2) Haven't found in FAQ what October delivery means: beginning of October, mid-October or until the end of October. It makes hell of a difference when monthly diff increase is in a range of 60+% (and maybe much more). Is there any explicit punin's statement about this?
Punin stated that first orders will be shipped in the early October or even late September (!), if you place your order now it should ship in second half of October. |

I have received my Full Kit toady. After dealing with BFL the quality of service provided by punin is almost unbelievable.
Regarding hardware. The setup was nice and easy, everything went smooth. But after hashing for several minutes hashrate was dropping drastically, I was forced to stop and restart the miner. Furthermore BTCGuild showed only half of Kit's hashrate. Switching to Eligius Pool helped. Now everything runs great and stable.

@Bitweasil: Which GPU's are you using in your racks, that they are able to keep acceptable temps while spaced so tight?

I have purchased new hardware and I am looking to see if anyone wants my old setup, please keep the pricing reasonable and I will aim to be reasonable on my end. I can ship out Next Business Day and overnight it to Canada/USA. Could be yours tomorrow.... Details: 100 x USB erupters ( I think I may have 2-4 additional ones above the 100, which I will also include) 1 x Erupter Blade OC'd with Fan already mounted on it.. Does a solid 12.7GH/s (Could include Power Supply as well if needed.. 850Watt Silverstone currently in use) 12 x USB Hubs 7 x New 5V 5Amp AC Adapters 1 x USB FAN OPTIONAL - Could include the wireframe rack seen in the picture. https://bitcointalk.org/index.php?topic=7216.msg2947922#msg2947922 Let me know if you have any other questions... Prefer Bitcoins, but open to options/trades etc.... Maybe a bunch of video cards? Wrong subforum. This is not marketplace... |

BitFury has a large team of engineers all working to deploy boards. There's is a different board design from ours. Different production line, etc. That group is doing pretty well bringing up their hashpower, which you can see at ghash.io.
Our boards have just begun to ship from the factory in China, and we will turn them around to August delivery customers as soon as we can. I've just grabbed three more tech savvy people to help me with testing/rating the boards, so that we can get them in the shipping line quicker.
Dave
I see. So bitfurystrikesback.com/megabigpower.com bought chips from https://metabank.ru/asic and created your own board, right? /Valentin Not quite. AFAIK Bitfury is designer, and he sold some chips to metabank on the beginning of development process. Dave and Niko are not affiliated with metabank. |

Bitfury Chips were delayed From August 2013 to late October 2013 delivery. Is it Another Avalon in the Making? I am sure even late October will not guarantee they will deliver. All the newbie get suck into all the sweat talk in their group buys. Never Never join any group buy. Beware they are part and parcel of every unethical scams.
eve -> ignore list for stupidity... |

You have to remember that BFL is run by people who know how to lie and scam. If they smell big trouble coming, they will (probably) defraud all the money, and close the business. There will be absolutely NO refunds and NO hardware.
Disclaimer: I have many thousand dollars in undelivered 2012 order, and I am also pissed. But I do not see any good way out for the moment...

Why - tell me why - did I sign up for the cointerra email when thegenesisblock breaks the story on their offering? Nothing updated on the cointerrra site yet. http://thegenesisblock.com/cointerra-announces-2ths-asic-bitcoin-miner-for-15750/Also, while I am at it.... what a wasted opportunity to establish market leadership - they simply matched the price of BFL on a / GH basis. Barely breaks even based on the recent rate of increase in difficulty if they actually deliver in December. http://mining.thegenesisblock.com/a/6f382061faInput your own difficulty rate increase assumption if you don't agree with 75% per month Wow. I am very underwhelmed. You have to realize that Cointerra got into this as blind as customers of other ASIC vendors. Cointerra couldn't predict Hashfast nor KNC nor Bitfury, etc., etc. Matching price is a necessity forced on them that is also a big bummer for them. They were likely hoping on a price at least 3 times that amount. You figure the cost of this custom hardware after NRE probably comes down to a few hundreds of dollars. There was major major major money to be made, and Avalon proved it charging $7k for some ASIC hardware that was otherwise inexpensive to make. Avalon probably made 500% or more on each unit, who knows. Huge profit margins draw competitors. They've arrived now. But they're not able to charge what they were hoping they'd be able to charge. They're just as aced out as the people who bought miners looking at what they could've generated months ago (like Avalons were 15 bitcoin a day back in april). Price competition has not only hit, it's going to scare off other competitors. The value of hardware is going to crash so quickly after september that it's likely that many people formerly planning to startup an ASIC venture have now tossed those plans entirely, too much competition. And now people are worried that Nov/Dec asics might not ROI at all. Mining should always return to the point where the cost of electricity is just under the cost of mining bitcoin, long term. If I were an ASIC company wanting to stay in this biz long term rather than going for the homerun, facing all these fence-swingers right now, I'd be making incredibly high efficiency ASICs, air cooled, and plan to sell them for a slight markup and make up the difference on volume. A 10gh USB stick for $20 would be a market winner, even as the large asics begin dying like flies at the end of this year. You got some good points here. I expect that few of ASIC manufacturers that hoped to earn a lot of cash on "selling shovels" will start to mine instead of selling anything to the public. It will be their (desperate) attempt to recover NRE costs. They could build dedicated facilities in somewhere where electricity is dirt cheap and put all small-time-miners out of business thanks to economic of scale (28nm silicon cost should be around 1-2$/GH excluding NRE). Centralization of Bitcoin mining might happen sooner than anyone could have expected... |

I bet this will be another fraud
They DID already deliver. And you DID NOT do your homework before writing. |

Oh okay I see. What about the PCI express ports? Will the mining be faster in the ports that have 3.0? How many cards can I use on that mobo?
There is no difference in mining speed for using 3.0 ports instead of 2.0. I hope you know that mining BTC with GPU is not profitable anymore, it is barely profitable to mine scrypt coins (LTC) nowadays. |

If you are looking for PSU to power up the Full Kit, you should consider using Server PSU's. They are dirt cheap and rock solid :-) Here is good guide how to use them as an 12V power source: http://www.rcgroups.com/forums/showthread.php?t=1292514It is the path I will take for my 400GH kits. |

@Equate: Some cards are on riser (not powered risers), and some are connected directly into the mainboard.
3rd slot card was tested both ways, but it does not change temp readings.
@rascal777: I have tried manually changing Fan speed to 100%, it does not help.
Today I have used IR thermometer, just in case only readings in GPU-Z and cgminer are wrong, but they are not...

Maybe you meant June 24, 2012 and 23 almost done now. Its "almost done" for a month now :-) |

In Poland cheapest prepaid sim is ~1EUR, and it is able to answer calls for 6 or 12 months (but not sending sms or calling). Than you have to load it with cash (~5 EUR).
You can use 1 per 3 1500 PSUs. You will just reset all of them at once. Probably downtime will be less costly than buying more control units.

Does your 3rd slot have bad airflow?
Same as other slots. Today I have tried different PSU, nothing changed. |

Maybe you should look at something like those: http://www.ebay.com/bhp/gsm-power-socketYou just send text SMS message and it reboots. It usually handles 16A/250V. I have seen similar units for around 25-40 Euro. Maybe you should just ask your energy provider for more Amps in your home? It might be far cheaper than collocation with all those peripherals. New electric line able to provide 36kW costs ~1700 Euro in Poland. |

Why it is strange to you all that he only wants to trade with reputable members?
If he sends working unit, and scammer that gets it starts arguing that he only got one brick and two potatos, he will not see his escrow money for a very long time.

Third party holding your money until you confirm that goods you bought are in working condition. Then third party sends money to seller.
