Topic: New Official AMT Thread - page 34. (Read 149472 times)

As for the new miners in production - lets just say as far as the miner designs go: Lessons learned and not repeated..

However, it is more than very worrisome that so far only the 1 has surfaced...  

For the 'official' and if needed legal record I have to date:

Received zero return on the $4089 I spent with them.
Received zero payment of any sort from AMT et-al.

For the sole purpose of doing qualified professional 3rd-party forensics of the designs and hashing boards - gratis mind you - I have received:
   1 pc TH miner case with cage and backplane. Yes arrived poorly packaged but mostly intact for testbed purposes. Ditched the case, just have cage holding 3 hash boards. 2 Briefly worked. Of the 2 - one still sorta does and is my sole remaining 'operational' reference.

  8 of the AMT hashing boards in total including the above - all non-functional in one way or another, several minus heat sinks and as-received from the CM. All from the various versions produced before attempts at production of the oft-revised designs as given by BitMine.ch and produced by the CM up to May-June (?) or so was stopped. No idea on the exact dates.

   2 main controller boards with pi's and cables. Minus the SD cards btw. Used my own and Josh sent me an image of the software.

   Diagnostics time to date: including pouring over the schematics, BOM's and looking up/through component data sheets, microscopy to verify physical construction & components used (and approved substitutions), hardware testing as in signal timing integrity, voltages, etc.: 47 hours. Again all Gratis for the BTC Community. btw - my commercial paid rate is well over 200$/hr when on-site. I am good at what I do. Very very good.

In other words - I have a forensics testbed and components all of which per contract remains property of AMT. I found EXACTLY what the problems were/are with those hash boards and reported to AMT what I'd found.

From only the hardware point, just who is legally responsible for the myriad of issues with the original miners and to what extent is for the courts to decide. I can categorically state that of this mess perhaps the ONE thing that AMT has done right is not shipping more than a hand full of what was produced. Things would be far worse here and elsewhere...
From the customers point - AMT and AMT alone are who is on the Hot Seat. Hardware issues be damned their general business plan has been sketchy at best.

So much for being a paid shill, eh?

Are you kidding? These guys have fucked customers every direction and in every hole. You think that if the thread was just left to a paid shill like you that more people wouldn't have been ripped off? They delete every negative post now as it is, so keep on trolling with your lips pressed on that scammer ass.

Hmm.. members like sirmines, RickJames, and a few others who's only apparent purpose on the Forum here and in other threads is to try and kick over the kettle and fan flames despite never having bought (or tried to buy) gear from the companies in question   Useless drivel - boatloads of. Useful information - zero. Their and your ranting opinions ain't worth diddly.

Bet your 2nd favorite pastime is to look for people on buildings so ya can shout, "JUMP!, JUMP!"

Yeah, go get life! Grab it by the balls.

He doesn't smooth anything over, he looks at things with a level head and has called out AMT on quite a few occasions.

I'm not Josh and you can see the history of my posts (https://bitcointalksearch.org/user/avaughan4-166777). I have berated AMT as much as anyone else on these boards. AMT still owes me another 1 TH/s miner, from their recall (https://advancedminers.com/amt-issues-recall-due-manufacturing-error/), and $2,609 in credit. Do your homework.

I'm just letting everyone know how it's going with the new miner. I had lost all hope already and wasn't even expecting to receive it.

On another note, I figured out why the Pools were not being load-balanced. The command being run from the web interface was missing the "--load-balance" parameter on the call to cgminer, after I added the parameter the 3 pool entries started to register work being done. I added both "--balance" and "--load-balance".

From file "/var/www/config.php" line 190.
Before:
$cmd =sprintf( "sudo ./cgminer  %s --diff ".intval($diff)." --api-listen --cs 8 --stmcu 0 --hwreset --api-listen --api-network | head -400 > cgminer.log & ",$str);

After:
$cmd =sprintf( "sudo ./cgminer  %s --diff ".intval($diff)." --api-listen --cs 8 --stmcu 0 --hwreset --api-listen --api-network --balance --load-balance | head -400 > cgminer.log & ",$str);

I also raised the frequency of the boards to 900Mhz and the hasrate has averaged about 920GH/s on the web interface and 880 Gh/s on the pool side, which is the side that really counts.

Time to put this retard (calling him that is actually an insult to actual retards) back on ignore. Understandable why your posts in particular get deleted.

Liar, ...! This is Josh him self..only one person out of 1000 orders received miners..and is this guy here..That would be pretty stupid to believe..

Shut the fuck up Opium, are you Josh's bitch or something?.... he is shipping shit.....soon AMT are going to log on from Jail and delete posts here in bitcointalk.

hahahahaha dude ...love it!

Since cgminer is likley already in the bin folder this should work. I dont have one the these new AMT miners but most are built using the same type of firmware so this SHOULD work.


If it needs tweaking feel free to post back the changes. This is nothing fancy just a simple way to start it. Also once cgminer starts up, you can also save this as a config which will insure it starts up like this without the script all the time.

About the UPS, ever do a pull the plug test? I've found that miners do not like standard off-line ones even if only pulling 2/3 of max rating. I've switched to real true always-on-line ones like this good for 1,300w/1,5kva http://www.cyberpowersystems.com/products/ups-systems/smart-app-ups/paragon-series/ol1500rtxl2u.html Zero-transfer time with them, rock-solid 120v out even with only 90v coming in.
From TigerDirect was $547 or 0.86somethin' BTC. Yep. TigerDirect takes BTC. Just too cool... I also have the 2.2kva one for 4 oc'd Ant s1's (1.8kw for ~800GH total - but still easily paid off and feeding themselves + profit ). Of course they display all the info you would ever want on power & condition as well with simple front panel display.

Cool. I can try it out and see if it works.

I don't know exactly how many watts it is pulling, nor do I have a gauge but maybe the interface can answer your question. The power supply can be seen in the case below and a close up picture of the power supply. The tower case is a standard size case, you can see all my pictures on page 125 of this thread. The web interface shows Utility and WUtility those read 22.6 and 86.24 respectively at the current moment. I have supplied pictures of the web interface and you can see those read 32.30 Utility and 84.07 WUtility.
I am using an APC Back-UPS BN4001 as the battery backup. Used a standard 110V computer power supply cable and the miner has been running well and the boards are cool enough to touch. I'm not well versed in electricity academics so I'm probably not the best candidate to answer these questions.

On the cgminer front (since you seem comfortable with the CLI) you could write a small script for that. Later on I can post one I use that will allow you to post multiple pools (easy to do). I honestly do not like the web interfaces in general. But if the web interfaces accurately queries cgminer then running it from a console and scripting it to start like that will work better. Might not show the pools but the hashing speeds should show up.

How big is the power supply? How many watts is it pulling?

Nevermind.  i see they are still accepting credit cards and paypal. Just not selling miners.

does AMT have a new website or are they still using the "old" one?? just curious, with all the positive press if they have changed for the better.
