One thing I'll add. I am pretty sure I saw that the chips would sell for roughly $30 each. That would put the parts cost for this in at least the $70-80 range (wild guess on my part). Maybe j4bberwock got a better price, but I don't think anybody should expect this to be cheap.
Final retail price will be close to $150. You are right on the price of the chips, you can't get them really cheaper. Then, you add the PCB, the other components, and the cost of the assembly. To be transparent, they will cost me at least $125 including import taxes and VAT. And we are speaking of a bulk order of over 1000 boards. J4bberwock, which software will support these miners? Will cgminer or bfgminer devs add support for these devices, or is ancient minerd (the one that is also used for SFARDS official miner) the only one that is going to be supported? It will be minerd initially, but the driver code is structured quit well so I might be adding bfgminer support pretty quickly. |

So besides the Zoomhash website, is there any other place to buy these miners at a more fair price?
Not aware of them in any USA seller other then Zoomhash. And like everyone else I have not seen a photo of one in action. Here is one in "action"   |

I am looking to buy an Antminer S5 or possibly an S3 depending on the price on both, I am located in the continental US and will only pay BTC, let me know your offers. Thanks!
Hey I have two S5s I can sell you. They also have the 3D printed cooling mods on them so they run super quiet. Have stock fans as well. 350 each. |

too bad that are horribly inefficient. Pretty much 1W/GH

I am an aerospace engineer.I know what they are technically capable of and not.It is not about money, it is just not ethical.
How is this not ethical?? You could be running the S5s in a bad environment with not adequate cooling with boards hashing at 100C. You want bitmain to just keep sending you free boards because your farm is not setup right? They have the right to check the boards to see what is causing the issue, and its pretty easy to confirm that the boards were overheated etc. |

You can add wifi to any miner you want...just use a wifi router as a bridge...or for just $40 buy a rasberry pi with a USB wifi dongle.

Final specs and price: The miner is 1.72T sha-256, 54M scrypt, 970W power consumption. The price is RMB 8000 Yuan, namely 1290 USD. Way overpriced for a miner that will produce a total of ~ 100-150USD profit after power cost and litecoin halving. Would take nearly a year to ROI lol. Even at half the price it would barely be worth it. |

I guess we will switch to the Avalon Mini. Hope the price will be good.  Yea sorry guys this is not happening so I'm just going to close it out. Never got a response from them for the used units. |

I have a bunch make me an offer...dont think ill let these go cheap though LTC is 8 bucks and going.
|
|
|
|
7 bucks and going lol, if I don't get any offers soon I will turn these back on myself...LTC is finally going to the mooooon These are now making more profit than an antminer S5 for the same power. |
|
|
|
Anything think this company is pushing the price of LTC/BTC to increase sales of this miner?
No idea why the price basically more then tripled in the last month.
It would take many millions to push the price by one company to the point it is at now (probably 10s of millions). They probably invested a fraction of that to develop these chips. |
|

NYC...litecoin is nearly 6 bucks and this rally is not stopping any time soon, don't miss out on the very few scrypt asic available when LTC is 10+  And for people not familiar with litecoin, these are currently exactly equivalent to an Antminer S5, they draw that same amount of power and make the equivalent LTC that an S5 makes in BTC. |
|

Example:
BTC:
sudo ./minerd -a sha256d -o stratum+tcp://POOL_URL -u USER -p PASSWORD -d /dev/ttyUSBx -f 600
LTC
sudo ./minerd -o stratum+tcp://POOL_URL -u USER -p PASSWORD -d /dev/ttyUSBx -f 600
So just like the original gridseeds you will be running two separate instances of the mining software (one for BTC and one for LTC). Each can be tuned individually. Like J4bberwock said; it shouldn't be long before someone adds support to cgminer. No one ever managed (AFAIK) to get separate instances of cgminer to run both BTC and LTC at the same time with the original gridseeds. You could only run cgminer for BTC and then had to run cpuminer for LTC when dual mining. Trying to run cgminer with gridseed scrypt support at the same time as cgminer with gridseed sha256 support would not work. The second instance of cgminer would see the port as already in use (I think...it's been a while). One instance of cgminer utilizing both SHA256 and scrypt would be ideal but something tells me we wont see that unless Sfards changed the way the miners are accessed. There was some talk of it being worked on by third parties (with the original gridseeds) but nothing came of it. Huh, hopefully they will implement driver into cgminer and bfgminer as soon as possible since the original minerd is a rather ancient piece of software ...
I wouldn't count on it. They will most likely only release what is already available and count on others to fill in the gaps like they did with the original gridseeds. Not sure how the original grid seeds were engineered, but these have completely separated power buses and two com channels one for BTC cores and one for LTC...its one chip but everything is chained completely separate. The final hardware on these will have two separate USB to serial ports, so it should be no issue configuring two seprate instances of cgminer/bfgminer...one to point to the BTC coms and one pointing to LTC coms. |

bumpy LTC to $4 and still going!

I can confirm this issue on my units as well...I have the fans connected directly to power though, but heat still insane. I think the chips are still powered but not hashing, so they are essentially 100% heaters.
This is a huge firmware/design flaw...not sure why bitmain has not fixed it yet...

I ran my zeus scrypt miners outside for months last summer...never had a single problem (they were sitting outside underneath my roofed porch)...they made way to much noise to attract any animals and my house is pretty isolated so no issues from thieves. Had some dust buildup but thats about it...survived through heat, torrential downpours, etc.
Miners are rather simple devices, as long as the cooling is not clogged and water does not directly touch the components they'll be fine.

Ok so latest from Avalon is that they are completely sold out of new units, but have used units to sell. If people don't care that they are used I will try and negotiate a price for used.

Its two boards at 12 chips each board....what they want to charge for this won't make it viable for a home miner Ill tell you that much.

What degree difference does it seem to make having that on them? Also you might look into the 3d and other mods to close the top of your going to that much work on bottom.
closing the top of s-5's is a bad idea. closing the bottom is a good idea. at least my tests have shown me that: a closed bottom helps and a closed top and bottom does not help. I wanted to send him one of my fans since it is a large fan and would generate more air across the bottom heatsink he attached. My guess is the only improvement to his idea is getting some air on that bottom heat sink. For air cooling my guess is his idea of that bottom heatsink is really good. Have you tested the 3d set or what did you test to close it? Did you test a vertical setup? I think they also have been putting them vertical with the 3d ones which would make a big difference on heat direction with a vertical orientation. I would love to see some of your testing if you don't mind posting  . I did 1 unit vertical and decided to not document it since I knew I would not run a lot of s-5's. I found on a push pull setup air leaks at the bottom and the top of the unit. but the top air leak does 2 things it runs air directly at the temp sensors and at the controller. if you fully cover an s-5 and use push pull fans the air that cools the controller/temp sensors is redirected out of the pull fan. so it does not work so good. if you fully seal the bottom which I did with a temp resistant rubber pad no air leaks out the bottom. so that air runs upwards and at the pull fan. so the temp sensors get more air and the pull fan gets more air. thus it cools better. this setup by the op looks really good maybe the best air cooled s-5 I have seen. if he just had a little more fan action on that added heatsink it would be great. You do understand that just because more air is running over the temp sensor does not mean its running "better" or "cooler." Running air through the sides (opposite the heatsink) does absolutely nothing in cooling the actual ASIC chips, which is what we care about. All this does it lower the temp of the temp sensor, which just gives a lower non accurate temperature reading. Closing the top and bottom is the best way to direct the maximum amount of airflow over the heatsinks, which is the only thing that cools the chips. This will also give a more accurate sensor reading as well. |
