use cp  /run/shm/.stat.log  /opt/bitfury/best.cnf

you can read more about cp command http://www.computerhope.com/unix/ucp.htm

1. How i copy /run/shm/.stat.log to /opt/bitfury/best.cnf ?
2. How i get /run/shm/.stat.log ?

Why are you compiling chainminer? If all you're trying to do is change clock speeds, just edit /opt/bitfury/best.cnf and reboot. If that file doesn't exist yet, copy /run/shm/.stat.log to /opt/bitfury/best.cnf first.

I made step by step, but i cant acces, 6. How to start tuning chips manually?

What is wrong...? I get:

Just doesn't seem to be a good idea skimping on fairly inexpensive PSU's, or pulling out power cables to turn off an expensive rig - for the same reason you wouldn't expect a motherboard to last for very long if that was how you shut your computer down - by pulling power cables out of the connectors.

PSU's have bleeder circuitry to prevent big amp surges from taking place when you shut them off.  If you yank a connector out of the socket, or just pull the plug out of the wall, there are lots of electrons that suddenly find themselves needing to go home -RIGHT NOW- and they aren't too fussy about the path they take getting there.  They're perfectly willing to make themselves a new path of least resistance, and will happily travel through - and burn up - a part that wasn't designed to handle that kind of surge, if they can.

Just sayin'...

I only mention this having learned a great deal about electron return, flyback currents, and paths-of-least resistance working in an environment that sometimes required us to switch 100Kv @ 10K Amps on and off.  (Think LHC accelerator-beam superconducting magnet type power.)  People are better conductors than air-gaps, and electrons were more than happy to oblige if you did something incredibly stupid and offered them a shorter return path than the one you expected them to take through air gaps and enormous relays and pools of mercury. 

Hmmm ... I don't know why you think I would deserve something ... but anyway ...

I'm working with 2 PSU right now until stability isn't an issue anymore and then move onto one PSU.

Thx for all the constructive comments especially yours Redacted.

Peace and happy mining.

So he's going to yank power connectors off - and risk damaging - multiple, multi-thousand dollar pieces of hardware just to try and save himself $90 on a PSU?  

He deserves whatever happens to his rigs...

He wants to power multiple rigs from one PSU but be able to turn off just one of them.

Rather than trying to switch all that high amperage, why not just use the green wire on the 24 pin connector the way it's meant to be used - as an on/off switch?  You don't normally turn off your computer by yanking out the PCIe power connectors from the motherboard, or by yanking the plug out of the wall, do you?  It's bad for the attached electronics to do it that way.

Little overclocked (2k2 resistor instead 1k8)  H-Board with RPi  take 2.4-2.6A 12V
Thats means 2A 12V are minimum for one board.

Even without overclocking, a full rig pulls something like 25A from the 12V input. You'll need a much heftier switch than that.

As the 12+ of the cable comes from one output u could just add a kill switch to it, cut the cable and solder the switch. Any 220V 10A rocker switch would do the trick, dont forget to insulate the soldered terminals. Or you can make an patch cable out of these (link) and the switch, that way you dont have to hack you psu cables.

Shouldn't be a problem at all for the few seconds it will run with a single PCIe even if it keeps hashing, but you can stop the miner and power-off the RPi first (recommended in order not to damage the file system)

I've some questions ... maybee some one has a good solution ...

I'm using a multi rail atx psu ... 1200 Watt ... at which 2 miners are connected.

So if I want to do some overclocking at the moment I've to shut down both miners ...

What solution do I have to only shut down the miner Im modding ....

1) just pull out the pcie ... one by one on the miner? dangerous? also is reinserting to have it on again ... a problem when connecting one pcie after the other when psu is on?
2) is there a switch for a pcie cable? ...
3) a second psu ... yep i got one but i would be happy to only use ... one ...

thanx or your help

You're welcome.

Thank you! It was enough. Very helpful!

On your bitfury kit stratum-proxy listens on three ports, one per each configured pool on its webgui.

8332,8333,8334

It should be enough to configure your blade to point to your bitfury kit's IP address:8332 to have your blade configured to mine on your first configured pool.

Mind you, I don't have blades available to test.

Hi! Can anybody explain me how to connect to bitfury's stratum proxy (located on raspberry pi) with my erupter blades? They are plugged into the same switch port as bitfury starter kit. Is it possible to use the starter kit's stratum for blades? Thank you!

The link works for me dacman61.  I'm not sure how it works but it comes up with 15 pictures of a burnt chip.

   I got 2 Hboards same as your hboard died with 30 minutes and board got very hot melt down solder around chips.  I got 3 newer hboards but need AC cool down it or hboards will shut off every 10 minutes without AC on it and too later for other 2 died by overheat.
