[GUIDE] BitFury Miner Support/Tuning

[cscape]

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?

[eneloop]

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?

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,

I pulled the classic 'insert the h-board the wrong way' blunder today and the h-board isn't working now. 

Does this look like the problem?



the chip at F01I has some pitting on the edges.  Is this something I can replace?

The chip F01I is a fuse, if you insert card opposite way the fuse is dead for sure, and if you are lucky that can be the only problem with that card.

so is there a part number for the fuse?  of just wire around it?

So I went and compiled latest code from git, bitfury branch; there is a bitfury_dynclock branch which I did not test because it was a little bit older than bitfury's one.

I had to install all missing dependencies but I got it running.

Here, if you trust me, the executable

MD5: 21bb61a0cc71efe973370886dac5e557

This is an ephemeral link, so I don't know how long it will last.

Hash wise, chainminer is a lot better, I had 115-130 GH reported by bfgminer after 5 minutes of hashing instead of 180-188 nonce rate from chainminer.

It has to be run as root and with -S auto otherwise it does not find H-boards.

 [2013-10-01 20:47:02] Stratum from pool 0 requested work update

So I decided to try to use it as a proxy, instead of slush's provided one which does not work with p2pool, but it does not work.

Chainminer connects to it on port 8332 but all submitted shares are counted as hardware errors by bfgminer which does not submit any share to the stratum pool. I've tested it with p2pool and HHTT, same result.

To sum it all: it is a very early beta and has a long way to go before reaching chainminer speed and fine-tuning abilities (there is no way yet, or I was not able to find it, to set single chip speed, for example).

Maybe it could be easier to just add stratum support to chainminer...

This might be the fuse you are looking for.  I'd confirm the dimensions.

edit - not sure what voltage you would need.  Its also a resettable fuse so check resistance with a multimeter.  If it has returned to a conducting state and the board still isn't working then something else has fried.

Thanks intron. 

An ohm meter shows the fuze is still closed.  I tried plugging the h-board into a different rig and it works, so my problem is in the m-board side.
