I guess we're having problems?  Anyone else get this as well? Any infos? Need to access my wallet urgently  |

I meant this in a good way  It should use LESS power that original 400W. You are my man. Awesome  |

Update:
I still believe we will be shipping everything as promised, apart from possibly exceeding specs by 25% on the power consumption side.
Is the hardware still capable of this? Any problems that come along with that (except for a higher electricity bill of course)? I'm also working together with Foofighter to produce casings for these units, ie. boxes with fans I have doubts we will have them available in time for August shipments though Will they come for free for orders that timely make it, like october orders? So the ones who ordered in august will only get the basic kit (without housing, fans), they are just unlucky, correct? (Nothing wrong with that) Thanks for those updates, it is most appreciated! Until now you are doing a lot better than your competition. Please don't rest on your laurels just yet  |

How in the world will HashFast or Cointerra or even BitFury's October delivery ever be profitable?
they were cheap. You had to expect a huge rise in difficulty, if you didn't, frankly: your fault. |

The proto rig is rock-solid after 24 hours of running at the new chip.conf.
These asics are curious critters - if you have a bad chip on a board, software will disable the chip in config. This causes adjacent chips to see a little more power and therefore get a slight overclock. For example most chips are producing around 1.5 - 1.6 GH/s actual nonces. But some chips are at 2.1 GH/s. In this way, even with some duds the full rig is producing 410 - 415GH/s actual accepted shares. Even Slush stats have caught up and show average hashrate over 400G at the pool.
I think this is unique - it seems most mining hardware is rated at a certain hashpower, but true output is typically less than promised.
Any chance you can post a CGMiner (or whichever miner you are using) screenshot of a 400gH/s product in action ? Genuinely curious, and excited with this product offering. Also, as I understand it, the products becoming available will be allocated to your 100TH endeavor first ? Does this mean that August orders will not ship until you have all 100TH online for yourself, or will the products be divided between customers and your mine if it looks like production delays may prevent your initial 100TH allocation arriving on schedule ? Cheers. I posted this video a few pages back of the screen output from our rig: http://youtu.be/naW5uGHLbZE - added it to the OP. The order for 100TH and August product is all one batch, and its being produced now. The first 4 full rigs shipped to Tytus today. I expect the rest to finish assembly very soon (though specific finish date has not been provided by factory). We have no reason to expect production delays at this point, or that we won't have enough product. Logistically there two challenges for each effort: For 100TH, assembling, configuring and running all those rigs will take time. We are trying to cut down on that by: preassembling racks, prewiring them with PDU, switch, patch cords, power cords & power supplies. We are pre-imaging SD cards for all the rPIs for both 100TH and customer orders. I have all the racks, PDU's, switches, PSUs, patch cords, power cords, SD cards, rPi's and a 16x SD duplicator all in hand. For August orders the main bottleneck will be testing for bad cards. We will try to fire up as many as we can to test simultaneously. We can see fairly immediately if there is a card with bad chips, so hopefully we don't need to test for very long - maybe only a few hours, or until the unit shows it can come up to operating temperature with no bad behavior. Then out the door they should go. I have two different ship teams and a build team for 100TH. Dave, I feel stupid for asking this, but I didnt read elsewhere: You, dave, set up the 100TH-mine? Or are we talking about something different here? Would you mind commenting on when EU-people that ordered a starterkit will get their units compared to US orders? Please give me some insight |

I already replied, asking for 100k+ chips and see if thats possible. The answer should be interesting, I guess. I'll ask about proof as well as the date since they have them ready.
Lol, that's a good one, 100k might be a bit large for them, my jaw will drop if it's not. it's not going to drop Dear Daniel,
I'm so happy that received your reply!
The first time, we just can supply 5Kpcs for you. After 5Kpcs, we will strive for order more quantities for your parties.
By the way, If you ready to place the order now, the price will lower.
I sincerely hope that we can cooperation by this business.
Awaiting for your early reply!
Best regards,
Michella |

So I wrote this alibaba reseller, this is what they responded: Dear Daniel,
Thank you for your inquiry!
We have sell Avalon chips, the best price is 19.7$/pcs. Now we can confirm arrive chips time, about 18th Aug. date, It's hot sell in the MKT, Do you need place the order now? When I get your news, I will order for you soon.
I'm looking forward to building a long term friendly business realtionship with you!
Awaiting for your early reply!
Best regards,
Michella I'll just leave this here.. Ask Michella how long she's been selling them for as you understand they are not available yet? Can she be trusted? Get her to verify this in order to gain trust. Ask for a picture of a chip with today's newspaper. You'll probably get a very clear and specific answer as to how long she has been in possession of said items... I already replied, asking for 100k+ chips and see if thats possible. The answer should be interesting, I guess. I'll ask about proof as well as the date since they have them ready. |

Hi!!! The exit has the same principle as the rear of a rocket engine - for a moment let's forget the fans and think only in passive air circulation. Since the hot air expands, it will hit the walls. But those walls angle will make it go out, instead of returning. Since the air exits, it will create a very low pressure in the middle, pushing the air from the back. Oh, now I get it. I should do more testing  . Btw, I ordered some temperature sensors (two), only need something to heat in the middle section. Should be fun I'm thinking about using a big-ass-fan this http://www.amazon.com/Lasko-3733-20-Fan-Box/dp/B00002ND67/ref=sr_1_1?ie=UTF8&qid=1376038212&sr=8-1&keywords=boxed+fanbut I can't find the equivalent of a boxed fan here in germany, only round ones (I want a boxed one!) |

thanks! Those are actually not that good, 4 times a 120mm fan would get me like 400m³/h, with a cheap Arctic Cooling F12. The reason I used those fans were I got them off ebay pretty cheap (like 1-2€ each). I plan on using nine of these:  Fan size: 92mm 55CFM, 32dBa, 3000rpm. Those should push some serious air I hope. Anymore thoughts? Could anyone explain me why I need the exit (the left side) and not just leave it open after flowing throug hmy to be cooled units? http://img.gawkerassets.com/img/18adxj7fzzmaxjpg/k-bigpic.jpg |

to get back to that sweet idea, I build a small setup with 4 fans, sadly different in power, speed etc here you can see the fans https://i.imgur.com/Qji5V1p.jpgthe upper left is really powerful, alot more than the others built this https://i.imgur.com/jmr1ZcO.jpgfired it up https://i.imgur.com/jTWBUcy.jpgwhat can I say: it works, but the setup is not good for comparison. The entry is 24x24 cm² and the exit is 8x8cm². A1*c1 = A2*c2 -> c2 = A1/A2*c1 = 9*c1. So one would expect the air to flow 9 times as fast as it does at the entry. It doesn't, its actually kinda lame. The powerful fan just pushed the air right out of the weakest of my fans (yeah, who would have thought that?  ). I think when letting the fans suck the air out I would not get that effect of air moving the wrong direction, or maybe not that bad. Maybe I should try this with just one fan, doing the same in a smaller scale or get 4 equal fans. Any thoughts? Yay!!! You made it!!! I'll PM you, but shouldn't the output be larger than the input (the other way around?)? And where is it pointing to? finally a prototype The fans are pointing in the direction of the tunnel (pushing air in), fixed my post |

Edit: The fans are pushing the air into the narrowing tunnel, so the output is the small end. I didnt make the middle (constant) section nor the output (widening) part, I thought this would not make a difference or have a positive effect. I might be wrong |

the "i'm not dead thread."
Just got off the plane, expect lots of news tomorrow.
The news is... He just got back from China and we will soon see 50 Alibaba Companies offering knockoffs for $5.55 at first I was like lol, but then this: http://www.alibaba.com/product-gs/994289436/Avalon_chip_A3256_Q48_avalon_asic.htmlthis is srsly disturbing me now. Why? Scam? 28-30$ a piece is a pretty shitty price, but in my world it makes perfect sense for a big-fish buying chips before everyone else und reselling them.. |

all you spineless people posting "good to hear form you, yifu" or "I'm glad you are alive, yifu :* " should stop licking his ass, get some balls, he's not treating you anyway better now. If those news aren't good news I'm in to pay a bad-ass-lawyer that rips his ass. PM me.

the "i'm not dead thread." Just got off the plane, expect lots of news tomorrow. I was busy  Better get some good news or people will form a mob with forks and fire and punch you in the face at the next bitcoin conference, no matter how well you do until then (what would be a fucking miracle!). I think you would clearly desserve to get your ass kicked. |

BS  IF.. if it's true; then Yifu Trollol should have amended his "NO BS" policy on the chip order page to include the extra time it would take to get chips made. Unless you believe someone talented enough to design an ASIC chip for SHA-256 and wanting to produce his own brand tablet can't compute "X" number of chips ordered * TSMC production = "Y" time for delivery. we're getting a little offtopic, but if you believe no more chips were received because.. yeah, why? Heres why I think no more chips were received: ordering was going pretty well, before or right in that process a big investor came across and told yifu "hey man, how about 14/X million dollar?" and yifu is like "Yeah, go ahead and order some chips" but he insist "no, that way I would need to wait before anyone else gets his/her chips, thats too long, put me in front or somehwhere at the top" - we can't do that, I'm all ethical. "Ok, I'll take my 14/X million dollar elsewhere" - okay, wait a minute, I was joking, you know they call me goofie fukyu? Trolled. |

Great work burnin. One question for you.
I paid in advance for more then 30 boards. If my avalon chips dont show up really soon, I will have to ask for a full refund from you.
What is your refund policy?
Thats just what I liked to ask as well. I don't think it's fair on burnin nor does he desserve this, but this is getting into a desaster and I cannot afford this if things will stay this way. There is just no sense in buying bitburners for quite some money if your chips will suck at a difficulty that simply kills any possible ROI ever. Fuck that "goofie fukyu" |

Article tl;dr
This was just the prototype, noone received any preordered bitfury asic so far

The other two fans are compensating for the one pointing directly at the cables. Freaking whirlwind in there. Those screw holes may actually help with pressure release.
That's the reverse of what pressure does. You want massive pressure inside, that's what fans are doing. I disagree to a certain degree. You don't get massive pressure from fans, thats not what they do. They move air. Did you look up what pressure a "normal fan" gets you? http://www.corsair.com/de/cpu-cooling-kits/air-series-fans/air-series-sp120-high-performance-edition-high-static-pressure-120mm-fan.html this has 3.1 mm/H20 which equals to around 30 Pa. If ambient is 1 bar, this will put another 0,0003 bar on top of that (I don't use psi, but you can convert it I easily). So 0.03% increase in pressure is not what they do, they move air like i said. No offense, just wanted to state this (correct me please if I'm wrong in someway) |
