**US** BitFury Setup Guide

[af_newbie]

If any of you with 100gh/s or more want an invite to giga's private pool (https://bitcointalk.org/index.php?topic=206181.0) just let me know. My Bitfury starter kit is getting 0.03% reject rate there.

honest question - why would I join a private pool instead of a large one like btcguild or bitminter or eligious?

First, it has 0% fee which none of the public pools have. It does have a very small withdrawal fee and I do mean small.

Second, it is good to decentralize the pool hierarchy to minimize possible (albeit unlikely) 51% attacks.

Third, I am sure there are probably more but the first 2 suffice.

EMC has 0% DGM.

This. And the pool is rock solid. Also, it is a large private pool. Larger than bitminter and eligius in hashrate

what is bitminter's withdrawal fees? and I see donations for perks, anyone choosing any of those?

I stand corrected.    Another point is that the out of order coms issue has been fixed for bitfury miners there.

HHTT works as well, and has a very low fee

Its worth noting that after a sd card re-build, and using 2 workers and a pencil mod of 1.178k; I am getting a fairly stable average of 34.5 ghash/s, based on 33-37 ghash fluctuations.

Great result, any aftermarket cooling on your cards?

I have tiny heatsinks on the face of each chip (except 2 of them), 5 small heatsinks on the back (centered opposite the capacitor clusters), a 120mm fan blowing directly at the back and a 60mm and 80mm blowing from opposite sides on the front face. This seems excessive, and nothing on the board gets past "warm". even the Dc converter (i assume thats what the cube is) has a tiny heatsink to help shed its warmth (it was the hottest component i think)

I was using 2 workers at difficulty 8 and getting hashrate fluctuating between 30-36, with 34 being about the average over the last 12 hours. I just changed to 1 worker at diff=16 and will see how that works. 2 workers seemed to be a bit more stable than 3 workers.

I have yet to do any tuning, will wait for new difficulty to kick in and see what the .stat.log looks like. Right now all 16 chips are auto at 55 and running 1.9-2.35 ghash each, with error rates between 2-15%  (good:2317 errors:221 spi-err:1 miso-err:6)

edit: at first 5min glance, 1 worker at diff:16 seems to only result in <26Ghash at the pool. Im switching back to 2 workers at 16

Is there a place to purchase the V2 M boards? I'd really like to be able to upgrade software.

not at the moment, except perhaps from people who bought multiple starter kits that were in the delay. Wait a few weeks and MBP should get a v2 board in your hands. (whatever 'loss' you experience now will surely be remedied by having an extra m-board (with arguable resale value around 500-800$)

very nice! Somewhere in between of blade runner and borg technology!

ChainMiner for M Board Version 2.X boards
DO not use this guide for Version 1x m-boards.
It will fry your chips.  This is only meant for Version 2 of the M-board.
I apologize for grammar as I took 2 sleeping pills and I can barely feel my fingers.

1.login as pi or root

2.  type "nano /run/shm/.stat.log"   if you wish to see the performance of all the chips on your board before upgrading chain miner.
(optional step)
3.(backup your chainminer version)  (this creates a copy of the folder)
a. sudo cp -a /opt/bitfury /usr/bitfury.backup
b. cd /opt/bitfury/
c. pwd  (make sure you are in /opt/bitfury)
d. ls -al (or type dir)
e. rm -rf chainminer  (this removes everything in the chainminer folder)
4.  make sure you are in the /opt/bitfury directory and not in /opt/bitfury/chainminer (it should be deleted anyway
5.  type "git clone https://github.com/bfsb/chainminer.git"
6.  it should now start getting the chainminer git.
7.  now type "cd chainminer"  you should now be in the chainminer directory
8.  type "make"
9.  Its going to take 5-10 minutes to create the chainminer...maybe longer.
 I got some warning but everything was fine after it all finished.
 it will go back to a  bash prompt when done.
9a.  Just wait...this is the longest part of doing this change..
10.  sudo reboot

This just stabilised my error rates ennormously. I had 2-15% errors per chip (10% average). Now its under 2% average (one chip is at 6%, thats the only exception)
35Ghash noncerate and climbing as the autotune does its thing. 37.5Ghash seems like a real possibility

UPDATE: after a little tuning to 54/55 as needed, 36.5 Ghash is my new [very stable] record.

how to make a brand new sd card with the new chainminer, do I need  both chainminer and the rasp pi images downloaded

read the quoted text above your post. get your system working with the default v2 image (only for a v2 m-board), then run the commands from the RPi terminal

FWIW my v2 bitfury is now mining on a wireless network.  The setup was painless and the adapter / instructions are here:

http://learn.adafruit.com/adafruits-raspberry-pi-lesson-3-network-setup/setting-up-wifi-with-occidentalis

No drivers needed, no speed hit, just followed those directions using the 11.95 micro wireless usb on the right.  Router setup to assign a static IP to the MAC address of the wireless usb.  Death to wires!

The latest push earned me >39 GHash/second

Help?!?!

Ok, here is where i am at. I have  Pi set up with an appropriate IP. I can access the web browser interface. I believe the DNS is working since i can ping yahoo.com. in the browser i set the instances up with:

stratum.bitcoin.cz   3333   Trongersoll.Ruby thepassword

This is a V2 MB

i hit the save and  restart. 0GH/s tried stop and start, still nothing. nothing on the pool site either. i have one H card in the slot closest to the Pi. there are 4 lites on the Pi lit with the fith coming on occasionally. I'm using the image as it came from the front of this thread.

Any ideas? obvious blunders?

How long did u wait for it to start hashing? It takes a while sometimes. Other issues that can occur are credentials incorrect. I have had to resave the proxy and then wait a minute and then stop and start miner and then reload the web interface page.

15 minutes after restart and nothing. I'm hoping that someone on Slush pool will notice if the credentials are wrong but i don't think they are. Is there anyway to see what is going on at the Pi's comand line? this one has a keyboard and monitor on it.

try: nano /run/shm/.stat.log to see whats going on with the chips. Maybe your h-board is not fully inserted

you probably have the wrong (default) ip in use. did you change to your home network (usually 192.168.1.249 / 255.255.255.0 / 192.168.1.1 for ip/dns/gateway)

edit: saw you can ping out, so your net is probably ok. try another pool like
