Prefer US sellers due to shipping costs. Can arrange pickup if you are close. Types of things I am interested in: Water-cooled miners with a non-functioning water cooling system. Miners that don't power on / do nothing. Miners that come on, but misbehave in some way(s). Miners that have dead chips or hash at a lower than expected rate. Scrypt or sha-256 are OK. Prefer complete miners, but let me know what you have. Would be willing to pay shipping, escrow, and small amount for trouble of packaging. Would pay more for miners that only have small problems. Thanks! Edit00: Have had some offer me gridseed pods. I have lots of those but would be intersted in a G-blade. Working or not.  Edit01: Due to difficulty increases, only looking for broken newer stuff. Thanks to everyone for your offers! |

Hi m.gimmer84, I'm not sure about your settings there, as I don't know if there is a frequency 0 setting, but you don't need to go that low. It will also depend on what model you have. But for the most common, 700Gh, I use the following BFGMiner parameters to run around 500Gh @ somewhere about 330watts. This should get you somewhere close then just play with the values to get what you want, paying attention to the manual. --set bfl:_cmd1=F9X --set bfl:_cmd1=V10X One important note to get this working, for me, I have to first run BFGMiner with the above parameters which loads up as 0Gh. Then press 'q' to quit and re-run BFGMiner as normal without the parameters. It should now run with the lower hash rate. To reset the speed just power off the miner for a couple of seconds then restart it as normal. Hope that helps, KOR Hi, I have many monarchs and run them underclocked. I get, with 80+ bronze power supplies, about 500Gh/320W at he wall. Here are my settings: --set bfl:_cmd1=F5x --set bfl:_cmd1=V6X This sets the voltage at 0.63V. Also, I have the best luck by executing bfgminer with this setting, waiting until the "temp" shows then closing it and reopening with no voltage/freq command. Just make two seperate shortcuts for this. Hope this helps.  |

It still would be nice if the OP would check in here from time to time, update the thread title hashrate, post updates. I personally don't use Facebook at all.

I noticed OP hasn't logged in since October 2015. Not a good sign.

Hi, what does
"BFL 4aa: Received queue result response: ERR: INVALID COMMAND" mean?
After this happens the miner slows down and when I press quit it takes a long time to release/shut down/get a command prompt again.
This happens once, twice, three times or not at all for more than 24 hrs. It's random and I'm trying to figure out what is doing this.
I'm using bfgminer 5.2.0 and it does the same on the latest version too. I was trying the earliest version that will run all the monarchs because it's like someone changing the voltage because it's the same if I made a change in the current version of bfgminer and they don't like it and when I quit it take a while before I get the command prompt back.
This has been happening for about two months now.
OS Arch Linux, ample power, original USB cables.
Any help or anyone else having this problem?
Thanks
Is this a problem with a Monarch? What firmware version does it have? I have found that firmware version 1.4.5 works great with BFGminer 5.0.0 and up but older firmware versions can be tricky. Also, are you using a USB hub? |

is everything ok now ?
I have a question about the rewards system.
I have recently pointed my 4x Antminer S7 to kano but I can see the rewards I get per block solved are very low.
I noticed N average gets higher and higher every time, I am mining with approx 19 Th/s and my N average got to about 14 TH/s in 4 days of mining.
How does this work ? Can this N average get even higher than the power I am mining with ?
Yes it takes approx 5 days to get fully up to speed. Then you wil get full reward per block.> but in the same token if you leave for five days you wil get reducing rewards .. it will all work out:) Best Regards d57heinz So in order to get full power I need to "sacrifice " 5 days ? Why does it work like this ? You will continue to receive payouts if you leave, so it averages out. |

Phew! Now lets get a few bright green ones  t So we get a valid block and almost 1ph leave the pool? Why would one pool hop here with a 5N? Hopping works well at slush, but why here. Don't get it. Stay after a block and keep hash high to get the next block faster. It's nothing new actually. That's the strange thing about it. Often in the past I've seen the hash rate drop after we find a block. I've no idea why miners leave then. My hashrate shows lower right now even though all of my miners indicate normal rates. Slowly creeping back up to normal poolside though. Edit: looks like my miners switched to my backup pool. Maybe that is why 1PH left after the block change, their miners switched to backup pools. |

I still have a bunch of these. Think I have quite a few gold ones. Also have an "early" red on that is a different shade of red than the later ones. When I get home
(7 PM EST) I will look.

I managed to find a proxy I can use. Brought 17Th to the pool.  Edit: Running a proxy does result in slightly higher stales (0.5%) |

Hi.
Does this software support different difficulties for users?
Thanks!

I Got 2 controllers, so can point them at 2 different places where ever you want them. They Are just turned OFF atm..
Just use ckproxy. That was suggested to me since I can't use CGminer. That Works? It might. What I did when I had tubes mining is use a uart adapter and a custom version of cgminer. I think there was talk of a r-pi image created by "crazyguy" back when he sold tubes. |

Anybody got any explanation for this jump ? Its like nothing ive seen in the past. Im quite shocked actually.
Most likely Antpool. They have almost 25% of the entire network.  |

Might not be very safe wiring the outputs of two power suppiles together. Diodes might be in order.
They're made for it, so long as the load sharing pins are connected together allowing them to communicate with each other. Hmm, that's interesting. I have some of these left over from a Terraminer. Sounds like you can basically make a "2200w" power supply out of them. |

Back on Bitcoin.cz for now. As one would expect, contacting BFL is futile. I apologize if this caused any disruption to this pool. I really do like this pool, but ALL
I have are monarchs. Maybe sometime down the road, I will be able to use CGminer with my cards.
Running all your monarchs into a local proxy will clean out the crap before it gets to the pool. ckproxy is ideal for that. helipotte, yeah if you could switch over to ckproxy that would be good. Though that requires linux also. No apology required. You clearly didn't realise what was going on and that's why I brought it up in email. I've not banned you or anything No probs here. Maybe I could try setting up ckproxy on a R-pi. Have plenty of those laying around now. BTW, just got your email, I don't usually check it until later. Edit: I see it is 64bit only, so no r-pi proxy. |

Odd. I have a Monarch I can run with no issues at less than 1% error rate if I underclock at 555GH@280watts usage. I use BFGminer or easyminer with no issues.
I don't have an issue with errors. I have one instance running 24 monarchs. Everything works fine but the host CPU overhead in BFGminer is very high. |
