Yeah the Pi runs these guys pretty well but it's entirely because of the OS scheduler that it's better than more powerful machines with OSX or MSX. Our production testers are old Dell 755 machines from approximately 2008 that are stable with 10xR909 at stock speed. Meanwhile, on a newer stronger Mac...

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

What a trip! Well i've got a Pi 4 with 8GB RAM running on an SSD, so i'll grab Ubuntu and get it going for mining and see what performance i'm missing from all of these then. Should be interesting to set up!
I did all the wait factor adjustments on the Mac and it just didn't really do much. I did test the commands to be sure they were working, it just didn't do anything meaningful. So Pi it is!

I think the practical limit for a Pi is around 15 chips, so that'll run two R909 by itself. I don't know that anyone's gotten expected speed out of three together on one Pi.

I see... Well right now i just want to optimize for 4 Compac Fs and 1 r909. I assume then that is actually about as much as i could do outside of adding a couple more Compac Fs.
Good to know!

And as for the OS... I was going to go for Ubuntu MATE for being a bit lighter. Any reason to do anything different if i want a desktop UI?

i run my rpi 4 8gb ram with 2 r909 and a total of 6 compac f sticks (so a total of 18 chips) and that without any problems and performance loss. of the said 8gb ram my rpi doesn't even consume 500mb for this configuration. so i could imagine that you could connect at least one (third) r909 pod miner to the same rpi. as os i use the raspios bullseye: https://www.raspberrypi.com/software/operating-systems/ |

Does changing things in the api set the hardware after it's connected to something else? All of a sudden i'm only getting 3 of the 6 chips on the r909 showing up after a move to a different machine. Just wondering.

Hello, newbie here and I'm also a newbie miner.
I just got a R909 and today I've been trying to connect it to Nicehash, which worked but xnsub is not supported.
The customer service told me to enable extranonce using the code "stratum+tcp://sha256.auto.nicehash.com:9200#xnsub", however, it did not work.
I wonder if there is any tweak that can make it work? Many thanks!

Did you tried with this fork of cgminer ? |

Is there some way to do a hard reset on these. Mine is now stuck only showing 3 of the 6 chips and isn't hashing above141Gh and keeps resetting.

Did you tried with this fork of cgminer ? I highly doubt it would work as it will not have the s17 chip driver... You *are* aware that there is a reason #xnsub is not a normal part of cgminer right? Because#xnsub silently bypasses the coinbase checks that would reject work. Without those checks the work can switch to going to anyone, anywhere, any time, any coin, any pool, anything without you ever knowing. Great for pools to take advantage of you. Because no regular mining needs to have that ability it is not a good idea to automatically include support for #xnsub That said, it Nicehash requires it so your rental miners can change work on-the-fly w/o having to reboot. |

I'm not sure if the Pi's even support USB 3.0; sidehack can probably elaborate better on how he reaches a theoretical max. number of 15 chips. |

It's less a theoretical max and more that that's about what users have reported. It's around 15 to 18, but depends on the speed you're trying to run.
That miner showing 3 chips is a hardware issue. Talk to the vendor.

They forgot to install the blue led fan when they sent it outa and sent it to me to swap. I did that yesterday and then later that day the 3 chips went out. My guess is i'll be responsible for the "damage". Likely just out $600 and now have a dud. I'll see what they say.
What would any damage look like visibly if i wanted to remove the heat sinks and take a look? Would it be obvious? Could changing a fan even do that?

Not sure what you mean by 'led fan' but if your miner came without fan and you installed one yourself, that can't damage the device. Integrated circuits can break with or without visible damage. But if you did nothing major (like soldering / modifying the PCB), you should be able to RMA the whole device. |

You musta bought from Merch, whose "brand" is strapping blinky lights on everything. Not sure anything with a fan swap would stop the string at 3 chips, so it's probably an actual flaw and repair/replace should be an option. Contact the seller.

Right, thanks all. just wanted to get feedback on the chances i did something to mess it up. Thanks much. I've requested the return. Now i wait to see what they say. Oh, and yes, it was Bitcoin Merch  |

and i mean that is a very strong performance that all the sticks/r909 miner here get out of themselves  |

Hi Everyone,
Wonder if anyone has any ideas. Got mine a few weeks ago was hashing no problem. Came home today zero hashing. Fan is on, with blue light. Red light on front is on but zero hashing, no blinking white light and no activity on solopool??

Did you tried to link it to an other server/computer ? Is the issue the same ? Anything suspicious in cgminer logs ? |
