Is this a Bitmain thread :p ...so back on topic...wth is going on with Bitfury? They have added zero hash, and this chip is nowhere to be seen...which makes me think they are having major issues with the production version of the chip/immersion board.

would it be possible to post a link to the now inaccessible contents of the most helpful thread over at litecointalk, concerning fine tuning and command parameters for the Moonlanders?
thanks in advance,
deeneendo
its posted in the main thread on here...check out the second post here: https://bitcointalk.org/index.php?topic=1248914.0 |

I believe my HUB isn't performing to what it says. I got the superbpag USB 3.0 Superspeed HUB, http://www.amazon.com/gp/product/B00W4X3DAA?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00, and when I plug a moonlander in, it wont read on bfgminer. My computer will give the error "usb device not recognized the item has malfunctioned", I thought I received a destroyed miner, but when I connected my other two, it gave me the same error. I connected the miners directly into the computer and they all work. Yet I'm having an issue of the speeds slowly decreasing and bfgminer 5.4 declaring it "SICK. Does anyone know how I can fix this? Should I increase the intensity? Also to get multiple miners working at one time, should I run two instances of bfgminer each with its own config or can I put in the config to use two login information? This is the hub I recommend. http://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM/ref=pd_sim_sbs_147_1?ie=UTF8&dpID=41LaxmqTREL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0FW4KH14FP92J3MHA2XFIt has an internal really well constructed Powersupply, and is the only hub I found that can handle all 7 ports running full speed. The on you linked probably has an external crappy brick PSU which is probably not good enough. For the "Sick" issue it probably means you have the difficulty set too high...so it takes forever for the stick to submit a share, so bfgminer "thinks" its sick. Remember these are low powered devices and most pools think you are connecting high speed ASICs to them and have stock high difficulties. Make sure you are using vardiff with low initial diff, or forcing a diff of under 100. 16 diff per stick is a good starting point. This will give a share every second or so. |

Putting one of my units up for sale. I am the dev of all the firmware/bfgminer ports for this device, so it has the latest firmware on all 8 hashboards, and runs the latest version of bfgminer. Stock these units did about 200MH, with my upgrades they do ~240, and work on all pools.
These have been selling for around 1800-1900 on eBay...can do a bit lower but don't lowball me :p
Location? and iys a bad idea to compare this place to ebay. ebay is for idiots and scammers on here you get the true value no some imagined value so dont get your hopes up of getting ebay prives In NY...and I beg to differ, I've already sold a few of these for the same price. The same people that are on here buy on eBay when they DONT want scammers, since both buyers and sellers are protected. If anything all the scammers and lowballers are here. The only difference with eBay is that price is obviously inflated by 10% or so since sellers need to cover fees. |

No uses about 2kw at the wall. I'm using a 1300 ATX and 800 watt server PSU to power it.

So you bought an over 5k miner...and just left it in the box and never used it? Lol come on man come up with something more believable when your outright lying...

which coins i can mine with this scrypt miner?
more than ltc or doge?
scrypt is also x11 as example - correct?
scrypt and x11 are different algorithms..this mines only scrypt coins. Hmmmh, thanks. But scrypt is not profitable  People use this mostly as cheap little lottery miners. They cost next to nothing to run, and you have a chance of making about $100 if you get lucky  |

Yes still have some left, just follow the instructions in this thread or send me a PM.

Sorry guys I haven't checked this thread in a while. Litecointalk got hacked and its still down, I'm going to take all the info from the support thread and either post it in the beginning in this thread or make a new support thread here. BTW I got batch 2 in, so people that did not order from original batch have one last chance to order. I can ship them out immediately! Just check out the order thread here for instructions etc. https://bitcointalk.org/index.php?topic=1256818.0 |

Just finished up a smaller batch 2 for people that didn't get a chance to order batch 1. Stick are available to ship immediately, and since this batch is a no risk and no pre-order (plus pricing went up on everything since it was a smaller batch) price will be $39 + shipping this round.
Payment instructions and the like are the same, so please follow the instructions on the first post. Limit 4 sticks per person this time so more people have access to them!

Say, got a question. Who's the best domestic quick-turn prototype PCB fab? We've gotten prototype PCBs made by SEEED, but they're in China - which is grating for obvious patriotic reasons and because it makes shipping suck for any kind of speed.
I use http://www.pcbunlimited.comTheir Panel share is ridiculously cheap for prototyping if you can wait 5 days, but their quick turn is not too bad either. |

I've been playing around with a few moonlanders this weekend and they run much better on the cubieboard. Could be that they have an extra 512mb of memory, as well as the fact that they recognize my 10 port anker hub just fine. The custom minera image I've built will be shipped with all cubieboard orders. 5 Moonlanders at base clock(144mhz) connected to cubieboard.  Nice job on the custom minera interface...looks awesome |

I would assume they are releasing the board info so engis and small companies can prep designs to incorporate their 16nm chip....
They haven't released anything...those are just pretty pictures to look at. From an engineering standpoint you need detailed datasheets, pinouts, and IC footprints at minimum to begin laying out a board. Maybe you can get a crude schematic together with the info they have released but thats about it. |

My guess is that the 'snakey' lines are parallel coms of some sort and the bendy bits are to make sure the traces are the same length so signal propagation times are the same on all lines. Also note the lack of 90-deg corners aside from in the bendy bits. With 90-deg corners a trace is wider across the diagonal of the corner and that creates an impedance disruption in the transmission line at those points.
Yes if you see any "snake" type traces its because they are parallel IO traces to some other longer traces, so they need to make the traces the same lengths hence the snakes. If you check out your PC motherboard you'll see them all over the place on the PCIe and RAM lanes. When your talking about throughputs in the muti Gigabits/s even the speed of light works against you This does not matter on anything bitcoin related though, since these are very dumb chips IO rates coming to/from them are in the order of sub 1Mb/s, since nothing larger than a couple hundred bytes is ever sent to the chips( and return IO is even less...just an 8 byte nonce return and maybe a few bytes of chip info data). |

Well if these guys have millions to spend you'd figure they have a least one marketing guy to write up a post longer than 5 lines...and maybe figure out how to put up a legit looking website...

I love how some random guy can come on here and post 5 lines about some vaporware, then get endorsed by bitfury, and people like sidehack and I, which have produced miners and have the support of the community can't even get access to a datasheet to make some miners bitfury knows we can make and will sell in the thousands.
Do these companies just love promoting scammers and companies that will end up screwing over the home miners once again?

Looking really good guys, very excited for you!
This is a question for buysolar, if one were to do a PV setup that wasn't grid tied (I guess you would need batteries to buffer) and mining continuously with it, would it be possible to keep voltage produced in DC and regulate to 12V to prevent inefficiencies from inverters and then again from power supplies?
No, the wire losses would be greater than any inverter inefficiencies, plus you would need ALOT of copper. You have to remember even in a 150w 12v panel you looking at 12.5 Amps of current. 60kw would need copper that can support 5 THOUSAND AMPS of current lol...ill let you do the math on the copper thickness you need for that This is why most solar setups are wired in series, and some have muti kilovolts running into their main inverters, or simply have an 120v inverter directly on the panel. |
