hey guys just done a little video of my 520gh miner, the video is not full screen like normal for some reason as i took it on my phone. im posting this as nobody else has posted a video of a working miner as of yet that im aware. full 24hr graph will be posted once ready for your scrutiny. https://www.youtube.com/watch?v=w7rUW2H-wqk Nice!. Hopefully I will soon be getting the same kit. Thinking about a Coolmaster 1,200w PSU but for now have a 1,200w HP server PSU coming tomorrow (much cheaper btw) to poke around with and figure out until my 520 comes in. Query: do I need any 4-pin Molex (+5 & +12v) for anything? The server PSU can feed 5v @3a if needed. On the temps: 65-70c on the chip sinks? Toasty but not unreasonable. For 'official' specs on the A1 chip I refer to Bitmine's Github site. https://github.com/bitmine-ch/bitmine/blob/master/Specs/CoinCraft%20A1.pdfp1 is the quickey specs, p. 13 is power and temp specs. What do the chokes on the board read? On my Ants they are the hottest things @ 75c in a slow/dead air zone, around 40-50 in an airstream. Chokes can easily take up to 140c or better but - caps sitting next to them are not so happy... Got a thermocouple to poke between the big heat sink fins opposite where the chips sit? Be interesting to know the ΔT between the sides... |

Yeah,
I just want this damned thing to work.
I got 2 cards working last night, and said fuck it. The backplane had to be plugged in WHILE powered up. After I unplugged, and plugged it back in, I restarted CGMINER and it worked with 3. I tried to get 4 working, but the damn thing is buggy as shit.
Any suggestions AMT? Are you actually going to send me my boards this week?

Did you see this post about power rails etc? Methinks it may address some of the problems folks have been having. https://bitcointalk.org/index.php?topic=304605.msg6204573#msg6204573Oh AMT, btw: when my kit arrives I do have any and all test gear you folks want us to have. Precision DMM's, IR and TC temp probes, oscilloscopes to monitor the power rails for spikes/dips, current probes, etc. You name it I have it. |

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.  As in the spacing for the boards and backplane are different? <facepalm> (this forum needs an emot for that...) Hate to say but after seeing that fried board earlier might be a good idea to re-torque the screws pulling the heatsinks to the asics to make sure they are tight. Always cross torque to balance the forces like working on an engine. Depending on what AMT uses for the heat xfr material (paste, silicon pads, etc) is possible for some creep to happen and considering how fast these are being built is safe bet that is not checked for... |

Or the screws *were * there and are now rolling around in the packaging or delivery truck. Don't suppose the screws have star-washers so they can't shake loose do they?
Found these under the flap at the bottom of the box.  Hopefully the blades banging each other during shipping didn't damage them too much. They need to be using something like these machine screws w/star-washers that are part of them http://www.mcmaster.com/#95345a047/=riqrv4 also available with sheet metal threads. |

NO miner is ever sent out without boards screwed in, period. This is ridiculous. Obviously it has happened. Or the screws *were * there and are now rolling around in the packaging or delivery truck. Don't suppose the screws have star-washers so they can't shake loose do they? |

AMT_MINERS, On the back plane coms - are these using hard wired usb?
IF they are, are the boards powering their usb circuit from the backplane?
Just shooting in the dark here...
Reason I'm asking is that a common problem with BFL's Jalapenos was from using underpowered USB hubs. You'd think the Jala side of the usb link would be like any other device but for some reason they draw near max/port usb 2.0 power which causes numerous weird problems...

weve been playing around with mine all day pretty much. i deffinatley need 2 new cards sending out. ive paid for 520ghs and im getting 250ghs. there are no more settings to try with the other 2 cards.
timmyd, have you tried simply leaving the 2 other cards in to simply "warm up". I know it sounds stupid, but worth a try. Good luck! Yes dude the other 2 boards will run for like 1 min. one gets upto 190ghs and the other 170ghs and then chip failures happen and the both eventually die off and shut down.  You're having voltage issues similar to James and Reggie, what power supply are you using? Perhaps you can address the issue I posted here earlier. I would appreciate it. It doesn't seem to be recognizing the cards at all and says no a-1 chip chain found. that is for every board. I posted t a few pages back. You or somone else mentioned about the backplane being seen as a 5-port usb hub. If it is and if that is how the coms are ran maybe the hub is dead or has no link to the Pi? |

Well if ya have verified that it is the cards and not the slot/power connection by trying them in the 1 working spot then ja I'd say an RMA is in order for them.

Tried swapping them 1 at a time into the slot where the 1 card works? I'd think should be able to run 1 at a time. just leave the other 2 out/disconnected. If they can all run alone then sumptin' else is up. |

On PuTTY, at the dottom of its window try clicking never close window to see if the info can be scrolled back after the session ends? |

The completed rigs should have been just repacked into their original antec boxes. And then packed into a separate larger box. That is Fedex's recommendation apparently. I still haven't gotten an answer regarding my miner or arrangement to go pick it up. I emailed as requested more than once just to insure someone got it. But no reply yet.
Hopefully over the weekend I hear something. I am trying to make arrangements to go get my hardware. Since it would be nice to have it intact. I prefer to go do a pickup than have to deal with the risk of it getting packaged badly and showing up damaged. Just more wasted time on dealing with that.
They did answer ya here in the forun https://bitcointalk.org/index.php?topic=304605.msg6179402#msg6179402 but ya still nee to give ya direct contact t follow up on that... |

Hmm. Since FedEx accepted the package then technically they should be responsible for the damage.
No. They have guidelines on how to pack a shipment. If those guidelines are not followed, they will not reimburse damages. See if you can find AMT's packing method in the guidelines: http://images.fedex.com/us/services/pdf/packaging/Computer_fxcom.pdfYep. The FedEx info looks exactly like what we do for our equipment... |

Works for me (3 higher than ^^). My now 1.1-1.25 TH/s Ant pharm (eating 2,496w) is tiding me over for now.
Wow, did I read that correctly? You 1.2TH is consuming 2500 watts? Yikes! yep. 6 Antminer S1's OC to 190GH/s, often peaking for a while @ 419w each, usually more around 390-400w each. Do gotta say that '190' is a low spec. Depending on what each are chewing on actually is more like 200-203 GHs, sometimes as much as 210, sometimes as low as 170, never all exactly the same. Still, more than paying for their feed several x over and on-target for my ROI. So folks, while AMT's A1 rigs may be hungrier than expected it is still a lot less than the current alternatives. |

Remember, if you do use 2 PSU's... you WILL need something on both PSU's to give the PSU a 5v load. Without something on the 5v rail, the 12v rail will not have a reff-voltage to stabilize correctly. EG, plug an old CD-Drive or Floppy-Drive or any other device into one of the standard MOLEX (four prong "oooo" cables.) For the AMT unit PSU, this would be the raspberrypi as the 5v load. For the other PSU, you will need another device. (Find a nice 5v LED-light display, and you have a cool load to light-up the cards.  ) P.S. An external 12v fan, will not work, as it does not use the 5v on the molex connections, though it may have a wire on the plug, it is not actually connected to anything. (It will say 12v on the fans sticker.) You know if you have power issues, because some boards will run at abnormal speeds. If you turn the unit off, and remove a board, and the remaining boards run normal... or better... then you are running into voltage issues. The PSU is not providing enough AMPs, while it tries to maintain the correct VOLTs. (Thus, the stated above solution, or you need a PSU with more AMPs on the 12v rails, to match the cards draw.) When buying a PSU, you want to mind the RAILs and the AMPs per rail. +12v/+12v (2 rails) *may not be split correctly for 5 cards, 2 @ 30a each (great), 3 @ 20a each (starved) 60a/60a +12v (1 rail) *better for 5 cards, 5 @ 24a each (ok) 120a NOTE: Without something on the +5v load, you may only have 50-80% of that amperage on the 12v rails. Voltage will actually drop to 10.5v-11.5v once the unit starts running, on the weak rail, in a multi-rail PSU. That, or it will remain 12v, but be lower available amps then expected. Only 30a-45a per rail, in the dual-rail setup mentioned above. That is just an example. I will know more detail about each cards individual "ideal power consumption", as my unit arrives for testing. Good info reenforcing what was seeing as I was checking out PSU's. For the latest PSU's look for 'certified for Haswell' and/or the equiv AMD power spec. Basically means they are just fine with no load on the 5v rails to work with the latest near-zero power cpu sleep modes. Also again, double check the power specs vs your power line voltage. On several 'consumer' PSU's over 1,200w I saw that many (not all) only give full power when fed from 220v. Their 110v ratings are much lower. For all server PSU's over 1,200w I've looked at that is 100% the case. |

We're still working and shipping out over the weekend, if you haven't received a tracking number today, it may be this weeked. What's you're order number?
My Number is 1562 Probably not this weekend. We're getting several requests for rigs instead of full miners from earlier order numbers. And by default we need to meet those orders prior to later order numbers because it wouldn't be fair. Works for me (3 higher than ^^). My now 1.1-1.25 TH/s Ant pharm (eating 2,496w) is tiding me over for now. |

AMT_miners I am going to need to give you an alternative address, the one I asked you to ship it to but did not. (my workplace). Is there any way I can give you that address instead to pick it up? Also, they left this miner on my step without me signing for it.
Yes, please send over the alternate address and we'll arrange a fedex pickup from that location. Again apologies for the shipment, we'll rectify this situation with a new machine asap. This really is the first time we've seen a miner have that damage. Glad I emailed Alyssa about making sure it goes to my business. Gave her the address again just in case but is also stated on my account dashboard. Um, please do make sure of that. As like many there is no one home except for my parrot during reg work hours. (remember those?) Okay, so most prob don't have a 35yr old parrot but still  On the paid invoice she sent me for my rig it lists my home for both billing & shipping which is not right. |

No matter what, obviously file a damage claim with the shipper!

Hey all,
Jim is fine, just palpitations due to stress, he was instructed to take a few days off and we will be back up and running on Monday. This is a very stressful business guys.
Shipped out more miners and rigs today, again to guys on here as well.
Really, great! What is my tracking number? Got a hunch you and I are near the end of the line though I did opt for the kit. |

Hmm. Since FedEx accepted the package then technically they should be responsible for the damage. Just like the post office they have every right to refuse a package if it is obviously not packaged correctly.
Assuming it was insured for full value... ya might be able to get your money that way? Quest is, who does FedEx pay - you or AMT to build you a replacement?
