Yea, I bought a 2 BTC guy to test it out... what's a couple BTCs anyways?  I will let you know when I don't receive it so we can put the nail in the coffin on this guy I guess....   Serious, you sent 2 BTC for a 5 GH/s unit Well you should get it in couple days then... they ship within 24 hours... YEs within 24 hours we will know its a scam 100% |

Well I bid 0.105 for 50 chips and if there are 50 left then I am back in

I think you are a little low.
Things you did not consider:
PCB price to design, build and mass produce.
Fabrication cost of device (assembly, attach heat sink/case)
Fabrication of heat sink and case
Cost to print pretty logo on case
Here is my best guess:
ASIC chip: $7
Other chips: $4
PCB/USB Plug: $3
Case/Heatsink $3
Assembly $2
Packaging $1
Total price $20 out the door.
Many knuckleheads on this website and Ebay paid (and are still paying) $230 USD (1000%+ markup) on this item
What is even funnier is at $20 a stick the people making these are sticking them in USB hubs at $20 a pop and mining 50-100Gh for about $60 a GH which is pretty reasonable for delivery today.
Disagree their chip isn't new enough tech to demand such a high price especially after NRE has long since been covered. They are paying a lot less than $7 for 300mh/s. Fair enough, then it may be $17 out the door. |

Well considering the news that has come to light regarding extra GH with overclocking if we could at least firm up the size of the PCB (i.e. leave it at 10x10) and get some measurements, then perhaps some water cooling solutions could be started.
What is on the back side of the Klondike board? Anything besides the thermal via pads?
Anyone have a picture?
Anyone have a measurement?

This can't be serious. US$3850 for a product anyone can get within a few months if they order today. I would bet an 8Gh/s Jalapeno at that price wouldn't ever pay for itself either when rising difficulty is considered.
So you think someone who orders today could get their Jalapeno in a few months? How many is a few? |

Ok let me know when its official

Can't use 39, needed 48, I am out.

When there is real news you will hear it.
Posting stuff like this is not doing anyone any good.
Bottom line is when BFL is shipping 400-600 units out the door a day they will be crowing about it.
Until then, just assume nothing has changed.

We will have a large Technical announcement coming next week. Where we will give even more accurate Power figures and GH/s. It will be a significant announcement which I hope will make all of our customers happy. and no before you ask I wont reveal any details before that newsletter goes out  Waiting to hear, when does the newsletter go out? |

$28 a piece??!?! Not going to get any suckers at that price
|
|

Please let's get a standardized working design based on components that are readily available and screw with it after that is complete.

Well I am going to assume I won my chips since no one is saying

TerraHash should not have any problems putting 16 ASIC on the board and meeting their hash rate that was specified.
The problem comes when someone wants to over clock the board and finds that overclocking is limited by the power supply.
I don't think TerraHash guaranteed that their board could be overclocked.
All TH has to do to make me happy is deliver the Hash rate I paid for 2 weeks after they get the chips. Anything more than that, makes them heros. |

I dont understand why cloud hashing had to be refunded. I mean the batch was bought already. How can they expect that the money can flow back? Or did terrahash sign a contract that allowed this?
Anyway... its poor morale of cloud hashing to act this way.
Cloudhashing is a business, a business that has overhead, which includes employees, electricity, data center etc so its not as easy as setting up a rig in your house. That business model is also tied to difficulty of mining etc. so the delivery of equipment by a certain date is critical to success. I am just speculating that Terrahash could have salvaged that deal had they agreed to reduce their profit margin. Then they would have made a little less money but also been able to advertise they were supplying Cloudhashing. Frankly, on another topic they would have been better served to advertise that they had the relationship with CH as this would have given them a ton of credibility. ASIC mining companies (all of them) suffer from the lack of marketing expertise. |

Unfortunately when I started the design I hadn't heard anything about over clocking Avalons and didn't design that in. I added some head room on the power supply just out of safety. I'm not aware of any higher current easy to swap regulator solution so the 3 options I see are:
1. Just place 14 chips / board. The wasted 2 chip board space isn't much of a loss.
2. Scrub the extra power connector behind the PCIe and add a IR3897 9A reg there to supply 4 of the end chips. This would cost a bit extra for parts - rough guess, about $5 maybe.
3. As #2 but extend the board by about 2cm and add 4 more chips, plus a full 16A IR3895 reg behind the PCIe conn. This would supply 6 chips, with 2 of those taken from current 16, making a 20 chip board. This would cost only a bit more than #2 due to higher board cost and the parts being a bit more costly, rough guess, about $8 maybe, but a more radical design change due to heat sink size also being different.
Another data point - the IR3895 over current protection kicks in at 18A minimum, so how well it behaves at max load probably depends a lot on how well it's cooled. Also, some of the reported power use in the other thread is for control board, 3.3V supply and fans so it could be somewhat less for actual ASIC power.
What would be the (estimated) hash rate of those 3 options? I think Option #3 is probably too radical especially if folks like Terrahash have cases being built |

Fantastic work Bkk, I as the rest of the community really appreciate the great work you are doing. And BTW, it does feel like opening a Xmas present reading your progress updated, along with the other great contributors to the project.
Cheers
