Speaking about BACKPLANES... I'm still waiting for my BACKPLANE.

I got at least two cards that have their power connectors torn of due to a bad shipment.  

How about

(1) I send you these two cards (in the hope you repair them) in exchange for the two broken cards you identified.

or alternatively....

(3) I send you these two cards in the hopes that you have a better chance on getting them replaced when you meet AMT in person.

One last question,

are all your boards with orange or blue heatsinks?

Yea I was thinking the same thing too. The extra cooling won't hurt. going to put them on both ends to just reinforce airflow. I got a "lid" of sorts to keep the airflow within the heatsinks.

@Casey, with the blown boards do you know what caused it? were you able to sort out the reason why it failed? Just curious so maybe it can be prevented, thanks. It shouldn't even need to be done but knowing that might help in avoiding these from failing.

And how were you able to manage 6 cards? I thought these things came standard with 5? Did you get a 6th? how did you get it to work?

my recomendation is get two more high flow fans at the back. either in a push pull or both push to cool the back chips as its not cased the air flows straight off the top

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.

Thanks! ~

Very Respectfully,

Not gonna disagree you are right about it being business to a point. That is correct its a business transaction. That said it also makes sense to follow that transaction with a diplomatic manner so there is always a personal component to it. And that requires making good on your word. I spoke to my own personal experience with meeting Josh. I think I am what the 3rd person to have an actual personal interaction with him from this forum. Phin being the second and Mblackout being the first (speaking about people in this forum). All I did was relate what I saw and my OPINIONS on it. Now people have a choice to either wait or proceed with legal action. I got no impression that they were going to try and screw everyone just that they were looking to make this right for everyone. That I also stated. Everyone here knows they have the option and likely most already have gone the legal route.

What are you contributing to the discussion besides a bad attitude? IF my miner is a "half-ass working miner that needs industrial cooling to keep from overheating". What do you suggest from a technical standpoint to make it work? For every technical problem there is usually a solution. What do you suggest? If AMT does not offer the solution well the community can help each other out for those of us that have working hardware maybe can lay out some insight into how to better get their hardware going. I know I have been trying to contribute with whatever I can when I can.

Once I power it on and it does its thing I will report back on that. If it doesnt work then everyone will know it and also know why.

@Friction, I am going take a look at my miner once I get home and the back-plane. If the back-plane requires no actual firmware or special software to work then its possible to rig a cable up to make this work. while unfortunate it might be a better situation to get your miner working. Obviously you have your options but hopefully this idea might be worthwhile to make this work. That also depends on whether you even want to go that route. Its also cheap to do if its possible

At this point the company thing is a moot point. Its been beaten to death. We all know For those with the hardware we may as well help each other out as that is certainly possible. This hardware uses fairly standard component connectors and opensource software so its possible to make this work. If there are physical hardware problems then that's a different matter altogether. Blown chips and cracked PCBs will require obvious replacements.

Good to see Joshua Zipkin has time to log on to delete my posts, but not the time to address the many issues you have all brought up.

Josh, you are a stupid little man. I hope you end up in prison for all of the fraud you are perpetrating.

Opieum: I'm sure you will end up like many here, with a half-ass working miner that needs industrial cooling to keep from overheating. No one gives a shit about "how stressed out Joshua is" or how you've summed him up to be a good genuine person because of your 'judge of character'. This is business not personal, and he's done a terrible job so far running this so-called business.

Friction: I am wondering why you are investing more of your money into buying parts to get this hunk of crap working. Follow through with the suit and try for your refund. At this point you are just digging yourself further into monetary loss.

I got 5 boards on the setup. I also got what appears to be less fans on the design. Two larger fans pushing air through. I think from an airflow perspective that will work just fine. I will post some pics tonight to show what I got. I should have one unit functional tonight as it is so I can start with some initial observations and issues. From what I understand they did some work to compensate for some of the issues bitmine was having. Hopefully the work and the review I do on the 1.2 miner helps others here having issues.

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.

 

Got no indication of that. Nor did I ask. I really had just planned on my own PSUs anyway. Seeing that the recommendations for bitmine was those LEPA's I ran with those. But until I have my miners up and operation between today and Sunday I wont have any more to say on the function. I will post up what I find. The review thread will show it.

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.

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 curious because AMT said once they receive the psu's even the kits would ship with them. Since they aren't communicating I was trying to get a feel for whether or not they have gotten in their order of power supplies.

Possibly. But those other heatsinks arent covering all the chips either. Which is odd by itself.

The Dragon Miners seem to have it on both sides,  so I am guessing that they likely have it done right.

Friction do you have a monitor hooked up to it? I would recommend hooking up via HDMI a monitor and log in as root and run ifconfig. Problem solved. The LCD thing is just a small display (personally its just a nice to have but not a deal breaker for me). Why wait on a part that will take you longer to wait on when you can easily sort it out yourself? As I will be housing these in a datacenter the LCD is next to useless for me personally. I will be implementing other monitoring tools to monitor the hardware.

No I bought my own (LEPA 1600). I had them already so it works out for me personally. Honestly if they are getting the PSUs and putting them in the full builds I presume they would be the ones they know work with their setup.  But based on all the reading I did in the bitmine forums seems like the LEPA PSUs are the way to go. And they are not too bad pricewise. From what freddyfarnsworth posted on it I went with that as it seems to work. Josh also made a similar recommendation based

Again 20A at the wall is a must. If you try to run these on a 15A circuit you likely will not get the performance you need. I will know once I test. I am going to do a full and objective review of the hardware itself. If anyone has suggestions I will add them on to the review as well. I am posting photos (no video 

I am going to be going the immersion cooling route after some testing with older heavily overclocked PC hardware. It might be worthwhile as I am not looking forward to monitoring individual chips on a regular basis to make sure they work.

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.
