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

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.

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

 In the interest of full disclosure, that number is not my Bitfury gear exclusively. Have one rig running near 520 more-or-less stable, and another rig with 3 bad h-cards (2 DOA and 1 with a malfunctioning pot that won't volt above 0.127V and hashes at <2GHs) is stable at near 400. Have an RMA pending for the 3 bad cards after doing extensive testing last night.

 Will be doing more troubleshooting and tuning this weekend when I move the rigs out of their test environments.

Solved some cards shutting off by jamming a single packing peanut between each h card.  Now my rig is officially ghetto rigged snd I fear my house will burn down, but I'm getting 350 gh/s for 10 h cards

I used two rows of electrical tape along the top of the cards to hold them in place. That helped a lot.. the 1x connectors are crap and wiggle with the slightest breeze. Packing peanuts sounds scary to me, especially with how warm some of these h boards seem to be getting.

I'm not sure about him, but I bought my miners through a group buy and only own a small percentage of them.

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

I simply emailed the administrator on ghash.io  he made me 2 accounts.  I thank him for that too.

ghash.io is good if you have group buyers who own a share of the ghash.  You can set a payout address based on their % of the hash rate.


On another topic, I wish i bought more h-cards now, however at the time buying more was unprofitable.

I had performance issues pointing mine at Slush pool, BTCguild has been working perfectly.

Dave, any chance we can get an update soon?  The price of BTC is making the natives restless.  We have bitcoin burning holes in our pockets and we want to throw them at you!
