I have been using bfgminer  since i received my bitfury instead of chainminer and find its a lot more stable and seems to work fine with all the pools i have tried as it does  stratum itself there is no need for the proxies.

 

Anyone here solo mining with slush's stratum locally?

It uses vardiff. Now the 8889 port monitor shows zero hashing while chainminer  has been showing a stable 550 all night

This seems reasonable to me as I am a long term cgminer user.

Any tips on how to set it up?

I think I have things running at a stable 70 GH/s for two boards now.  It took a bit of stopping and restarting, and I ended up switching from BTC Guild to EclipseMC, but both the web interface and the pool say I've been mining at a bit over 70 GH/s for several hours now.

Last night, I pulled out the D945GNT and the GPUs and added a power adapter cable and a USB hub. The "adapter cable" is a 24-pin ATX extension modified as follows:

1. Tie PS_ON to GND so the power supply stays on as long as it's plugged in (mine has a hard switch on it that can be used to shut it off).
2. Bring out the two +12V pins (and GND) to a pair of 2.5mm barrel plugs for my Jalapeños.

I might add a smaller barrel connector on one of the +5V lines to power the USB hub; that'd allow me to get rid of the wall wart that was included with the hub.

This is what I currently have running:

• v3 M-board with two v2.2 H-boards and a Raspberry Pi model B (version numbers are IIRC)
• Seasonic SSR-550RM power supply (was originally purchased for GPU mining)
• Cooler Master JetFlo 120 fan (maxes out at 95 cfm @ 2000 rpm, but I have it connected through an (included) adapter that knocks the speed back to 1600 rpm as full speed may have been cooling it too much)
• a powered USB hub
• Coldtears 2.8" USB LCD
• two BFL Jalapeños
• D-Link DAP-1522 wireless bridge

The Kill-a-Watt says all this is pulling about 140W at 80 GH/s.  The motherboard-and-GPUs combo was pulling another 300W or so for about 450 kH/s of scrypt mining.  Even with Novacoin mining being worth 10x the equivalent Bitcoin mining, 300W for ~4.5 GH/s equivalent is a bit much...the Jalapeños do that with a tenth of the power.  I could probably knock a few watts off that by replacing the wireless bridge with either a USB WiFi dongle or a proper wired network connection, and by running the hub off of the power supply.  I'd like to put the Bitfury rig in one of the Spotswood cases...waiting for the $ to arrive from CampBX.

I have a bunch of RAM heatsinks on the way...will probably be a week or two before they arrive.  When they do, what's the best way to install them?  Some pictures show them applied to the component side, but most seem to have them on the other side.  I know there are a bunch of thermal vias under each chip, which would seem to indicate that placing the heatsinks on the back of the board would possibly be more effective at getting heat away from the chips.  Are the thermal vias tented or exposed, though?  I've not tried looking at them through a magnifying glass yet, and my near vision apparently isn't what it once was (now get off my lawn!).  If exposed, heatsinks on the back would definitely be the way to go, right?  If tented, it's not so obvious which would be better.

Reboot again or restart chainminer.

can someone link me to directions on how to make a backup image of the SD card onto a new one?  these look to be of poor quality and i think i have a corrupted one.

okay so i took my full kit to its final home and now its acting wierd:

I can access it through putty and also through the ip address to get to the bitfury web interface.

I CANNOT see it on my router at all.

It is not hashing at all 

I figured it was an ip conflict but I can manually ip to the bitfury using my browser, although on the router interface, I do not see the device at all.  While in testing mode at work I was able to see it appear as rasberrypi.  Any ideas guys?  Using a generic ATT 2wire wireless router.

Got my October kit yesterday and I'm happy to find out that it fits the Spotswood v2 case perfectly. The auto-IP configuration script worked flawlessly too.



With just fans and no heatsinks it only hashed  at 400-450 GH/s due to the H-cards frequently shutting down. With a single goxed-style copper heatsink behind the regulator the nonce rate went up to 525 GH/s. There is still plenty of shutting down of the H-cards going on, and I would probably need to add more heatsinks when I find the time.

IMHO these Oct H-cards come a little to hot from the factory for the average mining enthusiast. Fortunately you have the option of turning the voltage down.

The picture below shows it sitting on top of an August kit.

Check that it has the right gateway address. Is your router 192.168.0.1 or 192.168.1.1 or something else? My router is 192.168.0.1 and my rPi is correctly using it as its default gateway:
