"(1) 1 in every 8 coincraft A1 chips are claimed to be defective. Which should not be an issue since you should be able to test a chip before you mount in on the board!"
Not that easy with power BGA devices which pull most of their heat away through the bottom contact balls. The usual ZIF test sockets cannot be used because they are not designed to pull away the heat from full power testing and ya can't just slap a cold-plate on top of the chip but - that is an issue between BM.ch/CoinCraft and Global Foundries who make the chip. Obviously GF was told to not test the chips under load (more expensive), just do limited go/no-go.
Then again, considering it typically cost 50-100million USD to bring a 28nm node chip into production, one would think that maybe 5% more to cover 100% full load burn-in would not have been a bad idea...
You are correct there, there really is not something we can do there. Also trying to re solder a pre-mounted chip is a pain in the ass, and expensive because it needs to be done by hand. At $65 for removal - replacement, its better to just get more chips. Also we found out earlier on that the 1 out of 8 chips is not a bad chip, but more just a weak link, and this has a direct link to the amount of voltage passed to the weaker chip, it needs a stronger current, and if the current could be modified on a chip by chip basis, than essentially we could get the most of that chip. The current daisy chain design does not allow for that, and actually if one chip goes in the line, they all go and you'll get a error message of "No A1 Chipchain Detected." It really comes down to the board design. |

We've shipped up to the 1200's - a few hundred thus far, earlier batches when clients agreed to take the risk and receive their miner despite heat/pcb problems.
AMT, could you clarify this for the group. How is it you are up to the 1200's when the 500's - 700's are still waiting. maybe the question needs to be more specific. Approximately how many coincraft machines have shipped and what number range shipped out last week (of coincraft machines) We have clarified this point, but it'll be faster to type it rather than search through the crap in thread. Over the last three weeks we have had several clients who have heard of our delays and have opted to receive miners even with the possible troubles. A few (3 or 4) of these clients where chip buyers as well and in turn happened to working with, or doing something from a board/pcb level. We explained the problem with the cage and we explained the problems with the boards and they opted to receive their miners anyway. We had them sign a waiver which stated they know the miners are beta condition and they wish to receive them anyway, waiving any RMA rights and what nut. A few of them overclocked them and had troubles, others got it to work and gave us their advice. In total these were 36 clients and 140-some miners that went. Of the 140 some 8 of them were full miners in cases. The clients that opted to receive their miners with possible defects were mostly technically oriented individuals. Each order ranged from 1 to 22 miners. 22 behind the most of course. Some of those orders were in the 600's, 700's, 900's, and even 4 of them were in the 1200's. We have not shipped all the way to 1200 of course, but after this upcoming we should see a substantial increase in the amount of miner testimonials posted on this thread. Thanks for clearing that up. I do appreciate the information and your participation here and understand your frustration as I hope you understand ours. We understand your frustration and share it. Please know that what ever profit we thought we had made went into the same investment you guys made as well. And we are in the same boat you're all in, and we doing what ever we can to speed this up. We will try and be much more transparent about issues and shipments and everything else. |

I've read through this whole forum, and it seems like they actually build miners, actually exist and are being harassed by people that are not even clients!? WTF.. And instead of helping them which they seemed to have asked for help several times, you harass them on a forum and hurt their sales, and threaten to sue them so they cant afford production?
You people are honestly very sick. And it seems to be the same on other companies threads as well. Yes everyone in the industry is late, but as a new buyer, I see that in America I can only buy from Cointerra or AMT and AMT (according this to thread) is delivering actually.
Here we go again... another 0 post count fan boy of AMT's. Let me help you out kiddo.
sit back.
listen and pay attention.
stfu.
no one wants to hear your opinions.
you don't know shit.
HERE ARE THE ITEMS AMT HAS LIED ABOUT.
1. they lied about my initial delivery date
2. the lied about updating this thread every week
3. they lied about keeping an order queue
4. they lied about mailing me a refund
5. they lied about wiring me a refund
6. they have lied about saying they would hire people from this forum (twice)
7. they lied about something as dumb as being associated with Freemasons
8. they lied about my second delivery date
9. they lied about being able to pay with credit cards on their website
10. THEY LIED ABOUT PAYING BRUNO 20btc
11. ANYMORE?
AMT IS RUN BY A CROOK CALLED JOSHUA ZIPKIN. IF YOU PURCHASE A MINER FROM THESE GUYS YOU DESERVE EVERYTHING YOU HAVE COMING TO YOU.
Criag, we're suing you. Just a heads up. |

Guys, Just wondering does the whole unit shutdown on overheat, before things burn out, just thinking of single fan on top if it fails what happens? I hate for it to become a really expensive brick? What's the wattage on this? 1.12 w per ghs in turbo I've read through this whole forum, and it seems like they actually build miners, actually exist and are being harassed by people that are not even clients!? WTF.. And instead of helping them which they seemed to have asked for help several times, you harass them on a forum and hurt their sales, and threaten to sue them so they cant afford production?

Yes everyone in the industry is late, but as a new buyer, I see that in America I can only buy from Cointerra or AMT and AMT (according this to thread) is delivering actually. Yes we do build miners and yes we have been delayed in our production and several other things until this point. Manufacturing is on track and increasing every day, miners are going out by the dozen daily and we expect to have everyone's (even clients which ordered last week) delivered over the next week. |

Do me a favor, Josh. Please send me that cease and desist order so that I can jack off on it, take a pic, and post said pic on the internet.
Yes we did serve Bruno with a cease and desist order in the state of Pennsylvania. We appreciate how he just admitted that on a public forum. Bruno did promise to stop his antics, and he himself offered to moderate this thread for 1000 each month. We said give us a week and show us how you can turn the thread around and he said he would really try. |

four weeks ago we hired a design team to help us design a customized cage for the modules. We could have always opted to go with the swiss case and produce but even they have been modifying that as well.
The design team ran us up quite a lot in a week or so and we ordered (quick turn from rapid sheet metal in NH) 400+ cages.
The designers did not leave holes in the cages for airflow to pass over the top of the boards (chips/chipsinks) but more over just holes which were the exact size of the heatsink fins.
So with the chip's data sheet specifying airflow/thermal dissipation 30% on top and 70% on the bottom this would work and chips would over heat. So we're stuck with 400+ sheet metal cages that dont work - we got quotes on cutting out the pannels of the cages, drilling holes etc.. So what's the quick fix to fab 400 sheet metal cages.. New heatsinks.
We ordered new heatsinks with more fins and 3mm fin height difference allowing us to utilize that gap for chipsink thermal flow. New sinks took 4 days to come in, cut to length extrusion, and 2-3 days to CNC from a nice guy with great pricing who has become the end of the day bitch station of all the things that went wrong during the course of the day. So the next week became a early morning and late evening pickup of heatsinks.
designers back in the lab charging us to fix the mess they made and we told them this time - make it like a fence. So they finished after a few days and sent the designs back to Rapid - who turned it around in a week (not very rapid) and sent the first 100 units over on tuesday and what did we find out.. the designers did not add the 2nd and 4th screw holes on the back side of the cage..
Called rapid they said send it back - quoted a week or two in turn around.. called larger shops they weren't available didn't have any time for quick turn runs...etc You're thinking so what .... it's only 4 screw holes you can drill them yourself, not quite. The holes need to be exact to the mm because if they are off by .2mm than your backplane wont fit in the right way and eventually lead to more problems.
CM offered up a quote of $10 per cage to have a few guys they know come in and do it. Also referred us to another character that came back rather too quickly with quotes in thousands. Trying to do several ourselves, some came close but nothing professional and came out with correct holes spacing but bent sides etc... just a world of crap.
In the end the nightly complaining at the CNC shop (heatsink pickup round 6) we mentioned it to our cnc guy and he was like ... "we can do that, $2 a cage done in 48hrs."
The CNC was already set to drill and tap the holes on the sinks which was the spacing it needed to be on the cage, so he was able to make a sheet metal template for manual drilling and had one of the shop minions do the drilling.
Moral of the story - ask everyone, call around and get quotes, but ultimately the guy that runs that CNC is gonna know what to do and how to handle shit situations.
This is one of several factors that has attributed to our delayed status.

Guys, Just wondering does the whole unit shutdown on overheat, before things burn out, just thinking of single fan on top if it fails what happens? I hate for it to become a really expensive brick? The chip itself has an overheat threshold which is around 130's C. If the chip shuts down, the chain breaks cause the whole the unit to basically shut down from a hashing perspective. If you're using putty, you'll see an error message similar to CMD_READ_REG ERROR. If you see this, unplug it, wait 30 minutes restart it via putty and do the following: root amt killall cgminer cgminer -DT And check to see if the cores in each chip are ok. Also there are two 4-5 fans in this case. There are two 140's under the cage blow air up through the fins. The 200mm exhaust on top and the 120mm x 1 or 2 in the front of the case blowing air in. Perfect, I can use the top 200mm for exhausting and connecting ducting and funneling, i.e. cold intake surrounding, thanks for following some of my earlier advice... I've worked on unix/linux for 20 years, I think I can manage to restart cgminer, thanks for steps though anyway...sometimes cgminer bombs out, sometimes it just hangs... if you do have s/w fixes or workarounds are you going to place those in client/customer area for d/l and updating the s/w on the pi? We bought you (and everyone else who wants one) rackmount cases (RPC-450B 4U Rackmount Case) Naran, do you want the desktop cases instead? |

Right, except that we don't hold bitcoin, that most CM's and parts companies like digi, mouser, etc accept USD not BTC. But yea, get a restraining order from a company that you're contacting every other day, that's brilliant. You must not understand how a restraining order works. That one enjoined hashfast from using bitcoin. One for you would probably involve your bank accounts. From the posts in this thread, I would be led to believe that you don't actually let anyone contact you, as you don't seem to answer phones, emails, etc. So wait.. While a hurdle of clients were asking Hashfast for refunds, most of which had paid in BTC, suddenly got a restraining order from using BTC - essentially not allowing them to pay people back? Well that was smart. And your advising users here that paid via BTC to do the same to us in order to a get refund. Yes, because for two weeks Hashfast is legally prevented from using or hiding those bitcoins, and failure to obey the TRO will lead to them going to jail. Until they show up in court to defend the way they treat their customers, much of which is the same with how you treat your customers, they don't get to run off with the money / property. And when they could have refunded easier when the rate was higher now people will get their coins back when the rate is lower? Either way, it was stupid. Now preventing us from accessing our bank accounts that's a bit smarter right. But via BTC sounds like a setup to not pay BTC buyers back, which is less troublesome than dealing with clients which paid in USD. Sounds fishy.. was there any real court ordered documented verification of this other than an press article? |

Please don't post my details here, just send me an email update, I choose what to post here, thanks.
Or, perhaps just update the order status on our AMT Account page maybe?  We might be able to do that. |

I've said multiple times, I have not and would never order from you. If I had, you would know about it, and I'd be one of those people that you either provided a miner to out of order, or a refund.
Oh so you're not a client? If you didn't order from us, that means that you're not a customer, is that right? |

AMT has been posting a fair bit of info. And they said 12 days roughly now. Considering bitmine has been late also, this might be part of it too, but AMT might want to confirm that as well. They cant exactly talk about every aspect of their business either, there are trade secrets to be kept for any business. That said SOME transparency in operation is possible. But again there is alot of anger right now that needs to be handled first. Getting miners in peoples hands I think is something they are working at. I never really saw any complaints about their 80-128Ghs orders which appear to be in peoples hands. They had the hardware.
So for the 1.2Ths ones It would make logical sense that this would also be related to the bitmine issues as well as well as some of the other supply issues they are having? AMT can you confirm that? This is what I am piecing together from the various things that I have been reading. PSU shortage certainly can screw things up. Case supply shortage can as well.
This is all just speculation on my part of course. AMT can confirm that or it could be something else altogether. But at least if we know it might be for (some) more understandable. I am sticking around to get my miners. I figure Ive waited longer for BFL and likely will see this before I will see their hardware at this point. I put my order in just over a month ago with AMT so I am not hurting too badly in that sense. I do feel for those who have been waiting alot longer and were promised sooner. But it is unfortunately how preorders work sadly. BFL I ordered in mid November and each month its a new thing about why they haven't shipped. AMT at least seems to have some out in the wild now. That's a hell of alot better than none at this point. My position isn't popular but it's the truth at this point.
Just stop sucking up, apparently if you want your miner, you have to go down there. Otherwise they stopped offering discounts for positive reinforcement months ago. Rick, what's your order number? |

Going on the offense? You have been doing that the entire thread. Bring it.
How have you possibly shipped orders up to the 1200s, when there are people posting here every day with orders lower than that asking where the hell the miners are? Or did you mean to say, you have shipped a few orders IN the 1200s, to people who have filed enough complaints to warrant action from you.
Don't try to assume my answers, or that I'll doubt everything you say when you provide proof of what I asked. You're a little shithead, and you have no room to act like a victim here.
Whats your order number Rick? |
|
|
|
You want a list of questions?
How many people do you have assembling miners?
Do you have parts for all the miners that have been ordered?
If not, are you buying parts piecemeal as you get more funds from new orders?
How many miners ARE YOU BUILDING every day?
Are you shipping miners in order of order numbers?
What order number have you shipped up to?
Do you see how answering some simple questions like that could provide your customers with actual information that would quell much of the anger?
Also, since you have lied numerous times about some of these questions, like when you said you were shipping orders in February, some pictures of the inventory of parts and the shipments of miners would help. You say you have enough cases for the next 500 orders? Mining PCBs? Take a picture of them, in bulk, from far enough away to show the total quantity. You say you are shipping miners every day? Take a picture of a stack of outgoing boxes.
Simple!
We'll respond to this one but after that we're going on the offense rick. We assemble in two locations - one with 6 assembly people 9-3:30. The other with 3-6 people depending on the day and everyones schedule. We have purchased parts for all orders up until March 18th, no we're not going to go ask the CM's if we can go in their parts cages to take pics of our components, that's just weird. And you'll end up saying - those could be parts for anything. Best day so far was about 22 miners built and shipped in one day. But half of those were cage only miners for a few of our farming clients. So full miners the best day was around 15 units built and shipped. Please account for the heatsink station - individual board testing station, 5 in a cage testing station - before it actually goes to a case assembly. We have 8 tests board on heatasinks must go through from the time we receive them from of AOI and manual inspection before they actually placed in a cage. Yes in some cases we're shipping miners in order, but sometimes if a client comes and assists to build other clients miners, we appreciate that kind of effort and will let him take his/her miner at this point. We've shipped up to the 1200's - a few hundred thus far, earlier batches when clients agreed to take the risk and receive their miner despite heat/pcb problems. Tomorrow well go take pictures of boxes on pallets if it makes you happy. But you'll still break it and down and find something wrong with it im sure. We'll even get the fedex freight guy to do an interview but then you'll just counter that with some excuse. but all the things even writing this response takes away time from support and other vital things. but we're going to start playing offense soon, so its cool. |
