I'm trying to setup this program on my VPS, but there is only one port open on these miners. If I forward that port to one of miners I'll only see just that one miner and not the rest. An example would be http://my_ip:4028I'll setup port forwarding in my router but how would I configure the other miners as well? Because the main page comes up real nice on my VPS. Thanks, Michael Port forwarding on the router means that you can choose any port on the outside interface of the router and forward it to an address and port on a machine on the internal interface of the router. So say your external interface on the router is 196.345.67.1 You can have port 1001 on the external interface point to port 4028 on the miner ip 192.168.1.101 i.e. 196.345.67.1:1001 ---> 192.168.1.101:4028 But you can also forward ports 1002, 1003, 1004, 1005 etc to other machines even if they are using the same port i.e. 196.345.67.1:1001 ---> 192.168.1.101:4028 196.345.67.1:1002 ---> 192.168.1.102:4028 196.345.67.1:1003 ---> 192.168.1.103:4028 196.345.67.1:1004 ---> 192.168.1.104:4028 etc Note how the external IP doesn't change, but the port does, and the internal IP does change but the port doesn't Now having explained all this I don't actually think its a real good idea to open up these ports on your router directly to the miner unless you can protect them somehow, at the least by limiting access by IP address. |

From Previous thread: From our chats with datacenter owners, the over 3KW of heat that the SP35 puts out often is too much.
Only if you're not designed for it. We've got a 48U rack running 73.5 kW at our datacenter on pure air cooling with no trouble. It has 15 SP35s and 7 SP30/SP31s. The idea that you have to go to water cooling in order to achieve high densities is both expensive and false. You are correct. It's not that we couldn't do a max density air cooled solution. Spondoolies already does this. It's that our architecture is designed to be upgradeable. Some design concessions had to be made. Water cooling also opens up the hottest parts of the world to mining. We can easily handle 40c+ ambient air temps. And have tested to 70c exiting water temps if so desired for industrial waste heat usage. Higher temps may be possible. With a serial power design this will easily be achievable. -Nathan Can you outline where/how the radiators fit into the setup? I imagine they are external, so is the unit really a 1U unit or is it 1U plus radiator? Also could you outline what your expected performance output will be per unit? An idea of price would be good too  As suggested already, best to open up a new thread with your details/announcement. |

Thanks for the images. We do have a restriction on the width in which the grid mode will display, this is probably what you're referring to. We'll take a look at how we can address this issue You can make the window smaller in the browser if you zoom out using the browser feature. (tested using Chrome) But maybe what is needed is just a more concise view with less info. |

To be fair, depends on the datacenter owners they have been talking to, if they are traditional hot/cold aisle airconned DC's then they have a point, yours, awesome as it is, is pretty specifically designed and build for mining hardware. |

Prove you are not a Ponzi by posting pics of the mining farm you have built that will do the mining shares that people buy.
Make sure the pics are of your own kit that you purchased to start this business and that they have some sort of proof such a printed card held by someone with the date on it and message to this forum or a loaf of bread or something verifyable.

We also want to future proof our cooling system. Going with more than 2U gives us extra headroom on cooling. Who knows what the thermal density of the next ASIC will be? 3-4U also allows us 120mm fans which are more energy efficient and quieter.
Power supplies will be internal, included, and upgradeable via a new PDB(power distribution board). (see above photos)
-Nathan
Dayum.. although I do get the 120mm fan concept, not sure about quietness, its in a datacenter right? Who cares how loud it is. For me, only way I would justify a 4U box would be if it was 2x as powerful as a 2U box. But if you can get 6TH or more out of a watercooled 1U box then thats fine for me |

We are also working on a 3-4U air cooled version of the above tray. Everything identical except with air cooled heat pipe heatsink below, and fans.
Hi Nathan, Is it worth trying for a 2U version? For rackmount datacenter centric kit like this noise isn't an issue so pack it full of fans 2U is also a great rack density effective form factor for air cooled rigs. Otherwise the 1U would be my poison. Are the psu's going to be included and internal to the chassis? |

Thats a rebadged scrypt miner, nothing to do with the question which is about a non existent SHA256 miner.  |
|

Hello guys,
First reply from me here, and thank you all for the support and tips provided all over the forum.
I am planning to pre order this SHA 256 mining machine (Uranus Miner), and the company replied to the order and mentioned that they did not accept PayPal neither credit cards for the time being according to a technical issues, however, they accept bitcoins and bank wire transfer only.
So can I trust this company and send the money in advance without knowing if they really will ship the item I pre ordered it or not?
Expert advice please who dealt with this company before and received their machines already with trust.
Plain answer, No you can't. Only send them money that you can afford to never see again. They basically made a couple of Apollo machines which were just Hashfast boards screwed into a PC case, one of which they sent to dogie for review. The rest of their sales are just rebadged Scrypt Litecoin mining machines from another company. The Uranus (lol) is vaporware, the only 20nm mining chip ever made came from KnC and that monster, well no-one else bothered because its not worth it. Plus they have 5 days to deliver it on time to hit their Q1 deadline. Basically only buy from stock or once someone has proven that something exists. |

Where you see the downtime calculations (Lee`s site)?
In Mr Lee's portal. Best to get him to send you the link and set you up with a login and password |

I understand what you are saying and it is perfectly fair, but I said "why not also manufacture in Europe or China"
If you can't sell into Europe or elsewhere because of taxes or delivery charges then you lose nothing by also manufacturing elsewhere.
However, I applaud what you are doing. Bitmain's U3 device used items that the home miner could easily source for themselves making it uneconomic to ship. Do what you do best of all.
Delivery costs from the US shouldn't be too bad. What happens in Europe is you get hit with VAT as there isn't any duty. But its a misnomer to think you can get miners "Tax Free" by assembly or manufacture in Europe, whoever sells it still has to charge VAT on top. |

I have finally bought one 256 mh/s Alcheminer at 999$. What kind of power supply do i need ? it take one or two PSU? Is it possible to mine on wifi ? Sorry, im a beginner in mining stuff
This is the bitcoin forum, you need to ask your questions about mining alt-coins in the appropriate forum https://bitcointalk.org/index.php?board=160.0. The machine you purchased won't mine Bitcoins. |

I don't like leaving a PC on 24/7 when not necessary. Being in the IT/Tech field I know better than that.  Also saves on electricity.  Now onto my original question : Not looking for the jumper trick to keep a standalone PS running.
What I'm looking for is to keep a Power supply running on a miner, while the PC which is also running off the same power supply, is shut down.
I want to power a PC and miner from the same PS, but if the PC is shut down, I need the PS to be on for the miner to still run.
Any ideas?Not getting into a comprehension contest here, but where do I say I want the power supply to be on and off at the same time? If you read carefully, you'd notice I said to keep the PS <ON>, even though the PC which is running off the same power supply is <OFF>. Never saying anywhere I want the power supply to be ON and OFF at the same time. Now please, unless you have an idea or way to do this, move on. This was a question about finding a possible solution to my needs, not about why I want to do it. Thank you. Sorry but your second question and the rest of your post turn what you have written into an oxymoron. |

If you are tackling sellers, not just manufacturers, how about CrazyGuy and ASICPuppy.net they seem pretty reputable reseller.

Hi Lee
The Bitmain price is back down to $340 are you going to change the OP and topic title to reflect this or are you sticking with $419?
|

You cannot have a psu that is both on and off at the same time, you're asking something that doesn't make sense.
LOL. Never said I want it to be on and off at the same time.  Why would you shut down a PC anyway? Just put it on standby or low power mode. PSU should still provide some juice to keep a miner going. |

can we have one or all three blocks before new diff. arrives Please
Too late  At least it went down |

Why Hammer? Is Rockerbox too demanding?
Hammer:
Rated HashRate 7.5 GH/s per chip
Rated Voltage 0.63 V, recommended voltage range is 0.6 V - 0.8 V
Power Consumption 0.58 W/GH/s
Rockerbox:
Rated hash rate: 200 GH/s per chip
Rated Voltage 0.7 V, recommended voltage range is 0.63 V - 0.8 V
Power Consumption 0.34 W/GHs in typical corner
Doh.. your talking about USB sticks... 200 x 0.34W is too much |
