Yep. No they won't.  The logic paths are hard wired to only process the BTC algorithm as given on https://en.bitcoin.it/wiki/Block_hashing_algorithm and cannot be repurposed unlike FPGA's. Then again, being hard wired is what makes them so bloody fast - no intermediate instructions. Is rather like a shift register in how the data flows, in parallel and cascading through with every clock cycle: Read input buffers/move to cores, the result from one operationn is presented to the next while at the same time that next is unloading to it's next or a buffer, CRUNCH - done, write output buffers, rinse and repeat as long as the input buffer has something in it and output has room. 1st run takes several cycles to come out but after that it is non-stop action.

In/out buffer servicing via the SPI link is asynchronous to the ASIC clock. Hopefully the link is fast enough to keep the input buffers filled and the output reasonably empty to take more so there are no dry spells in the data cascade. for ref on the A1 chip, from BMch's repository on Github: https://github.com/bitmine-ch/bitmine/blob/63d22dad5359539a1aa117d4882e71736102581e/Specs/CoinCraft%20A1.pdf?raw=true

Now if you can find some of the older FPGA-based miners on ebay or such you could be in luck. Nearly as fast in cycle efficiency - once programmed for a specific equation/set of operations and that can be sloooow - usually power hungry as well. A few other things factor in as well vs GPU/CUDA ref: http://stackoverflow.com/questions/317731/cuda-vs-fpga All in all, FPGA only really shines in applications where the setup does not change often or needs real-time performance with no wasted cycles.

I only ordered one from AMT but BFL I ordered multiple miners. I don't know which all I will review. I won't talk about late shipping and all that.  Perhaps I set up both 1T miners and check them every day. Make a chart of uptimes etc.

I will do wattage test also since I have a display to show watts and amps.

I want to also compaire against ANT S2 and I am looking into Dragon miners...
good good. where will you be mining them? if you dont mind me asking. as i will be trying alts due to price and diff as is. because it will not make the £26 a day iv calculated it will cost to run btc directly

unless my maths is wildly off. price per unit is roughly 0.19p pkw


 i took a m8s word for the above. wildly out, calculated myself and came out at this £5 a day £30 a month.
Was gonna say... At home my rate inc all taxes etc. is 15-cents/kWhr and the 4 Ants are just over $4/day while right now taking in on average 35-45 $/day. several good days recently @ >$65/day. LOVE that pool I'm in Cheesy Will probably soon move my lil' pharm to out our shop where its only 7-cents...

he worked it out not at 15p a kw but £15 per kw. bet he wont admit it was him tho.
so i will shame him


MELLORBO
looks like i gotta go edit previous posts about the not making power cost

I will do a stand alone evaluation of the AMT box, it should ship next week.
with no bad rating on experienc from the get go. a pure product review??

am i right in thinking bfl chips dont fair well at share sizes but speed in hash is good?

similar to a usb eruptor good spees s**t shares
That will be interesting to see for all the new miners coming out.

My best Ant S1 OC'd to 190ghs over the past 3 days has had exactly 21 raw hardware errors.  Throw in the math for difficulty factors and it is less than 0.01%

Them Ants (but not all of them, the other 3 run up to 10x that @ default 180) set the bar rather high. Damn fine on shares as well. My best so far is over 32 million during a recent hugely long block.

EDIT: Make that 19 raw errors over just under 6 days...

About BFL... they are starting to ship April 14th, they didn't tell the public yet and it hasn't been announced on the forum. They did tell me because let's just say I am a very good customer Smiley My word is good, believe me when I tell you this. If you order one now you get a June delivery.

So they didn't announce nothing to nobody yet man, but believe me they are starting shipping April 14... BFL also gave me over 3 times the hash on some of the miners I ordered. I bought different speed miners from BFL. (Cant say exact details of what exactly I what I bought)

Guys, I am buying miners from every company out there (and continue to do so) and I have my own hosting facilities(more than one). This first round of miners are just a test. I really learned a lot by purchasing one miner from each of the vendors so I know which to recommend now. (I've people waiting to hear on my reviews before they buy miners) I am still hoping AMT can give me proper compensation for the delays I've experienced here.

P.S. I don't ever post on BFL forums, they censor too much there for me. I only talk directly to Paul.


how is blatant advertising none removable and relevant but my comment saying iv read places its a 6+month wait removable?
just asking

I believe I order AMT Dec 13, BFL Nov13.
amt step up! lol he needs yours before bfl lmao.

 do you accept the chalange?

i like the idea of android support so you can just hook up your phone.

I am talking about powering both 5 module units.

300+ GH/s. Thats over 3TH/s.

These modules run great, however the back planes burn out easy, just be careful when powering these.

20A per 5 module unit runs it safe. You need about 200W running nominal and 300W running turbo, atleast thats why my UPS yells at me when I run them in turbo.

You should run 20A because you should never exceed 80% the circuit(like...I am).

~Casey
Are the traces on the backplane green screened or bare? Could always tack solder bus wire along them... Keep the tacks no more that 1" apart. 1/2" is even better. We do that for high pk-current pulsed power systems (>100A in 5-us spikes). Even heavy 10mm wide traces don't like that...

pretty sure someone dropped a '1' from in front of the numbers... as in 1,200-1,300w per-rig perhaps? Wink

so the units draw only 200-300w per 5 card rig? forgive me im not an electrician. a 500w psu could do???

We will see if this AMT miner gets here before my BFL Monarch 1Ts on April 14th Smiley BFL was kind enough to give me extra hash on the miners I ordered (I only ordered 600Gh/s miners). They ALWAYS answer my emails usually less than one hour and know me on a first name basis, and even offered me a full refund but I chose to give them the business and choose the upgrade instead. That's a heads up who bought BFL's its not really known the general public yet. See how well they treat me Smiley
So they've announced that they're ready for/are shipping? Hmm, gonna have to check the BFL Forum on Monarch updates... I'm Trozzlezort there btw, have a couple 10G Jala's as well as me Ants. The 10G's are what got me hooked... And yes, at least on the Forum BFL's Powers-That-Be are very present and talkative.

Is see the 600 is now around $2100.... Dinna pre from them in Feb. because it was clear from the site and especially THEIR FORUM that the Monarch and it's chip were still not-there-yet. Um, unlike Bitmine.ch and...

Hmm, once they get the pre's cleared and start to ship regular orders, gonna have to check them out. Price per gh is pert-near the same as Ants currently are and around 66% less power draw.

I was wrong about the backplane, it works fine...When it has enough power. The last post I made, people need to read, and understand before plugging it into a standard outlet.

I am having my father run a separate line(not good with "electrician stuff") to pull a dedicated AMPERAGE to one outlet.

I would suggest running a 30 AMP breaker, just to be safe and power both Power supplies with turbo mode.


12/13 amps per 5 modules. I am just guestimating, someone can chime in if they'd like(please god chime in, I don't know what I am talking about LOL).


~Casey

30Amp is a lot for one 5 slot miner a 20A is fine, it should fine for 6 slot unit. You will need decent power supplies though. I saw on some pictures a platinum plus 80 unit, they are expensive and very efficient, so they aren't going cheap on power supplies.

anybody got some fancy ideas how to minimize overheads? legal options.

Small Claims Court is super cheap and easy. Max amount is $12k in PA. Biggest cost would be to get to PA for the court date if you lived far away. Once AMT receives the filed court case, I'm sure they would jump at a chance to refund your money immediately. It's a slam dunk case, and they know it.

The THs units aside, still haven't really gotten answer as to what my 520 will be... Now correct me if I'm wrong but, the 80-520 series of miners (still advertised on AMT's site by the way) are the ones that BitMine.ch made/sold at the time I ordered. Sure did lok the same and had same specs. For those, AMT is acting as a reseller for them. BM.ch said they were "sold out", AMT appeared to have them so....

Anywho, with BM.ch now having working boards they have replaced that line with what they call desktop-series http://bitmine.ch/?page_id=893
Note that the 520 has been replaced with 600ghs. Also, that as BMch's compensation for delays, those who ordered the older line direct form them are upgraded to their nearest = or better new version.

Hmm...

Again correct me if im wrong as i admit im not the brightest spark in the world but phinnaeus gage you said

"On to the partial refund aspect. There is no way that AMT can refund you $185 for a PSU that'll cost them $200, for they would be saving $15 on each and every person requesting one per miner ordered. Multiply that several fold and AMT would go broke. Now, imagine if they offered a refund on every part sans 10-15% savings each. They would go broke faster yet, for now we're talking several thousands of dollars of savings on AMT's part, not to mention the extra money they'll make due to shipping less"

Now im not the best at maths so unless im missing something if they are SAVING $15 per psu after a partial refund as u say, how the hell can they go broke? surely they would be making profit on that as they pay you $185 back for what would have been a $200 psu. please correct me if i got that wrong.

You do realize that satire/sarcasm no longer funny if explained. Bottom line, Josh, in no uncertain terms, stated that there would be no refunds due to lack of funds in AMT's coffer, but there is money to purchase full price for and wait for PSUs oppose to shipping kits sans them along with a reasonable rebate, plus save on shipping cost due to the decrease in weight of each package. Josh is playing several ends against the middle, of which one is The Stall Game, his favorite.

Obviously, you don't understand AMT. For every order cancelled, two more were made via professional mining outfits operating hosting facilities.


How do you know this?

Who are they shipping to?
hes a mole!

It was tongue-in-cheek, like the rest of the post, of which morphed into satire/sarcasm.
