It would probably be wise for everyone that is upset with their damaged/non working miners - to go ahead and pack them up correctly and ship them back to AMT (at your expense). This way they can't fight giving you a refund.
Waiting for RMA parts from this circus known as AMT just doesn't seem worth it.
These miners have incompetence written all over them. Hard to believe anyone with technical skills would of been able to ship these out in this condition. QA my ass. Thermal paste, loose screws, missing cables, damaged boards and bent cases. Everything that could of possibly gone wrong, has - and now it's time for AMT to rectify this situation.
AMT you should be honoring refunds NOW. People have waited, and now they are FUCKED. Tell me how anyone WOULDN'T be eligible for a refund after you've mailed them busted hardware after months of delays?
I still believe these were intentionally packed poorly for insurance claims. These miners are probably riddled with heat/power issues, even when they aren't smashed in shipping. We just have to wait and see how long someone can run one of these at the full 1.2TH STABLE, without it burning out.

Again folks do not sign on delivery just refuse. The chance to get your money if there is still any chance not in court is bigger Ps Thermal paste is not an issue assuming it is non conductive But amt are full of surprises always  |

If they used a brand of thermal paste with silver in it, it might conduct VERY LITTLE electricity - not enough however to short something out. The silver stuff is usually more expensive, so I highly doubt AMT went with it. |

OK. Plugged in the HDMI and at first it did not work but did a power cycle with the HDMI plugged in and success. Now I have to pry open the damaged USB port and get a keyboard working.   |

I will definatley be packaging mine back up and shipping it off back to amt with a letter requesting a full refund. And i will seek advice here in the uk at the office of fair trading to see if they can help with this matter.

This is pic of 1 of my boards that doesnt run. you can see the bent copper heat sinks and paste all over.  I don't understand the heat sink configuration here though? Why are the heat-sinks on the A1 chips so small? What is the bigger heat sink on the other side connected to? Because 30 % of the heat can be disposed from one side of the chip 70% from the other This seems to be done right CONGRATS. AMT This is useless of course as all my other posts right? CPU and GPUs have their heat sinks on the side of the chip and there is a conduction path from chip thermal paste to heat sink. I don't understand this kind of a configuration, there is no conduction path from the chip through the board to the massive heat sinks. yeah there is. bitfury chips are the same type of package. there are thermal vias going through the pcb that dissipate most of the heat out the back . |

Hitting the IP address with my browser and I'm in. I've configured cgminer with a few addresses.
Next up, I will use a power supply and go one by one, blade by blade.

In the CPU space you can easily get failures if you don't put the right amount of thermal paste and have it securely attached using screws with springs. For something that is supposed to run 24 hours 7 days a week, these tiny heat sinks that are secured just using thermal paste doesn't look like it'll work. Every high end design like CPUs and GPUs have the heat sink attached from the top of the package and never via some conduction on the PCB as some other claim to work. |

There is a thick copper "Ground Plane" and the small holes are called "vias" the ASIC chips are designed to pass 80% of their heat (watt dissipation) thru the board to the large sink. CPU and GPU Dissipate thru the Tplate or Top Plate covering the silicon. Those tiny copper H/S are failsafe, and do 20% of the work. The Vias fill with solder when chips are mounted, completing the heat transfer part. |

I don't see any fasteners, the boards are positioned vertically so if you use certain kinds of thermal paste, the paste starts become liquid when heated, so what could happen is these heat sinks just fall off! That is why CPU have screws to fasten down heat sinks! You need constant pressure. |

OK, so I've secured the blades in the chassis with the screws I found in the bottom of the box. The new problem is now the pins do not line up.  With the screws loose/removed, adjust the backplane/boards to plug in, then see if the screw holes still line up. Cage may be bent akilter  ON SLI we always put the rigid connector before GPU hold down screws, allowing the backplane to align the boards. |

Moving on to the controller.
I've got it powered via the 5v USB. The pwr light does turn on.
I plug it into the router and all the lights come on.
I do an IP scan and receive the following list. I hit each IP address with the browser and get the following results.
192.168.0.1 - router
192.168.0.7 - No response
192.168.0.8 - No response
192.168.0.9 - No response
192.168.0.11 - printer
192.168.0.15 - No response
192.168.0.40 - Ant miner
When I unplug the controller, my list stays the same.
How do we get into this thing?
A few pages ago someone mentioned that you can hook up monitor to pi and see what is going on Just look for it Btw you could try ssh or telnet plug in your hdmi into the pi to get it do display you may have to power down and restart, tv should change to hdmi. than log in with u=root p=amt should than type killall cgminer wont display anything after just root address then type ifconfig and its the ip address that is 192.168.1.*** type that into your browser and bingo. to do it without going into the pi via hdmi download putty and put same adress |
