Currently experiencing connectivity issues with our hosting provider. I'm looking into this now.
It looks like no one is hashing on Bitminter. "Connection refused". |

Tried this, too. It was actually the first thing I looked up. With continuous ping I could see a time frame <1s where the MR3020 answered on 192.168.1.1. Afterwards ping stopped working again. |

This week I bought one MR3020 and flashed it with the technobit firmware (openwrt). Everything worked fine until the switch of the lan interface to dhcp. The MR3020 started, but no connection was possible. Trying to switch the MR3020 into failsafe mode failed - neither by pressing the WPS button or by change the position of the sidemounted switch. So I bought a CP2102 and followed this guide (no additional resistor was needed). Afterwards the MR3020 worked again, but this morning the usb psu was defect and I had to use one of my phone usb charges. In the end, I am starting to hate the MR3020.  Actually, if you had another router, you can check the DHCP client list or statistic to find the ip address. For the power supply, i use 5V from same PSU that powered the miner  Looked into other router and also configured dhcp server on my linux machine. The MR3020 did not want to connect to anything. Even nmap could not find it.  Alas, as the serial console worked, the problem was obvious. It was configured to use a static ip, but no ip was provided. Hence, I totally bricked it.  |

Use following command: ./autogen.sh --enable-hexminera --enable-hexminerc

So, again, no refund or real answer. Just laughing at fraud victims. DON'T BUY FROM TECHNOBIT.EU SCAM COMPANY!Exactly, do not buy, so I get my orders faster. LOL. |

The board is working stable @ 90+ GHs ( about 30+ GHs per chip) 8-10 hours already Here is the preliminary look of the miner with cooling    Nicely done. Alas, have you thought about different fan placing? Those two fans look really loud. Maybe something like an AntMiner S1 construction? Where the fan blows horizontal on the board and not from top and bottom? |

  That has very low performance.. :/ You have six miners, but cgminer only shows five. Something is wrong. My guess is, that a raspberry pi can only handle up to three hex16a2 or ~1200 WU/m I have 4 hex16a2 on one raspberry pi and similiar GH/s. |

you should connect the 24pin atx connector and put in a paperclip or a little piece of power cable in the green and black wire like in the picture , i`don`t know if your fan is going to spin i think it will i have corsair cx 750m and when i put in a paperclip in my green and black wire the fan spins without even connecting any device to the psu..  so do this: disconnect the psu from the wall socket connect 24 pin atx put paperclip in green and black wire put some electrical tape on top of the paperclip (24 pin connector) make shure every thing is connected to the HEXc power on psu happy hashing This fixed my problem after hourrrssss of trying!!!!!!!!!!! You can always buy one of those - often used with water cooling. Also look more professional.  |

Hey there everyone! I am so close but there is still something going wrong.  Anyone know why this happens? Are the boards powered 12v? Doubble check it pls I have a corsair rm750 connected to the boards. I am retrying everything again tonight i'll seewhat happens otherwise i'll set up TW. Had some similiar behavior as I attached two HEX16A2 with Sata to Molex adapters to my current PSU. As it turned out, the Sata To Molex Adapter was touching the board and could not be inserted completly. A knife and some minor tweaks to the adapters and everything is working fine. Maybe you could check, if this might be the case with your setup, too. |

Any idea when these boards are back in stock (chips included)?
Thanks!
How about ... now! |

What is the power consumption like?
This. It's the only bit of information I'm missing here. Me too. I want to buy a PSU, but do not know how much W it will need for 4x HEX16A2. |

any ideas on wether or not this hub would allow over clocking beyond 50 osc6 bits if they were plugged into he 1.2 A ports? The 1.2A ports only work, if no computer is connected! On the page you will find a footnote: 2 Enter the Fast-Charge Mode by disconnecting the DUB-H7 from your computer, or by powering off your computer. It is recommended that the total power consumption of
the connected USB devices should not exceed 2.4 A, or 12 W. I would recommend an USB3 Hub. USB3 allows up to 900mA per port. any recommendations on one for an rpi? rPi doesn't support USB3.0 unless its updated now. rPI supports USB3. Update the kernel, on raspbian with "sudo rpi-update". |

Put it on the anti static foil/bag on the motherboard box. |

Since Bitcoin 0.3.23 the client does not mine bitcoins. Please read the Miner Beginner's Guide and download one of the specialized clients. Also, do not register at deepbit, because it is growing to strong and has already more than 50% of the mining capacity. |

0.00 BTC per day. I just not mine.  |

It is a scheme. Do not participate. Only if you are in the first two or three levels, you get somethng worth out of it.

Try to install it instead of copying.
