This is the CGminer that I use with my Zeus miners. When you compile it, enable options scrypt and Zeus. This is an updated version and has extra-nonce subscription built in. I bet it works equally well with the farm boys. https://github.com/dmaxl/cgminerI doubt that. Even though they share the exact same UART coms the zeus chips and A2 chips on these are completely different. The serial commands needed to prepare the chips and send work to them are most likely not the same. Im sure there is the source code for the A2's somewhere that could be easily ported over to newer version of CGminer/bfgminer. |

QA by Innosilicon, this batch of 60Mhs units are contract manufactured by previous Zeus manufacturer and can be used to directly replace Zesu if you own one since all non-PCB parts such as PSU, fans, cases, router, heat-sink is pretty much reusable from old Zeus miners. Note that PSU is external just like Zesu and any open market PC power supply (600W or above power supply with PCIe6+2 connector) will do it. The case and heat sink from new machines are reused from Zesu miners but QA qualified and don’t affect the performance. If you own a old Zesu, you can reuse all the parts except PCB as spares. If you want to buy our 110Mhs A2 Power Terminator unit with PSU in the case, the price now is 1K US per Unit.
Nevermind...guess I should have read their whole post  |

Very interesting! Someone at Innosilicon spent some time designing a new PCB for that form factor. Once again impressed with Innosilicon.
If only I had more power available I would be looking at some Farm Boys or some more A2 Mega Terminators. The comments from Toomim Brothers on the steel used for the Terminators is accurate. They are built like a tank...unnecessarily so.
I too think they should offer the A2 Mega Terminators without power supplies but due to their overly heavy construction I doubt it would save much on shipping.
Actually no....whats interesting about this design is that its and EXACT copy of Zeusminer hardware. It uses the same case design, exact same heatsinks, and even the power rails / design on the PCBs are an exact copy from the zeus board designs. If you look closely even the screw holes are in the same position. (this would be interesting for people that have zeus hardware and want to upgrade buy ordering just the blades). Pretty sure whoever is behind these new machines are whats left of the Zeus miner team (or Zeus Miner was simply a rebrand of early Inso tech).   |

UPDATE: Finished bfgminer port for these....between this and fpga firmware update they run full speed on almost any scrypt pool! PM me for details I have been working on a big update to the Alcheminer / MAT excalibur over on litecointalk (I won't repost the whole thing here but you can read up here : https://litecointalk.org/index.php?topic=27370.0Long story short I found a huge flaw in the FPGA firmware that drives these machines, and updated the FPGA code as well as the python driver code to support the new logic. I have the machines running at full speed (around 250MH up from stock firmware/driver of around 210-220) at around 8W/MH. There are also a lot more driver updates including the ability to change clock rate and tweaks to the stratum proxy. Now that I have had a few users test out the firmware and upgrade process I'm posting it on here in case anyone with these machines has not seen the liitecointalk discussion and wants to get a bit more performance out of these. Shoot me a PM on here or litecointalk for more info! (same username). |

I hope sfards makes some new miners soon before the LTC hashrate goes into the shitter.
I hear that, need something cheaper to keep the hashrate up on these coins. Hashrate barely dropped 15% post halving, and its already stabilized...I was hoping for at least a 20-30% drop... |

Yeah that's it. I remember thinking that corrugated cardboard makes terrible heatsinks.
Lol please tell me thats a joke....Chips on their boards don't even have heatsinks...I don't know whats worse. |

I recently shipped my SFARDS to a fellow forum member who will be doing a full tear down and write up on it for the community. When he is done he will ship the miner back to me so stand by for more info on the ins and outs of the hardware and the software interface
I agree I think most units produced went for internal use or a private buyer they probably shipped a hand full to resellers just to prove the miner is real but at its efficiency they didn't do a public release since they are the highest in efficiency for both SHA256 and almost in scrpyt right now I think Titans still are higher
Nope they beat Titans for scrypt efficiency by a wide margin. Last I checked titans were around 5-6 W/MH, these do a little over 2 W/MH |

Anyone? I am at a loss here.
Just make yourself one...all you need is 3 jumper wires. |

Yea with 200 BTC and $3 LTC (equivalent of $1.5 after that halving tomorrow, which is the same it was pre pump) things are not looking too good for any sort of mining in general.

Will wait for the price to adjust to market. One way or the other prices will be coming down
Yep...you have to remember gridseed blades (SFARDS is rebranded Gridseed) sold them for like 3k initially, prices then plummeted to under 1k each few months later. The less people pay for these overpriced miners the faster the price will drop. |

BITMAIN please offer the option to split this into 1/3 miner with these specs: 2.6TH@1150 watts for about 800 USD.
Is very easily doable with the design of this since its essentially 3 miners stuck together.

Looking at the pics/specs its obvious they can make an S5 sized unit with this hardware. The specs for that would be 2.6TH@1150 watts for about 800 USD.
I hope they go this route as that would be a way more manageable home miner.

I guess quite a few of us have spent a lot of time testing and experimenting and then waiting for the Hash rate to stabilise to then log the GH/s?
It struck me while doing this that for a system that is working correctly surely there ought to be a direct relationship between Clock Frequency and GH/s?
So I looked back on the data sheets and measurements that I had made and came up with the following.
The S3+ (BM1382) seems very straightforward and if you multiply the Clock Frequency by 2 then you get the hash in GH/s. So the spec of 225MHz = 453GH/s. In my testing this was confirmed over a range of frequencies.
So when I started work with an S5 () I looked for something similar and it seemed to come to Clock Frequency x 3.3 = Hash in GH/s. So 355Mhz x 3.3 = 1150GH/s which is the spec of the S5, again this is borne out by the testing I have done over a range of frequencies & voltages.
In practice i have found the longer I wait for the Hash to stabilise the closer it get to the calculated value. So I wonder if we are we are wasting our time, for a system that is functioning correctly, waiting for Hash rates to stabilise as opposed to just doing some maths? Answers on a postcard to….
Rich
You are correct, the cores take a certain number of clock cycles to produce a single hash, so clock to hash rate can always be calculated from multiple factor of the clock frequency with a very high degree of accuracy. The only thing that affects this is as you go higher in frequency heat/logical core failures will increase and slightly drop the hash rate. |

I will also most likely be doing USA sales for these. Im located in NY so US shipments will be cheapest through me.

Wow, very efficient miner indeed  Can you prove your website is legitimate, your account is new. Read the thread in its entirity ... the man has been made to jump through a thousand hoops already! But 28 6pin PCI-E connectors for a single rig is mind boggling to say the least. Is the 6 pin PCI-E connector the highest rated power plug that exists? 8 pin is rated at 150W officially, but for our use won't double whatever number each of us is comfortable with on 6 pin as it only adds 2 more ground wires. not to mention no home outlet will support 3400 watts.. so it would have to be specially wired in its own sub panel. and this thing looks like a fire hazard..
No? You can power it from up to 9 PSUs if you want and split what circuits the PSUs are on as you like. so i just run extension cords to different outlets? lol If they were on different circuits, pretty much. I've got 2x 32A and 2x 20A circuits (all 240v) extension-ed into one room so I can test some pretty large things if required. What? You could run this whole thing from a single 240v socket....its 14amps at the voltage, would run comfortably even on the 20A circuit And you could easily run a single PCI to each hashboard, if you have a server style PSU with breakout boards...its all about running the proper gauge wiring. |

the names are not the same - they change some characters so it looks the same at first sight.
yea they added a 'r' right after the a in my name...bastards |

Russian proverb says of the cat
I picked SF 100 to the office of my company in China and sent to Russia, will make a full report on its work in a few days.
Dont listen to all the trolls on this forum. Look forward to see your report...would love to see pool side specs over 24 hours of both LTC and BTC side, as well as power draw at the wall. Thanks! |
