If we are playing show and tell  How did this happen? I thought the heat sink on the other side was big enough to absorb all the heat? The miner was running fine for hours just doing it's thing. I went to bed and when I woke up it it looked like that with the copper sink hanging on for dear life off the bottom of the tape. I bought some extra fans , has one blowing cool air in and and another exhausting the hot air out. So I ran to my computer and check the putty log and it was just popping up with an error over and over. SoI killed it and switched off the device and haven't mined since,even with the now one good card I have. I'm not looking for a fire, but at least I have renters insurance if it went up. Hell probably would have had my money back from the mier now if it would have gone up. The thermal tape was just inadequate for the job. Nevertheless, it is interesting that the heat sink on the otherside could not absorb the heat. So even if option #1 was working, it would still be a fire hazard. The big sinks on the other side were drawing lots of heat, but obviously the design was inadequate. I figured I'd pull out my Nikon DSLR to capture as much of the detail as possible. Obviously that was not necessary with the twisted wreckage you received. |

I still have the question....What is the timeline for the technobit solution? |

And I really want to know who they got making option one and if it's the same design as this one.
And for three I'd really like to know, how much control I'd have over my set up. And obviously the all important price for electricity.

The timeline would be around 2 weeks if you can get your A1 chips to Technobit.eu to have it assembled by them. I've got zero confidence that AMT has the personnel to actually deliver anything on schedule. Let's just list the 'little' things they forgot to do: (1) Forgot to put adequate padding on the shipment. (2) Forgot to include a backplane. (3) Forgot to ship a missing backplane. (4) Forgot to include basic instructions to wire up the system. (5) Forgot to accept a returned package (3) times. That's just the logistics part of shipping a supposedly working unit. How about the assembly part. (1) Forgot to test the system prior to shipping. (2) Forgot to apply thermal paste properly. (3) Used the smallest possible heatshink (4) Forgot to align the boards so that the backplane could fit. (5) Never figured out how to provide enough power for 1.2 THs boards. BTW... where is that backplane that was supposed to power 6 boards... I guess it never existed.. in short AMT never had a chance of delivering a 1.2 THs system. To conclude, despite the best efforts of AMT to come up with something... a 1.2 TH/S that was advertised never existed! No proof of a working system. No proof of a 6 board system. |

I will agree to a refund in BTC, at the price of BTC now, equal to cover the price I payed of $6060.00 USD for the single unit I ordered.
$6060.00 / ($440/BTC) = 13.77272727 BTC.
If I accepted #1, it needs a PSU to come with it... or it needs to be split into 2-units with 2-backplanes, 2-RasPi's and daughterboard, 2-LCDs, with the 6-cards total (3x and 3x), 2-cages and no towers. This, so I can buy two separate 750W-800W PSU's, as I would not pay additional $350-$580 for a 1500W-1600W PSU, which may not even have enough power.
Same if I accepted the technobit solution. I would still expect the same 1.2THs, 6-card setup, with the provisions to operate them as two separate units. This, again because of the power supply issue.
If no PSU is being provided (as you stated), and no tower-case (requested in my case)... I would think that the extra backplane, RasPi and daughterboard, and LCD screen, would be a fair replacement for the missing PSU and Case. (Oh, and all associated wires.)
As for the BTC or a cash "refund", if accepted... I could not wait another 6 months for that. That would have to be immediate.
Josh, I know you are in a tight spot, but that is the minimum I can personally spare to take as a loss myself. I tried to help, and did a little to those who asked in PM's. (As limited as my help was.) Wish I could have done more, but it seems that there is nothing I can do now. I am having to haggle for my property, which is actually disturbing me at this point. My compassion for you, and your situation, is still sincere. However, It is just a matter of business now.
Just for kicks and giggles, if accepted... Here is my BTC deposit address.
BTC refund: 1Ap9RcRb4qtTV5icioqfeT86Qj1eXFQ3Ez
Good points ISAWHIM, I as well would be needing extara backplane and at least the daughter boards for the pi for the 3 units I have on order. (the rasp. pi is cheap enough that I could supply my own for the 2nd units) and I as well could live without the cases if that helps at all. AMT, please consider this in your options. |

I thought they were just shipping out surplus on the old design for option 1? For my part I would not want that old design. The technobit seems to be more stable and is working from what people are indicating on their board. |

use something like this for a heat sink... How is the heat sink attached to the chip? There are some spring loaded screws that keeps the pressure constant. You can just put some sticky thermal tape on this. I've had CPUs fail simply because the thermal paste was not properly applied. Now imagine this AMT system that has to run at non-nominal speeds for 24 x 7 x 365. Man.... we are so screwed!!! |

Well if they just have us send the hardware striaght to technobit directly it sidesteps that whole situation altogether. But yea you make a point in the little things. |

Umm you do know you are looking at a motherboard with a heatsink resting on the CPU slot right? And its not even screwed in...its resting there. Its not a fully assembled board.....this is a PC not a miner....not sure if you are aware of that based on what you just said. |

I can't tell if its screwed or not, but the sheer weight of the thing should provide enough pressure between the heatsink and the chip. Yes, of course it is a PC. You think a miner requires a lesser quality heat sink? Look at the GPUs out there, those are also serious quality heat sinks. Look at the design of Cointerra, they got liquid cooled heat sinks. So what is it about a Coincraft A1 chip that it requires a lesser quality heat sink? You can't cheat physics here. CPUs and GPUs all are at 28nm and have speeds that are similar to this miner. All that electrons flowing at that speed creates the heat. All that computation creates the heat. |

It's screwed in, also I have it in a military style 10 PCI case + 4 GPUs which has the heatsink going sideways. The mounting is weird, but I believe screws may be coming from the bottom of the board. This heat sink is crazy high, and would never fit in a regular case.

GPU users go to great lengths to remove the stock heatsink and replace it with something more effective. The technobit and dragon boards both have the A1 chips clustered close together. All this discussion is moot now since AMT is like 2 months delayed and the competition is delivery goods that AMT can't match in price. |

Since I just proved that one of your statements was in error, the rest of your post must be fud. There's no evidence that this is even true. The 5 board miners that have been shipped are capable only of 1 THs. This is the same number of chips as the equivalent Bitmine system that is rates at 1 THs. There is no evidence of a 1.2 THs system that can accomodate 6 boards. In fact, there isn't even any evidence of a backplane that can accomodate 6 boards. So what did exactly did AMT sell to its customer when said product doesn't even exist? |

I have good news, and bad news. 6/10 of my cards are working, the other 4 don't even show up on a backplane. I never received the backplane they said they sent to me, and I am furious. Also, I made my first bitcoin in 2 weeks of mining! Yay!. Thanks to AMT for the delays and nonworking equipment, resulting in IMPOSSIBLE ROI, and frustrating customer/company relations.
