Welp, ... and then magic smoke. ...
Any ideas for a cause and suggestions for a fix?
I don't think you'll ever be able to get the magic smoke back where it was. |

I need step by step help and would be very grateful if anyone can help me with this.
Link to instructions and correct software are in the 2nd post of this thread. |

am i wrong ??
Are you trying to use the .conf config file AND the command line? If so pick one and go with it. I prefer to use the command line and have never used the .conf. |

Hey everyone - so I see lots of chatter about thermal pads here. I routinely re-paste all of my asic miners every 3 months or so because they run 24/7 and my cat's dander is like a gnarly dust invasion for my miners because of all of the fans in my apartment blowing it directly at them lol. Has anyone removed the top heatsinks from the R909 and can they confirm wether it has pads or paste on the chips?
Not sure if this answers your question or not, but it seems similar: https://bitcointalk.org/index.php?topic=5423227.msg61628663#msg61628663 |

I had the R606 but it broke within 4 months at recommended max settings.
My two R606's are still hashing away. |
|

New question: Number of chip in miner vs total hash power.
In R909 there are 6 BM1397 chips, so does each chip individually participate in calculating the best share at the same time or the total hash power is used everytime to do the calculation.
Each Core in each chip is calculating shares. The total hash rate increases the chances of finding a share that meets or exceeds current difficulty. |

How did you calculate diff of 500 equate to 9.94 shares per minute?
WU:4970/Suggest-diff:500=9.94 shares per minute. |
|

What i observed is if I set difficulty too high then no of accepted shares per minute is less compared to the low difficulty setting. So I guess higher the accepted shares per minute mean more chances of calculating/generating best share.
Setting your share difficulty has no bearing on your chances of finding a block or generating a better best share. It's simply a filter used to keep from swamping a pool with diff 1 shares. Using a higher share difficulty only filters out low diff shares to decrease the amount of pool resources needed to evaluate your shares and decreases the network bandwidth required to submit shares. In your example of suggest-diff of 500, shares below a diff of 500 are not submitted and shares 500 and above are submitted. Your share submission of 9.94 shares per minute just means your hashrate estimate by the pool will have more variance than the pools adjusting to 18 shares per minute. If you remove the suggest-diff then ck solo will adjust for 18 share per minute which would be a difficulty of around 276. |

Pardon my ignorance, I have attached the screen shots of cgminer for both of these units Compac-f https://imgur.com/Da9dfncI believe the WU tells the diff1 and these are very high compared to 18. Are you expecting the suggest-diff command to have an effect on the Worker Utility? In your screen shot it looks like your suggest-diff of 500 is being honored. So that equates to 9.94 shares per minute being submitted to the pool. |

So then I think its okay to set suggest-diff of 500 for compac-f and 5000 for r909, as pool will takes care of it and adjust it it accordingly. BTW i am using ckpool
It will start at your suggest diff and then adjust to 18 shares per minute. It doesn't really matter what you set it to, pools will adjust it automatically. Pools also now have a minimum diff so that ASIC's won't flood them with diff1 shares. |

I have a compac-f getting 348.5 Gh/s and R909 getting 2.457 Th/s
What suggest-diff i should use for these individually.
I saw some calulation suggesting difficulty of 1 per 1 Gh/s / 1.8 and another one suggested Gh/s * (71 * .05)^2
Most pools adjust diff to 18 shares per minute regardless of what your suggest diff is. It is just a suggestion after all. |

Hello, I received a compac f from gekkoscience but it does not work, even after installing the correct drivers and the correct cgminer, it is marked as inactive, in the device manager it is displayed as FT232EX
Are you using Windoze? If so use Zadig to install the WinUSB driver. |

I bought my compac f and hubs from amazon.com.
Who was the seller on Amazon? Edit: the only one I see on Amazon if from someone called "Eyeboot" |

Got my R909 unit yesterday.
Great. It really was "just in time for Christmas"! Merry Christmas all. Sam |

I also used (and liked) kano.is in the past. But hell: Last block was found 417 days ago.
Well you didn't want to worry about reaching payout levels. Also when the blocks do pickup his payout is pretty small too. Solo-mining with USB-sticks seems to be a bit pointless, doesn't it?
Not sure about the USB stick's but the Pods have found blocks on solo pools. Can't bank on it but it does happen. At least use a solo pool as the last failover in your list. |

I prefer Kano.is for what your asking about.
I mined there during 2019/20 with one and then two Gekko R606 pods and got a payout every block the pool found.
This pool has very good statistics and you can create worker for each individual miner if you like.
Many do solo mining for small mining hardware. And some have found blocks for themselves. Both Kano.is and solo.ckpool.org are popular solo mining pools.

I would like to know how many compacF or S17 processors have 1 R909
My guess would be 6 |
