**US** BitFury Setup Guide

[mo_mo]

hi after configuring the pools in the bitfury admin page and start mining
I got 0 hash rate showing in the bitfury admin page

Bank 1
1: 0GH/s
2: 0GH/s
3: 0GH/s
4: 0GH/s
Bank 2
5: 0GH/s
6: 0GH/s
7: 0GH/s
8: 0GH/s
Bank 3
9: 0GH/s
10: 0GH/s
11: 0GH/s
12: 0GH/s
Bank 4
13: 0GH/s
14: 0GH/s
15: 0GH/s
16: 0GH/s

but on the slush pool it shows it is mining at 818.82 Mhash/s

how do you monitor the hash rate in the raspberry PI, I'm using V2 board
thank you

I tried bitminter and I get 0 Hash, anyone have this problem.

Yes and I did not solve it yet.  I was able to use mmpool.bitparking.com which is not my first choice of pool.  Bitminter works for me otherwise but not on the bitfury.  I get 0 hash on the web interface, the log file and the pool website.  I played with the settings for about an hour. 

I did adjust my netmask from 255.0.0.0 to 255.255.255.0 but have not tried it since that adjustment.

Just as a heads up I have had hashing issues on slush pool with my bitfury machines.

I recommend using btcguild until a better miner is released.

My Bitfury boards like BitMinter as well as BTCGuild.  Are you using mint.bitminter.com 3333?

bitminter works for me, make sure to create and use 3 workers at your account, since the bitfury is load-balanced (not failover). For me through, slush's pool wont read more then 10-15% of my hashrate.

in most home networks, gateway and netmask are 192.168.1.1 (or 192.168.1.0) and 255.255.255.0 respectively. ensure your settings match your network's. The webgui can sometimes benefit from using the stop miner and start miner buttons if its not reporting a hashrate. alternatively, use a program to ssh the rpi and check the "nano /run/shm/.stat.log" output to see what is actually going on per chip

Hmm, I only have 1 worker set with Bitminter.. no issues. Proxy is set with only 1 and the other 2 disabled.
Whats the reason to fill all 3?

Chainminer has no failover logic, so you can spread your hashing to two or three pools to achieve it.

I'd use no more than two, though, since every proxy instance uses around 20% of your rPi limited CPU.

thanks guys! will a different pool affect the hash rate-mining in slush vs bitminter.
I am mining in slush right now

Workers
Average hashrate showing in last 10 rounds: 8476 Mhash/s suppose to 25gh  on slush but the webgui showing Noncerate: 26.972GH/

NOTE: I was one of the late august orders and received a 4 channel 2.3 M-board. Comments in this post only apply to those with this board or later revisions.

I pulled the latest commits from the bfsb/chainminer last night and have improvement in the stability of my starter kit over the last 12 hours. Error rates have dropped from ~7% to ~2%. More importantly my previous MISO errors have nearly disappeared. The comments on the pull suggest that by increasing the spi reset rate stability should increase. The H-Card is stable at around 36GH/s. If you are going to pull the latest commits make sure to back up your current software AND make sure you have the proper hardware to do so.

I'd like to hear about other experiences with the new spi resets.

I don't know how many times I have to say this...but mining on slush pool with a bitfury takes several hours to adjust.  even then I was still 10GH/s below target with 5 boards.   Its best to go btcguild or bitminter.

Out of my 5 starter kits;   4 of them have errors below 2%.  I have not upgraded the image.  I have version 2.3 starter board as well.   I do however have 1 starter kit with 10-15% errors.   I think I just got a bad h-card on the 5th kit.  I will look at upgrading the miner on the bad kit.

^how did you do this? the chainminer 2.2 release or something different, and how was it implemented? Ive still got ssh errors (mining just fine) and plan to reformat the SD soon, and would LOVE to get my error rate down to 2% - that sounds like a dream compared to the current 6-12%!

[Morblias]

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

I had to remove the chainminer directory on the MBP supplied sd card as git was not setup on the directory. I then cloned chainminer from https://github.com/bfsb/chainminer and issued a make.

I only have an hour of logs to show here but the standard deviation on my mean chip noncerate has dropped significantly with additional spi resets. The card is consistently pushing above 35 GH/s with a pair of DC fans and a bit of graphite.

Very interesting  I have the 2.2 or 2.3 M-boards as well.   So you were at 7% error rate on one card, but now at 2%...pretty good.  What was your previous hash rate?  And what is your resistor reading at then, and what about now?

Sorry for the questions but I am very curious as to what will happen to my bad kit I got.

[mo_mo]

I have the V2 motherboard, do I need to update the chainminer to increase the hashrate?

[gmannn]

Thank you, I have a disappointing board with a 2 day hashrate average of only ~17 gh/s and a lot of MISO errors.  I'll update to the latest chainminer and see if it helps.  If not, I will return/RMA the board, rather than void my warranty by overclocking it.

The in circuit resistance is ~1.18K at room temperature. I've not measured the resistance once the system is up to operating temperature. I've moving air across the board somewhat aggressively to keep temperatures constant and the regulator happy. My digikey order came in today and I'll try to work up some stats on swapping resistors out this weekend. I'm not interested in using the pencil mod as a long term solution.

I'd take a "if its not broken dont..." stance on software changes unless you are having similar bus issues. I was interested in the spi changes (increased speed and reset rate) and have observed a positive increase in stability/noncerate by upgrading. I'll try to do a sensitivity sweep of the reset rate to find what works best for my setup on the v2 boards.

My miner has worked great since I got it going 2 weeks ago.  No restarts or anything.  But today I changed the pool configuration to another pool.  Now I can't get it to run again.  I have been restarting it both with the buttons in the browser and physically and it will not go.  Any suggestions?  Below is a photo of the start up page.  I'm a little concerned about the line that says "miner: no process found.

any sign of chips stopping at random? When I had 1.16K i could rarely get more then 15 chips working, and sometimes it would drop to 14 at times. I now have about 1.178k and 16 chips work well for the first 5-15 minutes, then it seems to drop to 15 chips again. Ive only once in the last 24hrs seen it drop to 14 chips. Im not sure if this is the chips themselves, or if the pencil mod is pushing the limits of the DC 30A converter and forcing a chip to turn off as some result of that.
