Nice write-up (as always), your antminer guide is, well, legendary.
(On a separate note, why are manufacturers still making usb miners?)
Thanks  USBs fit with the message of bitcoin which is decentralisation. Imagine if there were no larger miners, only usbs. You could only have a few per person without hubs, so the network would be extremely spread out. The same message applies even with the network size as it is. Plus they look cool and make good gifts/learning aids. |

Dogie's Miner Setup Guides:Nicely formatted version available at dogiecoin.com!  Contents: 0a) What to Expect0b) What You Need1) Powering2) Cooling3a) Configuration3b) Overclocking (optional)4) Troubleshooting5) Where to buy0a) What to Expect (top)The NanoFury II board is designed by vs3 and features 2 Bitfury chips. It ships in a USPS cardboard sleeve and is wrapped in both copious amounts of bubble wrap and static paper. | Chips | 2x Bitfury gen2 | | Hashrate | ~4GH stock, ~5GH OC'ed | | Rated Voltage | 5V | | Rated Current | 0.9A at stock, up to 1.9A OC'ed | | Power.Consumption | 4.5-9.5W |
   0b) What You Need (top)You will need the following: - A host windows PC.
- A 1A+ USB hub (see below).
1) Powering (top)NanoFury IIs are USB based miners, and as such are powered directly from a USB hub. Hub choice is extremely important when running multiple miners, although external power is not required. The USB2 specification is designed to provide up to 0.5A, USB3 0.9A and so USB3 is strongly recommended. - Plug in the USB hub's power adapter into the mains and the USB hub.
- Plug the NanoFury II into USB hub.
USB 3 Hub:

    2) Cooling (top)External cooling is not strictly required at stock speeds, but is strongly recommended any higher than 4GH. This can be done with the use of a simple 120mm fan or a USB powered fan. Please be careful when handling this heatsink as the fins are very thin and so extremely sharp. 120mm Fans:

3a) Configuration (top)Configuration is straight forward. Both BFG and CGMiner are currently supported and a Windows based PC is therefore recommended. BFGMiner: - Plug in a USB cable from your USB hub to your PC.
- Power the NanoFury II as above and turn the hub on.
- No drivers need to be installed.
- Download BFGMiner and run it.
- Create a new text file using notepad, with your pool and miner information in it, as below. Save it as a .bat file in the same directory as BFGMiner.
- Run the bat file to start mining.
- It may take up to 5 minutes for 3.7-4GH to be achieved.
If you want to change pool, create a .bat file in notepad. Move the stratum proxy to the location below and put the following text inside for different pools. Change pool port and address for different pools. Antpool Register!bfgminer.exe -o stratum.antpool.com:3333 -u username_worker -p anypassword bfgminer.exe -o stratum.btcguild.com:3333 -u username_worker -p anypassword bfgminer.exe -o us1.ghash.io:3333 -u username_worker -p anypassword Overclocking is required in order to hit 5GH. - Press M to manage devices.
- Press O to enter a new oscillator bit rate.
- 50 is default, 53 is standard OCing, 55-56 is tested cap. Do NOT exceed this. Press enter to submit the change.
- Each chip is controlled separately, so press down to see the second chip and repeat.
- Pressing D and then Z clears the stats so you can see the changes quicker.
- If you have set the oscillator too high then the hardware % will rise above 5% and the chip will be reset often. If this is the case, lower the rate. Chip b
will likely max out 1 bit below chip a.

Dogie, maybe include lketc.com also?
They don't target their business towards the NA/EU almost at all. Consequently, the consumers don't target them. They'll be added if this changes. |

Nothing wrong with that, you often need 5-10 machines to properly test firmware with several variations, clock speeds and pools. Dogie, do you plan on ordering one of the "Prospector" units from VMC for an independent review?
They are simply boards created by using the same reference design for a REV 2 that HashFast gives out to anyone that orders chips from them.
I believe Ken also confirmed that they are using the same Fab that HashFast used to make their boards.
Depending on which side of the fence you are (Pro or Negative VMC) you would say these are just resold boards or believe what Ken is saying.
I believe they are buying parts but the stickers on the boards were a little strange. Might just be what the fab is used to doing though. Up to you to decide if that is relevant.
You do have great guides so if you do purchase one we can compare notes. There's a strange bug when having both fo the units plugged in that crashes CGMiner and keeps saying "Main Board 12V Bad". Just have to reset them and try again until it works. Also noticed that CGMiner crashes with these quite a bit. I'm working with Luke to test out BFGMiner on them as well. I'm using a windows computer and from what I heard linux is much more stable for these boards.
At this moment I don't, because they're 'known' and you've covered most of the setup help required. There shouldn't be any surprises with them, and the software issues will be resolved once the devs get hardware. You'll start to see a lot more cross licensing in 2014 as it becomes more common practice. VMC is still yet to prove their own silicon though. Ps, try a Linux virtual PC then |

but the plug that I have running of 2 4 pin molex those wires are nice and cool
What does "2 4 pin molex" mean? The cube has two 6-pin power connectors. Each should have six wires. which leads me to believe that the stock fuse was the cause of my issues, It was forcing more current draw due to the resistance of the metal that was used in it....hence the hotter wires...
He means 2xmolex to 1xPCI-E cable |

Thank you for the exellent guide. I figured out that "http://" in the bitminter pool address was the cause of my headaches when playing around with the stratum proxy.
That would do it. Pool addresses aren't http based so it would cause an error. I'm getting about 7.5-8 Mhs from both blades but one of them seems to have two x:es.. Could the slow hashrate be due to the Via C7 struggling with Stratum? (Via C7@1Ghz, 1Gb DDR2 and 60Gb SSD). I'll try to post a screenie Look at your CPU usage, maybe. Try turning one blade off and seeing if the other's goes up. You may also be power limited if two Xs are up. Cpu usage on the Via box is at 100% :/ Turning off bitminter didn't help... So yes, that's your limiter. |

Mining will be dead by June.
Hashrate will be 15 Billion. By September it will cost more in electricity to run than the btc it mines.
2TH miner will make less than $950 lifetime if BTC stays under $500
Mining will never die bro True, but they wont be profitable anymore. Then difficulty will stagnate. |

As I've said 15x, if what you're saying is true then sue them. But its probably not, so you won't.

I pulled the cube apart, inspected and tightened the heat sink screws (just a little). I swapped board 4 for board 6 (only the first 3 boards were hashing).
It's back online at LOW clock. The first 3 boards are hashing well and board 4 has a few chips that are hashing and they are doing poorly, board 5 and 6 are all zeros for hashing but no boards are showing up as dead Xs.
Total hashing rate is 12,599.
I have to admit that my two cubes have been nothing but problems since day one. Nice concept and good form factor but problems on the inside.
Remove any board which isnt working! It will only cause more damage if its dead. |

Stop doing the same thing! Either put content here or dont post, but there's no point posting a topic with a hyperlink to your own content elsewhere.

They're hot as hell - if the temp sensor layout is the same as Avalon1. But if its both, check network stuff.

After experiencing weeks of one of my two cubes shutting down for no apparent reason (sometimes it would run from 15 minutes to 2 days) I broke out the soldering iron last night and jumped those two solder points. The problematic cube has been hashing away without any issues for 16 hours and 18 minutes. This appears to have solved the problem of it dropping out (just the top green light on).
I don't have any Android appliances and I did try different power supplies, move the cubes to different locations in the house and garage, changing the IP address, pulling and re-seating boards, updated the mining_proxy software, etc. Nothing worked for long.
Now if I could only get my one cube running back around 30Gh/s instead of the 12-15Gh/s range. It used to work okay (nothing better than 30Gh/s). I wonder if I should break out the soldering iron and jumper it? Comments?
thanks
What were the results of swapping the problem cube with the exact position and power of the other cube? |

AFAIK they chose to not release their new gen - it didn't turn out as well as it could have. They're waiting until they can deliver something perfect.
Which are you referring to? The 55nm(?) one that didn't perform, or the 3rd gen 40nm that just recently came out of the fab and (functionally) tested okay? 55nm. The 40 should be moderately good however its about 6 weeks behind where they'd have preferred it to be when it hits the market. |

How do you enable logging in to the miner web ui when it is connected to your lan only through wifi? Strangely I can log on with the wifi IP when a LAN cable is connected, but not without a LAN cable. I tried playing arounf with firewall setting, but couldn't find a solution.  WAN has to also be set to DHCP. Yep. It won't let you resolve a non DHCP address otherwise. |

Ive only seen it affect getwork based hardware that has to talk to another device on the network, everything else seems to be fine.
