Bitfury would be the same price as us ($20 per GH/s). With the recent run-up in BTC price, you're no longer at $20 per GH/s. Only if you pay in BTCs, the 25Gh/s board still costs $500.00. the 25GH board easily overclocks to 35GH for most users |

i think the doubling every month will continue until mid-janruary, at which point the market/blockchain will be so full of hardware that even filling preorders like cointerra wont have the massive hit to difficulty like right now.
that said, i really want to see some better pricing on h-boards next month. for 30-35GH operation, 2.5BTC is fair for november 15th delivery

Guys, looking for someone with a version 1 M board and successfully running 4 or more H cards
I have 4 cards, without problems most of the time. More are arriving later today. wow, I have two stubborn version 1 M boards, that just wont hash properly with more than 3 H cards. What is your hashrate with 4 cards? Are you using the chainminer that came with the board? Any special settings? Thanks in advance. 138.5 GH total, but 3 chips are dead (2 bypassed and 1 at the end of the chain). I overvolted them to an average of 0.78v. I'm using the stock software. Autotune is off, and some chips are set to 54 and some to 55, based on manual testing. drop the tuning to 53/54, ands increase the voltage to 0.805V. youll get a little bit faster speeds from increasing the voltage/tuning ratio rather than vice-versa |

I recently bought this as a hub for 4 little singles and 4 of MrTeal's chili boards. It has a molex connector and 2 usb connectors that go to the extra usb connections on your motherboard. When I plug in the molex and plug in the power supply (have not yet hit the power on the motherboard) the CPU fan starts to spin... Yes, the cpu fan is spinning even when the computer is turned off... Is this dangerous? Or is this not a big deal and it's just the extra power from the molex feeding back through the USB connectors on the motherboard and all will be fine once there are devices connected on the hub? Should I try to simply run it without the molex? I'm really not sure that little singles need a powered hub? I would really appreciate your help. Thank you. as a hub only (BFL stuff grabs power elsewhere) you can skip the molex connector. whats happening is that the 5v feed is being pushed from the hub to your pc's usb ports. i had a similar powered hub that actually grabbed power from my laptop's usb port and pushed it to the [turned off] psu, causing its fan to spin. |

I'm sick of starting over everytime an SD card gets confused. Could somebody give me a step by step procedure on how to make a new imaged SD card using the the Pi and the SD card it is running on? I have a USB SD card adapter that i can plug into the Pi. My goal is to have several backup SD cards that i can just replace the current one with should it get confused. SD cards are cheap. Also, how do you set the time on these things, i'm tired of living in the past.  i made an sd card image using my desktop and some software. it *might* be easier then searching for the corretc linux scripts to handle the task if you are not well-versed in linux/RPi |

So it's prob smart to cancel Oct pre-order now and wait for November immediately available order?
once all the october kits and cards are shipped, i expect/hope we will see a drop to <2.5BTC/h-board with immediate availability. This would mesh well with the promise of 2.25BTC store credit on the delayed august stuff
I dont think Dave will have anything for Nov. That's my concern. its all up in the air. my method is to add boards from each batch if the price is right. (The october batch is profitable IMO - i got it when it was $450 by creditcard, and if it overclocks to 40GH like my first card then i anticipate it producing >3.5BTC) |

I hand it to Dave a BitFury for getting the August orders out the door when promised (most all). But since then
communication, follow up and product competitiveness have all fallen badly. This despite the fact he has 2 office people.
At this point it appears the GB's for the USB miners and the Drillbit System group have the upper hand in customer service and likely ship dates for those that want a more reasonable price and need to order now or have ordered in the past month or so.
I would love to pick up some H-Cards (at a reasonable price) to fill my V1.0 M board. But it sure does not look likely.
the price right now is the same its been since august, because it would be entirely wrong and unethical to change the price for the october batch before all preorders are filled. once all the october kits and cards are shipped, i expect/hope we will see a drop to <2.5BTC/h-board with immediate availability. This would mesh well with the promise of 2.25BTC store credit on the delayed august stuff |

Punin - do you guys plan on selling any more chips?
With bitcoin difficulty shooting through the roof this current pricing is a fantasy and not worth even looking at.
Even if chips get delivered tomorrow and get through assembly in just two weeks (good luck with that) and start hashing on Nov/1 they'll barely make $15 in their entire life ... and that's excluding all possible expenses and having free electricity.
I'm speaking from a system integrator's point and all I can say is that the next two weeks would be the last time ever when those chips could be worth any hassle.
To put those chips to work takes on average another $5-10 per chip in components and other materials alone. And it takes precious time - around 3 weeks at best. You probably don't need me to tell you that - you know better than me the pain of manufacturing stuff. You guys are still shipping stuff that was ordered months ago.
My suggestion to everyone in the bitfury team - unless you want to use them as tiling for your bathroom please throw all remaining quantities for sale as soon as possible.
At $1-$3/chip this would be their last gasp.
Past November/15 you might as well use them as a paper weight.
Let's give the BitFury Gen-1 chips a decent final and not make it another Avalon.
is it hard to understand that the current pricing is how it is because it is for the october batch, and was set over 2months ago? once the pre-orders are filled, they promised to ship from in-hand stock and this would enable them to adjust prices weekly if required. bitfury is one of the better designs available right now for power use and simplicity, and it would not be difficult to keep bringing the price down every few weeks until around $50 per h-board which is probably what it costs to manufacture. bitfury devices will outrun avalon (gen 1 & 2), BFL, asicminer, and knc in terms of power use (~1w/GH at 2GH per chip) |

I have the latest version of chainminer. How could not detecting all the chips not be a main board issues? It happens no matter what cards I use in bank 4, but is fine if i just populate banks 1-3.
I already examined the boards and a friend of mine examined them under a microscope. No visible issues.
Ive tried everything basically, its fucked. Its unstable as hell, I can leave it come back an hour later and the entire 2nd bank will have crashed...
Card regularly dip from 30gh down to 2-3 then back up again, is that normal? (Running on manual)
the drops can be caused by inadequate cooling, particularly of the regulators IMO. as for the slot causing the issue that is possible but in the past often corrected by rearranging the cards. if some of the chips on the board (i assume 1-13 of the 16) are visible, it suggests that the last 3 are a h-board issue rather than m-board, at least from some of the august batch feedback. however, it may be possible that the 4th bank on the m-board is simply far enough down the chain/away from the PSU that the current/power perhaps is not totally stable/sufficient. try running without the 2 bad cards and see how your overall stability is affected. if your hashrate and chip error rates seem better (keep an eye on miso and spi errors moreso than hw errors) it may indicate the m-board is either unable to provide power correctly to the slots/bank, or the physical slots may be unworking. |

I think a lot if people will be waiting until next week when Dave gets the new V2 H boards and V3 M boards. I have some low order numbers but I think they'll be shipping me the new versions although I would gladly accepted old style H boards as part of my orders if I could have had them this week.
i think so. my order #13X for a single h-board shipped wednesday and is expected to deliver tomorrow |

I'm not an illustrater, but i do remember reading somewhere that if you modify a certain percentage of an image, it isn't a rip off, it is fair use. Many illustraters start with an existing image and modify it to fit their purpose. I see nothing wrong with this. You people are crazy.  all they did was change the name, add an led, and add an lcd. thats not a major modification, its a blantant ripoff and unlike what will be made. show of hands, who expects the final product to be roughly 12x12x8cm like they displayed for weeks (months) on the site? |

40GH/s and 70w per board!? Wow.
That means a full 16-board set should be able to do 640 GH/s at 1120w.
I have a 1250w power supply. I hope thats good enough
Maybe I'll aim for 37.5 GH/s per board and hopefully around 1000w
I'm pretty sure you can't run that much through 2x 6pin connectors. Good point! But you could spread those 16 H boards across two M boards. Ugh, I had an extra M board on order but I canceled it. The M board kit is $1300 with just 1 H board so it really isn't worth it. I'm on the verge of canceling my order. Bitfury from megabigbpower is showing the worst ROI right now, when compared to BitBurner, HashFast, and KNC, especially if a 16-board kit can only do 500 GH/s or so. It needs to be able to do 600 GH/s and arrive in the next week to justify it's $8k cost. I know that the chips are actually capable of doing 800 GH/s as my BitBurner with half the chips can do 400GH/s. The power regulator and cooling issues will limit it though, as for the fact there are only 2 6pin connectors. I'm guessing those two connectors limits it to 600w maybe? I cancelled my extra m-board as well. You could just hook extra power to the m-board but I have a feeling it doesn't work that way. Thinking of canceling my unshipped order if I do not get a ship notice tomorrow. There really is no RIO now at the price I paid. waiting until the final days efore shipping to cancel is a bit of a bold (dick) move. BFSB held up their august promise, and again is holding up their October promise. |

Hi, I cannot seem to get onto that IRC server, some reason my ISP or something is banned...weird.
Anyway I have tried
- 2 new psu's
- new pi
- new SD card
- BFG miner
- Manual and auto speeds
- swapping card orders ( on multiple occasions)
- Increased cooling
- Decreased cooling
Oh 2 of my boards are totally buggered, this has been verified by someone else with a fury who I sent the cards to to double check.
However any help getting the rest of them working stably is appreciated.
if 253/256 chips are seen, the m-board is not the issue. try the following: 1) check that the newest chainminer is loaded (it *should* be, but who knows. the easy way to guess is look at the error rates. if over 4% you are on the old chainminer) 2) check the traces and soldering on the boards for any issues. 3) try a slight pencil mod on the boards. it may sound unlikely, but i had some poor-performance chips that responded well to increased voltage. 4) resort to exchanging the boards (but expect punin to take some time getting to this, since hes busy clearing the remaining october orders and likely dozens of similar email requests for help. its entiely possible to have bad boards, but there was a lot of troubleshooting advice and methods that were seen following the august batch. |

Its a pitty you do not answer your emails. I have sent several and am still waiting a reply. My main board isnt working 100% and 2 of my H-cards are junk, 1 stuck at 10ghs one around 16ghs.
Chance of ROI is gone now, pretty furious at the customer service.
There is never anyone on the IRC channel either.
Joke.
try switching around the boards to put the weak ones at the end of the board. what is the issue: poor-performance chips or chips not showing up? |

I'm pretty sure you can't run that much through 2x 6pin connectors. If the power supply is a single rail design, why not? If not, maybe I can figure out a way to add more connectors. Or do we risk blowing out the M-board? What is the max speed that could reasonably be overclocked to with a 16-board setup? 6-pin pci-e is rated at 150w per line, but in reality it can handle significantly more based on the cable thickness. i would say between 2 connectors, 500-700w would be safe with a good PSU. (dont know if the m-board has limits though) with all 16 cards, i doubt 40GH could be reached on each card due to heat density. 35GH would be more realistic, and at that speed it would probably require 45w per card. |

anyone who rips off another site's image is likely unethical already if not a scammer.
besides the fact that any mining machine that is not much bigger than a PC mouse is going to be 'too small' to be profitable with all the casing, lcd, etc. |

YOU ARE ALL WRONG
ALL ASICS MAKE PERFECT ROI
YOU JUST HAVE TO KNOW HOW TO DO IT
FOR SOME REASON THE INSTRUCTIONS SAID TURN IT ON AND HASH AND MAKE LOADZZZ OF MONEY
WELL THE INSTRUCTIONS CAME FROM THE CHINESE MANUFACTURERS who can't write english well
THE CORRECT INSTRUCTIONS WERE BUY AND SELL TO OTHER PEOPLE ON EBAY FOR AS MUCH AS POSSIBLE
IF YOU HAD FOLLOWED THE CORRECT INSTRUCTIONS YOU WOULD HAVE MADE LOADZZ OF FREE MONEY
AND PLENTY OF ROI
JUST MY 0.02BTC
you might be right, but with all the bolded shouting and spelling errors its hard to tell if you are smart or on crack |

Oh give Josh a break. From Jody's last blog entry:
"March is heavily populated with orders. We are shipping a lot even though we are moving slowly through the days."
How could Josh possibly have foreseen that?
uhhh, because he has access to that information way back in....MARCH josh and BFL cannot play coy any longer. Bitfury and [almost] KNC have filled months of preorders in a single week or 2 weeks |

the USB cable was not included, but i had another one. This should not be an issue I suppose
i think he was referring to cables inside the unit. last time i saw pictures of a minirig interior, wiring was a mess of hotglue, zipties, electrical tape, and velcro tape. im hoping they are improved since, but its possible an internal power or usb cable popped free. when you plug it in and turn it on, what happens? are the fans spinning, nexus turning on, heat being produced, etc? there are a hundred different reasons why it might not connect, but with a little more info it can be narrowed down to 5 or fewer |

How overclockable are the boards that are being shipped now? Is the power regulator still the limiting factor? Has anyone tried to replace it with one that can handle more power?
It's power reg + heat removal. My regulator was overheating like crazy at 41GH/s. The board would mine for a few mins but the regulator would turn off and I had to reset it everytime. I think the board was drawing around 70W power. I think with adequate cooling of chips + regulator, these boards can reach 40 - 42GH/s. this. my regulator *seemed* to be staying on, but chips would drop like flies and the board often needed a reset. with heatsinks on the back of the regulator though, im now able to handle 40+/-1 GHash as for heatsinks, i would advise against the massive slab mentioned a few posts up. at 12mm thick, you almost certainly will not be able to put a card in every slot, and the weight of such a big slab may mess up the cards unless they're braced. Look for something in the 6-8mm thickness - I found some terrific heatsinks that were 35x35x6mm and each one perfectly covers 4 chips (4 heatsinks per board + mini heatsinks for regulator). These do a great job pulling away the heat and there is space to fill the slot behind ps: my order 13X h-board shipped today, and expected delivery is friday 5pm - fingers crossed for a weekend of hashing  |
