18% increase, so 2.5TH at 0.09 W seems possible More 26-chip unregulated strings, same as the other thread.
The new (28nm and 16nm) chips do not have the current mirror circuit as the 55nm ones. My guess is that Bitfury went with builtin diodes protection only, which proved to be good enough with the 55nm |

Actually what I was getting at is, no intrinsic voltage control and a nominal core of 0.45V unless you can adjust at the PSU. So, like the S5, Avalon6 and 162-chip S7, undervolting is difficult and not an inherent feature.

These are not for sale anywhere yet?
Maybe PayPal would protect us if they never shipped?
Newbie here who buys 28NM equipment off seattles CL and ships it to Detroit
Thanks all for continued support

Still not available ? Any date ? Be patient, all technology takes time, and it's likely this is only a prototype and orders will take much more time to get filled. It should launch in a month. I'm really excited some other company that's not Avalon or Bitmain is making miners |
