I would also recommend the following if your hash rate is fluctuating wildly using automatic settings, it definitely stabilized my rate!
(I'm only running 4 boards, so I didn't change voltage settings.)

Thanks GandalfG!

Ok there is 16 factory overclocked board. I think PSU can't handle that much.
First set speed on all boards to 52
Login to Pi and do command

Code:

rm /opt/bitfury/best.cnf ; for i in {1..256} ; do echo -e "$i\taIfDSo\t52" >> /opt/bitfury/best.cnf ; done

1 - After that try run with 12 boards for test for 30 min.
2 - If no hash drop, shutdown miner and add 1 more board.
3 - Make test.
Repeat for max board count working stable.

I strongly suggest decrease voltage on all boards. Turn little pot near Pulse inductor on Hboards counterclockwise about a quarter turn or so.

You can probably get a list of clients by browsing to your access point ip address.

Hi! I download the raspberry pi image from the first post https://dl.dropboxusercontent.com/u/43738391/2013-Sep-27_BFSB_GM2.rar and write it to SD. Now how can I connect to Rpi? What is the default IP in this image?

did you try 192.168.1.249?

I think the software takes the network address and replaces the last number by 249, so if your network is 192.168.11.x your bitfury will be 192.168.11.249.

You can probably get a list of clients by browsing to your access point ip address.

It uses dhcp and gets the first free ip from your router/switch... just look it up in your router or switch.

Okay I got it working. The only problem I got now is that I can only get bank number 1-11 working. I have 12 plugged in. but only 11 looks to be working.
I’m have a problem running the rig when I have all 16 h boards plugged in. it would just power up and shut off. But when I remove 4 (left with 12) it would power on and I would be able to hash. However it would only hash with 11 boards. i've also notice that after hashing for about 20min or so, some of the h boards stop hashing. only 4 would be hashing still and the rest would stop. why is that?

Any idea on how to fix this problem.

i doubt that its the psu. but i could be wrong. my psu is 700w and 570w towards 12v. i have 2 pci-e cables on the psu.
if you think its the psu. please direct me to the right place to buy the right psu.
psu model:
coolmax

Mboard version ?

mboard is v3.0

That PSU is definitely insufficient, because it is multi-rail and has low per-rail limits. Even if the two cables are on separate rails, you can only pull ~400W from them before you exceed the PSU's specs on those.

Go get a high-quality single-rail PSU with at least 700W on the 12V rail.

Here's a good one for $90 if you don't need it to be modular: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182073
I try to find ones that get good reviews from JonnyGuru or HardOCP.

Guess I should mention it in here.

I've written a cgminer driver (it's in the current cgminer 3.8.0/3.8.1) for the BlackArrow Bitfury V1 boards.
I've no idea if that is the same as a standard Bitfury board - I never had one and the twits would never sell me one either.
... maybe I should have put in the copyright header that Punin and Buzzdave aren't allowed to use the driver Cheesy

Anyway, as I posted about it the other day:

Quote from: kano on November 10, 2013, 05:44:09 PM

For anyone who has a V1 BlackArrow Bitfury board - the latest cgminer 3.8.1 (3.8.0 also) has the RPi source for a driver now - consider it an early release since there are certain improvements I'll make to it that I've already sorted out what to do - in future versions - but it already runs with great performance.

The configure option is --enable-bab

It runs at 39.9GH/s valid shares with a bit under 10% HW errors above the 39.9GH/s on a standard board
i.e. if you were to also count bad nonces returned (which I prefer not to but I will mention in case anyone wishes to compare that number) it's returning 44GH/s of good+bad nonces.

I've run it with a single board on Raspbian to write and test it - it's based on the V1 initialisation of a single board.
I based the I/O code on the chainminer GPIO/SPI code as should be obvious for anyone who looks at my driver-bab.c and chainminer (as I also mention that at the top of driver-bab.c)

It's a bit CPU hungry so soon I'll be spending more effort on reducing that - 20% CPU with a single board - I've only tested with a single board.

It also doesn't tune the chip at all - so there is also assured performance improvement there - it runs at default settings at the moment.
That's the next effort I'll expend on the driver.

If anyone has a standard V1 BitFury board I'd also be curious to know if it works with them.

Tried it, built with --enable-bab, but it didn't find any chips.

Edit: i have 5 v.12 boards, but i suppose that the version shouldn't matter. Had to run with sudo as cgminer wanted access to /dev/mem.

I'll be happy to try more builds/do debug runs, if there will be any development regarding these boards (although it seems that the motivation might be lacking Wink

). Would love to replace the chainminer/stratumproxy combo with more sophisticated system.

I have a version 2.3 M board. I updated my Chainminer and now it only detects 2/5 cards.

there is no best.cnf file

and instead of 5x16 = 80 chips, my bitfury shows 88 chips when I know there are only 80 chips.

My question is what do I do now?

Reboot it until the problem goes away. Try reseating boards also.
