can someone explain the concept of the Banks and how they apply to v2.2 H boards and v3 M boards?

Dave said that the Banks are obsolete and that the H boards are just numbered 0-9, A-F.  however, on 3 of my M boards i have one entire bank at zero; 2 Bank 1's, and 1 Bank 4.  there must be some relationship btwn the 4 adjacent cards in those Banks.

any suggestions to revive those Banks?

Even v3 M-boards have 4 banks of 4 slots each.

Try reseating cards, or rotate the 4 cards within a bank.

If you think the problem is related to VRM thermal/current overload, try disabling a chip or two on each card, or turn down the voltage with the trimpots.

i have heatsinks and multiple fans so hopefully it isn't thermal.

i know the GUI shows 4 banks but do they have a function?  Dave did say they didn't mean anything.

Not sure where Dave said that, but I have seen it mentioned by many people (dave including) that you want the fastest H card in the first slot of the bank, then order them in descending order with the slowest card in the last slot.

Can you link where he said it didn't matter, because I think it does and I dont think he'd say this. In practice, I can confirm its better to have the faster cards in the first slots of a bank otherwise it can cause the other cards to run slower or not run at all.

"Don't pay attention to the Bank 1, Bank 2, etc.  Those line up for V2 M-boards.  The numbers of the slots do line up as 1-16 map to 1 - 9, A - F.  There, you can see the output of each H-card."

Hmm, wish you could quote it in context.. anyways.. Anyone else having trouble getting bfgminer built? I've tried it how I thought it should be done, and a couple instructions of how others thought it should be done. Nothing's working.

This is so frustrating.. after over 24 hours of troubleshooting, one is now running at full speed on admin page, but half speed on the pool. The other I seem to have corrupted chainminer while troubleshooting it and it isn't hashing at all. Certainly buzzdave is experiencing these same issues since he is using the same hardware to setup the 200 Th mine. I wish he would be a little bit more proactive about supporting us... perhaps release an updated firmware that fixes a lot of the issues everyone's having. Usually when I spend $16,000 on something, I expect it to work.

I'm confused as to what the A autotune is supposed to do, does it not raise it past 53? Im getting similar numbers to Keefe but have everything just running with Autotune at the moment.

Did you adjust your Difficulty for the pool for one running at half on the pool?

Did you adjust your Difficulty for the pool for one running at half on the pool?

The only pools I've tried... Eligius and Slush don't have adjustable difficulty I don't think.

Maybe I should try one where I can..

Hope to do some troubleshooting of the second rig tonight after picking up some proper tools at Frys earlier.

Is it safe to assume that turning the pot all the way left should be most stable, and turn all the way to the right at your peril ?

 Also, thanks Frys dude for selling me a Netgear WNDR3400v3 and stupid me trusting him that it works with Dd-wrt for use as a wireless bridge...

Ghash.io is super spiffy that way, and btcguild is really good at automatically setting your diff to handle your hash rate, in my experience.

Yeah, these are pretty sensitive to that.

Wow.. I switched over to BTCGuild @ 512 difficulty & it is already showing faster than both Eligius and Slush's pool. It's showing 476, hopefulyl it winds up closer to the 524 Gh the firmware shows.

I'm going to cross my fingers that this was what was wrong all along. I'm so happy I made a backup image of the sdcard before I started troubleshooting, I can restore that image to fix the corrupted chainminer and hopefully be good to go if the pool was really the issue.

protip: backup your sd card using a digital camera/laptop with sdcard reader/sdcard reader and use win32diskmanager to copy the image file from the sdcard to your computer for a back up. You can use the same tool to write the image to the sdcard as well. The images provided in the bitfury support guide thread (in mining support subforum) were too large to fit on my sdcard for some reason.

i recommend signup for a free account at ghash.io

Well, BTC Guild is working perfectly. I don't really want to change it right this moment. I got the other rig re-imaged and both are showing over 470 Gh worth of submitted shares. That's the best I've done so far.

I do like to have accounts at different places for use in the future though. I thought ghash.io is a private pool, where can you register an account?

You make an account here https://cex.io/ , and you get an account for the Pool as well which is ghash.io

[CoinHoarder]

Thanks, I'll check it out.  

I've never signed up for cex.io cause... well, they're overpriced Ghashes. So, it's nice to know that's the secret for entrance to ghash.io

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.

   Why hell blacklist spi

pi@raspberrypi ~ $ cat /etc/modprobe.d/raspi-blacklist.conf
# blacklist spi and i2c by default (many users don't need them)

#blacklist spi-bcm2708
blacklist i2c-bcm2708


I need to enable spi and I need to update raspi-config to see enable spi thing.

To get bfgminer working on my v1 m-board I made a quick change to

driver-bfsb.c


Change line 76 from:

Code:

        for (i = 0; i < 32; i++) {
                if (slot_on[i]) {
                        int chip_n;

to:

Code:

for (i = 0; i < 1; i++) {

As it was detecting all 96 chips in each slot and getting confused.

This isn't a proper patch, and you won't get per-card stats, but it does seem to work, and I can finally use eligius again w/o queue overruns

Code:

bfgminer spends a lot of time reinitializing chips if their error rates are high; I'm not sure if this is slowing the whole thing down or not. Anyway, that's all the effort I'm putting into it for tonight

   Thank you working good now with change for V1 mboard.

Productive night of troubleshooting... Thanks to everyone for all their pointers and advice in this thread.

dammm nice hash rate...how much did it cost you?

[Eternity]

Are you still selling them ?

[shade88]

Are you still selling them ?

They are sold out atm. Wait for cheaper December batch.

If chainminer causing headache for you, bfgminer is available. 4 boards yield 140GH/s.

  that 2xfull kits that was 1.6kusd and damn everyone is looking to add more hashrate power.  Gox is hitting 400usd for btc.
