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.

Also likely the thermal grease on the other side was not very well applied either. Again real cut rate work to keep costs down. This is usually how some houses operate, AMT already made that much clear in this situation. But in either case we are paying the price. Seeing as they are now providing us with options...lets hope these options dont take us months of waiting again. I dont think I want to deal with that hassle. I still have the question....What is the timeline for the technobit solution?

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.

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.

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 hazzard.   

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 agree with this. At bare minimum I would only accept what I paid for which was 1.2Ths. if you can toss a bit extra for our troubles I would consider it a great plus at this point. For me option 2 seems like the most viable. Oh and

Probably the thermal tape was poorly applied, creating an air pocket that led to that. Usually the case from what I have seen. Considering the assembly quality in general and overall leakage of the thermal grease this is not a shock. It looked like a rushed job.

This is indeed problematic for a couple of reasons:

(1) There is no screw that ensures that the heat sink has some pressure against the chip.
(2) The orientation of the boards are such that the boards are vertical and therefore gravity isn't even going to work to keep the heat sinks in place.  

Also, I've been saying for a while now.  These heatsinks are too small.

Look at the designs of both Technobit and Dragon.  They've got massive heat sinks on the chip side and it's okay even if the chips are all bunched together.   Even the AMT system has a much larger heat sink than what we see here at AMT.

I can't understand the design.  These are 28nm chips running on full throttle, AMT however decides to put the smallest heat sink one can imagine!  

That would likely be more the fault of the SMD house IMO. That design decision is likely one of many reasons why they are in this mess int he first place.

At this point we would expect they will take back the obviously flawed miners we all have and exchange them for properly working hardware. I presume that is the whole point of the options they are offering. Which also means receiving hardware that is shipped back. Can AMT clarify a plan for that as well? Considering mrpark's experience it puts everyone else on a bit of worry and with good reason.

I also wonder if disconnecting the power, and the damage was a decoy to make me think the boards were damaged in shipping, when perhaps they were just non-working boards.

I can't prove any of this, but everyone may have different opinions on this.

Hard to prove that the damage was deliberate.

However, very easy to prove negligence.  The padding on my box was completely inadequate.  Anyone from FEDEX will attest to this.

Yes, the unplugging, they could just say "Ah, it happened in shipping".  The padding and the way they didn't even use a box in my case, (they just wrapped the miner in in cardboard and taped it!!!).  As far as proving things, that is usually not my job, its up to other people to decide based on the photos etc.
