I found something else worth noting. It might be nothing, but I am not taking chances. On one of my cards (which I am currently working on) I am cleaning off the excess thermal grease. It appears to be the silver compound. Generally speaking I am pretty meticulous about cleaning that stuff off just to avoid the off chance it actually causes a short. Never let it happen mostly because of this http://www.arcticsilver.com/as5.htm
It is possible this is causing some of the problems people are seeing. Only one of my cards had this issue with the grease the other ones are fine. I have cleaned it up and will be doing my initial test run tonight and have some pics up in the morning. It will be in a separate thread.
Topic: New Official AMT Thread - page 150. (Read 149472 times)
Looking back through some pics I've saved from the old thread and I see a few things to look out for. The picture of fried chips points to the cause: The two chips that burnt are first in line from the fan but - they are hiding right behind the cage divider. No air flow on them aside from a little turbulence as the air spills over the wall.
Moral - either perforate the hell out of any obstruction to air going where it needs to or move the card or remove the obstruction.

I got 2 power supplys 30 amp for each power supply I have enough power for these things .. its just the boards are not working .. I even repaired the back plane thing that burnt . How i repaired it i got one of those tiny cables from a bad mother board and connected it back with black tape . I mean the tiny cables from the circuit board . 3 boards dont work or seem to turn on if theres a way some one has had to kick start these things please share .. I tested each board individually aswell . Maybe there something we can do to the circuit board to make it work .
Ok so if you test each board one by one they ALL work? or those 3 boards just don't work when tested one by one? I just want to make sure I am understanding you correctly.
Plugging in each board should get you around 200Ghs each. If you are hitting those numbers testing each board then you are ok. IF your issue is with all 5 boards plugged in and 3 don't work then it has something to do with the power supply most likley OR you dont have enough power at the wall (hence 20Amp circuit at your location not the PSU)
Essentially make sure you have the outlet you are pulling from can handle 20A. That means going to the breaker box and checking for that. Normally those are labeled.
For the PSU what are the makes/models of the PSUs. That would be helpful as there might be some documentation on how you might need to connect them. The more info you can give us the better on what you have.
3 boards do no not work tested one by one . I got 2 30 amp breakers I had a electrician Change it . .. I took the 3 boards out and analyze them I don't see anything wrong with em maybe there's something I over looked . Or they just do not work . I gotta make some Roi on this 6 grand ugh these people are just a mess Should I just mail these boards back and label it with BAD BOARDS PLEASE RESEND ME OTHER ONES ? Has any one mailed in boards back . But AMT just ignores all my emails .... If by next week they do not respond I am going to small claims court in PA I hate the whole court system as they take forever to get your money back .
Has anyone been to the address where they shipped the Machined from ? the 355 Lancester ave one ?
That is their office address. But I would make sure you get a hold of someone before just sending them back. Make sure you get them to acknowledge the return. But yea clearly you have 3 bad boards if you are testing one by one and are still having this issue. Hopefully you used also a known working connector that worked on one of the other two boards as well? All I can think of at this point to troubleshoot that.

AMT please respond to my refund request.
Got an +5v floppy pwr connector feeding the back plane? It powers the link circuits.

Pretty much what he was told in the A1 dev forum. But put much more nicely.

Because it is not only heatsink. In such a low voltage and clock I can almost fell heat on my Technobit boards when I touch them. Something is totally wrong here with quality components or whatever ...
I am wandering if you bought complete Assam led unit what psu is inside Also?
Do you not have the larger heatsink that covers a whole side of the board? Or do you have a bare board with just little heatsinks? I am trying to understand the need for new heatsinks. The ones on there seem fine to me.
The Dragon Miners seem to have it on both sides, so I am guessing that they likely have it done right.
Possibly. But those other heatsinks arent covering all the chips either. Which is odd by itself.
Well, you only need to cover the coincraft a1 chips. I guess the Dragon Miner has all its chips on the center of the board unlike AMT where it is spread out at the edges.
I was under the impression it was a reference design. So all would be building them relatively similar based on the bitmine design. I haven't looked into it too deep but I might out of curiosity.
Bitmine has a revision 3 board that is different from the AMT (Bitmine revision 2) board. I believe Btimine had trouble with the revision 2 boards and stopped shipment of any system greater than 800 GHs. Don't know if it was a power or heat problem.
I think the current AMT design should work at around 800 GHs... 3 boards.
Same central positioning. Also note that they have 2 PCIe power feeds to the card. 8 chips >238GHs from the one board. Check the post date, Feb 3. Wanna bet that Bitmine was already committed to the spread outside idea and stayed that route. Maybe it was blind belief that somehow the power eaten when in turbo would just go away and a really really big sink on the backside would do it?
'Prolly the Chinese just saw what BM.ch had ran into, accepted the power loads and dealt it it properly. Also make it mighty easy to mount a liquid cooling block there...
After waiting 6 days for a response to horrible shipping and no instructions

we wanted to make a instructional video showing the setup process. I will send you that or any other kind of instructions asap.

What sort of PSU are you using? And how many amps you got running on the circuit they on? It might be how they are hooked up too. There are a few reasons why that could be happening. Maybe those of us here on the forum can help.
It would be helpful if we did know if AMT tested the boards prior to shipment.
The number of bad boards is indeed surprising. However, it does explain why AMT and Bitmine.ch have trouble shipping.
At this stage of the game, it appears that AMT knowingly ships without testing (or is aware that a board is bad). The only motivation now seems to claim that they are shipping. In the meantime, they leave almost every customer who received a unit in the dark as to how to make their system work.
To be honest, just shipping the units isn't going to cut it. AMT needs to provide technical support and needs to honor their MPP. A non-working system has a hash rate of 0 THs and IMHO is tantamount to fraud if a refund is not provided.
yes. Shipping a unit that does not hash = non delivery.

I've been emailing these guys once a day and I get crickets . I got 3 boards out of 5 not running . The only response I got was why arent your boards running really ?? I donno maybe check them that they work before they leave your facility
Same experience here.
Technical support is non-existent.

Okay guys, good positive/bad update.
I got 6 modules cards that run successfully. I have a ghetto-rigged backplane that I had to solder 3 times because the thing kept burning out for some reason.
Probably a bad board design...tisk tisk AMT/Bitmine.
The other 4 module cards I have ARE DEAD, they do not mine at all. I want a full replacement on these 4 cards AMT. I will post my statistics of the diagnostics on these cards.
I am currently mining at slush pool, and waiting another 24 hours before I post my STATS. I was running in TURBO mode, and it ran like a dream...
Josh, please message me so I can arrange a trip to you to pick up my BACKPLANES that you were suppose to ship to me 2 weeks ago. Also, to replace these 4 module cards you gave me that were crap. You told me you tested them, obviously not my friend.
Lets be cordial here, and settle this like men, I met you in person. Now play by the rules, and lets settle this.
Otherwise, we will have some other things to talk about...
PLEASE respond AMT whether by email or publicly.

what temps was you getting in turbo mode? also if you have the voltage readings too that would be a bonus
also how did you connect 6 cards up? my backplane only has 5 card slots
+1 to this. I would like to know also. I will be checking temps myself.
