I said last month I would have tons of 6990s for sale in May... Well here they are! - Cards in excellent condition, used for mining in datacenter-like environment (no dust, cool air)
- Come with full retail box + manual + video adapters + sales receipt for warranty
- Each 6990 mines at 691 Mh/s stock clock
- I have excellent reputation (check bitcoin-otc rating in my sig)
- I accept payments in USD or BTC
- I can ship anywhere in the world, from Los Angeles; buyer pays for shipping
I also have a single 5870 I would like to get rid off, never been used for mining. Sold!Email me at m.bevand at gmail.com, or reply to this post (no PMs please -- too inconvenient), and make me an offer: quantity you want, price, etc. |

Look at the horrible quality (not the image quality, the horrible design). Since when does the FBI release private information like this, much less in such a horrible design? This is a 12 year old's copypasta in Word.
The PDF file has been carefully anonymized: content has been sanitized (each page is an image, not text, hence the quality issue) and the file metadata has been stripped out. This was done extremely well, which would make sense given it seems to be leaked... I side with julz, psy, and others: it appears to be a real leak.

Yeah, anyone who can write a firmware for it to work  Yes, multiple people in this community are capable of designing (or have designed) a 400 Mh/s mining core on the EP3SL200, and I believe are capable of shrinking it to fit on the EP3SL150. |

Thanks for confirming, ngzhang. It is not too surprising of a discovery, as the Stratix III EP3SL150 was one of xaxik's reverse engineering guesses: https://bitcointalk.org/index.php?topic=53530.msg720365#msg720365The most surprising, for me, is to learn that used units of these FPGAs sell for $50-60 in China. Two chips per Singles, plus $50-80 for the remaining components, means that the BOM cost for a BFL Single (with used FPGAs) is ~$150-200. This means anyone with a chinese source of used FPGAs could manufacture BFL Single clones producing about 5 Mh/s per dollar(!), making it by far the most economical mining platform. |

The echo should be able to be easily removed with audio processing...

Finally some tough competition against the BFL Single! This $640 quad LX150 board would have about the same perf/dollar as the Single (1.33 vs. 1.39 Mh/s/$), but should have twice the Mh/Joule efficiency! And if you, Enterpoint, can truly deliver first prototypes by the end of May, you would beat the (currently) 10-week waiting period for Single orders. * mrb preorders... |

Man all you guys moaning about the noise these things make... damn. I decided to make a video just for you: https://vimeo.com/41028028I accidentally set the thing down on something that was sticking up, and it got caught in the fan and broke the blades off. So I decided to give it some real cooling.  I am laughing at the bits of wires that are being sucked into the new fan when turned on. Be careful, you already broke one |

if you collect enough condensation points, you get to bonus round.
Won't happen. Condensation happens when warm air meets a cold surface. But in the fridge, air is cold and the FPGA is warm. So it'll only happen directly above the FPGAs?  No. Think... |

With the massive amounts of money that are going into mining hardware right now, I wouldn't touch it with a 10-foot pole. If you do, BFL is the most profitable option by a wide margin.
Hard to believe the BTC community hasn't identified BFL's chips. Open solutions are stuck at poor profitability due to not being able to identify, IMO, what is a commodity chip. BFL's chip was identified. It is a Stratix III EP3SL200 or EP3SE260: https://bitcointalk.org/index.php?topic=53530.msg720365#msg720365 |

Any shot of getting 20 card package price ?
I will have 20 cards for sale, but next month, not now. I will buy 4 or 8 for a good price.
Currently I have more buyers than cards... 8 cards will definitely not be doable now, maybe 4 if some of the interested buyers flake out. I will let you know. |
|
|
|
You having much luck selling these? I am interested in purchasing a few....
I have sold a good chunk of them so far. And all are technically "pre-sold" (although there have been so many flaky buyers who don't show up or pay up at the last minute that I am sure you still have a chance to get some). How many do you want? You can also contact me privately if you desire so. |

offering 325 coins + ship for 4
310 coins + shipping for 3. That's equivalent to 1.4 Mhash/s/$... |
|
|
|
How much would international (UK) shipping be on these?
For 10 cards (heavy!) about 400 USD using UPS and ~1 week delivery time. |
|
|
|
I was just after getting off the phone with the organisers, the videos will be available on the TED website in about 2 weeks.
2 weeks have passed. Is the video available? |

More power for less hash compared to 5970s.
No, 6990s mine faster than 5970s. But they have a lower Mh/J. |
