[GUIDE] BitFury Miner Support/Tuning

[klondike_bar]

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

Code:

pi@bitfury ~ $ sudo cp -a /var/www /usr/www.backup

2. symbolic link for the .stat.log

Code:

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?

Where can I measure it? (Multimeter available)

Put your probes over the terminals of C16.

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

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.

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?

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:

Code:

--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.

Try --enable-bitfury --enable-bfsb --disable-bigpic --disable-littlefury

EDIT:

Or better still:

CFLAGS="-O2 -Wall -march=armv6 -mfloat-abi=hard -mfpu=vfp" ./configure --enable-bitfury -disable-avalon --disable-opencl --disable-bitforce --enable-icarus --disable-modminer --disable-x6500 --disable-ztex --disable-littlefury --disable-bigpic --enable-bfsb

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,
