Never said they resell boards. Somewhere else in this thread is was said that they ARE using Bitmine boards. Most likely bare ones that the CM's stuff with support components and mount the chips on. As for the CM's, most are assembly houses, not full up manufacturers.  Many many do not make the pcb's in-house. They just stuff ones either supplied by the customer or their manufacture is subed out to someone like Sunstone or other places.

The thread referenced is irrelevent - BMch did not a have viable board at that point though whoever Innosilicon was working with did. Noise in the the BitMine thread is that Bitmine has ended up using those boards rebranded.

Actually... Those here who paid with bitcoins already have the AMT wallet address stored in their wallet transactions log.

Not that it matters much. Hell I have at least 5 addresses I use just to keep track of what pool is paying into it.

So, anyone else here running Bitcoin Core program so they have the entire blockchain DB? I run it but that database is >18.7GB and I don't have the horsepower to search for strings.

AMT is the Authorized distributor for BitMine.ch products and as such it is a safe bet that they by contract can only use  the CoinCraft A1 chips and boards supplied by BitMine. BMch's travails are well posted in their own thread.

The 'other' A1's out there raises an interesting question about BitMine and Innosilicon. Details are sketchy at best but BMch contracted with Innosilicon to design the A1. Somewhere along the line it seems like Innosilicon was granted rights to sell the A1 by BitMine.ch. Now idea why and frankly I have never heard of a design deal like that. Possibly as form of payment for services rendered?

The A1 has a lot of standard Innosilicon IP in it, memory, routing and whatnot so I can see Innosilicon pushing matters if they were not getting paid or if there were disputes about the v1/v2 chips. They *do* work, just not as expected. (so even more off targets then what is being shipped now?) If that is the case, I can see Innosilicon pushing to be able to sell what v1/v2 chips had been produced and even keeping mgf/sale rights for those versions of the chip.

BitMin.ch is releasing orders now only for A1 v3 chips. Raises the question though - what version chips are in our AMT miners???

Looks like 1 miner chip company has learned their lesson from past fiascoes...
http://www.coindesk.com/avalon-asics-40nm-chip-bring-hashing-boost-less-power/

Note that Avalon is not doing pre-sales. The chips have been characterized and more importantly they are providing via github reference designs for various board form factors.

Gonna have to keep an eye on that...

I assume the AMT units use the RasPi? If so, ya. My Ants use the RasPi running Arch as OS and OpenWrt as the router for running data to/from the ASIC's. Not especially responsive to the outside world while hashing. Hardly a problem though.

I'd be game for that esp considering mine is for just what was the 520. Considering the blades are 200GH each, make it 3 blades, backplane, controller & special cables along with a guideline to connecting things & running it and I'd be happy.

Hmm could it be because Bitine.ch is the cause of all this. Face it, whatever you may think of the pair Josh and his fledgling AMT has been badly burned by this as well by BMch. If The A1 product had been properly produced - in other words chips produced and characterized to verify design specs, tweaked a few times as needed BEFORE taking full payment pre-orders - then none of this would have happened.

As it stands, safe bet BMch is taking care of their own direct orders first followed by what BMch doles out to chip buyers and miner assemblers.

Hmm, now their page doesn't even have an accounts link. Someone musta broke it trying to actually use/access it?

Now see? Doesn't that feel better getting that out?

As an industrial systems builder for nearly 40-years I can say, Been there - done that, yes it's Hell. With chips/boards so far off course, blind faith in all the rest being as it should be rarely works but ya do what ya gotta do.

I have one pert-near as good. Last year we get an order to upgrade 6 laser driller systems in Taiwan to our latest/greatest versions that literally have 3x the throughput, each upgrade coming in just over 300k$. Got in the PC's (with built-in Firewire to talk to everything else) and all the other hardware. got it all together, ran into a few issues & solved them. Ran each and every system 24x7 for 1 week. Perfect.

Got to Taiwan and physically installed the 1st upgrade <drum roll> the PC would not talk to the rest of the system. Firewire errors all over the place... WTF? Spent 2 days talking across the planet with folks trying to find out what the hell could have changed. Eventually just took the old FW plug-in card from the old PC, disabled the onboard one and all was well. Every system did that. 6 out of 6. Still no idea why other than the fact that Firewire can be a bitch to work with and if a combo of hardware works - get a lot of them and stick with it.

Nice bit is we just got an order from them for 9 more upgrades for this year

No doubt check the chips... If that is the package temp the internal die is going to substantial higher than that. Not a good thing to do. Is that temp sensed on the die itself or the chip package/bga pad area?. If it's the die, pushing things but not *too* badly if off the die... yikes.

Assuming you are running say over 5kw would be a good use of the waste heat and temps should be about right at least for hot water.

I have noticed that with my 4 Ant's the furnace stays off longer. Now to try and figure out how the electric & gas offset each other...

Ah for the good ol'days of Dow Freon(r) thermal xfr fluids... Some of the old Cray's had beautiful fountains as part of the cooling loop...

Rack mount ! Rack mount sis boom bah! Rack mount Rack mount rah rah rah!
Yes please...

6-sigma would apply to the chip/board makers, possibly to the CM's as well but is pretty useless for a AMT's small(ish) operation. I take it AMT is pretty much physical assembly of core parts into systems. Going through ISO-9000 on the other hand... Great for putting the business practices in order!

Or, perhaps just update the order status on our AMT Account page maybe?

Luckily I got in late to the BTC scene. Saw BFL's10G Jala's on Tigerdirthere ect in-stock of course) in early Feb. and said what the hell. Got me hooked. Since BFL has their own very fine Forum - I saw the Monarch Saga and stayed away since it was a Not There Yet product.

Ordered the A1 chip 520 (now maybe a 600?) on Feb. 27 only after seeing the A1 chip advertised from several miner makers. Figured must be in production so...

If ya mean about system design my 1st would about thermals on the boards. Specifically regarding how close are the filter caps to the normally rather hot chokes feeding each ASIC? Got a manufacturer pn-on the caps or at least a temp rating? Aside from what I read in the A1 dev thread (not-production boards much less in a rack) anyone done any thermal probing?

BFL's literally Flaming Jalapeno's, Singles and their PSU's come to mind...

Definitely avoid anything with the CoinCraft A1 chip in it as it is the root of these problems. Coupled with non-communication from the manufacturers both of the chip and systems based on it.... Insane. Now once the huge backlog - including compensation systems that BitMine.ch has promised their direct customers - is caught up and folks get kinks worked out of packaging, could be good but right no - nope.

Yes, ONLY on-hand and shipping today like Antminers. The Motha' that gave birth to 'pre-order' should have eaten it instead of the afterbirth.

 I get mine through Amazon, free fed-ex, credit card and vendor protection, import-fees already done. Well worth the extra bit vs wire-xfrs to the factory. So far Jones Gear there has the best deals.

"(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...
