[ANN] Bitfury ASIC sales in EU and Europe

[-Redacted-]

I understand that they've changed the R02 resistor - in effect they've permanently built the pencil mod into the hardware already.

[darkfriend77]

Is there a thread about howto pencil mod them?

they changed R01F ... you still can pencil mod R02F ... it is now in circuit 1.8k ... pencil to 1.7k brings it to 35GH ... this is what I've heard from user reporting it who already received boards ... yesterday ...

as soon as I get my boards I will try to give more info ... :-)

Awesome.  Looking forward to it...

I'd suggest a target of 1.725 at most if your not using heatsinks. Some of my boards overheated at 1.7

[GandalfG]

Wow, just wow. Punin great job. I wait impatiently for status change from processing to ship.
Especially after  better then expected KNC startup.

[Cablez]

Was there an answer on if they would ship to the US?  I might have missed it.

Great stuff, looking forward to it.

Chainminer has been updated. You can update by SSH into your pi, then

Code:

cd /opt/bitfury/chainminer
git pull
make clean
make

Then go onto web interface and stop-start your miner. We've had good results with this version even with autotuning on.

Damn, I think I could use some help! 

I did everything mentioned above, but now the miner doesn't work anymore...

I get some warnings after I enter "make":


warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.
warning: comparison between signed and unsigned integer expressions [-Wsign-compare] handylib.cpp: In member function ‘void handylib::Time::scache() const’:
warning: variable ‘tm’ set but not used [-Wunused-but-set-variable]

What should I do?
Or can someone point me to a clean SD image with the newest chainminer?

These are warnings .. nothing to care ....

You should wait 10 min ...until the pi gets back to the command line ...
make usually takes some minutes to finish ...

Warnings are only warnings. They are for developers and you don't have to pay attention to them. I upgraded my chainminer today, it takes maybe 15 minutes to compile on RasPi and it did produce multiple warnings. Did you restart the miner afterwards? It does not start automatically. You have to start it from web interface, or with a shell command:

sudo /opt/bitfury/start-miner.sh

[Cablez]

Can you do the upgrade on V1 hardware or is that not recommended?

[shapemaker]

Time to reduce price, KnC is delivering petahashes of power starting tomorrow or so. Diff will skyrocket

[achimsmile]

Thank you darkfriend and Tupik!

Sometimes I could just beat myself  After a minute of compiling: mmmh nothing is happening... maybe I should power off/on the pi? oooh the impatience!
Mining again

np... if you are using customized best.cnf, you may want to try to get rid of it and let the improved auto-tuning to do its job. In my case, the improved auto-tuning provided additional 10% hashpower.

best team ever ! i'll stick to BFSB !

How's the power consumption?

[Micky25]

How's the power consumption?

At the moment, I don't have anything to measure it, I will come back to you.
But it can't be much, the whole setup doesn't even get lukewarm

[MXRider]

Should be 500W +-15W. This is based on my own measurements.
