Def. agree with what was said about trying to get the new rev boards.

On the burnt joints: do the boards have more than 2 layers?  I'm thinking crappy plated vias (now possibly even worse from frying) connecting the internal layers coupled with the ROHS mandated Pb-free solder making for bad connections.

"and still show on amt record as on hold despite numerous <snip>"

That ain't it - they just do not update the account pages. Period. Mine has been "On Hold' since the night I made the order despite them getting my check and it being deposited 4 days later.

Hmm, not sure how I got here.. I *was* on the Official AMT Thread... Do appreciate the need for an order thread though.

Might as well add me to the list.
NotFuzzyWarm   order #1565   Feb. 27, 2014  520GHs    1pc.  Check for $4089(deposited)  expected date "4-weeks" (end of March)   Nope.

Mmm. Here's hoping that lots'o lil elves are hard at work in their PA workshops getting ready to send their majik machines to all the waiting boys and girls...

Somewhere back around the DIY post I do believe AMT also made mention of being caught up (barring PSU's) in 2nd week of April. Coming up mighty quick...

And counter still stuck at 42. Definitely a Douglass Adams thing.

And if you DIY the wiring & sockets, read the package/bin it's in. In the US 120v 20/25A sockets will have one side that has both vertical and a horizontal slot whereas a 'normal size' 220v socket will be one vertical and 1 horizontal (and the horizontal one is on the other side so ya can't stick the wrong voltage plug into the wrong socket). Easy to confuse when looking. Been there, done that...

Hmm, I see my activity counter is stuck again. Been at 42 for several days... HHGTTG thing?

Well for heating cooling needs in common units:
BTU/hr=Watts x 3.4129
1 Tonne=12,000 BTU/hr

so 1,500w is same as 5119.350 BTU/hr heating/cooling or 0.4266 Tonne (cooling units) to be accommodated.

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.

Was gonna say... At home my rate inc all taxes etc. is 15-cents/kWhr and the 4 Ants together are $5.20/day while right now taking in on average 35-45 $/day. several good days recently @ >$65/day. LOVE that pool I'm in Will probably soon move my lil' pharm to out our shop where its only 7-cents kW/hr...

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...

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?

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.

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...

Highly doubt it. The Best Shares I've seen on the best of my Ant s1's (190ghs OC'd) was just over 32milion. That was on an 18hr round

Ant S1 FYI: According to the UPS feeding 2 of them, 1 @ 180GHs the other @ 190 together they pull 739w from the wall. 'Course I run them off of separate 600w PSU's. Keeps the fans on them barely ticking along for nice long life.

+1 ^ ^

Now them fan breakouts will be handy for me Ant pharm! Thanks.

Along those lines.... Those of us with orders for 520's not th-hashers... Hmm since as (now) spec'd it is 200gh/blade (regardless of 'pushed' or not), um so for 520's, what, custom blades with fewer chips? we get 600 instead?

How about if you have blades that won't do the full 200 - but run fine slower - use them for the 520's? Works for me. one caveat: no dead chips allowed. Just happy but slower ones.
