Ok I understand now with the power cables! Thanks for clearing that up for me.
Next question is there a way to underclock these machines in the future. I am also curious about overclocking them of course in the present time frame.

I appreciate that, can you please PM me. I need to OC it today possibly. But I do not know the clock values...

Interested to see how they do... not exactly a lot of extra cooling comes installed out of the box. |

Bobsag and I have reported good luck overclocking to 320 and 330 (the default is 310) by simply editing the run.sh file. Seems stable, cooling air output is still only warm so cooling doesn't seem to be an issue (bear in mind that I have upgraded the fans, though focused on noise not flow). |

I wouldn't. Allegedly overclocking is not possible in the new firmwareSee the quoted post from a different thread below: Looks like anything above 310 is disabled with the newest RPI image (07-19). Does anyone have a copy of the older image they could host?

I have a question if someone is willing to help. My discarded to accepted ratio is insane. Is there something I'm doing wrong or does it just happen this way?
It's the AM - V2 but this is the only place that I find any similar details.

My 3x AM-V1 miners are pumping 910 Gh/s with 37K+ accepted and 77K+ discarded and only 47 rejected. My miners have been going strong awhile and the reported hash rate on the pool I mine with is pretty much on point. |

discard number is not relevant in garden miner. I got loads of discards but still mined at 310gh as well as making profit so i was happy with it.

Thanks for the response, gonna have to bother you again...
It's supposed to go to 610 is says, but I have never crossed the 320 mark, which makes me think only half is working. I have it on a Corsair CM1000 PSU and on the cgminer settings I have it on board nums as 8. My thought is the link cables are not working correctly. But I'm not certain.
Thanks again,
Prof

Double and triple check your ribbon cable arrangement...you could have a bad ribbon cable but chances are they are not wired properly. |

Hi you expect 610 you have 4 blades so you must have board nums at 4 |

Magical, after changing the cables it went up a bit, then once I moved it to 4 it is where it is supposed to be. Thank you both. Had previously tried four but guessing there was a bad connection somewhere. It's working finally. Thanks again.
So if I purchase another one I need to have another raspberry I'm guessing, or is it possible to daisychain another 4?

I think you can have up to 8 blades (4 miners) on a single Pi. I currently have 3x AM-V1 miners on a single Pi (6 blades) |
