I bought one of the low-clock only cubes. It's just as described - it runs just above 31GH/s, no problem at all.

I also have another Cube from an earlier UK GB that arrived in December, when it runs in Low, it runs at the same speed as the Low-clock only Cube.

I've also had some issues with a similar setup to the OP.

Raspbian Wheezy, with BFG Miner.

It runs 20 USB block erupters and a blue fury stick for weeks without any issue.

As soon as I connect the blade in via the BFG Miner proxy, it'll last 10hrs max before the Pi locks up.

Haven't tried the Slush stratum proxy yet though on the Pi - it may help?

Cube received this morning, just after 8am - thank you very much! Running just short of 32Gh/s on Low.

It's already been said, but a couple of the cards had come loose slightly. Also, just about every heat-sink screw had to be tightened, although no screws had fallen out.

Nobody should be putting power onto the units until they have first checked them. It might take 10 mins, but it's worth it.

Please reserve me 1x Cube - payment to follow soon.

Thanks.

I'm an arse - doing it now!

Hi,

I have a new blade, and I'm having an issue getting it to work with BFGMiner.

When I add the --http-port 8332 bit to my existing command line, BFGMiner won't start, and gives an unrecognised option message.

Running on Raspbian for a while with no issues, got some BEs and Blue fury already.


When I built 3.5.1 on the Pi, I used the commands below.

./autogen.sh
./configure
make

Do I need to add anything after the configure command...? Do I need to run a apt-get install for anything beforehand?

I'm a bit confused by the read-me file - see link below





Thanks.

Seems to have settled down as follows...

I seem to be having fairly good results so far compared to some others. I thought it would maybe be a good idea to share where I'm at so far....

I have a screen-dump to post but can't quite work out how to post it...

(i) Running BFGMiner3.5.1 on a Raspberry PI (Rapsbian Wheezy).

(ii) I have 20 USB Block Erupters and 1 new USB Blue Fury split over 3x 10-port hubs.

(iii) Running at 8.9GH/s. (2.3GH/s for the new blue fury)

(iv) There are 7 USB miners per hub, plus an Edimax wireless dongle, and a nice cheap USB fan for cooling.

(v) Before arrival of Blue fury, the 20x block erupters worked fine.

(vi) After some trial and error, I have all 20 block erupters and also the blue fury running under the same instance of BFGMiner3.5.1, and it's been stable so far. We're at 8.9 GH/s which seems not too bad considering other folks descriptions.......


The command I use is..........

sudo ./bfgminer -o stratum+tcp://xxx -u xxx  -p xxx -S bitfury:/dev/ttyACM0 -S Icarus:/dev/ttyUSB0 THROUGH TO -S Icarus:/dev/ttyUSB19 --icarus-options 115200:1:1 --icarus-timing 3.0=100

Hope that makes sense - as mentioned previously by others we're specifying drivers per port. ACM0 is our blue fury. USB0 to USB19 are our 20 block explorers....

Your electricity is free - nice one...! I'd have everything on 24/7!

However you'll have graduated and worked right through to retirement, before the laptop GPU will make you any decent money.

Agreed...!

Tonnes of useful info all over the forum - just a matter of searching for it.
