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.

^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%!

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.

If any of you with 100gh/s or more want an invite to giga's private pool (https://bitcointalksearch.org/topic/closed-semi-private-mining-pool-206181) just let me know. My Bitfury starter kit is getting 0.03% reject rate there.

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/

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.

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.

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

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

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.

EMC is ok too. My bitfuries run at or above nonce rates.

Problem is that if there is a hiccup at the pool like I've had today, bitfuries will not failover.

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.

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

thanks so much finally able to log in to bitfury admin page,
thanks for the help I took out the ctrl-X from the file and I was able to log in
probably when I was editing the file I accidentally put the ctrl-X in there
many thanks

You are not getting an IP because there is a mistake in your interfaces file.

I hope the ctrl-X shown there isn't an actual line in the file. If it is, delete that line, save the file, and then reboot.
