hi tom ! my interfaces are some how got delete or gone(( can't found it !!!! when i did "sudo nano /etc/network/interfaces" only a blink page came up!!! i am so fucking lost!!! can somebody i could talk over phone and help me set the rig up please?? i could send 1btc for reward !!! thank you very much. (just pm me with your number and will call later today!! have to go to work now(()

Dave,

My chip #2, #10 are only hashing at ~0.25-0.29 GH/s (with very large number of errors, 300% more than other chips)
They show "speed->0" after the last column in .stat.log

They are set as auto "AIfDSo 55" like the others.

Is there anything that can be done to improve their performance?

How are the chips numbered? How to map the IDs in .stat.log to the board?

2 AIfDSo 55 0.243 2.019 17 126 0 0 191 [0:1] 726 0 1 2 2 1 0 0 0 2 0 3 0 4 1 1 0 9 8 7 7 8 9 9 9 7 9 6 8 5 8 8 9 speed->0

10 AIfDSo 55 0.272 1.924 19 110 0 0 182 [0:9] 722 0 2 1 2 2 2 0 2 0 1 1 1 2 1 1 1 8 6 7 6 6 6 8 7 8 7 7 7 6 7 7 7 speed->0

Thanks,
af_newbie

EDIT:

After a while they go to:

2 AiFDso 55 0.014 0.550 1 35 0 0 52 [0:1] 723 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 2 2 2 2 3 3 3 3 2 2 1 2 2 2 2 2
10 AiFDso 55 0.072 0.528 5 34 0 0 50 [0:9] 715 1 1 0 0 0 1 0 1 0 1 0 0 0 0 0 0 2 2 3 2 2 1 2 1 2 1 2 2 3 3 3 3

hi everybody!! got my starter kit today, but ran in to problem during set up so power down, and now the pi have no video out (hdmi) red power light are on, can anybody help please!! never use pi before ((

thanks

You don't need hdmi. As long as you know or can figure out the IP address you can just SSH to the raspberry pi with a tool like putty should you require command line access, else just web browse to the units IP address. If its still at the default address, just put your pc on the same subnet and access the default address via SSH

Thanks Lubah!! got the video out working and able to fix Gateway IP, but now have no idea how to reconfigure pool credential via SSH? (I have a macbook pro can i just plug an ethernet cable from my laptop to the router, and use the 192.168.1.249 with a browser??)

thanks

If you have your rPi set to a good ip address for your network then you should be able to plug it into your network and then access it at whatever ip address you set it to.

ie: instead of http://www.google.com in the address bar of your browser you just use the ip address you set the rPi to.

You'll get a webpage that you fill out with your credentials.

still unable via SSH to pool credential(( is there a way i could log in to pool credential from command line access by hook up monitor/keyboard to the Pi???

If you know the IP address of your rig, just put it in the web browser. You'll see the BitFury Admin page where you can configure your pool credentials. No ssh needed for doing pool credentials.

thanks dave!! but now i am even more lost!! try to get the correct IP address by doing "sudo nano /etc/network/interfaces" now a blink page came out (((( dont know what to do !!! can somebody help Huh

Thanks

You can check ip in your router.

tom thanks, but if that gateway IP file are blink is it a problem ?? never use a Pi before so I'm fucking lost Huh

This is what I have in my interfaces file. Hope it helps. Of course change the ip ranges to match your network. My network just happens to use 92.168.169.xxx subnet

auto lo

iface lo inet loopback
iface eth0 inet static

hey jddebug thanks !!! checked my router IP address are 192.168.0.x but also have a router address 192.168.0.y which one do i use?

Bitcoin / Crypto mining Hardware.

BTW my hashrates on the pool (Eclipse MC) fluctuates a bit too much with Bitfury.

The hashrates on the pool is relatively more stable with my Avalon and BFL Jallys.

Any idea if this is a good fix?

Code:

After removing the -rt (or --real-target) flag from my stratum proxy, this hasn't happened again. This change results in a slightly higher load on the Raspberry Pi that's controlling the ASIC (because the miner now tries to send every diff1 share to the proxy), so I'm not recommending anyone to do this unless you are actually experiencing the above problem.

~~Any pointers to which file needs to be modified~~
Found the shell script

Code:

/opt/bitfury/start-stratumproxy.sh

have a board with only first 4 chips hashing. I think the chips start from bottom left corner and go vertically up (U40, U41, U42, U43) down (U44, U45, U46, U47) ,..., then down the second column and then up, etc. Any tips on how to make the board fully functional. It's okay if chip 5 will not hash.

Okay problem solved. Inferring that the problem chips be disabled as per cscape's suggestion
I cut the SPI traces of 4th and 5th chips using a knife and shorted the jumpers using thin copper wire. Here are the results. The board now uses 14chips for hashing.

http://i.imgur.com/v3HhER8.jpg

I fixed an EOL board by shorting the solder jumpers. no need to cut the traces. Funny, my EOL board with disabled chip is hashing at 25GH/s

How were you able to tell which chips were bad?

Where's the reference to how to fix the problem?

Thanks.

The number of chips that chainminer detects stops at a certain number. that is the last good chip. solder the SJ pads next to the first bad chip (these are the pads connected via traces from the chips).

BTW what was the initial hashrate of your EOL board?

It was around 15GH/s before.

looks like you 'destroyed' the connections for 2 chips in your board between chip and resistor set. Is that the effective way to disable the chip? Does it still take power when the board hashes?

After removing the SPI connections and clock, the chips were cool to the touch on the running H-board.

Ok - thanks Dave. I entered a return for it on the website, but sounds like you'll probably have the version-2 boards before it gets processed.

I've got a bad M-board from order 76. The one from order 78 was OK, so I have both starter kit cards hashing on the one m-board that works. Any idea when you might be shipping out the version 2 m-boards? If it's going to be in the near future, I can just wait for the replacement.

I expect V2 M-boards next week...

Forgive me. How do I see the chainminer information? I'm used to logging into my linux rigs and screen -x to see my screen session with cgminer running. Is there a similar interface with chainminer?

It's okay if chip 5 will not hash.

Okay problem solved. Inferring that the problem chips be disabled as per cscape's suggestion
I cut the SPI traces of 4th and 5th chips using a knife and shorted the jumpers using thin copper wire. Here are the results. The board now uses 14chips for hashing.

I fixed an EOL board by shorting the solder jumpers. no need to cut the traces. Funny, my EOL board with disabled chip is hashing at 25GH/s

How were you able to tell which chips were bad?

Where's the reference to how to fix the problem?

Thanks.

The number of chips that chainminer detects stops at a certain number. that is the last good chip. solder the SJ pads next to the first bad chip (these are the pads connected via traces from the chips).

BTW what was the initial hashrate of your EOL board?

It was around 15GH/s before.

hi everybody!! got my starter kit today, but ran in to problem during set up so power down, and now the pi have no video out (hdmi) red power light are on, can anybody help please!! never use pi before ((

thanks

You don't need hdmi. As long as you know or can figure out the IP address you can just SSH to the raspberry pi with a tool like putty should you require command line access, else just web browse to the units IP address. If its still at the default address, just put your pc on the same subnet and access the default address via SSH

Thanks Lubah!! got the video out working and able to fix Gateway IP, but now have no idea how to reconfigure pool credential via SSH? (I have a macbook pro can i just plug an ethernet cable from my laptop to the router, and use the 192.168.1.249 with a browser??)

thanks

If you have your rPi set to a good ip address for your network then you should be able to plug it into your network and then access it at whatever ip address you set it to.

ie: instead of http://www.google.com in the address bar of your browser you just use the ip address you set the rPi to.

You'll get a webpage that you fill out with your credentials.

still unable via SSH to pool credential(( is there a way i could log in to pool credential from command line access by hook up monitor/keyboard to the Pi???

have a board with only first 4 chips hashing. I think the chips start from bottom left corner and go vertically up (U40, U41, U42, U43) down (U44, U45, U46, U47) ,..., then down the second column and then up, etc. Any tips on how to make the board fully functional. It's okay if chip 5 will not hash.

I tried that, it still didn't solve the issue with my board. That's why I had to cut traces.
