using SSH:
USERNAME: pi
PASSWORD: rockminer
/etc/cgminer.conf - contains very little hardware settings outside of icarus-options:115200:1:1 - is there another file that determines fan speed/PWM control and chip frequency?

I wouldn't fret about duplicate shares unless your difficulty setting is really low and you're worried about sending 10-15% extra up the pipe. My best hashing results were on ghash.io >450, and worst on eligius <450, although, I'm not really sure why...
As far as frequencies go, you may want to try setting --rock-freq and see if it acknowledges it in the same way r-boxes do. I compiled rockminer's cgminer fork on Linux x86 and ARM, and noticed in the UI that it's using a new auto frequency setting. It appears the default is 350.

different frequency commands seem to have no effect. I added rock-freq, amu-freq, and rmu-freq options of 330 and 12hrs later still have a 940GH hashrate with 12.5% errors. I switched to a 90CFM fan on one unit, and it still wasnt enough to keep it cool. using a pair of 60cfm fans to col the outer heatsinks helped though. I really need a silent 110CFM option available in Canada |

Has anyone managed to get their RK-BOX successfully running on P2Pool for longer than an hour? Seem's they're having the same issues I had with the R-BOX's where they submit too many invalid shares too quickly to the node and CGMiner goes down and the Pi reboots. This is the same on the PC running CGMiner or BFGMiner. Is this a known issue? If it is, is there a workaround or a way to get it working? I have been unable to find any information on this whatsoever so far and I'm running out of ideas.

WHEN IS THE 10-15% REJECT RATE ON THE RK-BOXES GOING TO BE ADDRESSED???
Also, is there any way to convert the RK-box to the new design?

Have spent the last day and a half trying to get my first RK-box setup.
So far this thing is just a major disappointment. At stock it runs at 280 GHs (well below the promised 440) bumping the freq up (by oh 30% or so) I can get it to run at 370 Ghs BUT that is generating 60% hardware errors!
I have tried numerous settings so far and the best I have been able to get it to is 398 GHs (but at a setting that generates nearly 70% HW erros and thus is useless) right now have it set at 378 GHs and it is generating about 30% HW errors.
I am going to look to see if maybe they have a new pi image available on the Chinese site yet.
Going to give it another two days of trying to get it setup before I RMA it and order an S3.

With the reject rates has anyone tried going to a pool like BTCG and manually setting the difficulty? That seemed to fix the reject rate for the coincraft 1 th/s units I have had. Letting the pool manage the baseline left high reject rates for some reason. When I manually set the base the problem stopped.

No dice here. |

Changed to the latest cgminer. 1xrkbox and 2xrboxes are hashing together nicely. HW errors at 1.3% for the last 1.5hours :-)

Can you be specific which version? Are they running at different frequencies, and if so, how did you do it? |

They are all running at 270Mhz at the moment. I couldn't make them work with separate set of frequencies yet. Guess running rboxes at 270 and rkbox at 310 will be ideal. |

It seems the results are similar (total hash rate) running the RK and R-Box at 270 or just the RK-Box at 320. I've experimented with several frequencies, but at the moment 320 seems to be the about the most optimal for the RK. |

I remember earlier cgminer had a hard stop at 290Mhz for the rboxes (when rkboxes where not released). If thats the case, rkbox should run at 320 and rboxes at 270. I will check this once I reach home. |

updated the RPi SD card to 1.3.0 and am a little happier. PWM still seems useless, but cgminer seems able to accept frequencies outside of just 300/320/350.
Im running them at 300 now because i switched to smaller, barely-adequate fans (90CFM) that really need a box fan by the unit to cool the outer heatsinks if i want to get to/past 320MHz again. error rate is around 6% now too, which is an improvement

Yes, when you specify a freq greater than 290, it kicks them all back to 270. |

Has anyone self modified the RK-boxes and gotten better cooling results? I was thinking about taking it apart and setting it up like the R3, but wanted to see if anyone had done so.
If it's pointless, then I'll just keep my box fan behind it.
Off topic, what was the R2, or did we just go from rk-box to R3?
Rockminer, do you have plans to manufacture bigger miners like Edentech's 900+ GH/s miner?
