**US** BitFury Setup Guide

[-Redacted-]

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.

That may or may not be an issue.  Log in as pi with password raspberry, and do a "sudo screen -ls" to see what processes are running.

You should have one screen process running for each proxy you have enabled, and one for the miner.  I only have one proxy running here...

pi@bitfury ~ $ sudo screen -ls
There are screens on:
        27739..bitfury  (24/09/13 23:30:00)     (Detached)
        3657..bitfury   (21/09/13 02:24:32)     (Detached)
2 Sockets in /var/run/screen/S-root.

EDIT:

Make doubly certain your new pool config is correct.   
You can't use http:// in front of the pool URL.   
You can't be using port 8332, 8333, or 8334.

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.

Have you tried clocking the chips down? Mine seem much happier at 54 or 53 with the higher voltage. I need a bit of patience with mine as well, it often does not achieve its top end for a few hours.

I filled in all three proxy's but they are to the same pool.  That's the way I had it set up when it was working.
My screen is also going off and on occasionally.

That looks correct.  Now do a cat /run/shm/.putstat.log

That will show you if the proxies are doing anything and the port they're connected on.  I only have one running so mine looks like this:

6 1461752 937198 937192 [ 0 ]http://127.0.0.1:8332/
0 1390783 839498 839498 [ 1 ]http://127.0.0.1:8333/
0 1396964 703864 703864 [ 2 ]http://127.0.0.1:8334/


If that looks OK, do a   cat /opt/bitfury/rpoxy_pools.conf and see if it looks mostly like this.  Again, I only have one enabled.

POOL1_START=1
POOL1_ADDRESS=stratum.bitcoin.cz
POOL1_PORT=3333
POOL1_USER=xxxxx.work_01
POOL1_PASS=xxxxx
POOL2_START=0
POOL2_ADDRESS=stratum.btcguild.com
POOL2_PORT=3333

POOL3_START=0

Not really.  I turned off the last two Proxys.  Here is mine:

0 754 0 0 [ 0 ]http://127.0.0.1:8332/
0 773 0 0 [ 1 ]http://127.0.0.1:8333/
0 761 0 0 [ 2 ]http://127.0.0.1:8334/

Well, if possible post your  proxy_pools.conf  (not rpoxy_pools)  - I don't think they are running.   I'd guess bad config...

As a sanity check, you can always put the original pool configuration back and try restarting the proxies.

Did the Sanity Check and it started right off!  WTF.  I guess I can't use that pool?

You got me there....   I haven't tried to run bitminter in the bitfury.   Give me a minute to try it....

Seems to work for me, but I use multiple workers, so my username is    redacted_worker3

                                                                 Rej   Acc
I got a crapload of rejects when it started up:   77   43   

Hashrate gauge on the stats page seems screwed....

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.

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

[Swimmer63]

Just noticed some earlier posts from today.  Some have it working fine.  Others do not.

I use this just fine :
mint.bitminter.com             3333           XXX.BF1       XX1
mint.bitminter.com             3333           XXX.BF2       XX2

I think your problem is trying to use port 3332. use 3333 and 2 workers

INTERESTING: I just changed from 3 workers to 2 workers only, and my hashrate has gone from 30.5-33 GHash average per 'bitminter shift' to a much more steady 34.2-35.0 GHash. It seems bitminter does NOT benefit from 3 workers>2 workers. I have yet to see how 1 worker only is handled, but this seems pretty optimal at the moment

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.

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?

EMC has 0% DGM.  

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
