The new web part looks like this ...  is there an easy way to build/'gitpull' this, or does it involve imaging the SD or otherwise turning off the miner? im hashing quite happily at the moment, and SSH is okay as long as i maintain >38 GH/s |

This is just the webpart .. it is independant to the chainminer version ... infact you can just copy the new index.php ... over the old one ... and make a symbolic link in www ... to the .stat.log file that's it 1. backup ... ur old webpart ... just incase pi@bitfury ~ $ sudo cp -a /var/www /usr/www.backup 2. symbolic link for the .stat.log pi@bitfury ~ $ ln -s /run/shm/.stat.log /var/www/.stat.log 3. download ... /www/ part from link and copy index.php over to /www/ refresh browser ... that's it... |

i just moved to another pool that chose a difficulty for me (not sure what) that forced my hashrate (both at pool and via webgui) down from 38.5->27 GH/s. I changed it to 16 manually and im all good again.
what difficulty best suits a 35-40GH/s miner? 8,16, or 32?
edit: bumped to 32 difficulty, and it seems to be a little better for my miner. went from about 38.5GH to 39.5GH

I have changed R01F to 2,26k ohm and gained about 4-5 GH/s only. Now I'm at about 51-52, before something around 47 GH/s. best.cnf is the same as before (between 54 and 56 depending on error rate). I think something went wrong, but what?

Careful when measuring the core voltage. Don't make a short, or you'll get spitzensparken. There's a lot of amps available, very eager to take a shortcut.

i usually check voltage across the caps, seems pretty reliable, esp if you want to average the reading of a few caps (usually all the same of course) |

I found a very interesting observation on one of my starter kits. One of my five h-cards shows it has a dead chip in slot a-1. If I move it to slot b-1 or c-3 that h card now shows all chips working for that problematic h-card.

I've seen something along those lines - slot A (3rd slot on 3rd bank) on my v2 m-board generates lots of miso errors regardless of the card I put in it. I can tune the card and get some of the miso-errors to go away by shutting down chips, but the errors don't happen on the same card if I move it to a different slot or a different m-board /cet |

Is there any type of failover script for chainminer? Not all of us here can run solo like the 200TH mine. I find chainminer a bit too basic, there must be more.

Tired of substandard power distribution in your ASIC setup??? Chris' Custom Cablez will get you sorted out right! No job too hard so PM me for a quote

Hi guys, I need your knowledge: Will this work or rather fry my mining gear? I plan 2 x full kits per case (old intel Server case).  The fans are Delta FFB0812EHE DC12V 1.35A. Should I give them their own, separate power supply, or can I run through the m-boards? http://www.sidewindercomputers.com/del80ffb08123.html |

Depends on your Overclocking wishes ... those cases probably offer not enough to cool the boards ... when your going for the 30+ GH per board ... im getting already 50° on the boards with this setup ... 3 fans front 3 fans back ... and heatsink  |

I'd like to know what driver exactly should be used with this branch. Looks like the bitfury & bfsb compile options would be the way to go, but ./configure --help states the following: --disable-bfsb Compile support for BFSB (default disabled)
Note the 'default disabled'. I tried --enable-bfsb, but there was still no mention of BFSB support in the configure results. I'm just being extra careful, wouldn't want to fry my boards by running a wrong driver. On that note, is there any harm in having the littlefury/metabank drivers compiled in, too? |

What voltage do you get? I have exactly 0.80 V on both. |

Hello i am new here ... But i am watching this thread from the start ...  does anybody have schematic file for the V2 M-board i just need the rpi connector connections. i am downloading BFSB_GM2.IMG is that image with v2 chainminer ? here are some pics of my miner  Hmm how to attach pics ?  Cheers, |
