[tom99]

but putting in one night of work and calling it Bad is sortof shortsighted...

 To be absolutely clear, I'm not calling anything bad. Just a bit surprised that we seem to collectively be having some trouble getting these v3 rigs humming along, stably.

 Eagerly awaiting updates and info on how to get our babies nice and happy.

  try to run only test on bad hboad alone if hboard isnt working that meant bad.

  try to run only test on bad hboad alone if hboard isnt working that meant bad.

Going to get the second rig up tonight and start testing. Need to hit Frys to pick up another beefy power supply and some micro-sized screwdrivers.

 Was playing musical h-cards last night, moving faster cards to the front and slower cards to the back, and got one rig running along near 440gh overnight with one card going to 0gh.

 Will probably ask Dave to order an additional MBoard.

 More troubleshooting tonight... Thanks for all the tips !

[Keefe]

so my miner stopped overnight inexplicably (charts indicate it unning stable between 76-79GH (2 cards) for 36hrs) and I rebooted it and charts indicate that caused it to work for about a minute or 2 then stop again.

using SSH command /opt/bitfury/start-miner.sh, i get:

cp: cannot create regular file `/run/shm/stat.json': Permission denied
cp: cannot create regular file `/run/shm/.chip.cnf': Permission denied

Is this an SD issue or something else?

No, use sudo:

Code:

sudo /opt/bitfury/start-miner.sh

Hrm. This is not exactly how I envisioned this going. This is very frustrating.. my Avalons and KNCminers I was able to setup and get hashing within minutes. Add the assembly time of a full rig, plus the fact they're both not working....

I got two full rigs today. One is running at 225 Gh and the other is running at 0 Gh.

Code:

Rig 1:
Bank 1
1: 33.415GH/s
2: 33.443GH/s
3: 20.702GH/s
4: 21.79GH/s
Bank 2
5: 4.223GH/s
6: 0GH/s
7: 0GH/s
8: 0GH/s
Bank 3
9: 15.677GH/s
10: 10.107GH/s
11: 11.167GH/s
12: 13.758GH/s
Bank 4
13: 9.621GH/s
14: 9.893GH/s
15: 10.165GH/s
16: 20.916GH/s

Rig 2:
Bank 1

16: 0GH/s

I'm certain everything is hooked up correctly. I have checked several times. I tried replacing the PSU and that didn't do anything. I am using a 1200w to run both full rigs. I'm sorry if this is covered... (I'm going to go back and read through this thread now.) Any quick suggestions though? This thread is so long..

I'm not sure if this matters, but it seems the two rigs might have different firmware versions. One says this on the main admin screen the other does not: "Attention! Please set pool difficulty on your pool to 32-512 depending on your hashrate. Low difficulty setting will result in work queue overload, and drop your hashrate substantially. If running a full unit, please make sure all cards are installed in slots written on the back side of the card. Due to SPI bugs, the miner may need to be stopped and restarted using the buttons above."

How I fixed my problems (two rigs stable 473 Gh and 517 Gh- with 1 dead h board on the slower one):

(I don't take credit for these fixes, some of them I found out on my own and some of them I read from other user's experiences.)

I needed to find a way to keep the cards stable, they come with crappy 1x PCI connectors and are really wobbly, especially when being blasted by fans (which is necc. to keep them cool and stable). The movement in the cards was causing the rig to slow down slowly over time until the affected cards eventually ended up at 0 Gh. To fix this I used two rows of electrical tape along the top of the cards to hold them in place better.

Cooling may or may not have been an issue. I added an extra box fan in front (two box fans now) and also two computer fans blowing air down on top of them for added air flow.

I was under the impression that two full rigs would run on one 1200 watt power supply. It turns out that seemed to be overloading the PSU (a nice gold rated ASUS). I ended up using a separate PSU for each rig and that got them both mining. I think this is the main reason why the one was getting 0 Gh and wouldn't mine. As soon as I put it on its own PSU it started working fine.

I put slower H cards in the last slot of each bank to keep them from interfering with other H cards. If you have one bank that is not working but all the rest are, this is likely the issue. If the card in the first slot of each bank is not seated properly, the rest of the bank will not work.

I hope this helps someone and saves them the 16 hours of their life that I just wasted. Now... I wish I would of realized all this before spending all night messing with firmwares... flashing sdcards... installing a different OS... trying BFGminer... trying cgminer... etc. :rolleyes:

are you laying the M boards down directly onto a wire frame rack?  aren't you worried about an electrical short?

[CoinHoarder]

Although the shelves are metal, they are coated in a plastic/epoxy material. I have ran Mobos for GPU rigs directly on the shelves for over a year now with no problems, so I'm not that worried about it.

I really like these shelves for mining equipment.. I got them at target. The wire racks allow for optimal air flow.

I got my unit running with bfgminer, the only thing I could get chainminer to do was output

"M-Board version 2 detected
INIT: 256 chips detected"

Now I'm having issues with bfgminer outputting this, and the hashrate dropping.

so, in your opinion, is BFGminer definitely a better choice than Chainminer?

hmmm, mine are awfully similar. 

i laid plastic sheet down.  but it causes the M board to torque a bit due to the yellow video port lifting up the raspi end.  may have to try w/o the plastic.

[salfter]

so, in your opinion, is BFGminer definitely a better choice than Chainminer?

Chainminer kept conking out on me.  Sometimes it'd take a few tries to get it running stably, and even once it appeared to be stable, sometimes it'd die for no good reason.  Hashrate kept fluctuating.  It (or the stratum proxy) also didn't like BTCGuild.  bfgminer has been far less troublesome, so I'd have to say that it is the better choice.  That it'll also handle my BFL miners plugged into the RPi over USB is a bonus (was able to get rid of the power-hungry P4 that was running all my mining hardware).

I've not applied any hardware tweaks yet.  I've not tried backing off the voltage from the regulator, and I'm waiting for heatsinks to arrive (ordered this 100-pack last week).

of course you're right.  i've been experiencing the same problems with chainminer. 

not looking forward to the effort of switching over.

Thats one of the first things I tried, went all the way down to 50 and its still doing it.

I want to think its a thermal issue, but it was colder in that room this morning than when I went to bed, and it failed some time overnight.

Just when I think I have everything solved... I am suffering from the same issues. Noncerate in the admin panel is good... 507 Gh and 468 Gh (chainminer.) On Eligius they combine to only 594 Gh worth of submitted shares. Something is wrong here.

I've tried it with and without this cronjob mod (both on 5 and 10 minute intervals): https://bitcointalk.org/index.php?topic=250249.msg3171841#msg3171841

That doesn't seem to make a difference although 5 minutes seems really bad as reported hash rate slows down more so than normal... this is too quick. Now I am going the other way and am trying it on 15 minute intervals.... I will report back. I'm going to keep bumping this number up by 5 minutes to see if it makes any difference.

If this doesn't work I suppose my only option is to use bfgminer?

   maybe I will do it again with 52 if thing will run ok.

  still not work and got 100% HW errorrs.  I got see too many BSB like bsb0 to bsb24 but I got only 6 Hboards that fun part.

I started having issues with eligius and chainminer a few days ago. It was working fine before then. But my 6-hboard on v1 mboard setup gets >200gh/s on hhtt and dustcoin, but on eligius (with no other changes) it starts around 120 and slows down from there. I've tried passing and not passing -rt to stratumproxy.

I may try running bfgminer rather than stratumproxy as a getwork proxy; I'll report back if that works well.

Finally got it to works with bfgminer after scratching my head when chainminer can't get passed chip count

35 GH/s with only 12" fan.

  how did you get bfgminer worked with your miner?  I was gave up bfgminer and I couldn't get it work with V1 mboard.

[shade88]

how did you get bfgminer worked with your miner?  I was gave up bfgminer and I couldn't get it work with V1 mboard.

I install Raspbian and then follow the instruction here: https://bitcointalk.org/index.php?topic=251966.msg3530533#msg3530533

Then enable the the SPI with raspi-config before running bfgminer.

   Do you really need to do SPI enable with raspi-config?  I will try one more time with raspi-config to enable spi.

Thank you
