can anyone tell me where to find the screen shoots of the setup page.  Wondering what the FREQ: Mod_1   Mod_2   Mod_3   Mod_4   Mod_5   diff: means, and what they should be set to. Thank you kindly.

the fail seems to be a problem with it. it says it's broken when trying to extart it. is there anywhere else to download it from. Thank you

reserved webgui, howto


Quick Notes/Issues (WIP) Will be edited with a more formal howto

If you did not flash the image provided by AMT, please note the IP is unique PER MINER and statically set. I had to pull it from the /etc/network/interfaces file on the SDCard using another linux machine.

How to get it without hooking up the HDMI or needing a linux machine:

Pull your SDCard from the unit (requires opening it) And look at the number written in marker onto the SDCard. 192.168.1.X (X is the number on the SDCard) That is your IP. Monumentally poor judgement on that decision. I will provide those who PM me with a modified image correcting any weird issues I encounter like the IP and have it set to a default IP or you can use this method to get up and running. While I believe in the OSS model I feel that AMT will profit from my work and not give due credit or compensation for it. Hence my need to approach it this way.

Other notes the miner uses Rasberrian. Apt-get and other tools for customzation are in there so it is more friendly to configuration (within limits) than most of the other miner tools out there. Depending on your skill level I would caution against modifying it. But if you are comfortable with linux customization I say go for it. Even upgrading to the latest cgminer if it uses an unmodified A1 driver.

FYI According to AMT this is the login for the machine SSH and web interface
*Note this is AMT's info. It should work. If not please report here I can provide alternate workarounds if it does not*
User:  admin

Password to ssh is:
root\stone201405

Since AMT has chosen to take down or delete the dropbox link I am rehosting it here. http://[Suspicious link removed]/q5rl56g This is the amt_a1_0820v01 a.img.bz2 file they posted.

Here is a FULL backup of the stock image. The ONLY modification on it is the IP address which is 192.168.0.245. As AMT has ceased to support any of their stuff, it seems appropriate to post it here.
Please note this is a torrent link. Use the torrent client of your choice do download it.

FINAL THOUGHTS

This miner is not as efficient as it could be. Considering the size, and power consumption on the miner 1300, not to mention the various other issues that customers have had with just getting them, I cannot recommend this as an option to purchase. For comparison on price AMT charges 1200-1350 for these devices (again a problem as its a variable price) for what basically is 1Ths @ 1200 watts. Compared to the same amount you could spend on 4 Bitmain Antminer S3s get 1.8Ths @ 1475W for the same price. The choice here is clear. Despite my other issues with the company, the device is well built. BUT they really need to work on power consumption.

Hi. where can I get the img file firmware for amt 1.25 ths system. My amt web site no longer showing me the home or setup link. Thanks



PART 2:

Reserved for power consumption, hashing stats

Initial Hashing stats. I will post a more sustained average from the miner later on this is just to start.

What the pool reports after about 10 minutes. This is on BTCguild. I will move the miner over to elgius for more accurate stats.

http://i.imgur.com/rP557Ik.jpg

While there is a 12 hour average here. This is pretty much what it looks like all the time. I think the 1.27Ths number is fixed and always in there. No matter what I do that number will not change. The pool reports

This is about the norm. Usually a but lower at around 950 most of the time. The performance is not consistent and this is actually the best it can do. Looks like other people who reported a 10 percent rejection rate. CGMINER stats coming soon.

Wondering where can I get the AMT 1.25TH firmware img file. Thank you

What firmware version are you using?  I tried amt_a1_0820v01.img that AMT posted but it was giving me errors about using the --rock-freq flag in cgminer.

Which miner do you have? I get the impression they are a bit different. I got a rackmount one with 5 cards. Yours SHOULD be the same minus the rack mount case.

I got a desktop one which looks almost the same as yours, except for the casing of course, and the Pi.  So are you using the amt_a1_0820v01.img image?

EDIT:  Looking at your UI screenshots you're almost certainly not using amt_a1_0820v01.img  The one you posted looks like the one my unit came with, except yours shows the temp and mine doesn't.

The UI on the amt_a1_0820v01 image is a slightly nicer:

Do you know where I can get firmware for a AMT 1.25TH/s 4U? Reason is I'm not able to change the pool or stop the miner ex.. I lost the home, and setup link at the top. Thanks

As always excellent review. I will note the same as MrPark. The company should be avoided. Their hardware is deceptively advertised at rates higher than the hardware actually goes. The webUI reports inaccurately 1.27 all the time regardless of the pool rate despite the other numbers being refreshed. Leads me to think its a false hashrate. I don't see this with any other miner product. It's just another case of smoke and mirrors with Joshua Zipkin deceiving people. Also should be noted that ssh access is possible BUT sadly they don't provide that info or they lie about the logins. It required some hacking the image to actually get SSH working properly in my case.

FYI the SAME model is reported on their site as 1.3Ths. So again more lies from this company. AVOID!! Oh and according to them, I am their official support contact. I am not. They passed the buck off to me. And I am trying to get Joshua Zipkin arrested for putting my family in danger. That should speak volumes about the company itself. Considering he thought it was a terrible idea to send a review unit initially to dogie, find it hilarious he took my idea and ran with it. I will post the chat log later where that comes up Wink

I'm running a newer firmware version then the screenshots above and it does actually change values, and it does achieve higher hash rates. I do believe there are enough chips to achieve 1.25TH and its just bad firmware which is failing to achieve that hash rate. We had to go through several versions just to get one that would find the modules. Unfortunately though, he doesn't seem to have been around for a while and I had to publish as it had been too long.

when I go to AMT 1.25TH/s 4U web page to change mining pools it will not let me. It shows mining stat's page, but at the top it does not show the links home or setup. I was making changes I stopped the miner, and then click start again it froze up. I waited 6 mins then I shutdown unit, and restarted it. then the above problem happened.

Do I need to re flash the firmware if show can anyone post a link for it. With steps please.

Hope someone can help. Please, and thank you

I'm new to all this, and I have 19 of ASIC USB Bitcoin Miner- 335Mh/s Sapphire v3.00. Is there anything better that will work with raspberry pi Model B running Minepeon. which miner hardware can be used with this, and best place to get them? I maybe looking to expand any ideas? Show I use same hardware with rasberry pi or different hardware with rasberry pi?

So I think if my math is right I'm doing 6 and change Gh/s. I paid raspberry pi, and 19 of ASIC USB Bitcoin Miner for about $340 Cad.


Also what's the best website to exchange btc to Canadian $$$


Thank you in advance for any help you can give.
