Topic: AMT 80 GH/s miner review. - page 4. (Read 7953 times)

When ya figure it out, let me know. Wish I could work the magic again. Maybe it was just time for SOMETHING to go my way.

Or maybe it's this.


That makes the second guy to tell me it's the hat. I'm going with it. From now on it's my official "Bitcoin Stetson" 

Sorry,

orrible review.

4 minutes to open the box is not interesting. 

I didn't find this particularly offensive, please try harder.   

yes, good point. thx to OP for the review and videos. appreciated!

Certainly no need to be offensive towards the man. What did he do other than accept a miner that was given to him (Would you not?). He was even kind enough to post videos and reviews. How about some positivity - instead of your obtrusive and offensive comments (especially from a senior member such as yourself). This whole forum really has turned into a giant flame-fest.

Thank you for taking the time to post your thoughts and videos Biomech. Anxious to read more about it!

He moaned since God was a cowboy about how godawful broke he was and how desperate he was for an ASIC, any ASIC...

Congrats cowboy, nice that someone came through for you.

Next challenge: get a cycle maker to send you an evaluation mountain-bike...

-MarkM-

my question is how does a member with similar stats to me get an eval unit?
I believe I even have some rep here, I missed the boat I suppose.

So is this thing available now? Ready to ship? At what price? The first post of the supposedly official thread has been blanked out.

-MarkM-

So very true.


That's only true in few cases, usually 10% or less than the max capable load, sometimes more than that if the power rating isn't really good. In most cases you'll exceed that threshold, at which point the efficiency is almost always linear.

Subscribed to the thread.

I would also be interested in a closeup of the original label on the PSU if its still present.

As for efficiency; you may be surprised but most PSU's are less efficient when they are only lightly loaded. So the higher the capacity of your PSU, for a given power draw, the less efficient it will likely be. To be fair, its not easy to find <300W ATX PSU's and some models do well even at very light loads, but unless AMT found one that is > 100% efficient, I highly doubt they will achieve their claimed 80W at the wall. Most reports Ive seen suggest each of the two Technobit boards will consume over 40W by themselves if hashing over 40GH. Add to that the fans, USB hub, Raspberry controller (?) and PSU inefficiency, and well, you do tend to end up with more than 2x40W .

Few people will really care about this in a "80"W miner, but it may provide more insight in how honest AMT is specing their gear.

might as well have been. Old webcam. My good one got lost in the move. It'll show up eventually. Plus my son does not have a steady hand and he REALLY wanted in on that. I'll have better pix later.

We appreciate the attempt at the video, it was a total failure however. (was it a 8mm movie camera from 1947?)


Look forward to more info and some nice clear pictures.

Surprisingly for a retired electrician, he doesn't. I'll beg, borrow, or buy one before this is all done. I'm curious myself. It's a 300W PSU, which is sufficient overkill to run efficient. We'll see.

I hope he does. Im taking bets its consuming well over 80W. Probably 100-120W.

tl;dr is a lot of what's wrong with modern society. But I'll humour you.

It's a bitfury system, Technobit HEX16B hashing modules times two.

You are correct, I intended to. Oops. Will fix it in a moment.

I don't currently have a Kill-a-watt. My Dad might.

I think a disclosure is needed in your post. Those that followed the AMT thread will know, but others may not, that you were sent this miner for free by AMT in an attempt to prove their legitimacy.  I think its also reasonable to mention that while you received your demo miner, actual paying customers still seem to be waiting for theirs for 6+ weeks now.

As for the machine itself, if you happen to have a kill-a-watt, Im sure many people would be interested in the results. AMT website claims 80W, Im curious if thats true.

tl;dr - is this a bitfury based miner?

Edit/Update February 20th at 5:07 Mountain Time.

Here's a link
to the video I finally got done. Sorry again for taking so long. I'll talk about that a bit in a minute.

Right now, and you'll need to watch the video to see how the pool setup page is, I have a technical question. How the hell do I set up for solo mining with this beast? I want to take a stab at a couple of SHA-256 alts, for fun, profit, and your viewing pleasure. If possible without taking the thing apart and running the boards individually with Hexminer.

As to how long this is taking, I again apologize. My personal situation is ugly. My wife, as of six hours ago, is hospitalized for probably a week. I have a newborn daughter and a seven year old son, and more stress than I can really deal with. I have been a bit snippy with some people on the forum where I try to be measured. If I stepped on any toes, I'm sorry. Due to the constant medical issues, I have had to take a leave from my job to care for my children and wife. For the moment, this miner is my sole source of income. That's not much. Obviously unsustainable, and I'm working on fixing that ASAP, which leaves me little time for keeping current on this, and little incentive to take it off of Eligius, where it's making me something every couple of days. I do believe I can probably do better by mining alts and trading them, but that's a bit difficult right now.

If the above sounds like whining, I'm not prepared to deny the charge. It's been rough. I'll shut up now. The miner works good, at least

Yesterday, AMT was supposed to start delivering the Coincraft based miners. To my knowledge, no one has received tracking info on that yet. I have been very upbeat about this company, because they were good to me and because I like the machine. But if there are no tracking numbers out in the wild in the next couple of days, I'm going to be very disillusioned. AMT, I know you read this thread. Please come through, here. I want you to succeed. But you told me that you wanted me to be objective, and objectively you're not doing so good. Make it right for you paying customers. Even though some of them have gone off the deep end, it's still the right thing to do.

As an aside on that, AMT's business partners in Switzerland are cutting off their own balls with their continued stalling and silence. Come on, vendors, TALK TO YOUR CUSTOMERS. Even when you fuck up. Even when it's bad news. If they are informed and kept in the loop, most will forgive. You can't please everyone, that's an impossible task. But you can keep most of 'em happy by just being honest and informative. Most of us know that shit happens when you're working with bleeding edge technology. Tell us about that shit happening, and you save yourselves ten pages of FUD, easy.

ok, the thing has now been hashing nearly continuously for a bit over a month, totally reliably as near as I can tell. I'm still working on a video. Lots of personal problems at this end.

The "sweet spot" for voltage appears to be 895mv for me. I've gone up and down from that, and got lower average hashrate both ways. It seems to average 83 GH/s local, and around 81 at the pool.

I hope to make a video detailing all the features that I understand (sceenshots and whatnot) later this evening.

My overall impression remains very good. If the quality of this machine is an indicator, AMT is the real deal. They do need to improve their customer relations, but that is true of just about every ASIC company out there, with the possible exception of Bitmain. I want more of these. And bigger

update From here on out I'm going to put any new news or changes to the top of the page, and put in a reply that says OP updated. For those of you into conspiracy theories, get out them screen grabbers! (I will probably delete and reformat as I go along)

This is just a minor update. I've been running the thing on two pools, primarily Eligius, but briefly on BTCguild. Made better money on Eligius, and I really like Whizkid, so I think it unlikely that I'll do much more if any pool exploration while I only have the one machine.

I've done some playing with the voltages, and I get weird results. If I leave it at 900mv, the setting it was delivered with, it is very steady at just above 80 gh/s. If I up the voltage, I get runs where it approaches 90 GH/s, but it's all over the map. Now the weird part. I've been averaging about 83 GH/s with it set to 890mv. I'll tweak a bit further, but so far undervolting has given me better results than overvolting. The "chip frequency" is set to 540, and I haven't touched it. I don't know what it does. Any insights would be helpful on that. I'm going to try dropping the voltage a bit more next, and see where that leads.

Also, while hashing on the guild, Cgminer kept showing four modules with two disabled. A hard reset (power off) put it back, but reboot didn't. Didn't seem to harm anything, and it didn't do it on Eligius. I don't get that. It has two modules. As I said, it's weird, not traumatic. As far as I could tell, it didn't affect the hashrate in any way, it just looked odd.

Money is tight as hell right now, so I'm not tearing the thing down until after the first week in february. When I do, I'll take pictures of every component and post them up in this thread. I may put it in a different case, as I have a good sized one laying around. Then again, I might not


Ok, guys, here it is.

This is a first impressions post of the AMT 80 GH/s miner. It arrived yesterday (1/7/14) at about 6 pm. I wasn't here, so it remained in the box. I posted a video of the unboxing on youtube. I'll edit this post with the link in a bit.

First impression is the thing is bloody small. Then again, it's not very power hungry, so this doesn't seem to be an issue. It's very nice looking in a plain sort of way. I'm a bit of a minimalist anyway, so that appeals to me.

It has an actual powerswitch on the back of the PSU, instead of a softswitch. This too appeals to me.

Enough of that, Kevin, does it hash?

Well, yes, it does. Jim had sent me an email saying to call him to talk me through setup (which I'm still gonna do, since My bashing didn't learn me everything), but I got that email after midnight so I took a stab at it myself.

Bear in mind that I am a noob in the extreme. I've read a lot about these devices, but this is the first one I've ever seen, let alone used. I had to do some research in how to use putty and the like, but I got in, and I figured out how to set up the built in version of cgminer for Eligius. Got that going just a bit ago, and it's happily hashing away.

Here's a link for that, for tonight at least. I intend to experiment with solo mining alt coins in the near future, but right now I don't know what I'm doing well enough to even attempt it.

http://eligius.st/~wizkid057/newstats/userstats.php/1NAivofNXdKhzPvigtWLWMWxYT64huQ8Q

It's hashing around 85 GH/s, so a bit better than advertised. So far my only complaint, and this may not even apply to the units being shipped to real customers, is the lack of documentation. I know very little about linux, so I had to do some searching to figure out how to get into the thing. But I DID do it. The miner works good right out of the box. I suspect that I mined a bit to AMT's account while I was figuring it out, and they're welcome to it.

I'm going to leave it hashing on Eligius for a while, while I sleep at least, and after I talk to the AMT guys and have a better idea what I'm doing, I'll start pushing it's limits. I'll also post video and screenshots for future sessions.

If AMT can deliver these in bulk, I think they are a good entry level miner, and if the big ones work as easily as this one, this is a winning company. They lack polish, but so far I love this machine.

Also, this is a self moderated thread. I'm not into deleting stuff, but if it gets out of hand I will. That being said, I have thick skin and I like to debate, so don't hesitate just because of this. I figured a divergent thread was probably appropriate as things get lost in the noise on the official AMT thread as it is.

Oh, there were some questions asked of me in the other thread.

It is a pair of Technobit HEX16B hashing modules. I haven't popped the case open yet, but I think the on board computer is a raspberry pi. As near as I can tell it's intended to be a standalone unit, but I'm not sure I have it configured properly for that. Not sure I don't either. I'm watching Cgminer in a Putty window. I'll probably shut that down and watch my Eligius page to see if it's still going on it's own in a little bit. I'll update y'all on that.

It runs very quiet. I can hear the fan, but it's not screaming. The case is barely warm to the touch and it's been running for a couple of hours now.

Can't think of anything else right now. Feel free to ask me anything. I'll answer all but the most personal questions as best I can.

EDIT

Puppet is correct, I was sent this unit to evaluate it. I split this off from the main AMT thread, and failed to note that in this thread. No concealment intended. Just an oversight. As the shipping delays, I don't have any knowledge as to what's going on there. Those that say they can't get hold of AMT puzzle me, as I've yet to have any problem, either by email or phone.

EDIT2: Here's the link to the unboxing video. http://www.youtube.com/watch?v=Z-kA5avsZBI&feature=youtu.be
