Well if they are Dragon miner v1 boards, they weren't designed to run beyond 200GH so beware!  The Dragon Miner v2, which was designed to run at 250GH, has bigger heatsinks, different to those shown. Will get a psu now so maybe 1h or so if i fix it before work.
 looks nice! |

Those heatsinks seem a little short for 250GH @ 8x A1 chips per board. What temps and power at the wall are you getting? I'd be interested to buy them without a case and stack them with a big silent 120mm fans directly on the heatsink!  Any chance we can buy it in kit form minus the cost of case, fan, and labour? |

 Its after midday in the UK so it doesn't count Rubbish it's "All Fools' Day" not "Half Fools' Day".  |

Look what I got today ... anyone else get one? I blacked out my street address.  STATUS: Canceled did they return your £11.5k? |
|
|
|
And how do you do that?
I plug a spare PC fan on the red/black cable on a molex connector. Other options are to attach an old hard drive, floppy drive, CD/DVD drive etc. |

Give it some time to rest 2-3 min without power
Then see if chips will be back?
Not much but this is only thing i can suggest
I have tryed soon, i have replaced to a other FAN in the bottom. The heat sink was cold. If it has polyfuses (those brown tags that stick out) it might take more than few minutes I'd leave it unplugged overnight (some pop it in the fridge). http://en.wikipedia.org/wiki/Resettable_fuseYour power supply probably went into emergency shutdown too. That usually requires the paper clip to be removed to reset that. Some PSUs require something powered on the 5v line to stop them tripping into emergency mode. My ThermalTake 730W did. Marto never said what the orange LED means, but I suspect it's a polyfuse error, my Hex8A1 with 2 detached polyfuses has orange LED, but still mines. |

Miners were running on 490/1480. Wow you pushed it too far? Default is 350/1200, too many Gigawatts!  Might want to try adding a fan to the other side of the board if you're running them hot. The pieces of card are normal. I have them on my first Hex16B. I think they were there to stop some solder shorting on the heatsink. Did you remove the card before it blew up? |

Our new Enigma range of miners are as follows:
E1 - 750GH/s - $3565
E2 - 1500GH/s - $6750
E3 - 2250GH/s - $9565
E4 - 3000GH/s - $11999
All the above miners will be shipping on or before 31st March 2014 (Hopefully sooner!) Oh, I think I get it now... APRIL FOOLS!http://en.wikipedia.org/wiki/April_fools_day |

Just remember that secrets work both ways: how would you like it if someone said it was an 'open secret' that you're using asicminer chips? I think you owe the KNC people an apology.
What happened to your $1/GH miner Novello? Got a web site yet? ETA? Is it funded? Is it even real? https://bitcointalk.org/index.php?topic=416888.msg4522940#msg4522940If you're genuine and don't want to sell out to a VC consider www.crowdcube.com to raise your money and issue some shares. |

KnC flood the market everyday with 400000 dollar worth of BTC from their mining operation.
At this moment they get less than 400000 dollar, BTC price dropped.
Taiwan Semicondutor Manufaturing Company and other companies who sell parts to them only accept dollars.
Those bastards keep expanding their farm.
They're killing bitcoin. They need to be shut down. This is why I suggested ages ago that the Bitcoin protocol should have included a punishment to discourage centralization. Once the people lose the monetary printing press to an elite few, Bitcoin becomes no different from fiat, and you lose the community. If you want to teach them a lesson mine MaxCoin on a GPU instead. |

1st one came with 4 cards installed and ran Pretty cool didnt generate any heat and i could feel a good breeze on the other side of the hall
what i've noticed was that later batches ( and i'll be checking my 3rd order when it arrives) started coming with 3 cards installed instead of 4 and run a bit higher.. I think they dropped from 40 chips / 5 boards to 32 Chips / 4 boards. Yeah it's got to work 20% harder so more heat/fan noise. If they dropped to 3 cards, lol, that would be crazy! I think you made a mistake?  |

Trying to refund one Neptune. Will report how it goes. Is China trying to ban bitcoin every other day? Why not do it all at once? It is a bit funny, because twice already I made a small purchase and next day-China bans bitcoin!  China banned shit, just watch all the Bitcoins moving to China on www.fiatleak.comDon't even get me started on their one child policy that didn't even dent their population growth! China can out lie/cheat any other country!  |

Hello. I just picked up one of these: http://coinsfortech.com/shop/coincraft-1ths-28nm-asic-bitcoin-miner-with-power-supplyIt works very well right out of the box at the speed promised and I am already getting coins out of my pool after only 30 minutes. However it is LOUD! It is like having a hair dryer running. It is in my apartment and it is just unacceptable how loud it is. Does anyone have some advice on how I can solver this problem? Some sort of some proof cabinet or perhaps a quieter cooling system? Just a question which is not related to the noise: What hash rate do you get on different pools with this machine? Are you limited to BTCguild? This is why we advice people to just buy the coins! You'll have to put up with the heat and noise for 6 months just to get your investment back. Is it worth it? For most people, no! As for pools, BitMinter also works fine with my A1 chip based boards. You need a pool that supports 0 Diff (auto) or large Diff 512-1024. To get the noise/heat down you'll need to underclock to about 800GH and change the fans for quieter ones. (The 4 board 32 chips version is working 20% harder!) |

A1 chips need a high diff or a pool that supports 0 diff (auto).
I run my Hex8A1 (8x A1 chips) on BitMinter and BTCGuild.
I've also thought the new Dragon miner (4 boards x 8 chips) may be running too low voltage which would result in high hardware errors/rejects.

Does your machine have 5 boards? A 1000 Watt supply running at 1100 is pretty much giving it a very short lifespan if run 24/7. I noticed your cable is much heavier than mine, is it warm to the touch? I might replace the supply with something higher if they are indeed running that much above spec.
You can see from from the video it's the new 4x boards x 8 chips which run at more watts. More importantly what is the hardware error/reject rate like at 1130W? (282.5W per board) when I run my 8xA1 chips below 300W it's quite high! (but they are 1st batch A1 chips) |

2 BTC seems expensive for 260GH/s, the cost of 2 S1's (including shipping and VAT / customs to UK) running 400GH/s
You need to add 25% for VAT+Customs then add the cost of an extra power supply. UK electricity just rose to 15p(25c)/kWh! and the Ants will use 25% more power at 2W/GH. Not sure why Marto's A1's are not as efficient as the Chinese A1's claim to be though. Mine were 1.5W/GH @ 260GH and 1.2W/GH @ 215GH. It's not any better than my Hex16Bitfury miners really, but it will beat an Antminer!  |

What clock/volt where you trying to run them at, how old were they, just so the community can know where the overclock limit/life span is.
I've never tried above the default 540/900 because I've not seen much feedback on pushing the clocks.
I've had 6 running on 1800rpm quiet fans for 3 months now without issue.
Thanks for any info you can add to help us understand how it died.
