[GUIDE] BitFury Miner Support/Tuning

[Techknowledgy]

Got my 100GH kit last week and everything was working great. Then comes yesterday and all of a sudden it doesn't recognize any of the hashing cards. I restart it a few times and then it shows ghost cards in slots I don't even have, going from fully populated but not hashing to random numbers of ghost cards and still not hashing. I reflashed the SD card and it didn't fix it. I went to sleep overnight and then reflashed again and it didn't show anything. I rebooted something like 4-5 times and now all of a sudden it shows the correct cards and they are hashing. Anybody know what's up with that or experience that? I've gone through about as many Bitfury threads as I can find but haven't seen something like this. I was sweating it but now it seems to be hashing at least.

EDIT: I did switch a hashing board around because I was trying everything I could to figure out what the deal was and make sure they were all seated properly. Could that have been it?

no:

Code:

pi@192-168-7-249 /opt $ chmod 0755 /opt/bitfury/startfury.sh
chmod: changing permissions of `/opt/bitfury/startfury.sh': Operation not permitted
pi@192-168-7-249 /opt $ 

The operation requires root permissions, so you need to put sudo in front if it:

Code:

sudo chmod 0755 /opt/bitfury/startfury.sh

Yes and most likely the cause. When a board is not properly inserted, it's bad connection may result in that the chips will be detected as present on several boards at the same and different boards each time.

Thanks, I was wondering if that was the case and I reseated each individual board, but it wasn't until I switched one around that it started working again. Sounds like that was my issue in some way, though. Thanks again.

no:

Code:

pi@192-168-7-249 /opt $ chmod 0755 /opt/bitfury/startfury.sh
chmod: changing permissions of `/opt/bitfury/startfury.sh': Operation not permitted
pi@192-168-7-249 /opt $ 

The operation requires root permissions, so you need to put sudo in front if it:

Code:

sudo chmod 0755 /opt/bitfury/startfury.sh

thanks. that did it.

why 0755? 

[KNK]

why 0755? 

The syntax is 'chmod <permissions> <file>'
where for permissions you have:
4 read (r)
2 write (w)
1 execute (x)
and permissions are for 'owner/group/others' ...

755 means:
owner can read, write and execute, while the group and others can only read and execute ... the key part here is the execute permission, which can be set also with:

Code:

chmod +x <file>

meaning 'grant execute to all on <file>'

[eestimees]

no:

Code:

pi@192-168-7-249 /opt $ chmod 0755 /opt/bitfury/startfury.sh
chmod: changing permissions of `/opt/bitfury/startfury.sh': Operation not permitted
pi@192-168-7-249 /opt $ 

use: sudo ... ?

duh, i get it.  was getting confused by thinking of pid's.

I don't think changing +x to 0755 was the solution. It looked like you had some weird characters in the original command. I think the solution was just retyping the command by hand instead of copying it from somewhere.

Does anyone have advice on connecting to Bitminter via stratum proxy with a Bitfury rig?

I'm trying to connect using stratum+tcp://mint.bitminter.com (on the admin page), and the noncerate is just flashing 0GH/s. I can't figure it out.

Hey guys, I just added a few more V1.2 H-cards to my rig.
Are those still pencil modable?
If so, what voltage should I PM it to?


Thanks

Sorry for the confusion, but do I put 'mint.bitminter.com' or 'stratum+tcp://mint.bitminter.com' on the Bitfury admin page?

Right now I'm using stratum+tcp://mint.bitminter.com along with port 3333. The username and worker details appear to be correct as well. All other pools work fine (BTC Guild, Slush's Pool, etc.), but for some reason I can't connect to Bitminter.

Yup, that was it. Thanks for your help.

Ok guys, I need some assistance

I had an August kit with 2 boards (~47Gh/s)
so the M-Board is V1.0
on Friday I got 10 more boards and placed them 1st in-line then added my 2 pre-existing boards with last board being EOL one.
All this was powered by a 1Kw PS that died on me Sunday evening.
So I had it running about 48 hours.
All the new boards are stock = not overclocked.

Now I placed a spare 430W PS on the BF rig and it runs, however I can only see 96 chips running = 1st 6 cards.

Any ideas why it doesn't see the rest?

Thanks

First check if the boards are still OK by running 6 boards at a time. Do this for the other 6 boards too.
Then add 1 board at a time till you get issues.
Looks like a PSU problem. 430W is probably not enough for 12 boards.
Also try to spread your boards. Skip positions on the M-board.
Its ok to run XXXO-XXOX-XOXO-XXXX for example, X being a board.
(Some will say the boards need to be adjacent, but I have an M-board running with skipped positions without problems).

Ok, here is an update.
I tried a 480W PS no change, I opened a new 1KW PS and no change.
I shutdown the miner and yanked the card #7 and moved the rest up the chain.
Miner is UP with 168 chips showing which is what it's supposed to be in my case with this 1 card out of it.

Upon inspecting the card
https://www.dropbox.com/s/sg34hw5u2v4y8rj/2014-01-27%2007.12.17.jpg
Look at the pins above C441 and C44E
The pins are shorted (or whatever the terms for that is)
Upon further inspecting the card at last 4 chips have solder across 2 pads like that.
