Topic: New Official AMT Thread - page 94. (Read 149472 times)

As far as I'm concerned they have delivered one unit. Anything that doesn't work as advertised, or is faulty (no mare where in the process the fault lies) is not a delivered product, just junk I was sent.

Seems similar to one of my cards. It would pull power, especially to one chip that was starting to overheat while the other sinks on that card were warm but cooler. This was a non-hashing board that was still drawing power. Two other boards wouldn't detect but didn't heat up at all. They were properly plug in for power they just didn't seem to be drawing any (or any significant amount)  I really should invest in a multimeter.

Well, Woke to find the miners mining at 480, instead of the 580 where they were last night.

Turned it off, to see if that helped... It did. The middle card which was hashing at 98GHs, causing the 480, went back to hashing at 190GHs...

Came in this afternoon, it was back to 480GHs... Rebooted it, and now the middle module does not report being detected. Not to mention the chip seems to think the first module is in slot 2 and the third module seems to be in slot 4, and it does not check the fifth slot. (Checked from slot 1-4)

The cards are in physical slot 1-2-3. (2 is not responding.)

Other oddity... it came online several boots, with the same IP address. Could have been just crappy random luck. However, I suspect it is more than that. As I assume once an IP is obtained, it would try to keep it after rebooting. Thus why the page stays up and keeps refreshing.

However, PuTTYing into the miner and killing the detected cars, did nothing to make the non-replying card reply.

So, now I am hashing away at a sad 380GHs until I can remove this "non-replying" middle card, and add-in my last "possibly good card" which I have not tested yet.

It is not the cards that die, it is the controller that replies to the backplane/ras-pi that is failing. The card was running fine just as all the others were, before they stopped communicating. Rebooting is the possible source of the issue. It is either ignoring the communications, or skipping channels, or the communicating chip that reports back is failing.

Time to break out the thermal imager, to make sure this one isn't burning up behind the failed communications. It is drawing power and doing something. Just not talking to the Ras-Pi or doing actual mining.

Once again, I have to take the whole thing apart, to replace the faulting module.

Will be using this heatsink for one of the other modules that came without a heatsink. Though now, the most I will get is 990Ghs, if I can get five running cards. (The most they do is about 205GHs nominal. With all cores running and no errors, with a target temp of 60c.)

I need a 6th heat-sink to get close to my 1.2THs, and at the moment, the 1.5THs is a pipe-dream for me. (Still not sure why I was sent this, like this. This is not what I asked for. So, I still assume I am supposed to be "fixing" or "troubleshooting" these. However, I can't do anything without the proper test equipment or schematics for these boards.)

Not sure if I should mark mine as "delivered"... lol (Since this is not what I asked for, and not one of the options they submitted.)

Mmm that's still $1,600 for chips alone per-TH (40 chips) with no discounts. They need to be maybe 1/3 cheaper to make the hashing density attractive as the selling point vs the A1's power usage.

A1 going rate is about $40+ 

The Bitmine and AMT prices are complete bogus.

You can tell what the price should really be looking at technobit price .

Random thoughts on A1 board packaging & cooling. Can anyone give me outside dims on the current blades? I assume thickness is 1/2" (the caps) and a bit more for the pcb. Say total of 5/8". Don't care about any heatsink thicknesses.

Been kicking this around: ya know with liquid cooling done right using cold plates I can see putting 14 or more of the current 8 chip boards in a 4U rack case with a 1U high PSU bank on top...

Thermals not an issue for any component and if can fit more chips on same size board - cool. Should help OC as well until com or other issues arise. Do this with other chips like BFL' CoinTerra or HasFasts new chips and whooo daddy! 10TH or more in a 4U rack...

Hmm. if the A1 chips get cheap enough might play a bit with some help from here...

+10 ^^

Query: on the SPI data coms for the A1, how does cgminer route it to the cards? In my Ant s1's they use Arch as the OS with  TP-Link and openWRT to handle it. I assume the s2's do similar as well?  I know the Ants are very graceful about chips going down with the rest in the chain cruising along just fine.

I can also see why AMT ignores you, Asshat. Unlike you I am trying to help the people out here who are having issues. I got enough time on my hands to do what I wish with my time. You spend your time posting up people's personal cell phone numbers and what commenting on my post count? Now who is bored if you have to look that up? What have you done to contribute?100 percent of your posts are bitching We all are in the same boat and are handling it in a way that does not involve constant bitching and helps each other get results.

 So yea I might have 80 percent of the post count but its also at least trying to help people. If you don't like that then go fuck yourself. I'm pretty tired of the comments I get on that both public and PMs on the matter if anything its going to make me do more just to piss the trolls and flamers off.. If you can do better than bitch about AMT not getting you miners then do it and stop talking shit. Unlike you I got miners (broken as they were) and got results because of my actions. You....bitch bitch bitch. And got nothing. At the same time I am making contacts here that are both helpful and in turn I have been able to help. A useful community vs useless retards who bitch.

When you can contribute better you can talk...until then STFU troll.

Oh my god Opium i see you are a very bored man...You posted on this forum 80% out of all..

Eh, not a fan of overt religious references. Zombies works. These things were half dead when we got them, and now they are being raised from the dead. And to be honest if there were burned out chips on them who knows what state they will be in starting up, if at all. Hence zombies. Could be missing a chip or two but still work just like a zombie could still move even if they are missing arms, or crawl if they are missing legs same idea here. Hopefully the cards are not in some kind of chain themselves that if a chip blows it fails the whole thing. I am still figuring all that out from a design standpoint.

Uh... I think project name should be called 'Lazarus'.   Zombies are living dead,  these AMT systems are more like vegetables than zombies.

I did a review of the code on github for the A1 driver. It appears that improvements were made to the delays scanning. However I am having this information confirmed as driver coding is not my strongest area. I asked a few more questions on improvements of the driver since the first version was made available. This might be helpful for us in getting these cards working. Since there is not alot of documentation (well none at all) on the AMT variants of these cards, this is alot of trial and error and guess work. I dont know what the result will be, BUT I am hopeful we might get some results and answers. Even with a single fried chip, it should be possible to bring the cards up partially unless they are chained in a way that brings the whole card down.

This is one hell of a learning experience here for me FYI. I know linux and am getting deep into hardware areas I never did before like drivers. So wish me luck. If I get a working miner/card tonight I will post an early alpha for testing. Once the initial step is done (zombie cards) I will work on features like a web interface and such which I will add later or someone else can. My plan is just a simple working base setup. I am going to call this project zombie lol. Seems like an appropriate name to get these miners back from the dead.

Hey,

No one is in their office but when I called the office number, I heard the phone ring, so it is in fact their office. I'm headed to the lawyer's now. Will post with updates.

With a name like termonator they should be shitting bricks.......lol. All joking aside tho, Hopefully you get results, if so could you please post up your experience?  Also you could walk over a few feet and talk to the class action lawyer who might give you some status on where the case is at. They are in the same lot there if I am not mistaken. If not they are a couple buildings over in 361 lancaster. Again if you could post it would be most helpful for all of us. Thanks

Can you tell if there is anyone at the office?   If not,  you can you go over to the lawyers place:

361 West Lancaster Ave
 One Haverford Centre
 Haverford, Pennsylvania 19041
 Toll Free: 866-399-2487
 Voice: 610-642-8500

and see what progress they've made. 

Hey AMT,

I've sent a bunch of emails your way and called a few times letting you know I was going to reach your office today. I'm outside now and was wondering if you could have a representative bop on over here so I could discuss my order face to face.

Thanks again,
Allen Myers

Until I know what the exact process is and all that I am not shipping anything. I don't want to go through the ordeal mrpark went through. Simplest thing too tho, they could ship me the miners and I just ship them back in the box the new ones came in they just have to include a return label. This is pretty much how manufacturers do it. Phone, Cable all sorts of equipment is handled this way.

They do have enough information to go up against IMET for defective hardware. Who knows what the deal is there. At this point we are all in the dark until we arent.

I doubt you'll even receive those replacements. 

The AMT claim is that IMET is witholding them in exchange for payment.    It explains why only a few have been sent (even if they're broken) miners.   There are a lot of other folks that have received nothing.

BTW.. do let us know when you ship those miners back,  I want to know if they receive it.

At least the lawyers MIGHT tell you why. Chances are they won't...attorney/client confidentiality and all that. Dont expect much on that route. I think behind the scenes a shitstorm is brewing. My guess is whatever it is things will be settling, but again very little of it to our favor. If AMT has little we are screwed. I haven't gotten any replies either (I got some occasionally when I needed tech help). Its likely pretty bad though...they could be undergoing a full audit now. Which might give the plantiffs a better idea of what is going on and what we all get....if the class is now a full class then all of us otherwise just the original plantiffs walk away either whole or with more than they were supposed to get which means our money as well. This could actually happen. But as I am not a lawyer I don't know. At this point all I want are 2 replacement miners to address the issues with the current ones.
