Do some of them stop hashing and then do you have to manually restart them (unplugging power and/or USB)? How often?
The CM1s have very sensitive on USB. By discarding USB cables on any boards that drop out, and using good, powered USB hubs, I have reduced the drop out incidents to ~1-2x per week on the 140 odd boards that I have. I will ship these units with the known good USB cables they are running on now. Thanks. |

8 btc for all
the bids are per board, so you have been out bid long ago. |

Buy a gold model for power efficiency. And buy one rated at least 25% over your expected demand. Both efficiency and reliability drop as you get closer to the rated power of the PSU.
And if you are tempted by a cheap one, make sure to buy a spare.

I have purchased on slot in next weeks ad round for an ad warning newbs about BFL. I am looking for suggestions on content, and formatting.
My first thought is the following text:
WARNING: Butterfly Labs has a long history of failing to deliver as promised. Paying for their incomplete ASIC could be a huge money loser.
Anybody know some HTML to make that pretty?
Any other suggestions?
Coins sent to 1LuyJib375mAcyQLBJtT9sMNoQzKp2jcSx will be used to bid on future ad slots.

As of March 24, 2013, he was still going by mumu: http://webcache.googleusercontent.com/search?q=cache:9QhMRITN8ZsJ:https://bitcointalk.org/index.php%3Ftopic%3D155345.320+&cd=12&hl=en&ct=clnk&gl=usRe: The latest Avalon announcement in China(Translated). Batch #3, price and more.
Today at 07:23:29 AM
#321
There is too high probability that by the time Avalon batch 3 delivered BFL will be out in full 655TH force and then good luck with making back your 88 BTC
I have calculated that BFL pumping @25% of their ability i.e. 200 units a day * 22 workdays a month of 60GH units will increase network by 8.8TH a day
200*22*60/30=8,800GH
Not counting existing miners or other companies. So in 365 days you will make 43.71 BTC and deduct $1,314 for power (0.600kW*24H*365D*$0.25)
Price is 3-4 times too high so it's too big of a gamble. Feels like Avalon is cashing-out out of the game. Last final sale for all the marbles, grabbing with both hands. They pretty much dead very soon. Even if BFL will delay again for 2 month, Avalon doesn't have much better track record of delivering in volume. Where are 1st batch 300 and 2nd 600, I ask you?
And we are only 2 weeks away from their announced delivery.
Plus no warranty or guaranteed support. Sounds like they don't have faith in their ability to fix it, (or make it) And he was quoted: https://bitcointalk.org/index.php?topic=155345.msg1666637#msg1666637Also: This is ridiculous, normal forums have section names something like "Forum Rules" that is accessible from main forum page where there usually explanation of newbie limits. I had to go to another forum and ask them why I can't find a new post button.
Try reading things before agreeing to them...  BFL sockpuppet trying to draw attention away from Avalon who has held 90% of the top posts the past couple weeks? |

To show that's they are the same person and that a change of name occurred with no record, and now GalaxyASIC is positioning himself to sell 20nm ASIC chip-based mining rigs come this fall.
Which means that someone with administrator privileges on this board is aiding them in a fashion that is abnormal for the policies of the site. |

I am seeking enough Bitfloor debt to make pursuing action against Bitfloor and Roman worthwhile. Please see this thread. https://bitcointalk.org/index.php?topic=159221.0Mods, I hope you will tolerate the cross post since miners are the most likely to have been burned by Bitfloor and may not monitor the service forum. |

This is much worse than I thought. If they started shipping today, I doubt that orders placed yesterday would be fulfilled before October. Every post and ad on this forum should include this disclaimer: "Warning: BFL has NEVER delivered to a customer on the date they promised when they took their customer's money. It is reasonable to assume they never will." hmm.... what is the current bid for ad space here? Anybody willing to help me buy an ad slot? EDIT: Bid 10BTC for 1 ad slot. If you want to chip in I will use it to bid higher. PM me. Note that I will only use further Bitcoin pledged for this ad to either a) Force Josh to bid higher for all ad slots to bump the ad or b) make a bid in the next round for the same ad. Anyone who can make a nice HTML format for the ad, or improve the text is welcome to do so! |

They have accepted, and continue to accept an unlimited number of pre-orders. To the tune of 10s of millions of dollars I expect.
It is one thing to take a limited number of pre-orders to help with non-recurring engineering costs. If that is done, and you are honest with those early customers about the risks of failure and the consequences to them if you are unsuccessful it could be a reasonable risk sharing mechanism. Taking an unlimited amount of money in advance is profoundly suspicious. If they never deliver will Josh refund the salary and business expenses he has collected from unwitting dupes?
Continuing to take orders now, after failing to meet dozens of milestones, without disclosing the size of the order backlog, without any forecast of time to delivery from payment is simply wrong.
Even if the whole thing isn't an intentional scam, it has become one now. One more round of Avalon deliveries and BFL investors are unlikely to ever recover what they paid in BTC.

WTF!
What moderator changed this guy's nick to GalaxyASIC? Tolerating scammers is one thing. Actively helping them is ridiculous.

I have decided it is very unhealthy for the Bitcoin community to allow failures to continue operating. In my opinion Roman is a scammer for operating an exchange and holding both bitcoin and US currency for customers when his company is insolvent. Zombie banks are bad enough in the fiat world. We are fools if we allow such things in Bitcoin. Since I know he will not be tagged in this forum, I am considering taking action in the real world. Please see the link below if you are one of Roman's victims. https://bitcointalk.org/index.php?topic=159221.0 |

As many of you know, I have been bitching about Roman's decision to seize bitcoin from his customers at Bitfloor for a long time. Roman continues to refuse to show any plan that would result in his involuntary creditors being reimbursed in this decade. I am considering legal action, but would need to hold more debt in order to make such action worth my time. This post is seeking holders of Bitfloor obligations that would like to transfer those obligations to me. I am offering 2 possible payments: - A flat 0.05 BTC per 1.0 BTC of current Bitfloor debt
- Payment of 0.01 BTC per 1.0 BTC of Bitfloor debt, plus 20% of any funds recovered from Roman and Bitfloor less expenses for the recovery.
You will have to provide absolute proof of ownership of any debt, and sign legal documents attesting to both your ownership of the account and transferring control of the debts to me. If you are interested, please PM me with the subject BITFLOOR, and give this thread a bump. |

Shipping is flat for any number of boards.
The reserve price is 3 BTC.
Escrow fees should be paid by the buyer. I recommend 0.1 BTC / board

I have put 6 quad spartan-6 CM1 boards that underperform the 760 MH/s specification up for auction here: https://bitcointalk.org/index.php?topic=159052.0The reserve bid is 3 BTC, which is a bargain compared to the 2 spartan-6 X6500s which have been selling for 5.3 BTC |

I have 6 Cairnsmore boards that hash, but not up to standard.
Two of the boards kick out 50% hardware errors, resulting in an effective hashrate of ~400 MH/s
3 boards have one pair operating below standard for hash rates ~600 MH/s
1 board was programmed with 170 MH/s bitstreams, so it is running at ~680 MH/s
All of these are less than one year old, so the Enterpoint warranty should apply. I don't have the time to chase returns so I haven't pursued that option. It is also possible that re-programming the boards with HashVoodo, or Makomk's faster bitstreams with give you substantially better results. I haven't had the time to try.
All boards are up for Auction sale. When the auction closes I will ship the boards from best to worst in order of the highest bids.
Terms of Sale
Payment in BTC only
Escrow with John K.
Orders of 2 or more will ship stacked for side cooling and include up/down cables
Buyer pays shipping 0.3 BTC within USA, cost plus 0.1 BTC international
Auction Closes Sunday at 12 PM Eastern time Escrow payment due within 24 hours, shipping will be ASAP from confirmation of escrow payment

There is a galaxy of difference between getting wafer starts on a 10 year old Fab and getting access to current generation process tech. If you aren't spending hundreds of millions with a foundry, they aren't going to even talk to you in the first couple years of operations.
Really, How then was Adapteva able to get their 28nm Epiphany IV platform printed and packaged in less than 6 months? Scam too, right? Not really much difference between a 800,000$ kickstarter project and a bitcoin project. Learn to read. Then learn to comprehend. How long have 28 nm lines been running in the foundries? Hoping and wishing for unicorns won't produce unicorns. It will just make you old, fat and stupid. |

If you think TSMC is going to give any attention to Bitcoin ASICs when they have the likes of Intel, Apple and nVidia to deal with... well, I wish you best of luck  Who do you think is making Avalon chips? I guess all of those people with avalons are a scam eh? There is a galaxy of difference between getting wafer starts on a 10 year old Fab and getting access to current generation process tech. If you aren't spending hundreds of millions with a foundry, they aren't going to even talk to you in the first couple years of operations. |
