@AMT

Not sure if you online tonight, but hopefully you can provide me with some info on the particulars regarding the driver (preferably the original C files used to complile your version of cgminer). I am trying to get an updated cgminer working and I have some of the driver stuff I would like to test. However the A1 driver changes that were made for AMT's setup I would need to know the specific changes to the driver-SPI-bitmine-A1.c....or any other cgminer/bitmine related driver file for this to work. Also the difference between the AMT and the bitmine backplane as first and foremost thats not being detected. Once I get the backplane detected, the rest I can start isolating the reset issue. If you can post or email me the files I can figure out where the issue is. Will save me alot of guess work to get the backplane charged up. I expect I might have some insight on being able to force a reset on the cards as well.

I have been going over Zefir's work, Trying to figure out where there would be changes for the AMT variant. Seeing as the original work is GPL this might not be a bad idea to post publicly or post on github for people to work on and improve. At any rate I am inching closer to a possible test but I need to see the actual files used in the cgminer build you guys have to make this work. Thanks

Yea ISA covered that. In some cases the assemblers put the heatsinks on apparently in a way that left airpockets...not a good thing. I have been mostly quiet as I have been working on the software side of things. Lotta reading on these issues. Its not just AMT having them. They just got hit the worst by it due to all the other problems with assembly.

If ALL 8 chips and all cores are working you should see 8/255 in cgminer....with this number you should see between 190-220Ghs. But if you are seeing MHs then its a VERY low number and something else. I suggest pointing it at btcguild just to get a consistent result for the moment until you are sure that the problem is not the pool setting. It likely is the card, but just to rule out any pool related issues.

I think it's the heat sinks causing the ASICS to slow down. They put a tiny square much smaller than the heatsink for attachment. I laid an aluminum heatsink and it works much better. I could feel the heat sinks were not greased right because they were not that hot. What a mess...

Opium/ISA would know for sure but sounds a little low. Think 200ghs or more per board is expected. Depends on what they set the clock and such at but I say sounds like a safe setting or maybe a chip has a few bad cores.

Question: I have 2 boards hashing at 380Mh is this correct for 2 boards? I guess all ASICS are working on the 2 boards. Any way to check individual ASICs?

Kudos! Better than a poke in the eye and at least something for now.
Did they at least get it right that a cable should lead out from a board and not have to be folded over?

Seriously, no reason aside from in-house profit point for an assembler to not use pre-made ribbon cables or even customs from the likes of Digikey. Dirt cheap...

The ribbon socket is keyed, and it works. I am just noticing some crazy bad electronics work... The red stripe on the cable should be pin one, but it's backwards. It hashes at 380 right now... Other boards are really damaged.

Red wire. The board/backplane are not keyed either so is possible to plug the boards in backwards. You'll have to look back or maybe Opium will pipe in but think the heatsinks face the ribbon cable end of the backplane.

But you want confusing??? SMD large cap polarity. Makes no difference if the orientation mark is red or black. Seen both colors used for both + side and the - side. Gotta know who made them and check their data sheet to know. LED indicator chips same way. from several makers the red family use a band to mark cathode yet for green ones the band is the anode. WTF?

edit: Looked in my pic collection and big sinks face ribbon connector. Don't forget to feed the little floppy drive power connecter next to it.

It seems they also put the ribbon cable in backwards. Maybe they did it twice why it works. Electronics 101, the RED pin on a ribbon cable is pin one.  I don't know what they sent me but these boards even have different caps on each of the boards.

Funny thing is as consumers you guys HAD ALL the power and you were throwing it away faster than they could collect it...  You guys made the pre-order model the easiest fastest solution for these companies to raise money (and what they raised was liabilities and not capital lol) so most of them used it.  Funny thing is once you guys handed over all the money the power switched form you to them.  We all have seen how they have handled the power you gave them, all cherries and ice cream before they got in your pants but then ignore became SoP once they blew their load.

There is a reason why the real world doesn't use pre-orders the reward simply rarely outweighs the risk.  The companies named above prove this point beyond a doubt.  Why do you think very few if any VC's were willing to take all the risk on NRE of BTC mining ASIC, because they knew the risk was so high that the reward could never come close to making it worth while for them...

The investomers of all of those companies got swindled by snake oil salesmen, the last resort is basically use the law to the best of your ability to bring restitution. Good luck guys I hope you get as much back as you can but it is going to be a LONG haul from here likely.

By and large no disagreement from me there aside from the boards timeline. Even on that someone should have at least said, 'Um folks... Oops...'  Not that anyone probably read it but on AMT's site under News they did mention on Feb.10  that multiple versions of boards may be needed. https://advancedminers.com/pcb-prototype-testing-diagnostics/ Why was that not brought here where folks see it?

Gotta love the closer on that page:
Especially agree on the pre-order mess. Still baffles me that the practice is allowed at all.... This endeavor as well as those by BFL, HashFast, TerraMiner and others should have been properly financed 100% by their own sources. Not unwitting Investomers.

Here is my issue with this complaint about poor parts.

AMT promised delivery on February.

If the boards were coming out of the manufacturer and testing bad in January, they should have informed customers of the problem and like any legit supplier, refunded anyone who requested.

Now we are here 5 months later,  nothing but bad shipments if any shipment at all. 

The point is this, do not ask people to pre-order if you cannot guarantee that you can deliver.  If you can't deliver then it is your responsibility to refund your customer.  It is like any other product,  if I order 500 barrels of oil to be delivered in February for a price of $100 and you can't do that because of someone bombing your pipeline, then you refund the $100 because you never delivered product.

Has AMT delivered working product?  No.   So we all deserve a refund.  Their manufacturing issues (if even remotely true) is their problem.  No sympathy from me.  They should have purchased insurance prior to embarking in this risky endeavor.   

The A1 chips are not in question as yes they are sourced from Bitmain/Coincraft.
It is all the other components on the boards that we are talking about: capacitors, resistors, coms chips etc. For those I'd think the normal distribution channels have enough to not worry.

Per what AMT said, I think specifically parts from NXP & LTC which are high-demand parts are what will need to be verified. 'Specially Bitmine pretty much bought up all left in the supply chain at the time.

As for chips with no dies/incorrect dies in them, again that has nothing to do with our sitch here. I hope. NXP is one of the companies that *is* plagued with counterfeits. Was a general reference to what has been found in many many cases where counterfeiters have been caught and prosecuted. This issue has hit many industries.

A good starting point on it is http://counterfeitparts.wordpress.com/ and http://counterfeitparts.files.wordpress.com/2012/02/avoiding_counterfeit_electronic_components_part2.pdf

I thought the chips were ordered from Bitmine, and through them, from Innosilicon. I'm unclear how the manufacturer would have any part of how the chips were presented. I don't know a whole lot about how ASIC chips work but it seems like that would be very hard to miss and take effort to ignore. Then again, I'm no engineer.

Lawyer said it was an opt out suit, unless you go to them and tell them that you are pursuing your own legal action, you are already part of it.

Very true and I was not meaning to imply they knowingly used counterfeit parts or that any were used at all. Was just clarifying to the op the possible ramifications of grey market parts and why they should never be used for any kind of commercial product without validation.

What does worry me is you mentioning specifically the NXP and LTC parts. NXP largely makes SOC (System-On-Chip) micro-controllers but other things as well. We use then in our lasers for all the background systems control and monitoring. Will be interesting to see what the miners do with them...

The LTC ones I assume are the Vdd switching regulators and if different than original spec'd other things (component values) usually have to be changed. Will be interesting to see what was done in that area.

Easy to find.... just google "Joshua Zipkin Fraud".

At the end of the day, they are the business that has taken everyone's money, and AMT has the final responsibility in this matter. So they SUPPOSEDLY hired some dodgy manufacturing outfit to produce the miners, and it didn't work out. They want to pass the blame onto someone else to cover their ass, big surprise.

Since the beginning, they sold themselves as the MANUFACTURERS of the miners themselves, now we are to believe it was all outsourced to some incompetent company that has screwed up by buying a bunch of parts off of "the grey market"? Get real. What about QA/QC? WAS ANY TESTING EVER DONE BY AMT?!

What about all those posts about how they have people night and day working to put these miners together? Are we sure the ball wasn't dropped there? These miners look like they were constructed by a 3 year old (smeared thermal paste everywhere, missing screws, missing parts, misaligned parts etc). Please, tell me who's to blame for the bullshit packing job and shipment (aka: destruction) of these miners? Is it Fedex's or UPS's fault? Who are you going to blame for dropping a $6,000 miner into a hollow box with a handful of packing material?

Just like the shipping, every FACET in regards to the build, assembly, QA/QC of these miners - was done HALF ASS. It's as simple as that. AMT's business model = wild cash grab followed by complete laziness. It's like once Joshua had the cash, he stopped giving a shit about delivering on his promises.

Besides, WHAT DOES ANY OF THIS REALLY EVEN HAVE TO DO WITH NOT GIVING CUSTOMERS REFUNDS? No excuse for this, though AMT would like everyone to believe the company was started with ZERO assets, except a drill gun and a cheap acer laptop. Now the customers have to reverse engineer AMT's incompetence for them. Let me remind you that there isn't a single person with a fully working miner, and it's nearly June 2014.

Anyone who believes these childish excuses, needs a whack upside the head. More stall tactics, and more blaming others instead of owning up and taking responsibility. Joshua, you're a fat, stupid, kid that needs his ass kicked. You've fucked a lot of people out of money, and now want to blame others for your own misrepresentations. Hopefully the justice system will deal with this retard accordingly.

Where do I sign up for the class action suite again?

I would like a refund, and have just started the process up.

What is the title and number of the suite?

I would like my money back. ROI is impossible on a 12K loan, and with difficulty, and only 3-5/10 modules running correctly with SHOT backplanes that I have resolded several times.....Yeah, I am throwing in the towel.

I'll keep what I have now, and prepare my legal endings.
