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.

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://bitcointalksearch.org/topic/m.3530533

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 Smiley

Code:
bfgminer version 3.6.0 - Started: [2013-11-13 03:35:50] - [  0 days 00:07:13]

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 Smiley


   Thank you working good now with change for V1 mboard.

Thanks, I'll check it out.  Smiley

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  Cheesy

Well, BTC Guild is working perfectly. I don't really want to change it right this moment.

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

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.

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..

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.

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.

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...

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.. 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.
